<br /> </p> <p> 模具鋼按用途一般可分為冷作模具鋼、熱作模具鋼和塑料模具鋼三大類。 </p> <p> 冷作模具鋼 </p> <p> 冷作模具鋼主要用于制造對(duì)冷狀態(tài)下的工件進(jìn)行壓制成型的模具。如：冷沖裁模具、冷沖壓模具、冷拉深模具、壓印模具，菏澤進(jìn)口模具鋼、冷擠壓模具、螺紋壓制模具和粉末壓制模具等。冷作模具鋼的范圍很廣，從各種碳素工具鋼、合金工具鋼、高速工具鋼到粉末高速工具鋼和粉末高合金模具鋼。 </p> <p> 熱作模具鋼 </p> <p> 熱作模具鋼主要用于制造對(duì)高溫狀態(tài)下的工件進(jìn)行壓力加工的模具，菏澤進(jìn)口模具鋼。如：熱鍛模具、熱擠壓模具、壓鑄模具，菏澤進(jìn)口模具鋼、熱鐓鍛模具等。常用的熱作模具鋼有：中高含碳量的添加Cr、W、Mo、V等合金元素的合金模具鋼；對(duì)特殊要求的熱作模具鋼，有時(shí)采用高合金奧氏體耐熱模具鋼制造。 </p> <p> 塑料模具鋼 </p> <p> 由于塑料的品種很多，對(duì)塑料制品的要求差別也很大，對(duì)制造塑料模具的材料也提出了各種不同的性能要求。所以，不少工業(yè)發(fā)達(dá)的國(guó)家已經(jīng)形成了范圍很廣的塑料模具用鋼系列。包括碳素結(jié)構(gòu)鋼、滲碳型塑料模具鋼、預(yù)硬型塑料模具鋼、時(shí)效硬化型塑料模具鋼、耐蝕塑料模具鋼、易切塑料模具鋼、整體淬硬型塑料模具鋼、馬氏體時(shí)效鋼以及鏡面拋光用塑料模具鋼等。

耐磨性可用模擬的試驗(yàn)方法，測(cè)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(rùn)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。

熱軋模具鋼分為錘鍛、模鍛、擠壓和壓鑄幾種主要類型，包括熱鍛模、壓力機(jī)鍛模、沖壓模、熱擠壓模和金屬壓鑄模等。熱變形模具在工作中除要承受巨大的機(jī)械應(yīng)力外，還要承受反復(fù)受熱和冷卻的作用，而引起很大的熱應(yīng)力。熱作模具鋼除應(yīng)具有高的硬度、強(qiáng)度、紅硬性、耐磨性和韌性外，還應(yīng)具有良好的高溫強(qiáng)度、熱疲勞穩(wěn)定性、導(dǎo)熱性和耐蝕性，此外還要求具有較高的淬透性，以保證整個(gè)截面具有一致的力學(xué)性能。對(duì)于壓鑄模用鋼，還應(yīng)具有表面層經(jīng)反復(fù)受熱和冷卻不產(chǎn)生裂紋，以及經(jīng)受液態(tài)金屬流的沖擊和侵蝕的性能。這類鋼一般屬于中碳合金鋼，碳質(zhì)量分?jǐn)?shù)在0.30%~0.60%，屬于亞共析鋼，也有一部分鋼由于加入較多的合金元素（如鎢、鉬、釩等）而成為共析或過(guò)共析鋼。常用的鋼類有鉻錳鋼、鉻鎳鋼、鉻鎢鋼等。 </p> <p> <br /> </p> <p> <br /> </p><p> <br /> </p> <p> <br /> </p> <p> <br /> </p> <p> 淬透性和淬硬性： </p> <p> 淬透性主要取決于鋼的化學(xué)成分和淬火前的原始組織狀態(tài)；淬硬性則主要取決于鋼中的含碳量。對(duì)于大部分的冷作模具鋼，淬硬性往往是主要的考慮因素之一。對(duì)于熱作模具鋼和塑料模具鋼，一般模具尺寸較大，尤其是制造大型模具，其淬透性更為重要。另外，對(duì)于形狀復(fù)雜容易產(chǎn)生熱處理變形的各種模具，為了減少淬火變形，往往盡可能采用冷卻能力較弱的淬火介質(zhì)，如空冷、油冷或鹽浴冷卻，為了得到要求的硬度和淬硬層深度，就需要采用淬透性較好的模具鋼。 [2] </p> <p> 淬火溫度和熱處理變形 </p> <p> 為了便于生產(chǎn)，要求模具鋼淬火溫度范圍盡可能放寬一些，特別是當(dāng)模具采用火焰加熱局部淬火時(shí)，由于難于準(zhǔn)確地測(cè)量和控制溫度，就要求模具鋼有更寬的淬火溫度范圍。 </p> <p> 模具在熱處理時(shí)，尤其是在淬火過(guò)程中，要產(chǎn)生體積變化、形狀翹曲、畸變等，為保證模具質(zhì)量，要求模具鋼的熱處理變形小，特別是對(duì)于形狀復(fù)雜的精密模具，淬火后難以修整，對(duì)于熱處理變形程度的要求更為苛刻，應(yīng)該選用微變形模具鋼制造 </p> <p> <br /> </p> <p> <br />

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(guò)早地?cái)嗔眩菬嶙髂＞呤У闹饕蛑?。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 /> 無(wú)錫鐵島模具鋼材有限公司提供模具鋼，期待您的光臨！廈門模具鋼零售</p><p

碳化物是絕大多數(shù)模具鋼的必需組分，除可溶于奧氏體的碳化物外，還會(huì)有部分不能溶于奧氏體的殘留碳化物。碳化物的尺寸、形態(tài)、分布對(duì)模具鋼的使用性能等有十分重要的影響。關(guān)于碳化物的尺寸、形狀和分布是與鋼的冶煉方法、鋼錠的凝固條件以及熱加工變形條件等有關(guān)。過(guò)共析鋼的碳化物可能在晶界形成風(fēng)狀碳化物或是在加工變形中碳化物被拉長(zhǎng)而形成帶狀碳化物或者二者兼有，萊氏體模具鋼中，存在一次碳化物和二次碳化物，在熱變形的過(guò)程中，網(wǎng)狀的共晶碳化物大多可以破碎，碳化物先沿變形方向延伸，產(chǎn)生帶狀，隨著變形程度的增加，碳化物變得均勻、細(xì)小。碳化物的不均勻性對(duì)淬火變形、開裂、鋼材的力學(xué)性能的影響較大。
