</p> <p> <br /> </p> <p> H13鋼和3Cr2W8V鋼是我國(guó)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(guò)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(guó)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，青島SKD11模具鋼，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(guò)3種熱鍛模具鋼熱穩(wěn)定曲線(xiàn)的測(cè)定及微觀組織的觀察，青島SKD11模具鋼，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(guò)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)，青島SKD11模具鋼，按照GB/T230.1-2000測(cè)試不同溫度下3種試驗(yàn)鋼的洛氏硬度值。

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 />

在高溫下**度鋼的成型，EP油基潤(rùn)滑油失去了它的性能，無(wú)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(kāi)始噴上去時(shí)稠度低得多。隨著成形過(guò)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(méi)有破裂和粘接，以此來(lái)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。

偏析即鋼的成分與組織不均勻性的表現(xiàn)，這是在模具鋼的低倍組織的檢驗(yàn)中常存在的一種缺陷。是鋼錠在凝固過(guò)程中形成的，與鋼的化學(xué)成分和澆注溫度等有關(guān)。一般分為樹(shù)枝狀的偏析、方形偏析、點(diǎn)狀偏析等。由于樹(shù)枝狀的偏析的存在，使負(fù)然各個(gè)不同的方向的力學(xué)性能表現(xiàn)出明顯的差異。方形偏析是由于鑄錠結(jié)晶時(shí)，在柱狀晶的末端與錠心等軸晶區(qū)間，聚集了較多的雜質(zhì)和孔隙而形成的。嚴(yán)重的方形偏析，對(duì)鋼材的質(zhì)量的影響是顯著的，特別是切削加工量很大的零件或心部受力的模具零件。偏析除了影響模具鋼力學(xué)性能的等向性外，對(duì)模具的拋光性能也有一定的影響。因此，國(guó)外相關(guān)的標(biāo)準(zhǔn)中有嚴(yán)格的規(guī)定。

熱作模具鋼基本特性：(4)良好的耐磨性能，由于熱作模具制作時(shí)除受到毛坯變形時(shí)產(chǎn)生摩擦磨損之外，還受到高溫氧化腐蝕和氧化鐵屑的研磨，所以需要熱作模具鋼有較高的硬度和抗黏附性。 </p> <p> (5)良好的導(dǎo)熱性。為了使模具不致積熱過(guò)多，導(dǎo)致力學(xué)性能下降，要盡可能降低模面溫度，減小模具內(nèi)部的溫差，這就要求熱作模具鋼要有良好的導(dǎo)熱件能。 </p> <p> (6)良好的成形加工工藝性能，以滿(mǎn)足加工成形的需要。 </p> <p> (7)高淬透性。熱作模具鋼一般尺寸比較大，熱鍛模尤其是這樣，為了使整個(gè)模具截面的力學(xué)性能均勻，這就要求熱作模具鋼有高的淬透性能。 </p> <p> <br /> </p> <p> <br /> 模具鋼質(zhì)量哪家好，歡迎咨詢(xún)無(wú)錫鐵島模具鋼材有限公司了解！威海模具鋼圓棒</p><p
