</p> <p> 熱作模具鋼在工作時(shí)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(zhǎng)時(shí)間保持其常溫力學(xué)性能的能力。熱作模具工作時(shí)，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(huì)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(shí)受熱膨脹，一時(shí)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，泰安SKD61模具鋼。在反復(fù)熱應(yīng)力作用下，模具表面會(huì)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?cái)嗔?，是熱作模具失效的主要原因之一，泰安SKD61模具鋼。所以熱作模具鋼必須要有良好的熱疲勞性，泰安SKD61模具鋼。 </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(shí)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 /> 無錫鐵島模具鋼材有限公司生產(chǎn)的模具鋼物美價(jià)優(yōu)，歡迎新老客戶致電！泰安SKD61模具鋼</p><div

通常錘鍛模工作時(shí)．其模腔表面溫度可達(dá)300～400℃以上熱擠壓?？蛇_(dá)500一800℃以上；壓鑄模模腔溫度與壓鑄材料種類及澆注溫度有關(guān)。如壓鑄黑色金屬時(shí)模腔溫度可達(dá)1000℃以上。這樣高的使用溫度會(huì)使模腔表面硬度和強(qiáng)度明顯降低，在使用中易發(fā)生打垛。為此．對(duì)熱作模具鋼的基本使用性能要求是熱塑變抗力高，包括高溫硬度和高溫強(qiáng)度、高的熱塑變抗力，實(shí)際上反映了鋼的高回火穩(wěn)定性。由此便可以找到熱模具鋼合金化的第一種途徑，即加入Cr、W、Si．等合金元素可以提高鋼的回火穩(wěn)定性。

模具鋼有哪些應(yīng)用？適合要求高光整度的模具。該鋼氮化后的表層硬度可以達(dá)到650~700HV,制品數(shù)量可達(dá)到100萬模次以上。特別適合厚度大于400mm的塑料模模架。適用于各種高拋光度和大型塑料模具,如家電、汽車行業(yè)、辦公設(shè)備用塑料模具等。用于大型塑料模具模架上,如汽車保險(xiǎn)杠、電視機(jī)外殼模具等。2738添加約1%的鎳含量，預(yù)硬度好。由于添加了鎳元素，提高了其淬透性能，大截面厚板硬度分布均勻。主要應(yīng)用在大型塑膠模具、模架上，如汽車保險(xiǎn)杠、電視機(jī)外殼模具等。適合要求高光整度的模具，如生產(chǎn)硬膠（PS）及超不淬膠（ABS）等，其特點(diǎn)為：優(yōu)良的加工性能、易切削拋光和電蝕性能。 </p> <p> 2738鋼材中加入鎳成分，硬度均勻，擁有優(yōu)越的加工性能及拋光性能。主要使用于高要求的塑膠模具，適合電視機(jī)、傳真機(jī)、家電塑膠部件、汽車部件等要求一定拋光性的塑膠模。 </p> <p> 塑料模具鋼材2738H，是在2738的基礎(chǔ)上加硬改良而成，鋼材中加入鎳成分，硬度均勻，擁有優(yōu)越的加工性能及拋光性能。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 大型模具鋼需求量將逐年增加；模具的精度越來越高，要求鋼材的質(zhì)量好，尺寸穩(wěn)定性好；塑料模具鋼、壓鑄模具鋼的需求量不斷增加；各類型模具鋼的需求量不斷增加，低檔次模具鋼過剩；另外，隨著模具標(biāo)準(zhǔn)件應(yīng)用日益廣，模具標(biāo)準(zhǔn)化、商品化程度的提高，對(duì)于模具鋼產(chǎn)品質(zhì)量、品種規(guī)格以及交貨周期將提出更高的要求。此模具鋼類似于一個(gè)4330合金，潔凈鋼生產(chǎn)技術(shù)。它具有優(yōu)異的尺寸穩(wěn)定性，并一直工作鋅，鋁合金壓鑄，塑料和橡膠模具的現(xiàn)場(chǎng)驗(yàn)證，并形成所有類型的金屬片。它將接受各種形式的表面處理，包括火焰和感應(yīng)硬化，硬質(zhì)合金涂層，PVD和氮化。所以，SKD61模具鋼不僅有模具鋼的優(yōu)點(diǎn)，更有一些合金鋼產(chǎn)品的特點(diǎn)。將會(huì)帶動(dòng)國(guó)內(nèi)模具鋼產(chǎn)業(yè)的大發(fā)展。

模具鋼廠在生產(chǎn)模具鋼時(shí)，需要根據(jù)不同的模具來使用合適的鋼材。其中塑膠模具鋼的使用較為頻繁。一般情況下塑膠模具在制造過程中，需要花費(fèi)極多成本進(jìn)行加工和拋光，因此模具鋼廠在選用模具的材料時(shí)，應(yīng)當(dāng)在保證模具使用性能要求的基礎(chǔ)上，盡量的提高模具鋼的可加工性。那么，塑膠模具鋼如何選材呢？1、根據(jù)塑膠制品的種類選用 </p> <p> 不同的塑膠制品的質(zhì)量和加工方法不同，因此模具鋼廠可以根據(jù)塑料制品的質(zhì)量和加工方法的不同來選用適合的模具鋼，使得模具鋼在保證成本的同事，又具備可加工性。2、根據(jù)塑膠制品的大小和精度選用 </p> <p> 不同的塑膠制品的大小，精度等不盡相同，模具鋼廠可以根據(jù)塑膠制品不同的尺寸和精度的要求來進(jìn)行模具鋼的選用，對(duì)一些精度高，生產(chǎn)量大的塑膠制品，可以使用預(yù)硬化鋼材，可以有效的防止熱處理時(shí)模具鋼出現(xiàn)變形的可能。3、根據(jù)塑膠制品的復(fù)雜程度選用 </p> <p> 塑膠制品有些結(jié)構(gòu)比較簡(jiǎn)單，有些則相對(duì)較為復(fù)雜，那些相對(duì)復(fù)雜一些的塑膠制品，其加工工藝也會(huì)相對(duì)復(fù)雜一些，國(guó)內(nèi)**的模具鋼廠一般可以提前預(yù)見到產(chǎn)品需要經(jīng)歷的復(fù)雜程度，因此可以根據(jù)難易程度，選用具有易切削、熱處理時(shí)不易變形、耐磨性高等特質(zhì)的模具鋼來生產(chǎn)。

由于熱作模具鋼工作條件的特點(diǎn)，因此會(huì)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(duì)熱模具鋼提出了第二個(gè)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(shí)導(dǎo)熱性低，所以熱作模具鋼不宜采用高碳鋼。在生產(chǎn)中通常采用中碳鋼（C0.3%5～0.6%）合碳量過低．會(huì)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。
