Device for quenching of elongated steel wire

Abstract

The invention discloses a device for quenching of an elongated steel wire. The device comprises a quenching furnace. A heating chamber is arranged in the quenching furnace. At least one cooling oil groove is arranged at the bottom of the heating chamber along a length direction of the quenching furnace. The device also comprises a transport mechanism for transporting a steel wire into the heating chamber. The transport mechanism comprises a transport dolly and a support plate. The support plate and the transport dolly are connected by a turnover mechanism. After a steel wire placed on the support plate is heated, the turnover mechanism rotates the support plate so that the steel wire is dumped into the cooling oil groove. The device for quenching of an elongated steel wire has both functions of heating and cooling and is suitable specially for quenching and cooling of a elongated steel wire.

Description

technical field [0001] The invention relates to metal heat treatment equipment, in particular to a long and thin steel wire quenching device. Background technique [0002] Metal screens are widely used in metallurgy, mining, medicine, chemical industry, construction and other fields, and metal woven screens are the most commonly used form of screens. Many of the existing metal woven screens are woven by ordinary carbon steel wires. The screens made of cold-drawn high-quality steel wires have a hardness between HRC22-28, low surface hardness, poor wear resistance, and short service life. . This kind of screen needs to be replaced frequently, which not only increases the use cost, but also affects the production efficiency. There is also a cold-drawn steel wire with the highest hardness between HRC36-42, which is generally used to wind the spring, because the spring has a large bending radius and is not easy to break; Breakage occurs, which destroys the metallographic struc...

AI Technical Summary

Problems solved by technology

With the increasing application of metal screens, thin and dense metal screens are more and more commonly used, and the steel wires used to produce such metal screens are relatively thin, with a diameter of about 0.5mm-12mm. In order to save steel wires The raw materials generally use 15m long steel wires to weave multiple screens, but it takes too long for such thin and long steel wires to be taken out from the current quenching furnace and poured into the cooling oil tank after being heated, and the heating effect on the steel wires is lost.

Therefore, the current quenching cooling system cannot be applied to thin and long metal mesh wires
