            常用熱作模具用鋼

            來源:http://www.environmentandpeople.net/ 日期:2021-03-10 發布人:admin


            (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。
            (1) Steel for hammer forging die. Generally speaking, there are two prominent problems in the steel for hammer forging die. One is that it is subjected to impact load during working, so it has higher requirements on the mechanical properties of the steel, especially on the plastic deformation resistance and toughness; the other is that the cross-section size of hammer forging die is larger (< 400mm), so it has higher requirements on the hardenability of the steel, so as to ensure the uniform structure and performance of the whole die.
            常用錘鍛樓用鋼有5CrNiMo、5CrMnMo、5CrNiW、5CrNiTi及5CrMnMoSiV等。不同類型的錘眼模應選用不同的材料。對特大型或大型的錘鍛模以5CrNiMo為好.也可采用5CrNiTi、5CrNiW或5CrMnMoSi等。對中小型的錘鍛模通常選用5CrMnMO鋼。
            5CrNiMo, 5CrMnMo, 5crniw, 5crniti and 5crmnmosiv are commonly used for hammer forging. Different materials should be selected for different types of hammer eye dies. 5CrNiMo is better for extra large or large hammer forging die. 5crniti, 5crniw or 5crmnmosi can also be used. 5CrMnMo steel is usually used for medium and small hammer forging dies.
            (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70~90 mm .
            (2) The hot extrusion die is made of steel. The working characteristic of the hot extrusion die is that the loading speed is slow. Therefore, the heating temperature of the die cavity is high, usually up to 500-800 ℃. High high temperature strength (i.e. high tempering stability) and high thermal fatigue resistance are the main requirements for the service performance of this kind of steel. The requirements of AK and hardenability can be lowered appropriately. General hot extrusion die size is small, often less than 70 ~ 90 mm
            常用的熱擠壓模有4CrW2Si、3Cr2W8V及5%Cr型等熱作模具鋼.其中4CrW2Si.既可做冷作模具鋼,又可做熱作模具鋼.由于用途不同,可采用不同熱處理方法。作冷模時采用較低的淬火溫度(870—900℃)及低溫或中溫回火處理;作熱模時則采用較高的淬火溫度(一般為950一1000℃)及高溫回火處理。
            The commonly used hot extrusion dies are 4crw2si, 3Cr2W8V and 5% Cr type hot working die steels. 4crw2si can be used as both cold working die steel and hot working die steel. Due to different uses, different heat treatment methods can be used. Low quenching temperature (870-900 ℃) and low or medium temperature tempering are used for cold die, while high quenching temperature (950-1000 ℃) and high temperature tempering are used for hot die.
            (3)壓鑄模用鋼。從總體上看,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。
            (3) Die casting die steel. Generally speaking, the performance requirements of die casting die steel are similar to that of hot extrusion die steel, that is, high tempering stability and high thermal fatigue resistance are the main requirements. Therefore, the steel grade usually used is basically the same as that for hot extrusion die, such as 4crw2si. And 3Cr2W8V. For example, 40Cr, 30CrMnSi and 40CrMo can be used for Zn alloy die casting die with lower melting point; for Al and Mg alloy die casting die, 4crw2si and 4Cr5MoSiV can be used; for Cu alloy die casting die, 3Cr2W8V steel is mostly used.
            近年來.隨著黑色金屬壓鑄工藝的應用,多采用高熔點的鋁合金和鎳合金.或者對3Cr2W8V鋼進行Cr-Al-SI三元共滲,用以制造黑色金屬壓鑄模。國內外還正在試驗采用高強度的銅合金作黑色金屬的壓鑄模材料。
            In recent years, with the application of ferrous metal die-casting process, high melting point aluminum alloy and nickel alloy are often used, or Cr Al Si ternary infiltration is carried out on 3Cr2W8V steel to make ferrous metal die-casting die. At home and abroad, high strength copper alloy is also being used as die casting die material for ferrous metal.
