Seamless steel pipe production line of the main cooling bed type

Seamless steel pipe production line of the main cooling bed types have Single strand cooling bed, Duplexes cooling bed, New Chain cooling bed, Stepping rack type cooling bed and Screw type cooling bed.

1. The single-stranded cooling bed

Single strand cooling bed more adopts climbing structure. Cooling bed composed by forward transport chain and fixed rail, with a set of transmission. Steel pipe placed in the forward transport chain, fixed rail bear the weight of steel. Single-stranded cooling bed use driving force of forward transport chain and friction of fixed rail to rotate the steel pipe, while relying on steel weight and the angle of lift, to make the pipe always closed in the forward transport chain, achieving steel tube rotates smoothly.

2. Duplexes cooling bed

Duplexes cooling bed composed by the forward and reverse transport chain, forward and reverse chain with a set of transmission. Steel pipe placed in the forward transport chain, reverse chain bears the weight of steel. It use driving force of forward transport chain to run pipe, and using the friction of reverse chain to make the steel pipe carry on a continuous rotational movement. Movement of the reverse link makes the pipe always closed in the forward transport chain, achieving steel tube rotates smoothly and uniform cooling.

3. The new chain cooling bed

A combination of the characteristics of single-stranded and double-stranded cooling bed, the cooling bed is divided into uphill and downhill sections. Uphill section is a double-stranded structure composed by forward and reverse transport chain, positive and negative interaction together to make steel continuous rotation and forward, doing climbing movement. Downhill section is a single chain structure composed by the forward transport chain and steel rails, relying on weight to achieve rotation and landslide movement.

4. Screw type cooling bed

Screw-type cooling bed is composed by gearing, screw and fixed cooling stand and so on, screw including screw rod core and screw spirals. Fixed cooling bench face is higher than top of screw rod core and below screw spirals, the weight of steel bear by fixed cooling stand. Main gearing driven screw synchronously rotating, screw spirals pushed steel to roll forward in fixed cooling bench.

Single-strand cooling bed is not suitable for continuous operation, duplexes cooling bed has a better effect, New Chain cooling bed has a good effect and low cost, Stepping rack type cooling bed is generally used in large or high configuration of production line, Screw-type cooling bed for cooling generally smaller diameter of the pipe.

Japan has strengthened steel for offshore wind power research

Recently, the Japanese national project "Floating form of offshore wind power research" of the launching ceremony was held in Fukushima Onahama Port. The project of floating form offshore wind platforms mounted on 20 kilometers outside of Port Onahama, shipped from Chiba of 2MW wind power equipment will be combined with the 66kV substation floating body binding shipped from Yokohama, and recently officially to run and generate electricity.

This project is participated by NSSC, Japan JMU (Japan Marine United) company, Mitsui shipbuilding etc. 10 enterprises and the University of Tokyo. NSSC is primarily responsible for the development of high-performance steel. The project of 2MW Floating form of offshore wind power equipment requires high strength plate of 2000 tons. In the field of ocean energy steel, NSSC can take advantage of shipbuilding plate processing technology, in achieving high welding workability, cost reduction at the same time, fully considering the impact of wind wave adaptability, and the development of new steel materials.

The project is scheduled to start 7WM floating form of wind power projects in next year, each machines required 3,000 tons of plate, with wire and rod totally mounted about 20,000 tons. As new materials of the world's largest offshore wind power equipment, required both the performance of high strength and high toughness to meet structure requirement of marine wind power. In the process of popularity of offshore wind power, the production cost is also very important, so it must vigorously reducing costs while ensuring excellent performance. Meanwhile, in the offshore construction need to consider the weather conditions. In order to shorten the construction period should greatly improve the steel welding performance and workability. The strength of steel must have resistance of seawater and wind. Britain is studying the construction of seabed fixed wind power, this requires more steel, therefore, the global offshore wind power market prospects timber.

NSSC engineering company is very concerned about offshore wind power project, in order to exert its marine towing and tethered etc. marine construction advantages to explore new markets. In this project, 2MW Floating form of offshore wind power equipment from Tokyo sea lead to Fukushima fixed, now is taking enhanced measures. The company will focus on strengthening the development of marine wind power projects, intends to use existing strengths to enhance the design, equipment manufacturing and construction, especially for floating form of offshore wind power from traction to fixed mooring of the main construction work carry out full summary, to promote the rapid development of the company's business.

September U.S. steel imports from China increased significantly

U.S. Commerce Department released data show, September 2013 U.S. imports 2.505 million tons of steel, month to month dropped by 4.1%, compared to last year growth of 6.1%. 1-9 months total steel imports 21,674,000 tons, year on year drop 7%.

