Tail end quenching experiment device

Abstract

The invention discloses a heat treatment experiment device and belongs to the field of material heat treatment and performance tests. The heat treatment experiment device mainly comprises a plurality of heating furnaces, a rotary mechanism, a quenching workbench, a normalization workbench, a tail end quenching workbench, a furnace body support rotary mechanism, a furnace body, a circulating cooling system and an atmosphere protection system. The rotary mechanism supports the heating furnaces and drives the heating furnaces to rotate along a spindle. Under driving of the spindle, the furnace body can rotate to be above the set workbench, meanwhile, under driving of the furnace body rotary mechanism, the furnace body can rotate by 90 degrees, and the process that samples from the insides of the heating furnaces are subjected to oil quenching, water quenching, normalization and tail end quenching is completed. Traditional manual operation is replaced, and thus danger and measuring errors caused by manual operation are avoided completely. Artificial intelligence software is installed on an upper computer connected to the heat treatment experiment device, estimation judgment and experiment result prediction can be conducted on the set experiment parameters, the local operation process can be simulated through a virtual laboratory, and thus misoperation in the operation process is reduced. The heat treatment experiment device has wide experiment teaching application prospects and further has the characteristics of simple operation, high efficiency, safety, water saving and the like at the same time.

Description

technical field [0001] The invention relates to a heat treatment experiment heating device, which belongs to the field of material heat treatment and performance testing. Background technique [0002] Metal heat treatment is one of the important processes in the mechanical manufacturing process. The quality of heat treatment directly determines the product quality and performance of the workpiece. Therefore, the experimental teaching of heat treatment process is one of the compulsory courses for students of materials and machinery. Material heat treatment is divided into different processes according to different processes: normalizing treatment, annealing treatment, quenching, solution heat treatment, aging and other treatment methods. The treatment process requires heating and heat preservation of the sample. For a long time, heat treatment experiments in colleges and universities have been Using a box-type furnace or a crucible furnace to heat the sample has problems such...

[0003] The end quenching method to determine the hardenability of steel is also called the end quenching method. This method was proposed by Jominy et al. in 1938, so it is often called the Jominy end quenching method abroad. Because this method is simple and reliable, it is used as a standard hardenability test in many countries. However, the experimental method has been using the manual quenching mode after the furnace body is heated, and the speed of operation directly affects the test accuracy. Therefore, reduce and keep constant. The operation time after the sample is released is of great significance to improve the test accuracy and ensure the product quality
