A Heat Treatment Furnace for Rapid Heating

Abstract

The invention discloses a heat treatment furnace for rapid temperature rise, which comprises a furnace chamber, a positioning piece for fixing a sample in the furnace chamber, a heat source for heating the sample, and a heat source driving component and a positioning piece driving component; the heat source is a heating Two heating plates arranged facing each other, the heat source driving part is used to drive the two heating plates to clamp the sample or keep away from each other, and the radiation area is between the two heating plates; the positioning part driving part is used to drive the positioning part to make The sample enters and exits the radiation area; the present invention uses two heating plates to conduct double-sided synchronous contact heating on the sample, utilizes the small heat capacity and high thermal conductivity of the thin strip sample, and realizes ultra-high heating and cooling speed and precise control of heat treatment time through direct contact , and the cooling speed can be adjusted according to the needs, with fast heating and cooling speed, convenient operation, high temperature and time control accuracy, suitable for heat treatment of thin strips, films and powder samples with high thermal conductivity and small heat capacity.

Description

technical field [0001] The invention relates to the technical field of heat treatment, in particular to a heat treatment furnace for rapid temperature rise. Background technique [0002] Heat treatment is to heat the material to a certain temperature, keep it warm for a certain period of time, and then cool it down to room temperature or even lower at a certain speed, so as to achieve the purpose of improving the structure and physical and chemical properties of the material. Heat treatment has a very popular application in the heat treatment of various materials such as metals, ceramics, and glass. The heat treatment process of materials can have an important impact on the defects, stress, structure, and morphology of materials, and is the most commonly used process in material research and processing. [0003] With the advancement of heat treatment technology, the definition of heat treatment has expanded, the parameters that need to be controlled in the heat treatment pr...

AI Technical Summary

Problems solved by technology

However, the area of ​​laser heat treatment is limited by the size of the laser beam. The scanning plane method can realize large-area heat treatment, but the efficiency is low and the cost is high.

Both induction current and energized Joule heating also have problems such as serious temperature overshoot and low temperature control accuracy, and their applicability is limited.

[0006] For heat treatment with high heating and cooling speed and high temperature control precision, the above equipment can no longer meet the requirements. It is very necessary to develop a heat treatment device with more convenient operation and more precise temperature and time control.
