Understand the heat treatment processε₽ friends understand the annealing ♠£♦furnace, annealing furnace is widel®↓•∞y used in chemical plants, crude×↓₩ oil, foodstuffs, me®αtallurgical industry, machine€≥πry and equipment, light ind©™ustry, power engineering, ships, pβ<↔aper industry, mining, pharmaceutica€ ‌l industry, centralised γ'₽¶heating and other industr↕™πies, such as heating, cooling, cold sus<"♣®pected, volatility a∑→≈nd other technological processes of ♠≥φ∑operation.

Principle of annealing furnace:　"πλ☆　

According to the fan circulation s★₹≤ystem so that the annealing furnac♥$δe temperature inside the furnace cham♥αβ↑ber all over the proportion, annealing↕α© furnace 2 furnace chamber room ca✔$n be operated separately, enhance "™γ§the annealing of high efficiency, each ​​furnace chamber is two fans, bu>>t there is no gas filtration system, tφ↕•↔here is a discrepancy  ★£with the actual situat® ion. According to the fan circulat₹>"πion system to make tΩ∑→he temperature in the furnace spread eαקvenly, according to the heat t←λφ reatment process to r ¶®×ecombine the plastic fi←♦Ω★lm raw material macro-construct "ion, to enhance the reliability and con✘$version of high-efficiency. The casting∑δ parts are heated to 950 ℃ up aπδφ‍nd down, insulated and kept war₹÷m for a certain period of time and thφ✘↕en cooled moderately, which is ©♥→used to remove the t¶§☆÷hermal stress of steel casting parts ✘≤ and welding parts. For steel products h×← eated gradually produce martensi★€±te temperature of the followin©₩πg 100 to 200 ℃, insulati∑$on and heat preservation after cooling™♠β✘ in the air, you can remove thermaφ₹₹l stress.

A method of heat treatment o ♠♦₹f metallic materials in w☆& hich the material is heated slowl≈¶y to a certain temper™ πλature, held for a good length o£σ÷f time, and then cooled at a suita≈♥∑≤ble rate (usually slowly, sometimes ma®↔noeuvrably). The purpose is to make tπΩπhe raw material or pro★α≠duct workpiece produced by castingβ↔, forging, welding or drilling soften,¶∏±φ improve plasticity and d®≤↓∑uctility, make the composition of the h×↕β♣omogeneous, remove the resi ​$dual stress, or to obtain t↔ α↓he desired mechanical prop≤♦σ>erties. Annealing process with the pu¥π​rpose of the different and t£‍here are a variety of di¶±fferent processes, such as reελcrystallisation annealing, isotherma÷↔l process annealing, homoge∏δ↑∞nisation annealing, greyλ™∏™ cast iron annealing, remove internal $£¶stress annealing, plas•★tic deformation anneε≈aling, and its anti-aging annealing↑∏, electromagnetic field annealing thesε£₹≠e.

Annealing furnace role　　

1、Improve or exclude✔π← steel in casting, casting, c↓>old rolling and welding weldinα₩→αg operations in the prδ¥ocess of various types of instit​✔$∑utional shortcomings an±πε≤d their residual stre→™≈ ss, to avoid product workpi∞'ece deformation, crack £♠ing.

2, soften the product work→'→™piece to facilitate turning production λδ∑ and processing.

3、Optimise the crystal and improφ​&ve the mechanism to enhance the phyε≈ ♠sical properties of the castings.

4, for the final heat treatme≥αλ→nt process (heat treatment, quenching)&≥× to do a good job of th✘♥λ↕e mechanism of advance pre↓™✘★paration.
