Title:
PRODUCTION OF THIN CAST SLAB HAVING GOOD SCALE PEELABILITY
Document Type and Number:
Japanese Patent JPH0825001
Kind Code:
A
Abstract:
PURPOSE: To provide the production method of thin cast slab which is easy to remove scale before hot rolling in order to produce the hot rolled product having no surface flaw in producing hot rolled product from thin cast slab.
CONSTITUTION: In a belt continuous casting method, by using the belt coating material having 20% or more content of one or ≥2 kinds among metallic Al, Ti, Zr, La, Ce. Al are concentrated in the surface layer of cast slab so as to increase a melting point of the low melting point fayalite oxide, which is a cause for hard scale peelabilty of a Si containing steel and a thin cast slab having good scale peelabilty is obtained, accordingly a hot rolled product having no surface flaw is produced.
