Many users have a headache when they buy box type electric furnace products. They don't know which one to choose, so they are afraid to buy the ones with poor quality. If they buy the ones with poor quality carelessly, they will not spend money, which will affect their use. This kind of problem is very irritating, so what can be done to solve it? The answer is yes! The details are as follows.
When we buy box type electric furnace, we can judge the quality of the product from the following four aspects:
1. When we see the box type electric furnace, we first see its shell. So what kind of shell is of better quality? This depends on the material of the shell, because the service life of the box type electric furnace has a lot to do with the material of the shell. The electric furnace has not been used much. If the shell breaks first, it will not work. And the furnace is very high temperature, if it is very thin sheet iron is certainly not good, at least to use cold-rolled steel plate or carbon alloy steel plate, such a material can be strong and durable, there is to spray a layer of high temperature resistant coating on the shell in the furnace, and then build refractory brick, the shell also need to do baking paint and anti-corrosion process. This kind of electric furnace shell is of good quality.
2. Then it's about the insulation materials of the box type electric furnace. If you use the box type electric furnace, the common temperature is 1000 degrees, then the insulation materials of the box type electric furnace must be able to withstand high temperature up to 1100-1200 degrees. Similarly, the experimental furnace with the common temperature of 1600 ℃ needs to choose the insulation layer of 1700 degrees. Only in this way can you meet your use requirements, there will be no abnormal conditions, and ensure normal use In this case, the electric furnace can reach a long life. The thermal insulation material with good quality is fiber.
3. Moreover, it depends on the heating elements. The quality of the heating elements depends on the manufacturers. The products of the famous heating element manufacturers must be more reliable. If the temperature is 1800 ℃, the imported silicon molybdenum rod can be selected.
4. There are also electrical components, such as instruments, which also depend on the manufacturer, but there are also other manufacturers with better quality. Mainly depends on its accuracy, high accuracy, durable is good.
