The new continuous caster at No. 1 steel-making shop in Kashima Steel Works is the low head typemultiunbending machine (SH-CCM).
Kashima Steel Works already has two units of big S-type continuous caster with two strands. And the production ratio of slabs by these two casters reaches approximately 60 percent of the total production in Kashima.
One of the main purposes to develop SH-CCM is to utilize the old top pouring deck for the conventional ingot making process, which is not used recently. The other is to produce rather inefficent lots for a big caster, such as the one with small amount or with a special size, in order to maintain high productivity of the main conventional casters.
The construction of this machine is more economical than that of a conventional caster since it is possible to utilize various facilities of the old ingot-making deck.
SH-CCM has many features, such as approximately 5.8 m in machine height, which is far smaller than that of the conventional caster, five successive unbending points, wide range in size and single strand which is applicable to both slab and twin-bloom casting.
The new caster has been running satisfactorily since its start-up in July 1979 and the quality of products is by no means inferior to that of conventional casters.
