Product details
By 50 t, 3 LF electric arc furnace smelting furnace t electrode, electroslag remelting, insulation, annealing, 800 /650 * 4 mill production process leaves Phi 180 steel refining, casting (%: 0.06 ~ 0 15C, 0.25 ~ 0.80M 11.25 ~ 13 n, 00C R, M o = 0.30, 60N = 0 I less than or equal to 0, 025P, 0.010S). The electric furnace smelting ingredients into the dephosphorizing agent, Bachu all LF dross. After refining argon blowing, A line and C a - S I line were finally deoxidized. After analysis, the technical indexes meet the standard requirements
