Understand the heat treatα₩ment process friends u±↕Ωnderstand the annealλ→×ing furnace, annealing​≠ furnace is widely use$•d in chemical plants, cr©₹ude oil, foodstuffs, metallurgical i'αε≈ndustry, machinery and eqΩ←♥ uipment, light indus✘∞γtry, power engineering, ships, paper i♥ ¥ndustry, mining, pharma±π∑ceutical industry, centralised hea©>≥$ting and other industries, such as≤←¶ heating, cooling, cold s≈ε←≥uspected, volatility and o≠↑ther technological proce×$←®sses of operation.

Principle of annealing furnac₽​♥♠e:　　

According to the fan ∞×☆​circulation system so that the anneali♠∏↔ng furnace temperature inside t÷δ↓he furnace chamber all ove€♠≈r the proportion, anγ☆ nealing furnace 2 furnace chambε er room can be operated separately, e"♥nhance the annealing of high effi♥✔® ciency, each furnace chamber is twσ✔↓<o fans, but there is no gas filtrγ©'Ωation system, there is a discrep>"ancy with the actual s≤β↓λituation. According to the fan c↕₹≥≈irculation system to make the tempe↔÷‌®rature in the furnace sp ε©read evenly, according to the heat tr☆₹↕eatment process to rec↑>ombine the plastic film raw material mᶥacro-construction, to enhan♠ "ce the reliability and ≈¶conversion of high-efficiency. The ca±→∑≥sting parts are heated to 950 ℃ up Ω£γand down, insulated and kept warγ₽m for a certain period of time and the↓γ≠n cooled moderately, which is u ≈sed to remove the ther∞‍₩§mal stress of steel casting par₩₹<∞ts and welding parts. For≠®​ steel products heated gradual€±β ly produce martensite temperature of€±≥ the following 100 to 200 ℃, i←γnsulation and heat preservation ≈↓♦≤after cooling in the air, you can removε☆ πe thermal stress.

A method of heat treatment of metalli™•↑ c materials in which✘'₹ the material is heated slowly to δ"β"a certain temperature, heλ‍♣ld for a good length of tiσ®me, and then cooled at a suitable "∑≤rate (usually slowly, sometime©↔↔s manoeuvrably). The purp★λ∏ose is to make the raw mateΩ®♠ rial or product workpiece produced ♦α↑σby casting, forging,★€™ welding or drilling soften≠÷$, improve plasticity and d✔‌↑uctility, make the co₽α£mposition of the homogeneous, r☆ emove the residual stress, or✔Ω♦→ to obtain the desire✔↔₹↓d mechanical properties. Annealing •&process with the purpose of™< the different and there are ↑ a variety of different processe≥∑♦‍s, such as recrystallisa≈↔Ω tion annealing, isothermal pr≠Ω ocess annealing, homogenisat ☆♥$ion annealing, grey cα♥ast iron annealing, remov✘σe internal stress annea  $ling, plastic deforma✔∏×tion annealing, and its anti-ag©÷ing annealing, electromagnetic field aγφ​nnealing these.

Annealing furnace role　　

1、Improve or exclude steel in cβ↑asting, casting, cold rolli€‌‌ng and welding welding operations in t→φ↔∑he process of various ty•λδpes of institutional shortcominδ¥gs and their residual stress, to avo←$id product workpiece de×πformation, cracking.

2, soften the product workpiece to fa→≤→cilitate turning production and process•∑‌ing.

3、Optimise the crystal and improve t π£he mechanism to enhance t↓≠<he physical properties of t‍£πhe castings.

4, for the final heat treatment proce®'ss (heat treatment, quenching≈♥'♠) to do a good job of the mechanis •∏&m of advance preparation.
