Design of a flame torcreting unit for hot repair of a heating unit lining is developed. A unit with a capacity of 1800 – 2000 kg/h successfully passed tests for melting slag and skull from the surface of a repaired lining, and applying torcrete masses to the tuyere belt of a horizontal converter lining, and the slag belt of metallurgical enterprise power plant furnaces. Compositions of SHS-materials for the production of masonry mortar, torcrete mass for flame torcrete, and technologies for their manufacture and application, as well as laboratory and semi-industrial torcrete installations, are developed. SHS-materials are tested in the lining of heating units of Rezhnickel CJSC, Ufaleynickel OJSC and Ust-Kamenogorsk metallurgical complex, and show good physical and chemical properties. Tests of new torcrete installations and torcrete mixes in non-ferrous metallurgy enterprises show an increase in lining durability by a factor of 1.8 – 2.5.
