Explain in detail the kiln operation yesterday when refining side, knot ring, refining kiln reason, since to find out why, we should study how to prevent and deal with. Refining and ring side is mainly due to high temperature, the resulting liquid volume, the operation can not keep up, caused by uneven ventilation, so the adjustment should be reasonable in production wind, coal, with the material, enhance operations, maintenance plus Less calcined material and ventilation balance between the kiln ventilation evenly, keeping light dark fire burning, stable end of the fire position, the feeding operation, on the side of the fire seems to cover non-covered, hidden when the flash point of Mars, there are often stable even a small amount of side wind rose, under normal operating conditions, often with Qianzai pry edge materials, reduce and eliminate high-temperature materials and lining brick refining knot, brick kiln firing if you have uneven surfaces, should be replaced, avoid hanging material. Results As refining is often associated with the kiln lining material between the bricks of a melt is formed, the structure of duplicity, surface is loose, while the inside is a relatively dense molten tacky whole drill rod can be inserted into the mixing junction pry away, when the depth of refining knot locations, places way off the kiln at the tumor roots exposed, clean thoroughly pry away from the destroyed, in order to avoid future trouble. And try to crack the tumor feeding the fire block paved surface with kiln, kiln surface lying areas or appropriated, to facilitate ventilation evenly. Smelting kiln process more difficult, we must first stop feeding, increase the blast (the material is cool), and then open a gap along the kiln wall, then gradually refining the junction portion pry down the refining process kiln, not only labor-intensive, and time long, as long as careful operation, refining the kiln can be prevented.
