在高溫下高強度鋼的成型，EP油基潤滑油失去了它的性能，無法在極溫應用中提供物理的模具保護隔膜。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。隨著金屬在沖壓模具中變形，溫度不斷升高，EP油基潤滑油都會變薄，有些情況下會達到閃點或者燒著（冒煙）。IRMCO高分子聚合物潤滑劑一般開始噴上去時稠度低得多。隨著成形過程中溫度的上升，會變得更稠更堅韌。實際上高分子聚合物極溫潤滑劑都有“熱尋性”而且會粘到金屬上，形成一個可以降低摩擦的隔膜。這個保護屏障可以允許工件延展，在工件成型時沒有破裂和粘接，以此來控制摩擦和金屬流動，三明模具鋼零售，三明模具鋼零售。有效的保護了模具，延長了模具使用壽命，三明模具鋼零售，提高了沖壓的強度。

給大家分享一下我們常用的熱作模具鋼。（1）錘鍛模用鋼。一般說來，錘鍛模用鋼有兩個問題比較突出一是工作時受沖擊負荷作用．故對鋼的力學性能要求較高，特別是對塑變抗力及韌性要求較高；二是錘鍛模的截面尺寸較大（＜400mm）故對鋼的淬透性要求較高，以保證整個模具組織和性能均勻。 </p> <p> （2）熱擠壓模用鋼，熱擠壓模的工作特點是加載速度較慢，因此，模腔受熱溫度較高，通?？蛇_500一800℃。對這類鋼的使用性能要求應以高的高溫強度(即高的回火穩(wěn)定性）和高的耐熱疲勞性能為主。對ak及淬透性的要求可適當放低。一般的熱擠壓模尺寸較小，常小于70～90mm。 </p> <p> （3）壓鑄模用鋼。壓鑄模用鋼的使用性能要求與熱擠壓模用鋼相近，即以要求高的回火穩(wěn)定性與高的熱疲勞抗力為主。所以通常所選用的鋼種大體上與熱擠模用鋼相同．如常采用4CrW2Si．和3Cr2W8V等鋼。但又有所不同如對熔點較低Zn合金壓鑄模．可選用40Cr、30CrMnSi及40CrMo等；對Al和Mg合金壓鑄模，可選用4CrW2Si、4Cr5MoSiV等對Cu合金壓鑄模．多采用3Cr2W8V鋼。

<p> 由于熱作模具鋼工作條件的特點，因此會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、空氣等介質冷卻模腔的表面。因此．熱模的工作狀態(tài)是反復受熱和冷卻，從而使模腔表層金屬產(chǎn)生反復的熱脹冷縮，即反復承受拉壓應力作用．其結果引起模腔表面出現(xiàn)龜裂，稱為熱疲勞現(xiàn)象，由此，對熱模具鋼提出了第二個基本使用性能要求．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鋼的導熱性。鋼的導熱性高，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。一般認為鋼的導熱性與合碳量有關，含碳量高時導熱性低，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．會導致鋼的硬度和強度下降．也是不利的。②鋼的臨界點影響。通常鋼的臨界點（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。從而提高鋼的熱疲勞抗。
