Understand the heat treatment process ₹•$≠friends understand the annealing f★↓ ¥urnace, annealing furnace is widely Ω∏used in chemical plants, cru×<γ&de oil, foodstuffs, metallur≈§gical industry, machiα™nery and equipment, light industry, p↔©γ↔ower engineering, ships, paper industry♣✘•, mining, pharmaceutical indu✘"stry, centralised heating and ←←₹other industries, such as heating, coo£÷ling, cold suspected, vo₽>↕•latility and other technolog‌λλical processes of operatiγ≤ ←on.

Principle of annealing furnace:　　

According to the fan circulatio‍β≥​n system so that the annealing furnace ÷∞€ temperature inside the furnace chambe Ωφr all over the proportionσε÷∏, annealing furnace 2 f®π✔urnace chamber room can be operat₩λed separately, enhanπ→ce the annealing of high efficiency, ea✔λch furnace chamber is two fans, bu♠>♣t there is no gas filtration sy↔≠✔↔stem, there is a discrepancy with the ©>©actual situation. Accordi ±ng to the fan circulation sys'₹tem to make the temper ↓λature in the furnace spread eve↓₹¶'nly, according to the heat ≥ ☆treatment process to re₩λcombine the plastic film raw§★¶ material macro-construction, to eφ♥±nhance the reliability and¥∞★ conversion of high-efficien​✔✘cy. The casting parts are heated to 950∞≠ ℃ up and down, insu∑γ★‍lated and kept warm for ↕‍a certain period of time and then coole₽‍≠©d moderately, which is u↕♠sed to remove the thermal stress of &♥↑steel casting parts and welding par☆​≈ts. For steel products heated gradua★↓✘lly produce martensite temper→♠ature of the following 100 to 200&♣ ℃, insulation and he &®at preservation after cooling in th↓★€←e air, you can remove thermal st↕∏®ress.

A method of heat treatment of meta"•llic materials in which the mεδ₹aterial is heated sl→™♦δowly to a certain temperature, held ♠₩₽for a good length of time, and then§≠Ω cooled at a suitable rate (usually sl$&owly, sometimes manoeuvrab∞≈φ♣ly). The purpose is to make the raw mε←♦÷aterial or product workpεσ<λiece produced by casting, fπ®γ•orging, welding or drilling softe€•n, improve plasticity and ducti≥≥lity, make the composition of' ₩® the homogeneous, remove ✘✘the residual stress, or to obtain₽♠ the desired mechanical propert₹↓σ§ies. Annealing process with the p •"urpose of the different and≥→↔£ there are a variety of diff÷&erent processes, such as recr∑±★ystallisation annealing, isoth♣★ermal process annealing, homεδγogenisation annealing, grey cast☆≈₩φ iron annealing, remove internal stress★§< annealing, plastic deform₽ ≥ ation annealing, and its ♠">σanti-aging annealing, el↑£≤‌ectromagnetic field annealing these←"λ.

Annealing furnace role　　

1、Improve or exclude steel i↕→<♣n casting, casting, cold rolling a₽←εnd welding welding operations in the p₹•¶σrocess of various types of instituti←♦β∏onal shortcomings and their residua≠ §l stress, to avoid product wor ♠±kpiece deformation, cracki‌∑ng.

2, soften the product workpiece to fac‌₩ilitate turning production and proce✔÷ssing.

3、Optimise the crystal and improve the≈ε​ mechanism to enhance ✔β£the physical properties of the casting∞αs.

4, for the final heat treatment proces£σ≠₩s (heat treatment, quench∏≈✘∏ing) to do a good job of ★​✘the mechanism of adv¥∑&↑ance preparation.
