Understand the heat treatment proceΩ★&‍ss friends understand "♦the annealing furnace, annealing fu÷↑φ<rnace is widely used in ch≥$emical plants, crude oil, φ×foodstuffs, metallurgical in≈≥♦dustry, machinery and equipment, ligh€≠φ☆t industry, power enginee€εring, ships, paper indus∑£↑try, mining, pharmaceutical indust♣§ry, centralised heating anα<d other industries, such as ♣δ♠heating, cooling, cold suspe₩λ←cted, volatility and"× other technological procβ∞εesses of operation.

Principle of annealing furnγδace:　　

According to the fan cir ↑¥ culation system so that the annealing ✘✘furnace temperature •¥Ωπinside the furnace chamber ♦∑¶all over the proportion, anneal★€ing furnace 2 furnace chambe€α↓¶r room can be operated separately,"γ enhance the annealing of high efδ±ficiency, each furnace cham<•ber is two fans, but there is nδ≥o gas filtration system, ♦σδ there is a discrepancy →≠€with the actual situation.±∏÷  According to the fan circulation ↕™system to make the temperature i∞→n the furnace spread×™₩ evenly, according to the heat tr∑✘∑₩eatment process to recombine t€♥♦he plastic film raw material m•♠acro-construction, to enhanc♣≥∑e the reliability and conversion of hi☆"₽→gh-efficiency. The casting parts a₹π¶re heated to 950 ℃ up and down, ins λ↓ulated and kept warm for a certain✔• period of time and then cooled moderat₩€αely, which is used to remove the<←• thermal stress of steel casti★∑÷ng parts and welding parts. For steel≤÷♣↔ products heated gradually produce ma≤πrtensite temperature of ✘₹the following 100 to 200 ≠©£←℃, insulation and heat pres∏£σervation after cooling> ‍≤ in the air, you can remove thermal δ♠★ stress.

A method of heat treatment of metallic®$✔ materials in which the materi≠←↑al is heated slowly to a c>≥∞ertain temperature, held for a good len₽¶gth of time, and then φ♣σcooled at a suitable ‌₩rate (usually slowly, som±₹etimes manoeuvrably). The pur•φ≠>pose is to make the raw materia✘€l or product workpiece produceβγd by casting, forging, we‌Ω↑≤lding or drilling soften, improve ☆'plasticity and ductility, make  ↑the composition of the h ×omogeneous, remove the r&®£βesidual stress, or to obtain Ω©the desired mechanical pr‌✔operties. Annealing p♥$rocess with the purpos≤☆↑e of the different and ther®‍e are a variety of diff☆φσ§erent processes, suchεγ§→ as recrystallisation annealing∞↔↓, isothermal process annealing, homoε↕ genisation annealing, grey cast iron a☆♥εnnealing, remove internal stress annea$←ling, plastic deformat±$ion annealing, and its an ±• ti-aging annealing, ∏φelectromagnetic field annealing t"♣ hese.

Annealing furnace role　　

1、Improve or exclude steel ∏♦in casting, casting, cold rolling and☆Ω welding welding operations∏÷ in the process of var£§ious types of instituγ₽tional shortcomings and the∑↕✔ir residual stress, to avo ±α♥id product workpiece>β☆ deformation, cracking.

2, soften the product work↔€∑piece to facilitate turning producti₽Ωon and processing.

3、Optimise the crystal and improve t₩&he mechanism to enhance the physi∑•♣cal properties of the castings.

4, for the final heat treatment proces≥×s (heat treatment, quenching) to ↓•≥do a good job of the m‌±echanism of advance prepa✔''σration.
