Crucible heating device and method

Abstract

The invention relates to a crucible heating device and method. The crucible heating method comprises the following steps of 1, arranging the crucible heating device; 2, putting materials to be evaporated into a crucible; 3, setting heating power of different subsections of a heating wire into initial heating power; 4, evaporating the materials and monitoring liquid level of the materials in the crucible through a measurement unit; 5, regulating the heating power of different subsections of the heating wire until the materials are evaporated to the required degree according to the liquid level of the materials. The invention further provides the crucible heating device. By means of the crucible heating device and method, the material filling amount of the crucible is enlarged, cavity opening times are reduced, and the utilization rate of a cabinet is increased.

Description

technical field [0001] The invention relates to a crucible heating device and method, which has an improved temperature control function. Background technique [0002] The crucible is a vessel or melting tank made of extremely refractory materials (such as clay, graphite, china clay, quartz or relatively difficult-melt metal iron, etc.). The crucible is usually a bowl-shaped container with a deep ceramic bottom. When there is a solid that needs to be heated with a high fire, a crucible must be used. Because it can withstand high temperatures better than glassware. When using the crucible, the crucible cover is usually placed obliquely on the crucible to prevent the heated object from jumping out, and to allow air to freely enter and exit for possible oxidation reactions. Because the bottom of the crucible is very small, it generally needs to be placed on a mud triangle to be directly heated by fire. The crucible can be placed upright or obliquely on the iron tripod, and ...

AI Technical Summary

Problems solved by technology

[0006] As mentioned above, there are following defects in the prior art: the relevant heating equipment and method temperature control devices in the prior art are relatively simple, and the temperature control method is also relatively simple, which can only roughly adjust the temperature in the crucible as a whole, and the crucible Uneven internal heat transfer and the resulting uneven temperature cannot be solved
