Process for producing thin cast strip

Molten metal is supplied to a pouring basin formed between cooling members, such as movable cooling drums. A closed space is formed at a meniscus area whereat any one of the cooling members starts to come into contact with the molten metal, and a soluble gas or a mixture of soluble and insoluble gases is supplied to and filled in the closed space, thereby covering the meniscus area with the gas or the mixture. This arrangement enables a continuous casting of a thin metal sheet without surface cracks and having excellent surface characteristics.

Method and apparatus of continuously casting a metal sheet

A method of continuously casting lead-bearing steel by adding lead to steel melt in a tundish. The tundish is divided into a plurality of chambers including a melt receiving chamber and an immersed nozzle chamber, lead is supplied to the molten steel in a chamber other than the immersed nozzle chamber so as to form a lead sediment layer at the bottom thereof, and molten steel containing suspended Pb is passed to the immersed nozzle chamber from where it is poured into a mold of the continuous caster.

Method of continuously casting lead-bearing steel

Process for producing austenitic stainless steels, which process prevents occurrence of rolling defects, particularly slivers. Specifically, process for controlling casting conditions on the basis of nitrogen contents in the molten steel and further controlling hot working conditions including heating conditions and working temperature.

Process for producing austenitic stainless steels less susceptible to

Process for continuous casting of a steel slab free from surface defects, which comprises oscillating a mold under an oscillation condition which restricts the deformation of a meniscus portion of a strand shell so as to prevent oscillation defects.

Continuous casting of steel slabs and blooms free from surface defects

A casting powder to be used for ingot casting and continuous casting of steel which contains substantially no carbon particles. It contains, instead of carbon particles, BN or other nitrides as an agent for adjusting fusion rate of the casting powder so as to fully prevent carburization and carbon pick-up caused by the carbon particles which has heretofore been added to the powder for control of the fusion rate. This new casting powder may contain a reducing agent in addition to the nitride.
