Gas-shield water-based quenching device

Abstract

The invention relates to a gas-shield water-based quenching device comprising a first water-based quenching tank, wherein a second water-based quenching tank is arranged on one end of the first water-based quenching tank; a first gas-shield box is arranged between the first water-based quenching tank and the second water-based quenching tank; a second gas-shield box is arranged on the other end of the second water-based quenching tank; corresponding quenching tanks are arranged in the first water-based quenching tank and the second water-based quenching tank; water-based quenching liquid is arranged into the quenching tanks; when a steel wire passes through the first water-based quenching tank and the second water-based quenching tank, the water-based quenching liquid respectively quenches the steel wire to avoid environmental pollution and damage to human bodies in the process of quenching by utilizing a lead pan; inert gas is charged into the first gas-shield box and the second gas-shield box to avoid the oxidation of the steel wire; and the length of the corresponding quenching tank in the first water-based quenching tank can be regulated by utilizing the movement of a guide plate relevant to an overflow plate. Thus the invention changes the mechanical strength of the steel wire, reduces processing cost and has the advantages of energy saving, environmental protection, safety and reliability.

Description

technical field [0001] The invention relates to a water-based quenching device, in particular to a gas-protected water-based quenching device, in particular to a quenching device for heat-treating steel wires of steel cords. Background technique [0002] At present, the domestic electroplating production line, pretreatment production line and other steel wire quenching generally adopt the way of lead pot quenching. The lead pot quenching of the electroplating production line and the pretreatment production line has the following problems: 1. When the lead pot is heated to 600°C, the steel wire is quenched; while the steel wire is quenched, the vapor of lead volatilizes into the atmosphere, which is harmful to human health and the environment. Cause pollution and damage; 2, in the quenching process, along with the steam volatilization of lead, can affect the service life of lead pot, also cause production cost higher.
