Procedure carburising gas and apparatus therefor.

THE MATERIAL TO BE TREATED (W) is preheated to a temperature of carburization 750 (degrees) - 950 (degrees) CY heat treated in an atmosphere of carburizing DIRECTLY SUPPLIED WITH GAS OIL AND oxidizers, IN WHICH HEATS UP 1000 (DEGREES) -1100 (DEGREES) C. Then the material being TREATY (W) is cooled FORM FORCED to a temperature below 600 (DEGREES) C, the material (W) is reheated to 750 ( GRADES) -850 (degrees) CY THEN YOUR hardened by oil quenching (20), preferably using a technique of TEMPERED laminar flow hood.
