Recently, the first specialized production line in our country of high strength ,super lighted , super-small H beam production , designed and manufactured by Tianjin Zhongzhong science and technology engineering Co., LTD, got the successful commissioning of heat load in Dalian Zhengda wheel Co., LTD.
This marked that our country has developed the super-lighted H-beam professional production line by ourselves. Super-lighted H-beam production is our country H-beam production field blank. With the rapid development of our country’s economic construction, the market for super-lighted H-beam needs became more and more prominent.
In October 2007, Dalian Zhengda wheel Co., LTD entrust in Tianjin Zhongzhong science and technology engineering Co., LTD designed and manufactured a production super-lighted H-beam rolled production line for him. Which has long-term commitmented to domestic universal H-beam rolling mill developed and have successfully developed to create many H-beam production line for the domestic several steel enterprises.
Hot-rolled frivolous H-beam production line has high standard in the production equipment, and technical performance requirements , but the hot rolling super-lighted H-beam production line need the higher standard production equipment , technical performance and production process requirement. The designers of Tianjin Zhongzhong science and technology engineering Co., LTD have manufactured researchers for 1 years and more, and conquered a series of technical problems. Finally they built the first specialized production line in our country of high strength ,super-lighted , super-small H beam production, and achieved successful commissioning in the first test. Every performance indicators completely meet the technical requirements. This a independent innovation achievements, not only to fill the gaps in the project of the domestic blank, but also adapt to the market demand of our country. It has an important meaning for the development of production equipment H-beam and H section of industry development.
In the GB/T11263 HT, the most thin waist thick of 100×50 series light H-beam is 3.2 mm, the most thin leg is 4.5 mm thick. But the super-lighted H-beam, designed and manufactured by the high strength ,super-lighted , super-small H beam production line of Tianjin Zhongzhong science and technology engineering Co., LTD, has successfully meet the national standards X57mm 102—-webs and flange plate thickness only 2.3 mm respectively and 3 mm and achieved the bulk production ability. This H beam production line rolled out the thiner specifications of the products than national standards and its technical level and production capacity has reached the domestic leading level.
In addition, the application of super-light H-beam has more than 50% saving effect of the materials and widely used in light cars and light steel structure. It can significantly reduce the cost, reduce downstream industry structure and improve the weight structure strength, conforms to our country saving energy and reducing consumption and the strategy of sustainable development.
