The firing of enamel products is a very important part of the enamel process. During the firing process, the various firing technical parameters and operating points that the operators of the enamel factory must strictly follow, and strictly follow the reasonable process production and implementation, is conducive to improving the enamel production. product quality. So how to judge the time and firing effect of enamel products?

The firing temperature of enamel products is set with a furnace temperature gauge, and the firing time is controlled by a stopwatch. After the firing, relevant instruments and equipment are used to detect the gloss or adhesion strength of enamel products to judge the firing quality of enamel products.

If it is fired in a batch muffle furnace, it can generally be judged by visual inspection. Put the dry powder blank into the furnace, under the contrast of the bright red furnace wall, the powder blank shows a dark color, and when the temperature rises, it will turn into a light and color similar to the furnace wall, indicating that the temperature of the blank at this time is the same as the furnace wall. The temperature is close, but the internal temperature of the iron billet may not have reached it, and it will take a while to be fired. As for how long it takes to burn, it depends on the experience of the operator, which is related to the wall thickness and material of the enamel billet.

If it is a continuous firing furnace, it is adjusted by setting the furnace temperature table and the linear speed of the transmission chain (or the speed of the driving wheel), and the temperature and speed are the product's adhesion, porcelain surface gloss and smoothness by the on-site technical supervisor. The casting adjustment is determined after multiple inspections such as the degree and so on.
