n.刚铝玉(人造刚玉)
Labor hygiene of a brown alundum grinding material workshop ofTaiyuan emery wheel factory was investigated. 本文对太原砂轮厂生产棕刚玉磨料的车间进行了劳动卫生调查。
The thermal physical properties of brown alundum and the matches of brown alundum coating have been studied. 研究了棕刚玉的热物理性质
The forming condition of crystal and closed pore in tabular alundum produced with electric melting is estimated and determined theoretically. 从原理上判断和估计了电熔板状刚玉结晶体和阔气孔的形成条件。
The results have shown that the brown alundum coatings are high-class neutral refractory coatings and are used with success in iron and steel cast-ings. 试验结果表明
The conception and technology of producing tabular alundum with electric melting and the composition and structure of tabular alundum are expounded in this article. 阐明了用电熔法生产板状刚玉的构思和工艺要点、板状刚玉的组成与结构。
The results have shown that under the high velocity impactig of alundum particles, high manganese steel had the typical erosion behaviors of ductile metals. 结果表明，在高速氧化铝粒子冲蚀下，高锰钢仍具有典型延性材料的冲蚀磨损特性。
