Πώς να διακρίνετε την ποιότητα του φούρνου σιγαστήρα;

For users, a high-quality muffle furnace can improve production efficiency and extend service life. So, how to distinguish the quality of equipment?

1. A high-quality high-temperature electric furnace generally has a microcomputer control system, which can be programmed to operate, and one-key heating and cooling. The heating rate can also be adjusted by yourself. The temperature control must also be precise, which requires good quality components. There is also dual-circuit protection, with protections such as overshoot, overshoot, undershoot, segment couple, phase loss, overvoltage, overcurrent, overtemperature, current feedback, and soft start. In order to prevent the components from being burned when these situations occur, the electric furnace cannot be used continuously.

2. The other thing is to look at the refractory materials in the furnace. Generally, high-temperature electric furnaces of good quality are made of vacuum-formed high-purity alumina poly-light materials. The materials are easy to touch and the loading positions (furnace mouth, furnace bottom) are light-weight. Hollow spherical alumina board, the advantages of these two kinds of refractory are high temperature, low heat storage, resistance to rapid heat and cold, no cracks, no slagging, and good insulation performance. The use of these two materials can increase the energy-saving effect of electric furnaces by more than half.

3. A high-quality high-temperature electric furnace also has a good insulation effect. This requires the use of good insulation materials, and the furnace lining has three layers of insulation materials, which are aluminum silicate fiberboard, alumina fiberboard, and alumina (polycrystalline) fiberboard. . Using these materials as thermal insulation materials, the thermal insulation effect is good, naturally more energy-saving.

The above is the main content of how to distinguish the quality of the muffle furnace.
