Kiln
It is an equipment made of refractory materials for firing products. It is an essential facility in ceramic molding. With tens of thousands of years of ceramic firing history, mankind has accumulated rich kiln-making styles and experiences. From the open-pit burning on the ground and digging pits in primitive society to the steamed bun-shaped raised-flame round kiln, semi-inverted flame horseshoe-shaped kiln, half-slope dragon kiln, and duck-egg-shaped kiln, to today's indoor gas kilns and electric kilns, kiln technology In the process of continuous improvement and development.
Type
According to the types of calcined materials, it can be divided into ceramic kilns, cement kilns, glass kilns, enamel kilns, etc. The former can be divided into continuous kiln (tunnel kiln), semi-continuous kiln and intermittent kiln according to the operation method.
1. According to the heat source, it can be divided into flame kiln and electric heating kiln.
2. According to the condition of the heat source facing the green body, it can be divided into open flame kiln, muffled flame kiln and semi-muffled flame kiln.
3. According to the body carrier, it can be divided into kiln car kiln, push plate kiln, roller bottom kiln (roller kiln), conveyor belt kiln, walking beam kiln and air cushion kiln.
4. According to the number of channels, it can be divided into single-channel kiln, double-channel kiln and multi-channel kiln.
5. Generally, the fuel for large-scale kilns is mostly heavy oil, light diesel or coal gas and natural gas.
Wood kiln: Using firewood as fuel is the inheritance of the ancient kiln industry. Various kilns such as dragon kiln, steamed bun kiln, gourd kiln, etc. all belong to the category of firewood kiln. Because it requires wood for burning, it is not conducive to the protection of environmental resources. It is rarely seen except in some traditional ceramic production areas.
Coal kiln: It is an industrial kiln that uses coal as fuel. It was once widely used, but was later abandoned or improved to use gas, heavy oil, or light diesel as fuel due to high energy consumption and pollution.
Electric kiln: uses electricity as the energy source, mostly uses electric furnace wire, silicon carbon gang or molybdenum disilicide as the heating component, and relies on the principles of electric energy radiation and thermal conductivity for oxidizing atmosphere firing. Electronic program control, simple operation, good safety performance, suitable for various workplaces, Kung Fu Small Porcelain Electric Kiln is a must-have firing kiln for many ceramic studios.
Gas kiln: Using liquefied gas, coal gas or natural gas as fuel, it has strong firepower, low pollution, and is suitable for firing in different firing atmospheres. It is the most widely used kiln today.
