FIELD: metallurgy, namely, continuous casting of steel to mold through tube. SUBSTANCE: apparatus for changing tube mounted on distributor for continuous casting includes refractory parts restricting pouring duct, at lest one stationary mounted support and tube. Drive unit moves new tube from inlet position to casting position and moves worn tube from casting position to removal position. Stationary mounted support has cylindrical convex surface with axis normal relative to direction of large size of mold. In upper portion tube is provided with cylindrical concave plate whose shape corresponds to cylindrical convex surface of stationary mounted support. Unit providing mechanical pressure forces plate of tube to stationary mounted support in such a way that plate slides under pressure while keeping fluid-tightness of contact zone between concave and convex surfaces. EFFECT: simplified process for changing tube without use of expensive manipulators. 11 cl, 3 dwg
