MOLD FOR CONTINUOUS CASTING OF STEEL FOR MAKING PIGS AND INGOTS Russian patent published in 2005 - IPC

FIELD: metallurgy.

SUBSTANCE: mold for continuous casting of steel at making pigs and ingots includes inner housing cooled with cooling fluid and having molding cavity 4. Inner housing includes base 6 for coating made of aluminum or its alloy and provided at side of molding cavity with coating 7. The last after its applying onto base 6 in molding cavity 4 is worked until size of molding cavity. It is preferable to add in coating 7 matters for lubricating skin of casting such as MoS₂ and (or) WS_2. Thickness of coating may be in range 0.5 - 5 mm, preferably 2 - 4 mm. In upper part of molding cavity coating 7 may be of copper or its alloy with heat conductivity 200 - 400Wt/m x K and in lower part of molding cavity it may be of nickel.

EFFECT: lowered costs for making tubes of mold, increased useful life period and heat power of mold.
