Refractory for secondary steel making
Monolithic in jectiong lance for argon blowing:
Monolithic in jectiong lance is made from casting refractory material around the steel bar,it has the nature of high strength,fine erosion-resistance.our factory have built advanced equipment to make all kinds of injectiong lances for smelting steel's usage of desulphoriztion.Technical standars will be discussed between the maker and the customer.
Quality standard of monolithic injectiong lance:
Monolithic lance for hot metal pretreatment
Lance for TN ladle powder injection
Monolithic lance for secondary steelmaking in LHF,etc.
