Ring rotary hearth flexible heat treatment production line and heat treatment method thereof

Abstract

The invention discloses a ring rotary hearth flexible heat treatment production line and a heat treatment method of the ring rotary hearth flexible heat treatment production line. The ring rotary hearth flexible heat treatment production line comprises a feeding table. The upper end and the lower end of the feeding table are correspondingly and symmetrically provided with a feeding material storage platform and conveying device and a discharging material storage platform and conveying device. A two-station front cleaning machine is arranged on the top of the feeding material storage platform and conveying device. A three-station rear cleaning machine is arranged at the bottom of a double-station oil quenching tank and lifting device. The left side of the three-station rear cleaning machine is connected with a push-rod type low-temperature tempering furnace through a pawl type push-pull chain mechanism, a discharging transition platform is connected to the left side of an air cooling station, and a lifting platform is mounted on the left side of the discharging transition platform. By the adoption of the ring rotary hearth flexible heat treatment production line and the heat treatment method, a variety of products with different depths can be produced at the same time, and the ring rotary hearth flexible heat treatment production line has the very flexible production characteristic; very convenient conditions are provided for organization production; and empty disc push is not needed for process replacement during process shift, and the equipment efficiency is played to the maximum.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to an annular rotary bottom flexible heat treatment production line and a heat treatment method thereof. Background technique [0002] Heat treatment refers to a metal thermal processing process in which materials are heated, kept warm and cooled in a solid state to obtain the desired structure and properties. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the surface of the workpiece. , to give or improve the performance of the workpiece. It is characterized by improving the intrinsic quality of the workpiece, which is generally not visible to the naked eye. In order to make metal workpieces have the requ...
