n.剛鋁玉(人造剛玉)
Labor hygiene of a brown alundum grinding material workshop ofTaiyuan emery wheel factory was investigated. 本文對太原砂輪廠生產(chǎn)棕剛玉磨料的車間進行了勞動衛(wèi)生調(diào)查。
The thermal physical properties of brown alundum and the matches of brown alundum coating have been studied. 研究了棕剛玉的熱物理性質(zhì)
The forming condition of crystal and closed pore in tabular alundum produced with electric melting is estimated and determined theoretically. 從原理上判斷和估計了電熔板狀剛玉結(jié)晶體和闊氣孔的形成條件。
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. 試驗結(jié)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. 闡明了用電熔法生產(chǎn)板狀剛玉的構(gòu)思和工藝要點、板狀剛玉的組成與結(jié)構(gòu)。
The results have shown that under the high velocity impactig of alundum particles, high manganese steel had the typical erosion behaviors of ductile metals. 結(jié)果表明，在高速氧化鋁粒子沖蝕下，高錳鋼仍具有典型延性材料的沖蝕磨損特性。
