模具鋼深冷處理工藝是怎樣的？深冷處理的作用性非常大，近期有很多客戶來咨詢模具鋼深冷處理工藝，模具鋼深冷處理溫度等等之類的問題，天成模具小編在這里為大家詳細(xì)解答下，模具鋼深冷處理工藝是怎樣的。模具鋼深冷處理一般在零下196℃進(jìn)行。DC53模具鋼板材深冷正常的處理工藝如下：一般在淬火和回火工序之間進(jìn)行，也能在淬火回火之后進(jìn)行深冷處理。但是有一種情況要注意，如果在淬火、回火后鋼中仍保留有殘余奧氏體，則在深冷處理后仍需要再進(jìn)行一次回火。深冷處理能提高鋼的耐磨性和抗回火穩(wěn)定性。深冷處理不僅用于冷作模具，也可用于熱作模具和硬質(zhì)合金。

src="https://tyunfile.71360.com/UploadFile/wxtdmj/637438965201868005/5793540.png"></div><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼基本特性：(4)良好的耐磨性能，由于熱作模具制作時(shí)除受到毛坯變形時(shí)產(chǎn)生摩擦磨損之外，還受到高溫氧化腐蝕和氧化鐵屑的研磨，所以需要熱作模具鋼有較高的硬度和抗黏附性。 </p> <p> (5)良好的導(dǎo)熱性。為了使模具不致積熱過多，導(dǎo)致力學(xué)性能下降，要盡可能降低模面溫度，減小模具內(nèi)部的溫差，這就要求熱作模具鋼要有良好的導(dǎo)熱件能。 </p> <p> (6)良好的成形加工工藝性能，以滿足加工成形的需要。 </p> <p> (7)高淬透性。熱作模具鋼一般尺寸比較大，熱鍛模尤其是這樣，為了使整個(gè)模具截面的力學(xué)性能均勻，這就要求熱作模具鋼有高的淬透性能。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 熱作模具鋼在服役條件下除了承受載荷的周期性變化之外，還受到高溫及周期性的急冷急熱的作用，因此，評(píng)價(jià)熱作模具鋼的斷裂抗力應(yīng)重視材料的熱機(jī)械疲勞斷裂性能。熱機(jī)械疲勞是一種綜合性能的指標(biāo)，它包括熱疲勞性能、機(jī)械疲勞裂紋擴(kuò)展速率和斷裂韌性三個(gè)方面。 </p> <p> 熱疲勞性能反映材料在熱疲勞裂紋萌生之前的工作壽命，抗熱疲勞性能高的材料，萌生熱疲勞裂紋的熱循環(huán)次數(shù)較多；機(jī)械疲勞裂紋擴(kuò)展速率反映材料在熱疲勞裂紋萌生之后，在鍛壓力的作用下裂紋向內(nèi)部擴(kuò)展時(shí)，每一應(yīng)力循環(huán)的擴(kuò)展量；斷裂韌性反映材料對(duì)已存在的裂紋發(fā)生失穩(wěn)擴(kuò)展的抗力。斷裂韌性高的材料，其中的裂紋如要發(fā)生失穩(wěn)擴(kuò)展，必須在裂紋前端具有足夠高的應(yīng)力強(qiáng)度因子，也就是必須有較大的裂紋長度。在應(yīng)力恒定的前提下，在一種模具中已經(jīng)存在一條疲勞裂紋，如果模具材料的斷裂韌性值較高，則裂紋必須擴(kuò)展得更深，才能發(fā)生失穩(wěn)擴(kuò)展。 </p> <p> 也就是說，抗熱疲勞性能決定了疲勞裂紋萌生前的那部分壽命；而裂紋擴(kuò)展速率和斷裂韌性，可以決定當(dāng)裂紋萌生后發(fā)生亞臨界擴(kuò)展的那部分壽命。因此，熱作模具如要獲得高的壽命，模具材料應(yīng)具備高的抗熱疲勞性能、低的裂紋擴(kuò)展速率和高的斷裂韌性值。 </p> <p> <br /> </p> <p> <br />

偏析即鋼的成分與組織不均勻性的表現(xiàn)，這是在模具鋼的低倍組織的檢驗(yàn)中常存在的一種缺陷。是鋼錠在凝固過程中形成的，與鋼的化學(xué)成分和澆注溫度等有關(guān)。一般分為樹枝狀的偏析、方形偏析、點(diǎn)狀偏析等。由于樹枝狀的偏析的存在，使負(fù)然各個(gè)不同的方向的力學(xué)性能表現(xiàn)出明顯的差異。方形偏析是由于鑄錠結(jié)晶時(shí)，在柱狀晶的末端與錠心等軸晶區(qū)間，聚集了較多的雜質(zhì)和孔隙而形成的。嚴(yán)重的方形偏析，對(duì)鋼材的質(zhì)量的影響是顯著的，特別是切削加工量很大的零件或心部受力的模具零件。偏析除了影響模具鋼力學(xué)性能的等向性外，對(duì)模具的拋光性能也有一定的影響。因此，國外相關(guān)的標(biāo)準(zhǔn)中有嚴(yán)格的規(guī)定。

模具鋼是用來制造冷沖模、熱鍛模、壓鑄模等模具的鋼種。模具是機(jī)械制造、無線電儀表、電機(jī)、電器等工業(yè)部門中制造零件的主要加工工具。模具的質(zhì)量直接影響著壓力加工工藝的質(zhì)量、產(chǎn)品的精度產(chǎn)量和生產(chǎn)成本，而模具的質(zhì)量與使用壽命除了靠合理的結(jié)構(gòu)設(shè)計(jì)和加工精度外，主要受模具材料和熱處理的影響。模具鋼大致可分為：冷軋模具鋼、熱軋模具鋼和塑料模具鋼三類，用于鍛造、沖壓、切型、壓鑄等。由于各種模具用途不同，工作條件復(fù)雜，因此對(duì)模具用鋼，按其所制造模具的工作條件，應(yīng)具有高的硬度、強(qiáng)度、耐磨性，足夠的韌性，以及高的淬透性、淬硬性和其他工藝性能。由于這類用途不同，工作條件復(fù)雜，因此對(duì)模具用鋼的性能要求也不同。
