Synopsis : The No.3 continuous slab caster of Chiba Works, Kawasaki Steel Corporation has been operating satisfactorily since its start in April, 1981. In order to cast slabs of sound internal quality at high speed, this machine has a 3-meter-long vertical portion, a progressive bending and unbending profile and small roller pitches with divided rollers. The machine also has an equipment for a quick test scarfing to see if slabs are good for charging hot into the heating furnace. Hydrogen content of steels melted by Q-BOP are rather higher than those by LD; posing problems of slab surface defects which, however, are now solved by improvement in Q-BOP operation. |
