The drying electric furnace controls the heating speed not too fast

For ordinary, put the vessel filled with liquid on the asbestos mesh and heat it with a gas lamp (or box-type resistance furnace). It is suitable for solutions or pure liquids that are easily synthesized or volatile and extinguished above 100 °C. Generally, those with average heating between 100-400 ℃ should be heated with sand bath. And the heating sample of liquid, according to the thermal stability of the liquid, direct heating, water bath heating and sand bath heating and evaporation can be adopted respectively. In order to speed up the evaporation rate, in addition to properly increasing the temperature, it is also necessary to expand the evaporation area. Evaporating vessels are commonly used evaporating dishes. When the evaporation is stopped, the amount of liquid left in the evaporating dish should not exceed 2/3 of its total capacity, the heating should be average, and the heating speed should not be controlled too fast.

Selection method of industrial electric furnace for dryer

1. It is necessary to look at the heat treatment process requirements and technical requirements of the processed product parts, so that you can choose which kind of electric furnace you need;

2. Look at the outer shape, size, weight and material of the processed parts;

3. Auxiliary materials and energy supply required for heat treatment;

The basic characteristics of the drying cabinet type electric furnace: natural air insulation type, light and easy to handle; fast heating speed, it only takes about 30 minutes to heat up to 1100 °C; the furnace is heated by radiation on both sides, and the temperature is evenly distributed; temperature control: PID automatic control LED digital display; heat preservation: imported high temperature resistant ceramic cotton heat preservation and ceramic plate, high aluminum cotton triple heat preservation; heater: Swedish imported KANTHAL heater, durable, stable temperature rise, fast heating speed; internal use of high temperature resistant ceramic plate, not easy to deform, The exterior is made of galvanized and high-temperature baking paint, which is beautiful and not easy to fall off the paint.
