The establishment of "Hot charge rolling process (HCR)" at No. 3 caster in Kashima Steel Works has led to much higher productivity, energy saving and improvement of material flow. In HCR, cast slabs are directly put into the reheating furnace and after a short time, they are rolled by the hot strip mill. The following technological developments and new systems were implemented; high speed casting technology, high temperature slab discharging technology, technology for width change during casting, slab quality assurance system and production control system.
Since it has started up in June, 1983, HCR has been running satisfactorily. The latest production amount reaches 270 kt/M and the ratio of hot charge rolling, exceeds 80%.
