护坡砖模具的热处理制度
护坡砖模具的化学成分,晶粒度,纯净度,碳化物以及夹杂物等的数量、形貌、尺寸大小以及分布情况,还有护坡砖模具的热处理制度和热处理后得到的金相组织等因素都对钢的韧性带来很大的影响.特别是钢的纯净度以及热加工变形情况对于其横向韧性的影响更为明显.钢的韧性、强度与耐磨性往往是相互矛盾的.因此,要合理地选择钢的化学成分并且采用合理的精炼、热加工以及热处理工艺,以使模具材料的耐磨性、强度还有韧性达到佳的配合.
The chemical composition, grain size, purity, quantity, morphology, size and distribution of carbides and inclusions, as well as the heat treatment system and metallographic structure of the slope protection brick die after heat treatment have great influence on the toughness of the steel. Especially the purity of the steel and the hot working deformation of the steel. The effect of the situation on the transverse toughness is more obvious. The toughness, strength and wear resistance of steel are often contradictory. Therefore, it is necessary to select the chemical composition of steel reasonably and adopt reasonable refining, hot working and heat treatment processes so as to achieve a good match of wear resistance, strength and toughness of die materials.
