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(jìn)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);棕剛玉涂料的配方及性能.
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;所研究的棕剛玉涂料是一種優(yōu)質(zhì)的中性抗粘砂涂料;適用于粘土砂、水玻璃砂及樹脂自硬砂的鑄型和型芯.
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)。
