The tube furnace has simple structure, high thermal efficiency, continuous production, and convenient operation. Therefore, it has a wide range of applications in metallurgy, glass, heat treatment, new energy and other industries. In order to better use, pay attention to the use of specifications, as follows Based on the experience of the relevant staff, we have summarized a few issues that are easy to be overlooked during use. Let's take a look at it together:
1. First, when using a tube furnace to heat the workpiece, do not add any pre-burned plates:
2. All heated workpieces, including the container containing the workpieces, should be placed on the burner plate and heated. Try to avoid placing the ceramic fiberboard directly on the bottom of the furnace, otherwise it will cause uneven stress on the fiberboard or excessive temperature and damage the bottom of the furnace.
3. Secondly, the tube furnace is cooled quickly and the furnace door is opened at high temperature:
Because the ceramic fiber has a good heat insulation effect, the energy consumption in the heat insulation process is very low, and the temperature drops slowly after a power failure. Some customers hope that the next experiment can be performed immediately after completing one experiment, so the furnace door can be opened at high temperature to obtain a higher cooling rate. However, the damage of the tube furnace is very large, and it is easy to make the furnace cold and hot. Cracked, the heating element cannot withstand this thermal shock. We usually recommend that you open the furnace door carefully when it cools to at least 600°C. If you really need high-temperature pick-and-place parts, please consider whether you can use a silicon carbide furnace.
4. Do not bake after being closed for a long time:
This is also a detail that is easy to overlook. Basically, when using an oven, all customers can make an oven, but many customers forget the oven when they use the oven again after the machine has been shut down for more than a week. The ceramic fiber board has a large number of fine holes. If it cannot be used for a long time, it may absorb water vapor and other magazines, so the oven can effectively remove the water vapor in the holes as needed.
The above listed several problems that are easy to overlook in the use of tube furnaces. In order to use them better, you must keep these points in mind to avoid bad consequences caused by improper operations in future operations. In addition, the equipment should be overhauled and maintained regularly, and problems should be corrected in time to make the equipment run more efficiently and effectively for a long time.
