Reducing the forging furnace consumption is of great significance, and the commonly used measures are:
1, the use of reasonable heat source
The commonly used fuels for forging heating are solid, powder, liquid, gas and so on. The solid combustion is coal; The powder fuel is pulverized coal; Liquid fuel is heavy oil, light diesel; Gas fuels are natural gas, liquefied petroleum gas and gas. Most manufacturers use natural gas, some commonly use liquefied petroleum gas, gas, some manufacturers also use heavy oil, light diesel.
2, the use of advanced heating furnace type
Digital regenerative high speed pulse combustion and control technology and continuous fuel regenerative pulse combustion and control technology are adopted in the gas heating furnace for blanks and forgings. In contrast, the combustion mode of conventional high-speed burner + air preheater is applied to the high temperature forging furnace, the energy saving rate is as high as 50%, and the furnace temperature uniformity is controlled between ±10℃. In the medium and low temperature heat treatment furnace, the energy saving rate is up to 30-50%, and the furnace temperature uniformity is controlled between ±5℃.
3, the use of hot material furnace loading process
Hot charging furnace is an effective energy-saving measure for heating large forgings, that is, the steel ingot poured from the steelmaking workshop is directly transported to the forging workshop for heating without cooling, and the temperature of the furnace is generally controlled above 600℃. Compared with cold feeding furnace, can save 40-45% energy, at the same time can save heating time, reduce the number of heating configuration, improve production efficiency.
4. Waste heat recovery technology
The exhaust gas temperature in the fuel furnace is as high as 600-1200℃, and the heat taken away accounts for 30-70% of the total heat. The recovery and utilization of this part of heat is an important way to save energy in the forging workshop. At present, the main utilization method is to use preheater, that is, to use flue gas waste heat to heat the combustion air and gas fuel. As the country vigorously promotes energy conservation and emission reduction, the application of waste heat secondary recovery and utilization technology in forging industry will be more and more extensive.
