Continuous rolled-steel heat treatment equipment

Abstract

The invention relates to the technical field of rolled-steel heat treatment, in particular to continuous steel heat treatment equipment. The continuous rolled-steel heat treatment equipment comprisesa preheating mechanism, a heating mechanism before quenching and a quenching mechanism, wherein the preheating mechanism is used for preheating continuous rolled-steel before quenching; the heating mechanism before quenching is arranged on the side part of the preheating mechanism, receives the continuous rolled-steel from the preheating mechanism and is used for performing the thermal quenching and tempering process on the continuous rolled-steel before quenching and heating the continuous rolled-steel to 800-1000 DEG C; and the quenching mechanism is arranged on the side part of the heatingmechanism before quenching, receives the continuous rolled-steel from the heating mechanism before quenching and is used for performing the quenching process on the continuous rolled-steel and quenching the continuous rolled-steel after quenching and tempering. The preheating mechanism and the heating mechanism before quenching are arranged, the continuous rolled-steel can be heated to 800-1000 DEG C, the quenching mechanism is used for quenching the continuous rolled-steel after quenching and tempering, and most of austenite in the continuous rolled-steel can be transformed into martensite.

Description

technical field [0001] The invention relates to the technical field of steel heat treatment, in particular to continuous steel heat treatment equipment. Background technique [0002] Chinese patent CN201720580909.8 relates to a kind of quenching processing equipment, especially a kind of carburizing and quenching equipment for metal workpieces. The heated workpiece of the quenching processing equipment slowly enters the quenching oil pool after falling from the discharge port and buffering the blanking parts. And it falls on the cooling section of the workpiece conveyor belt, and gradually cools as the cooling section runs slowly, and then is transported out of the quenching oil pool through the transfer section to complete the quenching process; in the carburizing and quenching process of steel, austenite is transferred When the state becomes martensite, the area fraction of the martensite structure on the surface of the steel piece cannot be significantly increased, so in ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a continuous steel heat treatment equipment. This technical solution solves the problems of low safety and low efficiency of manual pick-and-place during the gear quenching process. Setting, the continuous steel can be heated to 800-1000°C, and the quenched and tempered continuous steel can be quenched by the quenching mechanism, and most of the austenite inside the continuous steel can be transformed into martensite
