METHOD OF SECONDARY COOLING OF METAL AT THE CONTINUOUS CASTING OF CAKES OF SQARE AND RECTANGULAR SECTION Russian patent published in 2012 - IPC B22D11/124

Abstract RU 2441731 C1

FIELD: metallurgy.

SUBSTANCE: method includes cooling of the cake by sprayed cooler, change of cooling medium consumption along the secondary cooling zone depending on the speed of cake drawing and regulation of cooling intensiveness by cyclic supply of the cooler. The cycle period is calculated according to the formula T=τ₁+τ₂, time of cooler feed - according to the formula: τ₁=(L*α₁*α₂)/ (V*100), shutdown time of the cooler feed - according to the formula: τ₂=(L*K1)/(V*100), and liquid phase length - where a, b - sectional dimensions of cake, V - metal casting speed, α₁ - coefficient connected to the content of carbon in the steel, α₂ - coefficient connected to the content of alloying additions, K₁ - coefficient connected to steel grade, K₂ - coefficient of steel hardening, mm*min^-0.5.

EFFECT: cooling of the cake by sprayed cooler.
