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。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。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(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 /> 泰安模具鋼零售無錫鐵島模具鋼材有限公司可大量供應(yīng)品質(zhì)模具鋼。</p><div

就國(guó)內(nèi)外使用的模具鋼材而言，模具鋼密度一般都在7.85左右，通常模具鋼是鍛造件，密度在8000-8400千克/立方米。不同模具鋼材中加入的合金元素比例不一樣，模具鋼密度會(huì)有小范圍的差別。 </p> <p> 密度是物質(zhì)的特性之一，每種物質(zhì)都有一定的密度，不同物質(zhì)的密度一般是不同。因此我們可以利用密度來鑒別物質(zhì)。所以我們可以根據(jù)密度公式ρ=M/V，計(jì)算出任意一種模具鋼的密度。 </p> <p> 根據(jù)密度公式：ρ=m/v，也就是說決定模具鋼質(zhì)量和體積的因素決定了模具鋼密度。那么從微觀的角度來講的話，就是分子量和分子間隙共同決定物質(zhì)的密度。體積、大小、質(zhì)量、壓強(qiáng)、壓力和溫度影響物質(zhì)密度，雖然物質(zhì)密度物質(zhì)的本身屬性，它是一定的，但是物質(zhì)有各種狀態(tài)，當(dāng)物質(zhì)形成態(tài)的轉(zhuǎn)化的時(shí)候，密度才會(huì)變化。比如水，升溫可導(dǎo)致水的氣化，密度變小，加壓又可以使水蒸氣從新凝結(jié)為液態(tài)水，密度變大。

模具鋼材的硬度如何檢測(cè)？硬度是模具鋼重要的性能之一，對(duì)于快速、精確地測(cè)試模具鋼材硬度在模具制造和使用單位是非常關(guān)鍵的。同時(shí)也具有十分重要的意義，它可以提升模具質(zhì)量、制造水平和延長(zhǎng)模具的使用壽命。模具鋼是模具工業(yè)的主體材料，根據(jù)模具的服役條件、環(huán)境和狀態(tài)的不同，模具鋼應(yīng)具備不同的特性。在工業(yè)生產(chǎn)中，模具使用壽命和制成零件的精度、質(zhì)量、外觀性能，除與模具的設(shè)計(jì)技術(shù)、制造精度，以及機(jī)床精度和制造操作有關(guān)外，正確地選用模具材料和正確地執(zhí)行熱處理工藝也是至關(guān)重要的，資料顯示，模具早期失效因材料選擇不當(dāng)和材料內(nèi)部缺陷引起的大約占百分之十左右，而由熱處理不當(dāng)引起的約占百分之四十九。硬度是模具材料和成品模具的重要性能指標(biāo)。模具在工作時(shí)的受力狀態(tài)是復(fù)雜的，如熱作模具通常是在交變的溫度場(chǎng)下承受交變應(yīng)力作用，因此它應(yīng)具有良好的阻止模具轉(zhuǎn)變成較軟或塑性狀態(tài)的能力，并且在長(zhǎng)期工作環(huán)境下仍保持模具的形狀和尺寸精度不變。一般成品模具的硬度，冷作模具常選擇在59至60HRC，熱作模具常選擇在48HRC左右。

在高溫下高強(qiáng)度鋼的成型，EP油基潤(rùn)滑油失去了它的性能，無法在極溫應(yīng)用中提供物理的模具保護(hù)隔膜。而極溫型的IRMCO高固體聚合物潤(rùn)滑劑則可以提供必要的保護(hù)。隨著金屬在沖壓模具中變形，溫度不斷升高，EP油基潤(rùn)滑油都會(huì)變薄，有些情況下會(huì)達(dá)到閃點(diǎn)或者燒著（冒煙）。IRMCO高分子聚合物潤(rùn)滑劑一般開始噴上去時(shí)稠度低得多。隨著成形過程中溫度的上升，會(huì)變得更稠更堅(jiān)韌。實(shí)際上高分子聚合物極溫潤(rùn)滑劑都有“熱尋性”而且會(huì)粘到金屬上，形成一個(gè)可以降低摩擦的隔膜。這個(gè)保護(hù)屏障可以允許工件延展，在工件成型時(shí)沒有破裂和粘接，以此來控制摩擦和金屬流動(dòng)。有效的保護(hù)了模具，延長(zhǎng)了模具使用壽命，提高了沖壓的強(qiáng)度。

<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(zhǎng)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 /> 青島模具鋼加工</p><p
