一种板坯去毛刺机用刀片及其制造方法
摘要：
本发明公开了一种板坯去毛刺机用刀片及其制造方法，其特征在于：所述刀片基体材质采用6CrMnSi2Mo1V制备，基体材质的组份重量百分比如下：C:0.40-0.70%、Si:0.50-1.2%、Mn:0.20-0.50%、Cr:4.00-6.00%、Mo:0.50-2.00%、V:0.30-1.50%、P≤0.02%、S≤0.02%、余量为铁及不可避免的杂质元素。在刀片顶端面与棱边处涂覆双相硬质涂层，干燥后置于真空烧结炉内烧结。结构和工艺简单、成分独特，提高刀片的耐磨性、且不容易剥落和断裂。相对于45刚的基材刀片，能够完全适应板坯去毛刺需求。
摘要（英）：

The invention discloses a blade for a slab deburring machine and a manufacturing method thereof. The blade is characterized in that a substrate of the blade is prepared from 6CrMnSi2Mo1V, and the substrate is prepared from the following components according to weight percent: 0.40 to 0.70% of C, 0.50 to 1.2% of Si, 0.20 to 0.50% of Mn, 4.00 to 6.00% of Cr, 0.50 to 2.00% of Mo, 0.30 to 1.50% of V,less than or equal to 0.02% of P, less than or equal to 0.02% of S and the balance of Fe and inevitable impurity elements. Biphase hard coatings are applied to the top end surface and edges of the blade, and the blade is put in a vacuum sintering furnace to be sintered after the biphase hard coatings are dried. The blade has the advantages of simple structure and process, unique component and difficulty in peeling and breaking, and the wear resistance of the blade is increased. Compared with a 45 steel blade, the slab deburring requirement can be completely satisfied.
