As a new member of the family of Ansteel engineering machinery steel, the steel for shield machine shell is called "the king of modern underground engineering". New orders have been made by the customers after the product was put into use successfully. So far orders of 190 tons of steel have been made, which will bring new power for survival and development of business.


    Shield tunneling machine is the high-tech tunnel construction equipment integrated with many technologies such as light, electricity, liquid, sensing and IT. With the accelerating pace of construction of China’s metro, high-speed rail and urban rail, the shield machine industry has been rising up rapidly in recent years. The market has promising prospect.

 
    The steel has the biggest thickness among the certified product series of Ansteel at present. It is required to have better mechanical property, welding property and Z-direction property. And the level of flaw detection shall conform to European testing standard. After having received orders, the product development department of Angang Steel Co. Ltd. organized Ansteel Steel Casting Company, Bayuquan Branch of Angang Steel Co. Ltd. and Iron and Steel Research Institute of Ansteel Group to cooperate closely in respect of production, marketing and research, make relevant  technical solution, ascertain chemical composition and technical indicators, follow up the full process including ingot purchasing, planning, production scheduling, rolling, flaw detection, product inspection, to ensure one-time pass rate of product flaw-detection, performance testing and the delivery date of large heavy thick plate.
