Vacuum heat treatment equipment frit furnace is a furnace for processing frit with high melting point

The frit furnace is mainly used for the preparation of frit, glass low-temperature flux, enamel glaze and binder in the laboratory of ceramics, glass, enamel and other industries. It can also be used as production equipment for small enterprises.

First of all, the frit is to mix more than a dozen chemical raw materials in a certain proportion and put them into the frit furnace at more than 1000 degrees to make glass liquid, and then flow from the furnace to the pool to purify the broken glass block solid, and then put it in the frit furnace. Add water to the ball mill and grind it into a slurry liquid, and then pour it on the embryo body of the floor tile or wall tile. Floor).

The so-called frit furnace is a kiln for processing frit with a high melting point. The general temperature is around 1100. There used to be coal-fired ones. Now, some places have strict environmental protection measures, and they all use gas generators to burn.

Vacuum heat treatment equipment avoids reducing furnace temperature

The fuel must be fully contacted and mixed with enough air in the combustion. When the furnace temperature is high enough, the combustion reaction speed of the muffle furnace is very fast, the oxygen in the air will be quickly consumed, and enough air must be supplied. In actual operation, the air sent into the furnace is excess, but the air The excess amount should not be too much and should be appropriate to avoid lowering the furnace temperature.

Combustible substances or fine coal chips are volatilized from the fuel, and the flue gas flows while burning. If the furnace space (volume) is too small, the flue gas flows too fast, and the flue gas stays in the furnace for too short a time. Combustibles and coal dust are fully burnt. In particular, when combustibles (combustible gas, oil droplets) touch the heating surface of the boiler before they are completely burned, the combustibles are cooled below the ignition temperature and cannot be completely burned, forming carbon nodules. At the same time, ensure enough combustion space in the muffle furnace, which is conducive to full contact and mixing of air and combustibles, so that combustibles can be fully burned.
