FIELD: metallurgical equipment. SUBSTANCE: method involves increasing temperature in well at constant flow rate and combustion heat of mixed gas and holding at blistering temperature, with fuel combustion heat being reduced by reducing supply of high temperature combustion gas for mixing. When temperature in heating pit is increased from metal heating temperature of blistering temperature of, high temperature gas heat is set from dependence recited in Specification. EFFECT: high-quality heating and reduced consumption of fuel. 1 dwg, 1 tbl
