在高溫下**度鋼的成型，揚(yáng)州SKD11模具鋼，EP油基潤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)，揚(yáng)州SKD11模具鋼。有效的保護(hù)了模具，延長了模具使用壽命，揚(yáng)州SKD11模具鋼，提高了沖壓的強(qiáng)度。

耐磨性可用模擬的試驗(yàn)方法，測出相對(duì)的耐磨指數(shù)，作為表征不同化學(xué)成分及組織狀態(tài)下的耐磨性水平的參數(shù)。決定模具使用壽命重要的因素往往是模具材料的耐磨性。模具在工作中承受相當(dāng)大的壓應(yīng)力和摩擦力，要求模具能夠在強(qiáng)烈摩擦下仍保持其尺寸精度。模具的磨損主要是機(jī)械磨損、氧化磨損和熔融磨損三種類型。為了改善模具鋼的耐磨性，就要既保持模具鋼具有高的硬度，又要保證鋼中碳化物或其他硬化相的組成、形貌和分布比較合理。對(duì)于重載、高速磨損條件下服役的模具，要求模具鋼表面能形成薄而致密粘附性好的氧化膜，保持潤滑作用，減少模具和工件之間產(chǎn)生粘咬、焊合等熔融磨損，又能減少模具表面進(jìn)行氧化造成氧化磨損。所以模具的工作條件對(duì)鋼的磨損有較大的影響。

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。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> H13鋼和3Cr2W8V鋼是我國目前使用廣的兩種熱作模具鋼，其中H13鋼因其良好的綜合力學(xué)性能及抗冷熱疲勞性能，能夠勝任一般模鍛工況的要求。但由于H13鋼作為中耐熱型熱作模具鋼，其工作溫度不宜超過600℃，且淬透性差不利于制造大截面模具，其應(yīng)用受到限制。 </p> <p> 3CrW8V鋼是我國較早使用且應(yīng)用廣的**熱性熱作模具鋼，其熱穩(wěn)定性良好，使用溫度可達(dá)650℃，但因其冷熱疲勞性能和導(dǎo)熱性差，容易因冷熱疲勞而產(chǎn)生龜裂甚至斷裂。而中合金DM鋼為某科研團(tuán)隊(duì)自主研發(fā)的新型熱作模具鋼?？蒲腥藛T通過3種熱鍛模具鋼熱穩(wěn)定曲線的測定及微觀組織的觀察，對(duì)比分析3種鋼熱穩(wěn)定性能的優(yōu)劣及在熱穩(wěn)定過程中微觀組織的變化。熱穩(wěn)定試驗(yàn)的試樣尺寸為10mm×10mm×15mm，采用S2-5-12箱式爐分別將試樣在580、620、650℃保溫24h，然后采用69-1型洛氏硬度計(jì)，按照GB/T230.1-2000測試不同溫度下3種試驗(yàn)鋼的洛氏硬度值。

<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。
