Hebei iron and Steel Group Steel Vanadium Titanium Bearing Based on the technological innovation department constantly optimize the recycling process of the production process. The latest statistics show that the division of 50 FEV production process optimization, effectively extending the vanadium iron furnace body service life of refractory material, the annual drop fee of 20 million yuan.
Since 2015, bearing steel vanadium division for control indicators improve, upgrade products, cost reduction and other problems alkali than qualified rate, rotary kiln transformation rate, rotary kiln feeding amount of key indicators such as research, doctoral, graduate student, "settle down" production line as an opportunity, through the implementation of scientific research project project responsibility system, give full play to the role of academic leaders, combined with the actual production, conducted in-depth technical research. Refractory drop fee research process, technical personnel in-depth study 50 ferrovanadium refractory lower fees new technology, replaced the fine slag ladle material, and furnace body a slag outlet tilt angle is adjusted, so as to prevent the slag erosion of the arms package, prolong the service life of the slag ladle service life, and to reduce the consumption of refractories.
