METHOD FOR MANUFACTURE OF CONTINUOUSLY-CAST BLANKS Russian patent published in 1995 - IPC

Abstract RU 2033885 C1

FIELD: metallurgy. SUBSTANCE: method involves determining the time of metal temperature stabilization in intermediate ladle and calculating for this time the temperature of metal T₂ C in pouring ladle from the relation T₂= T_I-K¹·(Δτn2

^′- Δτ₁n′) where T₁ - temperature of metal in the pouring ladle during extrafurnace treatment, C; Δτ₁ - metal holding time in the pouring ladle corresponding to T₁ temperature, min; Δτ₂ - metal holding time in the pouring ladle corresponding to metal stabilization temperature in intermediate ladle, min; K¹ - proportionality coefficient K¹ = 0.4 - 8.4, C/min; n¹ - factor of degree n¹ = 0.6 - 0.8, and changing the blank drawing rate V according to the relation given in the description. EFFECT: higher efficiency. 1 dwg
