Such as angle grinder, wire brush, needle beam pneumatic rust, and wind knock rust hammers, gear-type rotary rust, etc., are semi-mechanized equipment, tools, light, mobility, and to more thoroughly to rust , old coatings, the coating can be played on the shelf hair treatment, significantly more efficient than manual derusting increased up to 1 ~ 2m2 / h, but can not remove the oxide skin, the smaller surface roughness and can not achieve high-quality surface to deal with quality, ergonomic handle lower than the jet.

如角向磨光机、钢丝刷、风动针束除锈器、风动敲锈锤、齿型旋转除锈器等，属于半机械化设备，工具轻巧、机动性大，能较彻底去除锈、旧涂层等，能对货架涂层进行打毛处理，效率比手工除锈大大提高，可达1~2m2/h，但不能除去氧化皮，表面粗糙度较小，不能达到优质的表面处理质量，工效较喷射处理低。

It has been warranted through experiments and practical application that rare-earths-high-aluminium heat-resistant nodular iron has some intrinsic properties which are worthy of reconimandation, namely,that it will not scale after long periods of use at 1050-1100℃, will hardly break while being hammered into castings, runners or risers as the high-temperature tensile strength reaches 14-19 kg/mm2 at 800℃ or≥l3.3kg/mm2 at 900℃, with the room temperature strength close to HT 30-50 and the unnotched impact str...

本文介绍了稀土高铝耐热球墨铸铁的生产实践、化学成分；探讨了稀土作用及其用量和控制；论述了稀土和铝加入方式以及冷却速度对金相组织的影响；并对铸造工艺、铸件缺陷及分析、耐热性能及使用效果作了阐明。试验和使用证明：稀土高铝耐热球墨铸铁在1050～1100℃长时间工作不起氧化皮，热强度800℃时，14～19kg/mm~2，900℃时≥13.3kg/mm~2，室温强度近于HT30—54，a_k≈2～6kg·M/cm~2，锤击铸件或浇冒口，很难碎裂，并能机械加工。可以认为是以我国富产资源为原料，能用各种炉子熔炼、耐热和综合机械性能均较高硅、中硅中铝球铁、高铝片墨铸铁为高的一种耐热铸铁，也是镍铬系耐热材料较好的替代品。

Farther X-Ray diffraction, SEM, spectro-meter analysis reveals that the element Cr which sinters and induces phase transformation leads to relatively smaller oxide weight-loss of 40Cr, then the oxidation laws of two steels are surmarized.

用XRD、SEM、EDS等方法对两种钢的氧化皮进行分析，得出40Cr钢氧化失重率相对减小的原因是因为Cr合金元素的烧结引起的相变所致。
