FIELD: metallurgy. SUBSTANCE: mold has two first wide cooling side plates made with formation of convex part in mold and second narrow side plates located between them installed rigidly or for possibility of regulation depending on width of casting. Convex part is formed due to making the first side walls with concavity nonlinearly passing from one to other side plate of mold through middle line of mold, and located on section of mold height with beginning in any point of upper section equalling 80% of mold height, in particular, 30% up to mold outlet hole. Shape of concavity of the first side walls in direction from middle line of mold to second side plates is presented in form of a part of circumference with radius of concavity on its ends which are connected to each other through point of turning. Due to convex shape of mold, casting during its casting at rate of up to 6 m/min is centered in mold to suppress or cushion side motion of casting during pouring of metal into mold leads to uniform symmetrical structure of shell of casting, its temperature field, pulling force and load on casting shell with respect to article axis in direction of casting even in shaking of casting in zone of casting guiding. EFFECT: higher efficiency. 2 cl, 1 dwg
