Energy saving measures of heating furnace

Energy saving measures of heating furnace Heating furnaces, various industrial furnaces, and boilers are all high-energy-consuming kilns that consume a lot of resources. When the heating furnace heats the ingot, the temperature is high, and the flue gas takes away a large amount of high-temperature heat, resulting in wasted waste and low heat utilization rate. Measures to save energy and reduce consumption include:Vacuum heat treatment of aerospace materials 1. Paint RLHY-2 black body radiation energy-saving paint on the inner wall of the heating furnace, increase the radiation rate of the refractory material of the heating furnace wall, and speed up the radiation heat transfer in the furnace. This product can achieve an energy saving rate of 10%~20%.Martensitic stainless steel quenching vacuum heat treatment process 2. The high emissivity barrel-shaped device is installed on the inner wall of the heating furnace, which also plays the role of improving the emissivity of the refractory material of the furnace wall, accelerating the radiation heat transfer in the furnace, and the energy saving rate of the product is 3%~6%. The disadvantage of this method is that The investment is too large and the cost recovery period is relatively long.Vacuum Heat Treatment of Hollow Linear Optical Axis 3. The use of honeycomb ceramic regenerator can achieve the purpose of waste heat recovery, but the one-time investment is large, there are many switching mechanisms, and the maintenance cost is high; cause serious energy loss. The use of heat exchangers can make up for the shortcomings of honeycomb ceramics, and has less investment, no switching mechanism, and no maintenance.Precision gear vacuum heat treatment
