Understand the heat treatment proce≥ε€&ss friends understand the annΩβealing furnace, annealing furnace is♦•≤< widely used in chemical p≤€<​lants, crude oil, foodstuffs, metallu&↕≠rgical industry, machinery and↕β→π equipment, light industry, p→∑₹×ower engineering, ships, paper ind> •ustry, mining, pharmaceutical indus∞♥©try, centralised heating and other ind αustries, such as heating, c≈♣ooling, cold suspected, volatility and↓≤♥§ other technological pr ¶ocesses of operation.

Principle of annealing f×♠₩εurnace:　　

According to the fan circulation systemα✔ so that the annealing furnac≤₽e temperature inside ≠★±‍the furnace chamber all over ↔→π the proportion, annealing furnac"•≥₹e 2 furnace chamber •÷©φroom can be operated separately, enhan × <ce the annealing of high &∞"efficiency, each furnace cham$γ ber is two fans, but there is no gλ$as filtration system, there is "'♦a discrepancy with the actual ©®γsituation. According to ∏↑♥the fan circulation system to make <₽the temperature in the furnace s$ ©pread evenly, according to the heat ↔ ↓treatment process to recombine the ♠↔plastic film raw material macro-con₹←struction, to enhance γ↕ the reliability and convers$×ion of high-efficiency. The casting pa¥♥¶βrts are heated to 950 ℃ up and down,♥​ insulated and kept warm f ±φ™or a certain period of time β‌and then cooled moderately, which is u₹∏§♣sed to remove the thermal stres♠™☆♣s of steel casting parts and weldin↑π✔g parts. For steel products heate$™≈d gradually produce martensite temp"↑✔<erature of the following 100 to 200 ℃ε"∞, insulation and hea®≠δt preservation after cooling in the ¶§air, you can remove ther¥£ Ωmal stress.

A method of heat treγαatment of metallic materials×& in which the material is h≤'≥eated slowly to a certain temperatu¥✔₽re, held for a good length of time,≤$®Ω and then cooled at a suitab♥‍le rate (usually slowly, sometimes manα×<oeuvrably). The purpose ‌<¥§is to make the raw material or produ®®ct workpiece produced by®↑ casting, forging, welding ≈≠♠±or drilling soften, improve plasticity β¶and ductility, make the composition o​ f the homogeneous, remoγφve the residual stres$☆s, or to obtain the d≤‍esired mechanical properties. Annealin₽ ✘≥g process with the purpose→±× of the different and t&>☆™here are a variety of ©✘different processes, such as recr>£₹ ystallisation anneali±δng, isothermal process ↔≈•✘annealing, homogenisation anne£♠aling, grey cast iron annealing, rβ↑∑emove internal stress<₩ annealing, plastic deformation ann•±₩​ealing, and its anti-aging annealing, φ≤‍electromagnetic field ann ↕ealing these.

Annealing furnace role　　≈✔

1、Improve or exclude✔ε§ steel in casting, cas•₽ting, cold rolling and welding weldi <ng operations in the process of variouπ♦≥s types of institutional ​≈shortcomings and their residual s'↕∞₹tress, to avoid prod¥♦∞uct workpiece deformati¶"₩on, cracking.

2, soften the product worγ♥kpiece to facilitate©  turning production and p✘​↔rocessing.

3、Optimise the crystal an≥♣™d improve the mechanism to enhance∏α§ the physical proper‌↓✔ties of the castings.

4, for the final heat treatme← &"nt process (heat treatment, qu↑≥♥enching) to do a good job ofσ¶ the mechanism of adva¶‍∞σnce preparation.
