FIELD: process engineering.
SUBSTANCE: invention relates to iron and steel industry, particularly to production of charge billets in blast-furnace plant. Proposed mould comprises body wide side and crosswise baffles. Mould comprises two cells with horizontal bottom. Bottom sides relate as follows: α/ℓ = 1:1.25. Mould lengthwise baffle represents a spherical segment with radius R1 equal to 0.31-0.35 of cell bottom side ℓ. Cell side surface opening angle α on cell bottom side α equals 60°. Cell side surface opening angle β on cell bottom side ℓ equals 65°. Mould thickness δ makes 0.22-0.25 of cell bottom side ℓ.
EFFECT: higher quality and mechanical strength.
