Problems solved by technology

[0003] For example, the Chinese patent with the notification number CN2811317Y discloses an intermediate frequency quenching and tempering heat treatment equipment for long rod workpieces. It consists of sensors arranged concentrically and installed on a bracket. The bracket is installed on two gantry frames, and there is a lifting mechanism for the bracket between the gantry frames. The transmission device is composed of multiple rotating rollers. Through a set of sensors It can meet the requirements of different power for quenching and tempering, but because both loading and unloading need to be done manually, it will lead to the problem of low work efficiency

Abstract

The invention discloses a heat treatment production line for bars, and a treatment technology thereof, and aims to solve the problem of low heat treatment production efficiency of traditional bars. According to the key points of the technical scheme, the heat treatment production line for the bars comprises a quenching and tempering rack as well as a feeding mechanism arranged on one side of the quenching and tempering rack, a conveyor arranged on the quenching and tempering rack, a quenching and tempering mechanism arranged on the quenching and tempering rack along the conveyor, and a discharging mechanism arranged on one side of the quenching and tempering rack; the feeding mechanism comprises a feeding rack used for arranging steel bars, and the quenching and tempering mechanism comprises a quenching mechanism, a cooling mechanism and a tempering mechanism which are arranged on the quenching and tempering rack in the conveyor direction; and the discharging mechanism comprises a discharging rack arranged on one side of the quenching and tempering rack. According to the heat treatment production line for the bars, through a complete production line structure, not only the heat treatment efficiency of the bars is improved, but also the deformation of the bars in the heat treatment process can be reduced effectively; and the qualification rate of the bars is improved.

Description

technical field [0001] The invention relates to the field of heat treatment equipment, more specifically, it relates to a heat treatment production line for bars and a treatment process thereof. Background technique [0002] With the rapid development of the construction industry, the market demand for long rod parts such as steel bars is also increasing. The hot-rolled steel bars are quenched and tempered at high temperature to improve the performance of the steel bars. Existing steel bar quenching and tempering heat treatment equipment usually uses coils to perform high-temperature quenching, cooling, and tempering processes on steel bars, and the mechanical properties of steel bars after quenching and tempering treatment are optimized and improved. [0003] For example, the Chinese patent with the notification number CN2811317Y discloses an intermediate frequency quenching and tempering heat treatment equipment for long rod workpieces. It consists of sensors arranged con...
