1200 DEG C of ± 20 DEG C of soaking 5-7h, in stove total time >=16h；
Steel ingot thickness≤700mm, is applicable 14t≤ingot shape ＜ 20t, and 750 DEG C of shove charges are incubated 5h-6h, 750-1240 DEG C of heating 6-
8h, 1200 DEG C of ± 20 DEG C of soaking 7-9h, in stove total time >=18h；
2) 700mm ＜ steel ingots thickness≤900mm, 20t≤applicable ingot shape ＜ 40t, 750 DEG C of shove charges are incubated 7h-10h, 750-
1240 DEG C of heatings 6-9h, 1200 DEG C of ± 20 DEG C of soaking 9-11h, in stove total time >=22h；
3) 900mm ＜ steel ingots thickness≤1000mm, 40t≤applicable ingot shape≤60t, 750 DEG C of shove charges are incubated 7h-10h, 750-
1240 DEG C of heatings 10-12h, 1200 DEG C of ± 20 DEG C of soaking 10-21h, in stove total time >=27h.
Compared with prior art, the beneficial effects of the invention are as follows：
Appropriate adjustment steel ingot preheating section and high temperature section time, on the premise of Heating Steel Ingots quality is ensured, greatly improve life
Produce efficiency and gas utilization rate.
