咬合抗力實際就是發(fā)生"冷焊"時的抵抗力,。該性能對于模具材料較為重要。試驗時通常在干摩擦條件下,,把被試驗的工具鋼試樣與具有咬合傾向的材料(如奧氏體鋼)進行恒速對偶摩擦運動,,以一定的速度逐漸增大載荷,,此時,轉矩也相應增大,,該載荷稱為"咬合臨界載荷",,臨界載荷愈高,標志著咬合抗力愈強,。
因此,,鋼鐵企業(yè)要根據(jù)國內模具制造業(yè)發(fā)展的趨勢和模具市場的需求,緊抓研制開發(fā)---,、高韌性,、耐腐蝕、高的模具鋼新品種,,使國產的熱作和冷作模具鋼達到---水平,。相信在未來的日子,,我們生產模具鋼的和技術會越來越好,模具鋼的市場也會得到更快---的發(fā)展,將會帶領國內模具鋼產業(yè)邁上更高層次的發(fā)展,。美好的未來,,我們拭目以待,。淬火溫度和熱處理變形為了便于生產,,要求模具鋼淬火溫度范圍盡可能放寬一些,---是當模具采用火焰加熱局部淬火時,,由于難于準確地測量和控制溫度,,就要求模具鋼有更寬的淬火溫度范圍。模具在熱處理時,,尤其是在淬火過程中,,要產生體積變化、形狀翹曲,、畸變等,,為---模具,要求模具鋼的熱處理變形小,,---是對于形狀復雜的精密模具,,淬火后難以修整,對于熱處理變形程度的要求更為苛刻,,應該選用微變形模具鋼制造,。
熱軋模具分為錘鍛、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---的機械應力外,還要承受反復受熱和冷卻的作用,,而引起很大的熱應力,。熱作模具鋼除應具有高的硬度、強度,、紅硬性,、耐磨性和韌性外,還應具有---的高溫強度,、熱疲勞穩(wěn)定性,、導熱性和耐蝕性,此外還要求具有較高的淬透性,,整個截有力學性能,。對于壓鑄模用鋼,還應具有表面層經反復受熱和冷卻不產生裂紋,,以及經受液模具鋼態(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,碳分數(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)而成為共析或過共析鋼。常用的鋼類有鉻錳鋼,、鉻鎳鋼,、鉻鎢鋼等。合金結構鋼:40crnimoa,,20crni2mo ,,20crmnmo ,40crmnmo ,,35crmo ,,42crmo,4140,,4130,,sae8620,45crnimova,,16mncr5(15crmn),,38crmoala,20mncr5(20crmn),,18cr2ni4wa ,,12crni3,,20cr2ni4a ,35crmnsia,,30crmnsia,,18crni3mo,25cr2mov,,22crmoh,,20crmnmo,20-30crmnti,,25crnimov,,20crnimo,g20crni2mocr12,,cr12mov,,cr12mo1v1,h13,,718#,,p20,5crnimo,,5crmnmo,,crwmn,9crsi,,9cr2,,5-6crw2si,8cr3,,9mn2v,,4cr5w2vsi,30cr3w,,4cr2movni(b2),,skd11.,30cr2ni2mo,,17cr2ni2mo,,17crnimo6,18crnimo7,,34crnimo6,,30crnimo8,40-45crni,,20ni4mo,,20-30crmnsini2a,38crsi,34crni1mo,,12crni3a,,20crni 30crni3a,34-37crni3a,,34-37crni3moa,,12cr2ni4a,20cr2ni4a,,18-25cr2ni4w,,25cr2mov,25cr2mo1v,,12crmo,,12cr1mov,35crmov,,45cr2mov,,18crni3moa,20crni3moa,,25crni3moa,,,22simncrni2mova,,5crw2si.等,。
