What is the function of the annealing furnace? What is the operation and principle? -Kehua
With the continuous development of society and the development of the industrial economy, the annealing furnace is an indispensable machine for many industries, especially the forging industry. So do you know what the function of the annealing furnace is? What is the operation and principle? You go into detail. Annealing Furnace An annealing furnace is a process used in semiconductor device fabrication that involves heating multiple semiconductor wafers to affect their electrical properties. Heat treatments are designed for different effects. The wafer can be heated to activate dopants, convert thin films to thin films or convert thin films to wafer substrate interfaces, densify deposited thin films, change the state of growing thin films, repair implanted damage, move dopants or transfer dopants The agent is transferred from one film to another or from the film into the wafer substrate. The annealing furnace can be integrated into other furnace processing steps, such as oxidation, or can be processed by itself. The annealing furnace is completed by equipment specially designed for heating semiconductor wafers. 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. Annealing furnace function The operation and principle of the annealing furnace The annealing furnace skeleton is formed by welding various types of steel. The outer frame uses channel steel as the main beam, the coaming plate uses cold sheet, and the trolley annealing furnace uses channel steel as the main beam, the bottom plate and the front and rear. The function end plate of the resistance furnace adopts the middle plate. The transmission part of the annealing furnace: The trolley transmission adopts a motor and a reducer, and then drives a set of driving wheels at the front end through the chain. The furnace door drive adopts a worm gear reducer and a combination of electric motors to lift and lower. 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 to seal the part of the furnace body using high-quality refractory brick structure. 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: Many 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 upper end of the furnace. When the flue gas in the furnace passes through the preheater, the cold air is sent by the fan for preheating, and then sent to the burner by the pipeline for combustion support. , and install a manual butterfly valve 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. Annealing furnace function 1. Improve or eliminate various structural defects and residual stress caused by steel in the process of casting, rolling, forging and welding, and avoid deformation and cracking of the workpiece. Annealing furnace function 2. Prepare the structure for the final heat treatment (quenching, tempering). 3. Refine the grains and improve the structure to improve the mechanical properties of the workpiece. 4. Soften the workpiece to facilitate cutting. The above is a detailed introduction to the annealing furnace. After reading it, you must have a certain understanding of the annealing furnace, as well as the function and operation of the annealing furnace. Do you have any idea to buy it? Here I recommend Kehua, Kehua is a very good choice for its high quality and low price.
