According to the fan circulation system so that the annealing furnace temperature inside the furnace chamber all over the proportion, annealing furnace 2 furnace chamber room can be operated separately, enhance the annealing of high efficiency, each furnace chamber is two fans, but there is no gas filtration system, there is a discrepancy with the actual situation.
Understand the heat treatment process friends understand the annealing furnace, annealing furnace is widely used in chemical plants, crude oil, foodstuffs, metallurgical industry, machinery and equipment, light industry, power engineering, ships, paper industry, mining, pharmaceutical industry, centralised heating and other industries, such as heating, cooling, cold suspected, volatility and other technological processes of operation.
Principle of annealing furnace:
According to the fan circulation system so that the annealing furnace temperature inside the furnace chamber all over the proportion, annealing furnace 2 furnace chamber room can be operated separately, enhance the annealing of high efficiency, each furnace chamber is two fans, but there is no gas filtration system, there is a discrepancy with the actual situation. According to the fan circulation system to make the temperature in the furnace spread evenly, according to the heat treatment process to recombine the plastic film raw material macro-construction, to enhance the reliability and conversion of high-efficiency. The casting parts are heated to 950 ℃ up and down, insulated and kept warm for a certain period of time and then cooled moderately, which is used to remove the thermal stress of steel casting parts and welding parts. For steel products heated gradually produce martensite temperature of the following 100 to 200 ℃, insulation and heat preservation after cooling in the air, you can remove thermal stress.
A method of heat treatment of metallic materials in which the material is heated slowly to a certain temperature, held for a good length of time, and then cooled at a suitable rate (usually slowly, sometimes manoeuvrably). The purpose is to make the raw material or product workpiece produced by casting, forging, welding or drilling soften, improve plasticity and ductility, make the composition of the homogeneous, remove the residual stress, or to obtain the desired mechanical properties. Annealing process with the purpose of the different and there are a variety of different processes, such as recrystallisation annealing, isothermal process annealing, homogenisation annealing, grey cast iron annealing, remove internal stress annealing, plastic deformation annealing, and its anti-aging annealing, electromagnetic field annealing these.
Annealing furnace role
1、Improve or exclude steel in casting, casting, cold rolling and welding welding operations in the process of various types of institutional shortcomings and their residual stress, to avoid product workpiece deformation, cracking.
2, soften the product workpiece to facilitate turning production and processing.
3、Optimise the crystal and improve the mechanism to enhance the physical properties of the castings.
4, for the final heat treatment process (heat treatment, quenching) to do a good job of the mechanism of advance preparation.
