Embodiment Construction

[0014] The technical solution of the present invention is a heat treatment process for magnetic steel, which is characterized in that it comprises the following steps:

[0015] 1) Annealing the billet, put the casting into a 26KW high-temperature furnace, heat it up to 11000°C with the furnace, keep it warm for 1-2 hours, and cool the furnace;

[0016] 2) Product heat treatment: a) Medium temperature preheating: Arrange the coarsely ground products neatly, put them into stainless steel boxes in a high-temperature box furnace, and heat them to 850-9000°C for more than 30 minutes;

[0017] b) High-temperature solid solution: Send the preheated product to a high-temperature furnace at about 12400°C with a long stainless steel shovel, and keep it warm for 10-20 minutes. Special attention should be paid to controlling the temperature and holding time, as well as controlling the quantity of products loaded and loading coke into the furnace to create a reducing atmosphere;

Abstract

The invention discloses a magnetic steel heat treatment technology. The magnetic steel heat treatment technology comprises 1, casting blank annealing: putting a casting blank into a high temperature furnace at power of 26KW, carrying out furnace heating to a temperature of 11000 DEG C, carrying out thermal insulation for 1-2h and carrying out furnace cooling, and 2, product heat treatment: a, middle temperature preheating, b, high temperature solid solution, c, magnetic field air quenching or magnetic field air cooling, d, low temperature preheating: carrying out demagnetization on a product subjected to solid solution and air quenching, putting the product into a stainless steel small box, feeding the stainless steel small box with the product into a box-type resistance furnace, carrying out preheating at a temperature of 600-6500 DEG C and carrying out thermal insulation for greater than or equal to 20-30min, e, magnetic field isothermal treatment, f, multistage ageing and tempering and g, cooling to a temperature of about 2000 DEG C or less after tempering and then discharge. The magnetic steel heat treatment technology has simple processes, is free of repeated processes and improves work efficiency.

Description

technical field [0001] The invention relates to a heat treatment process for magnetic steel. Background technique [0002] The heat treatment process of magnet steel includes annealing of casting blanks and heat treatment of primary grinding products. The heat treatment of products consists of six stages: medium temperature preheating, high temperature solid solution, magnetic field cooling, low temperature preheating, magnetic field isothermal, and multi-stage failure. [0003] At present, the heat treatment process of magnet steel is relatively complicated, and there is no unified specification and standard, which causes the heat treatment process of magnet steel to be uneven, and many repeated processes also make the production efficiency low, increase the labor burden of workers, and make the product quality The market is not very competitive. For some operators who have just entered the industry, there is no clear method and process, resulting in frequent mistakes and ...
