[0032] Examples:
[0033] Method for refining molten steel by blowing argon gas in a 5-ton alkaline intermediate frequency induction furnace for smelting manganese steel without oxidation
[0034] Refer to figure 1 , 2 The intermediate frequency induction furnace with argon blowing in the furnace is composed of furnace cover 1, furnace lining 2, crucible 3, gas diffuser 6, filling 7 and union 8, slag 4 and molten steel 5 in crucible 3, argon blowing system It consists of an argon cylinder 10, a pressure reducing valve 11, a flow regulator 12 and a pressure-resistant rubber tube 9. The refining process is:
[0035] 1. Knotting the crucible, use the furnace lining material and the furnace neck material to tie the lower crucible and the upper furnace collar respectively, and install a gas diffuser at the bottom of the furnace and bake and dry;
[0036] 2. Ingredients and loading: According to the chemical composition requirements of manganese steel, calculate the ingredients and load the...
