Quality management of fused magnesia brick:
1. Central kiln firing quality problems
According to the national standard sintered clay brick, burrs, placed brick, brick, brittle, spiral pattern brick, beyond the tolerance size, no complete surface, impurity bulge, missing edge edge appearance quality excessive, all as unqualified products. From the actual situation of some ceramic enterprises, a lot of unqualified deburring and floor tiles accounted for the largest, usually 1% -3% of annual output, some villages and towns of enterprises up to 5%. So in the firing process, to ensure product quality is the key, at the same time, reduce product cost is also the key to improving the economic efficiency of enterprises.(http://www.magnesiabricks.com/product/fused_magnesia_brick.html)
2. Adobe quality and quality of the furnace on the firing quality
Wet adobe into the kiln, one is to improve the furnace water vapor content, increase coal consumption. The second is the water vapor can be around the body, broken blank billet stability, resulting in a series of damage. The use of enterprise drying is not only caused by the kiln collapse and waste, but also caused the production process of "blocking."
3. Starting from the kiln and code quality, improve the combustion quality
Adobe dry quality is to ensure that the adobe is in good condition (no cracks, moisture, cold, etc.), dehydration balance and short drying cycle, two factors, one is the internal additive as a diluent right to reduce dry sensitivity. The second is to strengthen the management of the drying process, natural drying should pay special attention to the following: 1. Drying facilities (frame, machine row, groove repair). 2. Protective facilities (bags, curtains, etc.). 3. To establish the perfect operation of flower, nursing and management discipline. 4. To fulfill the responsibility to limit the drying cycle and the rejection rate, supported by rewards and penalties. Artificial drying in the optimization of thermal parameters and scientific management on the basis of ensuring the stability of the entire system and balance the effect of drying and quality of the implementation.
