Isothermal quenching system and quenching process based on metal heat treatment

Abstract

The invention discloses an isothermal quenching system and quenching process based on metal heat treatment. The isothermal quenching system comprises a shell, wherein a crucible is fixedly connected to the interior of the shell, a heating electrode is fixedly connected to the bottom of the inner wall of the crucible, and a bottom plate is fixedly connected to the bottom of the shell. According to the isothermal quenching system and quenching process, a metal blank is supported by a filtering disc through a supporting disc and a metal slender rod, then an electric cylinder drives a protection mechanism to protect the crucible through a base plate and a transmission box, and finally the transmission mechanism drives salt solution and fixing plates to rotate through a rotating rod and stirring blades, so that the temperature uniformity of the salt solution is improved; and meanwhile, the metal blank can make effective contact with the salt solution, so that the quneching system has the advantages of supporting and precipitation prevention, and solves the problems that because an existing isothermal quenching system does not have a certain supporting and precipitation prevention function, cannot stir the salt solution and cannot support and push the metal blank simultaneously, the metal blank cannot fully contact with the salt solution, and the processing efficiency is low.

Description

technical field [0001] The invention relates to the technical field of austempering, in particular to an austempering system and a quenching process for metal heat treatment. Background technique [0002] Austempering refers to the quenching method that after the workpiece is quenched and heated, if it is kept at the temperature of the lower bainite transformation zone for a long time, it can complete the isothermal transformation of austenite and obtain the lower bainite structure. [0003] During the heat treatment process of some metals, the isothermal quenching system will be used for isothermal quenching, but the existing isothermal quenching system does not have a certain support and anti-sedimentation function, cannot stir the salt solution, and cannot support and push the metal blank, resulting in The metal blank cannot be fully contacted with the salt solution, and the processing efficiency is low. Contents of the invention [0004] In order to solve the problems...
