Problems solved by technology

However, if the steel with concave structure is preheated, unnecessary internal stress may be generated due to uneven heating of the steel, and the desired structure may not be produced in some positions; at the same time, in During the quenching process after preheating, the surface of the steel will produce an oxide skin that is easy to fall off

Abstract

The invention relates to a heating and quenching device for steel with a concave structure, which comprises a preheating furnace, a quenching tank, a tempering furnace, an auxiliary preheating unit for uniformly heating the steel subjected to heat treatment, and a clamping unit for transporting the preheated steel to the quenching tank, wherein the auxiliary preheating unit is arranged in the preheating furnace; the tempering furnace is located on the stroke of the clamping unit; the auxiliary preheating unit can enable the steel with a concave structure to be evenly heated in the preheating furnace, the heat treatment machining effect is better, the clamping unit can clamp the steel with the concave structure for quenching, and the steel is subjected to descaling treatment after quenching is finished.

Description

technical field [0001] The invention relates to the field of heat treatment processing equipment, in particular to a heating and quenching device for steel with a concave structure. Background technique [0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. Annealing, normalizing, quenching, and tempering are the "four fires" in the overall heat treatment. Among them, quenching and tempering are closely related, and they are often used together, and both are indispensable. Quenching is to preheat the steel to a certain temperature and then rapidly cool it in quenching media such as water, oil or other inorganic salts and organic aqueous solutions. After quenching, the steel part becomes hard, but at the same time it becomes brittle. In order to eliminate the brittleness in time, it generally needs to be tempered in time. In order to reduce the ...
