八一鋼鐵(600581.SH):擬1.81億元投建鍊鋼廠150t產線新建寬厚板連鑄機項目
格隆匯3月7日丨八一鋼鐵(600581.SH)公佈,公司鍊鋼廠有120t、150t兩條轉爐產線。150t轉爐產線配置2套方坯連鑄機,供棒線產線;120t轉爐產線配置4套板坯連鑄機,供熱軋產線及寬厚板產線,現有最大規格1800mm×250mm。120t轉爐產線與熱軋產線銜接可熱送,但供應寬厚板產線需汽車運輸,不能實現熱裝熱送,經濟性較差,且120t轉爐產線板坯總量不能同時滿足供熱軋及寬厚板產線。寬厚板產線受坯型限制,產品最大單重<11.5t,對於風電用鋼,無法滿足風電塔筒成套供貨最大單重20t的供貨需求。容器鋼、水電用鋼也存在類似最大單重需求,均需鍊鋼廠提供更大規格的板坯原料。
公司於2025年3月7日召開第八屆董事會第二十次會議,審議同意了《八一鋼鐵關於鍊鋼廠150t產線新建寬厚板連鑄機項目的議案》,本項目總投資額估算爲18072.86萬元。
項目主要建設內容:1.保護性拆除
150t 產線現有
2#方坯連鑄機。2.新建一臺寬厚板坯連鑄機,包括在線及線下週轉件、維修區及配套中包維修、烘烤、除塵、通風、電氣、液壓等輔助設施。鑄坯斷面:250/320mm(預留
350mm)×1800~2300mm。3.輔助設施根據適用性拆除、利舊、改造或新增。大包迴轉臺利舊,新增澆鑄跨、切割跨、出坯跨板坯吊運行車,與寬厚板坯庫銜接提升機配套電控、液壓、水系統利舊改造等。
