Steel wire quenching process

Abstract

The invention belongs to the technical field of steel wire quenching, in particular to a steel wire quenching process. A quenching bin is arranged inside a quenching box; a cooling medium is filled into a cooling bin, and the bottom end of the cooling bin communicates with the quenching bin through a heating pipe; a condensing tank is arranged above the cooling bin and is filled with condensed gas; the inside of a pushing box is slidably provided with a sliding guide plate through a telescopic rod, and the sliding guide plate is provided with a hollow guiding rod; the end of the hollow guidingrod is slidably arranged in a guiding sliding hole, and the end of the hollow guiding rod is provided with a guiding push head; conveying rollers are evenly arranged on the outer wall of the quenching box through supporting frames; a conveying belt is arranged on the outer walls of the conveying rollers in a rotating manner, and the conveying belt is evenly connected with a plurality of elastic fastening bands through elastic connecting blocks; and steel wire segments can be shaken in the quenching box, so that the effect of changing the steel wire segments from the static state to the dynamic state in the quenching process is increased, and the quenching effect of the steel wire segments is further increased.

Description

technical field [0001] The invention belongs to the technical field of steel wire quenching, in particular to a steel wire quenching process. Background technique [0002] Steel wire is one of the four types of steel plate, tube, type and wire. It is a reprocessed product made of hot-rolled wire rod through cold drawing. In the production process of steel wire, in order to improve the mechanical properties of steel wire, steel wire is usually Hardening treatment is carried out to greatly improve the strength, hardness, wear resistance, fatigue strength and toughness of steel wire, so as to meet the different needs of various mechanical parts and tools. [0003] Steel wire occupies a very important position in the national economy, and steel wire quenching heat treatment is a very important process in the production process of steel wire. There are many methods of steel wire quenching and heat treatment, and the method of quenching in hot-melt lead with muffle furnace heatin...

Problems solved by technology

[0005] In order to make up for the deficiencies of the prior art, the present invention proposes a steel wire quenching process. The present invention is mainly used to solve the problem that the existing steel wire is usually in a static heating mode when it is quenched. This heating method is easy to make the inside and surface of the steel wire Inhomogeneous heating leads to large differences in the performance of the steel wire after quenching; and the cooling efficiency of the cooling medium is low when cooling the steel wire
