FIELD: metallurgy; designed for continuous casting of thin steel ingots. SUBSTANCE: mold has two opposite walls from wide sides each consists of copper plate and steel supporting plate. Copper plates restricting cavity of mold are detachably secured to supporting plates by means of metal bolts made of CuNiMnFe alloy. Metal bolts are welded to copper plates. IN this case, additionally used is ring from nickel as welding additive. Made in copper plates are channels for coolant. Holes for cooling are made in zone of planes of cross-section of metal bolts. EFFECT: provided higher strength in zone of joint of metal bolts with copper plates. 12 cl, 5 dwg
