</p> <p> 由于熱作模具鋼工作條件的特點(diǎn)，因此會帶來以下方面的問題： </p> <p> （1）模腔表層金屬產(chǎn)生熱疲勞（龜裂）。熱作模具的工作特點(diǎn)是具有間歇性．每次使熱態(tài)金屬成形后都要用水、油、空氣等介質(zhì)冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復(fù)受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復(fù)的熱脹冷縮，即反復(fù)承受拉壓應(yīng)力作用．其結(jié)果引起模腔表面出現(xiàn)龜裂，稱為熱疲勞現(xiàn)象，由此，對熱模具鋼提出了第二個基本使用性能要求．即具有高的熱疲勞抗力。一般說來，影響鋼的熱疲勞抗力的因素主要有：①鋼的導(dǎo)熱性。鋼的導(dǎo)熱性高，可使模具表層金屬受熱程度降低，從而減小鋼的熱疲勞傾向性。一般認(rèn)為鋼的導(dǎo)熱性與合碳量有關(guān)，含碳量高時導(dǎo)熱性低，所以熱作模具鋼不宜采用高碳鋼，徐州模具鋼廠家，徐州模具鋼廠家。在生產(chǎn)中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會導(dǎo)致鋼的硬度和強(qiáng)度下降．也是不利的。②鋼的臨界點(diǎn)影響。通常鋼的臨界點(diǎn)（Acl）越高．鋼的熱疲勞傾向性越低。因此．一般通過加入合金元素Cr、W、Si、引來提高鋼的臨界點(diǎn)。從而提高鋼的熱疲勞抗，徐州模具鋼廠家。

熱作模具鋼在工作時承受著很大的沖擊力，模腔和高溫金屬接觸，反復(fù)地加熱和冷卻，其使用條件極其惡劣。為了滿足熱作模具的使用要求，熱作模具鋼應(yīng)具備下列基本特性： </p> <p> (1)高的熱穩(wěn)定性。熱穩(wěn)定性是指鋼材在高溫下可長時間保持其常溫力學(xué)性能的能力。熱作模具工作時，接觸的是熾熱的金屬，甚至是液態(tài)金屬，所以模具表面溫度很高，一般為400～700℃。這就要求熱作模具鋼在高溫下不發(fā)生熱化，具有高的熱穩(wěn)定性，否則模具就會發(fā)生塑性變形，造成堆塌而失效。 </p> <p> <br /> </p> <p> (2)優(yōu)良的耐熱疲勞性，熱作模具的工作特點(diǎn)是反復(fù)受熱受冷，模具一時受熱膨脹，一時又冷卻收縮，形成很大的熱應(yīng)力，而且這種熱應(yīng)力是方向相反，交替產(chǎn)生的。在反復(fù)熱應(yīng)力作用下，模具表面會形成網(wǎng)狀裂紋(龜裂)，這種現(xiàn)象稱為熱疲勞，模具因熱疲勞而過早地斷裂，是熱作模具失效的主要原因之一。所以熱作模具鋼必須要有良好的熱疲勞性。 </p> <p> (3)較高的高溫強(qiáng)度和良好的韌性。熱作模具，尤其是熱鍛模，工作時承受很大的沖擊力，而且沖擊頻率很高，如果模具沒有高的強(qiáng)度和良好的韌性，就容易開裂。 </p> <p> <br /> </p> <p> <br /> 龍巖高速鋼模具鋼無錫鐵島模具鋼材有限公司提供模具鋼，有想法的可以來電咨詢！</p><div

<br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 深冷處理對鋼材的作用性： </p> <p> 1）超深冷能提高DC53模具鋼模具鋼及DY-SKH51高速鋼的硬度，韌性得到更充分的保證（在超深冷過程中是殘余碳化物轉(zhuǎn)變?yōu)轳R氏體）。 </p> <p> 2）超深冷也能讓DC53模具鋼模具工件具有精度保持性（尺寸穩(wěn)定性），防止在室溫因殘留奧氏體轉(zhuǎn)變而發(fā)生尺寸變化。 </p> <p> 3）深冷處理也能促使未轉(zhuǎn)變的奧氏體更多地轉(zhuǎn)變成馬氏體，進(jìn)一步提高硬度，從而提高零件的耐磨性和使用壽命；促進(jìn)微細(xì)碳化物的彌散析出，可以DC53模具鋼圓鋼的韌性。 </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，評價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，每一應(yīng)力循環(huán)的擴(kuò)展量;斷裂韌性反映材料對已存在的裂紋發(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。

模具鋼材是常用中碳調(diào)質(zhì)結(jié)構(gòu)鋼。該鋼冷塑性一般，退火、正火比調(diào)質(zhì)時要稍好，具有較高的強(qiáng)度和較好的切削加工性，經(jīng)適當(dāng)?shù)臒崽幚硪院罂色@得一定的韌性、塑性和耐磨性，材料來源方便。適合于氫焊和氬弧焊，不太適合于氣焊。焊前需預(yù)熱，焊后應(yīng)進(jìn)行去應(yīng)力退火。正火可改善硬度小于160HBS毛坯的切削性能。該鋼經(jīng)調(diào)質(zhì)處理后，其綜合力學(xué)性能要優(yōu)化于其他中碳結(jié)構(gòu)鋼，但該鋼淬透性較低，水中臨界淬透直徑為12~17mm，水淬時有開裂傾向。當(dāng)直徑大于80mm時，經(jīng)調(diào)質(zhì)或正火后，其力學(xué)性能相近，對中、小型模具零件進(jìn)行調(diào)質(zhì)處理后可獲得較高的強(qiáng)度和韌性，而大型零件，則以正火處理為宜，所以，此鋼通常在調(diào)質(zhì)或正火狀態(tài)下使用。由于良好的加工性能和多方位的處理工藝而成為鋼材中常用的加工材料。
