Do you know the electric heating method of electric furnace - program box-type electric furnace

Today, Protech will explain the electric heating method of the programmed box-type electric furnace. In fact, it is also relatively simple in nature. You can basically understand it if you look at it carefully.
Electric heating method of programmed box-type electric furnace The essential characteristics of box-type electric furnace are: natural air heat-proof, light and easy to transport; The temperature rise is faster, and it only takes about 30 minutes to raise the temperature to 1100 ℃; The two sides of the furnace are electrically heated by radiation method, and the ambient temperature is evenly distributed; Temperature control system: PID automatic control system Led digital display; Thermal insulation: imported high-temperature resistant ceramic wool thermal insulation and ceramic fiber board, high aluminum wool triple thermal insulation; Heater: imported KANTHAL heater, durable, stable temperature rise, faster electric heating; High-temperature resistant ceramic fiber board is selected for the interior, which is not easy to deform, and galvanized and high-temperature baking paint is selected for the exterior, which is beautiful and generous, and is not easy to drop paint.
After reading the procedure, the electric heating method of the box-type electric furnace is also relatively simple.
Only after we master the basic method of electric heating of box-type electric furnace and the characteristics of the heating furnace can we better use it and play the role of the heating furnace. Because the furnace temperature is very important for the heating furnace.
We have to admit that the box-type resistance furnace is applicable to the solution or pure liquid medicine that can be synthesized under high ambient temperature. For ordinary use, put the utensils with liquid medicine on the asbestos net and use gas lamp (or box-type resistance furnace) to heat them electrically. It is applicable to the solution or pure solution that is easy to synthesize or volatilize and extinguish above 100 ℃. It is recommended to use electric heating in sand bath if the average temperature is between 100-400 ℃. As with the electric heating of the liquid medicine, according to the stability of the liquid medicine, direct electric heating, water bath heating and sand bath electric heating can be adopted for volatilization. In order to accelerate the volatilization rate, in addition to properly improving the ambient temperature, it is also necessary to expand the volatilization area. Evaporation vessels are commonly used for evaporation. When volatilization is stopped, the amount of liquid medicine left in the evaporating dish should not exceed 2/3 of its total capacity, the electric heating should be average, and the electric heating speed should not be too fast.
