Background

The steel smelting is a general term of steel and iron metallurgy process. Iron produced industrially is classified into pig iron (containing carbon at 2% or more) and steel (containing carbon at less than 2%) according to the carbon content. Most of modern iron making adopts blast furnace iron making, and a direct reduction iron making method and an electric furnace iron making method are respectively adopted. The steel-making is mainly made by using pig iron smelted by blast furnace, sponge iron smelted by direct reduction iron-smelting method and waste steel as raw materials and smelting them into steel by different methods. The basic production process is that iron ore is smelted into pig iron in an iron-smelting furnace, then the pig iron is used as raw material, and is smelted into steel by different methods, and then the steel is casted into steel ingot or continuous casting billet.

The smelted alloy steel can be processed by a flying shear, which is one of shearing machines and is used for transversely shearing a moving rolled piece. Flying shears are used mainly for shearing medium and small steel billets, thin slabs, small section steel (bars) and hot and cold rolled steel strip (including coated). Also be used for the flange limit that the disc shear sheared off to cut up (promptly the scrap chopper), current flying shear can not adjust the height of its workstation, inconvenient removal moreover, has certain drawback, awaits urgent need the improvement.
