Wire rod conveying device for quenching tank

Abstract

The invention provides a wire rod conveying device for a quenching tank, relates to the technical field of salt bath heat treatment, and solves the problem that the conveying difficulty of wire rods is large when the wire rods are fed into or conveyed out of a salt bath tank. The device comprises a driving device and a plurality of cantilevered rollers, wherein the plurality of cantilevered rollers are in transmission connection with the driving device; the plurality of cantilevered rollers are symmetrically distributed on the two sides of the quenching tank in the length direction of the quenching tank; the bottom end of each of the cantilevered rollers is fixedly connected with a corresponding stepped pulley; the stepped pulleys are in a frustum cone shape; each row of stepped pulleys are formed into concave-shaped roller ways between an inlet of the quenching tank and an outlet of the quenching tank; a corresponding concave-shaped roller way comprises a downslope section, a horizontal section and an upslope section; the wire rods can be placed on the conical surfaces of the stepped pulleys; and when the cantilevered rollers are driven by the driving device to be rotated, the stepped pulleys are driven to be rotated, the wire rods can enter into the quenching tank from the downslope section along the two concave-shaped roller ways, are subjected to quenching treatment at thehorizontal section and then are conveyed out of the quenching tank through the upslope section, so that the wire rods can be easily fed into or conveyed out of the quenching tank.

Description

technical field [0001] The invention relates to the technical field of salt bath heat treatment, in particular to a wire rod conveying device for a quenching tank. Background technique [0002] Wire rod is the most important raw material for metal products, and has always been the focus of major steelware. Among them, wire rods with high attachment value such as bridge cables, springs, cords and other drawing series have been cooled by air-cooled Stelmo in the high-wire factory. In high-carbon steel or large-scale wire rods, it is difficult to solve abnormal structures such as low sorbite rate, carbon network in the center, and martensite in the center, resulting in fluctuations in product quality. Salt bath isothermal quenching can achieve the cooling effect of the lead bath. As an alternative to the air-cooled Stelmore process, it has great advantages in solving the uniformity of the wire structure and performance, but the way the wire rod enters and exits the salt bath h...
