Gas industrial furnace is a complex thermal equipment. It generally consists of the following parts: furnace, gas combustion device, flue gas exhaust device, furnace door and lifting device, metal frame, various auxiliary equipment (such as waste heat utilization device, various measurement control and adjustment devices, etc.).VERTICAL CROSS CUTTING PULLEY TYPE METAL BAND SAW MACHINE The furnace is the core area of the gas industrial furnace. It is a place where the gas can be stably burned, and the heated workpiece can directly or indirectly exchange heat with the high-temperature flame and flue gas.VERTICAL METAL BAND SAWING MACHINE The hearth is made of refractory materials and is a closed space surrounded by furnace walls, furnace roof and furnace bottom (including foundation).The side brickwork of the furnace is called the furnace wall. Separate heat pipe radiator vacuum brazing It is required to have sufficiently high refractoriness and qualified heat insulation performance. The interior of the furnace wall is built with refractory clay bricks, plus a heat insulating layer, and the outer surface is covered with a steel plate shell with a thickness of 4 to 10 mm.Causes and Control of Deformation in Metal Vacuum Heat Treatment
