The annealing furnace is mainly used for the annealing of large carbon steel and alloy steel parts. You must not know this knowledge, so do you want to know the introduction of stainless steel annealing furnace? Let us and Kehua Induction Heating Equipment learn about these introductions. . Stainless steel annealing furnace 1, annealing furnace heat treatment furnace is divided into annealing furnace, quenching furnace, tempering furnace, normalizing furnace, quenching and tempering furnace, mainly used for annealing of large carbon steel and alloy steel parts; tempering of surface quenched parts; stress relief of weldments Annealing, aging and other heat treatment processes. Heating methods include electric heating, fuel oil, gas, coal-fired, and hot air circulation. Annealing furnace is a new type of heat exchange equipment. The annealing furnace is an energy-saving periodic operation furnace with a super energy-saving structure and a fiber structure, which saves 60% of electricity. 2. Structure The skeleton of the annealing furnace is welded by various types of steel, the outer frame is made of channel steel as the main beam, the coaming plate is made of cold sheet, the trolley annealing furnace is made of channel steel as the main beam, and the bottom plate and the front and rear plates are medium plates. Annealing furnace transmission part: The trolley transmission adopts a motor and a reducer to drive a set of driving wheels at the front end through a chain. The furnace door drive adopts the combination of worm gear reducer and electric motor to lift electrically. Sealing: The trolley and the furnace body are sealed with a labyrinth structure, and there are automatic sand sealing knife sealing devices on both sides of the trolley. The furnace door is sealed by rolling channel pressing and spring pressing automatic mechanism. The furnace body part adopts high-quality refractory brick structure to ensure the tightness of the furnace. The pressure-resistant part of the trolley is built with high-alumina bricks, and thermal insulation bricks are added to the lower part. Annealing furnace combustion system: several burners are installed on both sides of the oil furnace, and the heat flow reciprocates in the furnace to ensure the uniformity of furnace temperature. Automatic and semi-automatic types can be selected as required. Smoke exhaust preheating device: a smoke exhaust preheating device is installed at the rear and upper end of the furnace. When the flue gas in the furnace passes through the preheater, it is sent to the cold air by the fan for preheating, and then sent to the burner by the pipeline for combustion support. A manual butterfly valve is installed at the outlet, which can adjust the pressure in the furnace. It is widely used in heating, cooling, condensation, evaporation and other processes in chemical, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, papermaking, mining, medicine, central heating and other industrial sectors. 3. Classification trolley type RT3 series trolley type resistance furnace is a national standard energy-saving periodic operation furnace, super energy-saving structure, using fiber structure, saving 30% of electricity. The exclusive production adopts composite high-alumina porcelain nail group, trolley anti-collision sealing brick, automatic sealing trolley and furnace door, integrated rail, no basic installation, and can be used on the level ground. Mainly used for high chromium, high manganese steel castings, ductile iron, rolls, steel balls, 45 steel, stainless steel and other quenching, annealing, aging and heat treatment of various mechanical parts. Product features: 1. No noise and no environmental pollution. 2. Small heat storage, less heat loss. 3. High temperature control accuracy and strong furnace temperature uniformity. 4. High degree of automation and simple operation. 5. It can be set by PID programming and run automatically. 6. Good sealing, long life, safe and reliable. Widely used in chemical, petroleum, food, metallurgy, machinery, light industry, electric power, shipbuilding, papermaking, mining, medicine, central heating and other industrial sectors. With the development of social productivity, its application in various industries is more and more extensive.
