Understand the heat t πδreatment process friends under$‍®≤stand the annealing furnace, anneal←$$★ing furnace is widely used in cε≠hemical plants, crude≥π¶♥ oil, foodstuffs, metallurgical iΩ÷ndustry, machinery and →§φequipment, light industry, pow ≥er engineering, ships, pap​<er industry, mining, pharmaceutical indεβ∑ustry, centralised heating and other γ≤≈•industries, such as ↔♦∏∞heating, cooling, cold ±↑suspected, volatility and  ×other technological processesλ€∏÷ of operation.

Principle of annealing furnace:　　

According to the fan circulation sy×₩​stem so that the annea"γ↓ling furnace temperature inside the fu™§Ωrnace chamber all over♦™™ the proportion, annealing furnace 2→<∑ furnace chamber room can©& be operated separately, enh<★ ★ance the annealing of ‌' high efficiency, each furnace cha★↕₩mber is two fans, but there is no g€★as filtration system, there is a ∏¥¶♥discrepancy with the actual±φ♦< situation. According to €αthe fan circulation system to make th★ εe temperature in the furnace spα"₩read evenly, according to the♠→λ heat treatment process to recombine t•€γ£he plastic film raw material macr ≤™©o-construction, to enhance >×the reliability and conver♥≤​sion of high-efficiency. The§© casting parts are heate‍δ≈☆d to 950 ℃ up and do>>​©wn, insulated and kept warm for a ¥ εcertain period of time and then c↓≠©₩ooled moderately, wh¶✘♣©ich is used to remove the ther↔> mal stress of steel casting pa₽&γrts and welding parts. For stee​$l products heated gradual¥∏♦↑ly produce martensite tempδ¥≠erature of the following 100 to≠​ 200 ℃, insulation and heat preserv<"βation after cooling in the air←"≠, you can remove therλε★§mal stress.

A method of heat treatme™ ←∑nt of metallic materials in which the λ<material is heated slowly to a cert∞↓ain temperature, held for a § ₩∑good length of time,λδ  and then cooled at a sui★εtable rate (usually slowly, soφ ☆₹metimes manoeuvrably). The> ε purpose is to make th♠≈γ‍e raw material or product work↔✔↓∑piece produced by casting, for≤↔♦ging, welding or drilling s$≠often, improve plast​‌☆icity and ductility, m​"↑ake the composition of↑× the homogeneous, remove t‌&★he residual stress, or to obtain th ✘e desired mechanical properties. Anne€↑aling process with the purpo¥♥&✔se of the different and t¶↕here are a variety of d•✔∑→ifferent processes, such∞✘§ as recrystallisation a↕£nnealing, isothermal p ε↔rocess annealing, homogenis←÷ation annealing, grey caβ↔©st iron annealing, rem$¶★ove internal stress aγ★nnealing, plastic deformation ann↔€→ealing, and its anti-aging a →↓nnealing, electromagnetic field €"¥≈annealing these.

1、Improve or exclude steel in casting,×₩∞ casting, cold rolling and welding w•←elding operations in th→∞¶e process of various types of instituti≤¶onal shortcomings and their residual st♠"" ress, to avoid product workpiece def♥↓ormation, cracking.

2, soften the produc& ↔βt workpiece to facilit ✘↕•ate turning production and p₽≠rocessing.

3、Optimise the crystal and imp≈​rove the mechanism to enhance δ↔the physical properti≈ ∏​es of the castings.

4, for the final heat treat∑ ₹ment process (heat treatmen×★¶‍t, quenching) to do a gooσ≈d job of the mechanism of advance prepaγ©δration.
