包钢的 meaning in English

steel clad
steel-clad

Abstract : according to the site condition of the bisc , a mathematical model of two - dimensional unsteady solidification and heat transfer was established for the bloom caster in the mold . the mathematical model was solved with a finite difference method to characterize the temperature profiles and thickness of the solidified shell in the mold , the effects of casting speed on thickness of the solidified shell are also studied
文摘:根据包钢的现场条件，建立了大方坯连铸机结晶器内二维非稳态凝固传热数学模型，采用有限差分法对数学模型求解，得出结晶器中铸坯的温度分布规律和凝固坯壳生成规律，同时研究了拉坯速度对坯壳生成厚度的影响