From species to see, compared with last year, the growth rate of rebar is biggest, reached 155 percent, hot rolled growth of 24.4%, galvanized sheet increased by 11.9%, but the steel pipe, wire and plate has a larger decline. Compared with August, there are larger increase in rebar and plate, steel pipe, wire rod and cold volumes has larger decline. From import source countries and regions to see, compared to last year, there are larger imports growth from Central and South America, Japan, China and Turkey, and imports from the CIS and EU decreased significantly. Compared with last month, imported from Japan, China and Turkey imports increased significantly, from North America, South America, South Korea and the CIS decreased greatly. September U.S. imports 176,500 tons of steel from China, month to month growth of 76.88%, compared to last year increased by 89.4%.

The latest statistics show that until to October 25, 2013, October U.S. steel import license number is 127 million tons, which much lower than the same period value in September, U.S. steel imports is expected to significantly decrease in October.

Japan's crude steel output of this year hit a five years record high

According to the latest forecast of the Japanese Ministry of Economy, Japan's crude steel output of this year is expected to increase to 111 million tons, compared to last year growth of 3.1%, and hit a five-year record high. The main reason is government to increase infrastructure spending and housing construction.

Recently, the Japanese Prime Minister expressed, April of next year the consumption tax from the current 5% is raised to 8%. At the same time, increasing infrastructure spending to stimulate the central bank to take more forceful measures to end deflation. Since taking office last December, Japanese Prime Minister funding at least 10 trillion yen for infrastructure upgrades. In addition, the Japanese construction continues to increase, including the Northeast reconstruction projects after the earthquake in March 2011.

Benefited from strong demand for steel and depreciation of the yen, Japanese steel share price and profit rose, including Japan's largest steel producer NSSC Company and JFE Steel Corporation. Since the end of last year, the Japanese yen against the U.S. dollar fell by about 20%. Depreciation of the yen not only prevented imported resources from Korea and China etc. Asian countries, while helping Japanese manufacturing regain competitiveness in export markets, causing domestic steel manufacturers work hard to increase production.

India's "12th Five Year Plan" steel production capacity difficult to complete

Recently, foreign media reports, Due to the current economic slowdown makes the steel mills in India postponed to expand production capacity, meanwhile the Indian government delays in the approval of new projects, will make India's steel industry difficult to achieve previous setting of the "12th Five Year Plan" steel capacity growth targets.

Indian government's "Twelve Five" (2012 - 2017) plan say that, Indian steel production capacity from the current 90 million tons increase to 142.3 million tons in 2017.

India, a securities analyst said that it is clear that India can’t achieve steel production capacity of 142 million tons of goals in 2017. The vast majority of Indian domestic steel companies have delayed the expansion of production capacity, estimated that India's steel production capacity can‘t exceed 100 million tons to 1.05 million tons.

India's "Twelfth Five-Year Plan" relevant documents show that with India's gross domestic product (GDP) to maintain growth of 9%, steel consumption is expected to grow by 10.3%, on this basis the 2017 Indian steel production target is set at 142.3 million tons. India-related industry sources said that the target is indeed high, because this data is established on sustained GDP growth of 8% in the basis. According to Rao, India Commercial Bank chief economist introduces the next three years, the average growth rate of India's GDP expected to be 6%.

Due to steel construction project approval delays, as well as environmental permit applications and other unfavorable factors effect, India's steel production capacity increase has emerged signs of deceleration. According to analyst introduced, like Tata Steel, JSW Steel and Steel Authority of India and other Indian steel companies are also facing the problem of delays and postponement. Although India's steel companies have announced before the "twelfth five" increase71 million tons of steel production capacity, however, due to the lack of project delays or regulatory permits, this will be the uncertainty of future production capacity.

Indian steel prices may rise

Future steel prices rose mainly due to:

First, the Indian government approved a series of infrastructure projects that will lead to rising steel demand in the coming months.

Second, in October, the Indian state-owned bank announced that it would cut 0.20 percent interest on the car, within three years to buy a new car the lending rate is 10.45% -10.75%. India's largest car manufacturer Maruti Suzuki India has announced its October car sales rose 1.91 percent, reaching 105,087 units, and according to the analysis in the next few months, sales will continue to rise.

Third, the Indian government has injected 140 billion rupees to state-owned banks, This will encourage banks to lend in the coming festive season to stimulate consumers to buy cars and consumer durables.

Finally, the Indian rainy season ends, the new construction activity will increase.
