Scraper with wear-resistant layer at knife edge and production process of scraper
The invention discloses a scraper with a wear-resistant layer on a scraper edge and a production process of the scraper, belongs to the technical field of scrapers, and solves the problem that a wear-resistant layer of an existing scraper is severely abraded. The scraper comprises a scraper body, a flow guide groove, a first wear-resistant layer and a second wear-resistant layer, the scraper edge at the lower end of the scraper body extends forwards, and the end of the extending part is coated with the first wear-resistant layer; a first abrasion-resistant layer is arranged at the end corner of the lower end of the rear side of the cutter body, a diversion trench is formed above the cutter edge, a second abrasion-resistant layer is arranged at the end corner of the lower end of the rear side of the cutter body, and the first abrasion-resistant layer and the second abrasion-resistant layer are each composed of, by mass, 45%-73% of carborundum, 15%-30% of silica powder and 12%-25% of high-manganese steel welding flux. Various components with different particle sizes are mixed, the compactness of the scraper is improved, silica powder is added, the smoothness of the wear-resistant layer of the scraper can be improved, the hardness of the wear-resistant layer of the scraper can be further improved, and the wear resistance of the wear-resistant layer of the scraper is improved.
本发明公开了一种刀口带有耐磨层的刮刀及其生产工艺，属于刮刀技术领域，解决了现有刮刀耐磨层磨损大的问题，该刮刀包括刀体、导流槽、耐磨层一和耐磨层二，所述刀体的下端刀口处向前延伸，延伸部分的端部包覆有耐磨层一，且刀口处的上方开设有导流槽，刀体的后侧下端端角处设置有耐磨层二，所述耐磨层一和耐磨层二均由以下质量百分比的组分构成：金刚砂45～73％、硅微粉15～30％、高猛钢焊料12～25％。采用粒径不同的多种组分混合，提高提高刮刀的致密度，且增加硅微粉，不仅能够提高刮板耐磨层的光滑度，还能够进一步提高刮刀的耐磨层的硬度，提高其耐磨性。
