耐火砖成型模具工作面大,承受坚硬颗粒状的材料磨损、挤压和冲击,负荷条件恶劣,要求具有高的强度、硬度、耐磨性和良好的冲击韧性。我厂采用20Cr钢制作压砖模具,虽然质量比较稳定,但使用寿命低,消耗量大。国外多用冷模具钢和轴承钢。西德用Cr12、Cr12Mo钢制作,日本使用Cr12MoV和SUJ 2钢,一般国外的模具使用寿命为国产的4～5倍,一套模具可制砖十万块以上。我厂用Cr12MoV钢制造模具也取得良好效果。
Large refractory brick mold face, to withstand hard granular material wear, extrusion and impact, poor load conditions, requires high strength, hardness, wear resistance and good impact toughness. I plant using 20Cr steel brick making pressure brick, although the quality is relatively stable, but the service life is low, consumption. Cold mold steel and bearing steel abroad. West with Cr12, Cr12Mo steel production, the Japanese use Cr12MoV and SUJ 2 steel, the general service life of foreign molds for the domestic 4 to 5 times, a set of molds can make one hundred thousand or more brick. I plant with Cr12MoV steel mold also achieved good results.
