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.).HIGH SPEED CIRCULAR SAWING MACHINE HY-100NC 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.HIGH SPEED CIRCULAR SAWING MACHINE HY-120NC 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. Six details of gas carburizing 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.Control of retained austenite in tooth angle by vacuum carburizing heat treatment
