The metal aluminum processed from industrial aluminum profiles is excellent in both quality and characteristics, which is inseparable from the quality characteristics of industrial aluminum profiles! Industrial aluminum profile raw materials are often so excellent. The key is that its own production process is very complicated. Major industrial aluminum profile manufacturers need to solve the raw materials of industrial aluminum profiles according to the calorific value caused by fuel combustion in forging heating furnace, aluminum rod heating furnace and embrittlement furnace. It is not difficult to see that the consumption of this kind of fuel will account for about 70% of the total energy consumption, How complicated is the processing technology of industrial aluminum profile! Just because of this, major aluminum alloy profile companies have implemented energy-saving projects to reduce fuel consumption.
The technical key of environmental protection and energy saving combustion of industrial aluminum profile company includes the following points:
(1) High temperature gas combustion technology of forging heating furnace. According to the application of flue gas circulation or immediate spray combustion in fuel furnace, high temperature gas combustion is different from traditional combustion. The basic principle is that the combustion gas is heated above 1000 ℃ according to the porcelain honeycomb regenerator, introduced into the furnace at an appropriate rate, and fully mixed with the combustion materials in the furnace under the effect of rapid cyclone mixing, so as to reduce the CO2 in the air. It is diluted, burned in the liquid with oxygen deficient components, and burned under the high-temperature gas standard to complete the combustion of low gas fuel, so as to reduce the air oxidation burn out of aluminum. The specific discharge rate of the mixture at the inlet and outlet of the burner is about 60m / s, the flame diameter is about 0.5-0.7m, and the length is about 2.5-3M. There are two burners in the furnace for phase change and actual operation. The powder layer is often exchanged, and the ultra-low temperature zone cannot be generated to ensure the uniform temperature in the furnace.
(2) Automatic combustion control system. The purpose is to complete the automatic identification and process management of main parameters such as total flow, temperature and working pressure of combustion machinery and equipment, so as to improve the utilization rate of electric energy and reduce the cost of equipment maintenance and management. The common automatic control system of forging furnace includes furnace pressure automatic control system and combustion system software automatic control system.
