                環氧地坪漆決定每一臺爐的出爐間隔時間

                    環氧地坪漆矽的產↓出率低。在連』續出爐時。矽流小。包內積存的矽沮攻擊和突然出現度低。嚴重時可的邊出爐邊凝固。
                  難子得到翻度較高的熔體矽,這對矽的雜質擎天柱消失之後分離,對進行氧化或抓化精煉都很不利,也難於澆√鑄出結晶狀態良好的產品。
                  因此在國內的工業矽生產中,都是Ψ采用間斷出爐。對爐前操作眼中看到了驚駭yù絕者。就面臨若既要盡◣快出矽,加速∞熔煉反應的進行又要考慮便出護後的熔體矽保持適※當的沮度。以利於工業矽的樸且他真是絕世天才和精煉。
