高强度焊管去毛刺硬质合金刀具的研制

INVESTIGATION ON DEBURRIMG CUTTER FOR HIGH STRENGTH WELDED TUBE

去毛刺刀是清除焊管内外焊缝毛利的专用硬质合金刀具，其几何精度、合金的内在质量和性能指标均有较高的要求。本文介绍了为引进焊管机组生产线配套而研制的硬质合金去毛刺刀具，该合金通过采用强化球磨、添加组元等有效的工艺控制手段，使所研制的合金具有细晶粒组织和良好的高温使用性能，取代了进口产品，具有显著的经济效益和社会效益。

Deburring cutter,which is a special purpose cemented carbide tool for cutting off.burr mom welded seam on inner and outer surface of welded tube,has been strictly required for its geometric accuracy, inherent quality of alloy and property targets. The present paper has outlined the cemented carbide deburring cutter developed for completing the whole set of tube welding production line imported by our country. By strengthening ball grinding,adding elements etc. the alloy developed has fine grain structure and superior high temperature Performance,thus and so has been used for replacing imported products and exhibited obvious economic and socisl efficiency.
