Energy consumption of forging production process including the kinetic energy of the fuel consumption and consumption.The fire burn up is the main energy consumption in the forging.Fuel consumption accounts for a large free forging workshop all kinds of more than 80% of the energy consumption.Reduce the forging furnace consumption is of great significance, the commonly used measures are:
1, adopt reasonable heat source
Forging heating common fuel such as solid, powder, liquid, gas type.The solid is burning coal;Fuel is coal powder;Liquid fuels is heavy oil, light diesel oil;Gas fuel is natural gas, liquefied petroleum gas, gas.
Most vendors using natural gas, and some common use liquefied petroleum gas, gas, also some vendors using heavy oil, light diesel oil.
2, the use of advanced heating furnace type
Casting, forging gas heating furnace using regenerative high-speed digital pulse combustion and control technology and the continuous supply of fuel regenerative pulse combustion and control technology.Compared with conventional high-speed burner + air preheater combustion mode, applied in the high temperature forging heating furnace, energy saving rate is as high as 50%, the uniformity of furnace temperature control between plus or minus 10 ℃, and applied in the medium and low temperature heat treatment furnace, energy saving rate of 30-50%, control the furnace temperature uniformity between + 5 ℃.
3, using hot furnace charging process
Hot furnace charging material is an effective energy saving measures of large forgings heating, that is, from steelmaking workshop ingot pouring completed without cooling is transported directly to the charging heating forging shop, general boiling temperature control in the above 600 ℃.Compared with the cold furnace charging material, energy-saving 40-45%, at the same time can save the heating time, reduce the amount of heating configuration, improve production efficiency.
4, waste heat recovery technology
To remove the fuel furnace flue gas temperature as high as 600-1200 ℃, take away the heat accounts for 30-70% of total calories, the recycle of the heat is the important way of energy saving forging shop.Methods is the main use of preheater, the use of flue gas waste heat of combustion air and gas fuel for heating.As the country to vigorously promote energy conservation and emissions reduction, secondary recovery of waste heat utilization technology application in the forging industry will be more and more widely.
