Laser source high-temperature heat treatment device and heat treatment method

Abstract

The invention discloses a laser source high-temperature heat treatment device and a heat treatment method. The laser source high-temperature heat treatment device comprises a control system, a laser transmitter and a metal cavity, the laser emitter is connected with a plurality of laser irradiation heads in parallel, a hemispherical fixing seat on which N laser irradiation heads are uniformly distributed is arranged above the metal cavity, and an irradiation head is also arranged on the side surface of the metal cavity. A fixed rod is arranged in the metal box, a movable platform controlled by an adjusting button is arranged on the fixed rod, and an object to be heated is placed on the movable platform. According to the property of an object and the degree needing to be heated, the positions and the number of the laser irradiation heads participating in work are selected on the control system, the adjusting button controls the moving platform to ascend so that the object to be heated can be close to the laser irradiation heads in work and rotate, and the object is evenly heated. In this way, the problems that a traditional heating furnace is uneven in heating, slow in temperature rise, too large in working space and not ideal in heating effect on transparent objects are solved, and the laser high-temperature heat treatment effect is improved under the condition that safe heating is guaranteed.

Description

technical field [0001] The invention relates to the technical field of laser heating, in particular to a laser source high-temperature heat treatment device and a heat treatment method. Background technique [0002] With the rapid development of industry, aerospace, metal smelting, laboratory research and development, etc. have higher and higher requirements for heating technology. Heat treatment technology has made breakthroughs and developments in recent years, and has experienced the transformation from traditional electric heating to microwave energy heating and the combination of the two heating methods. [0003] Traditional electric heating furnaces are divided into two types: ordinary heat transfer heating furnaces, metal or alloy wire heating furnaces. Its heating principle is heat conduction, convection and radiation, during which there is a temperature gradient, which makes the heated element heated unevenly and local overheating occurs; at the same time, it takes...
