To further expand the market and increase the variety of remelting steel, recently, the stain-steel mill of Xingtai Steel successfully developed and produced LZ50 Axle Steel for high-end railway vehicle through ESR. It is a kind of high-quality specialty steel and the smelting of this steel is very difficult.

　　This steel is a kind of quality carbon steel with high strength index and high plasticity index. It needs high flaw detection quality. The internal defects also should be strictly controlled in the smelting process

　　This exploitation makes full use of our company’s advanced equipment and accurate control performance. We made a smelting production plan carefully and produced qualified remelting ingot which has smooth surface, uniform composition, high cleanness for many times.

　　The successful production of this steel marks electro-slag technology of our company has reached a new height. This type of steel became a new member of specialty steel in Xingtai Steel.
