A steel wire rod heat treatment device

Abstract

The invention relates to the technical field of steel wire rod heat treatment equipment, in particular to a steel wire rod heat treatment device, which includes a second sleeve, a number of heating blocks are fixedly connected to the inner wall of the second sleeve, and a side plate is fixedly connected to one end of the second sleeve , the outer side of the second sleeve is covered with the first sleeve, and the inner side of one end of the first sleeve is fixedly connected with a sealing plate, and the bottom end of the second sleeve is fixedly connected with a plurality of first support blocks, and the first support blocks are far away from the first support block. One end of the second sleeve is in contact with the inner side of the first sleeve, and the same side of the first sleeve and the second sleeve is fixedly connected with a return-shaped block, and the inner side of the second sleeve is fixedly connected with a plurality of second support blocks. The two support blocks are rotatably connected with rollers, a placement plate is placed on the top of the rollers, an end cover is inserted inside the end of the second sleeve away from the side plate, a rolling mechanism is installed at the bottom of the end cover, and a temperature sensor is installed on one side of the side plate . The invention has a simple structure, can reduce the natural aging time of the steel wire rod, and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of steel wire rod heat treatment equipment, in particular to a steel wire rod heat treatment device. Background technique [0002] Wire rod is also called wire rod, which usually refers to small-diameter round steel in a coil. The diameter of the wire rod is in the range of 5-19 mm (usually 6-9 mm), and its lower limit is the minimum size of the hot-rolled steel section. Stressed steel wire has the characteristics of high tensile strength and yield strength, good plasticity, and low relaxation performance. It is widely used in the construction of cement products, bridges, nuclear power plants, high-rise long-span buildings, expressways, etc. 82B wire rod is used to produce high-strength prestressed steel wire. The raw material, its production and use has attracted more and more attention. There will be residual internal stress in the wire rod (such as 82B wire rod) just after rolling, and the hydrogen elemen...

[0002] Wire rod is also called wire rod, which usually refers to small-diameter round steel in a coil. The diameter of the wire rod is in the range of 5-19 mm (usually 6-9 mm), and its lower limit is the minimum size of the hot-rolled steel section. Stressed steel wire has the characteristics of high tensile strength and yield strength, good plasticity, and low relaxation performance. It is widely used in the construction of cement products, bridges, nuclear power plants, high-rise long-span buildings, expressways, etc. 82B wire rod is used to produce high-strength prestressed steel wire. The raw material, its production and use has attracted more and more attention. There will be residual internal stress in the wire rod (such as 82B wire rod) just after rolling, and the hydrogen element in the steel has not escaped and diffused in time, and the reduction of area is low. If If it is drawn immediately, there will be broken wires, so it needs to be stored in the natural environment for a certain period of time to eliminate the internal stress, let the hydrogen element diffuse and escape, and the reduction of area will increase, and then draw again, but in mass production In the middle, because the products occupy the storage area and the inventory pressure is high, the production often needs to be stopped immediately after the first batch. The production of the next batch of wire rods can only be organized after the mechanical properties of the previous batch of wire rods pass the natural aging test and leave the factory. Both management and production have brought certain difficulties, and at the same time will occupy the working capital of the enterprise
