Problems solved by technology
[0008] The purpose of the present invention is to solve the problem that existing heat treatment furnaces in the prior art are difficult to meet the requirements of temperature uniformity, accuracy, and process adjustment flexibility, and samples cannot be taken out during the process, so that the simulated data is far from meeting the requirements of the process. The shortcomings of the test requirements provide a thermal simulation furnace with a controllable heating / cooling structure and midway sampling. The thermal simulation furnace can be equipped with a computer for numerical simulation production, and the heating rate can be accurately controlled. The speed adjustment range is large, and samples can be taken for testing at various stages. The large sample size does not affect the temperature field in the furnace, the temperature uniformity in the furnace is good, and the surface and internal temperature of the workpiece can be monitored during heating and cooling.
