FIELD: technological processes. ^ SUBSTANCE: invention refers to the sphere of metallurgy. Gate channel is arranged with gap into metal jacket and fixed. Liquid self-hardening mixture is poured through gap into volume produced between external surface of hollow fireproof gate channel and inner surface of metal jacket for not more than 15 minutes after its preparation. Liquid self-hardening mixture contains components at the following ratio, wt %: dust of gas cleaning of electrothermal production of silicon 48.4-65.2, wastes of electrothermal production of crystalline silicon 0.8-2.4, aluminium powder 0.8-2.4, liquid glass 30-50. ^ EFFECT: manufacturing of hollow fireproof gate channel of required configuration and external metal jacket. ^ 3 cl, 2 dwg, 4 tbl |
