The invention discloses a long-life steelmaking tundish dry material processing and using process, which comprises a steelmaking tundish dry material processing process and a steelmaking tundish dry material using process, and the steelmaking tundish dry material processing process comprises formula determination, raw material selection, safe production, and delivery after production dates and batches are marked. The steelmaking tundish dry material using process comprises the steps that technicians are arranged on site to track construction; the technicians track the steel casting process and measure the temperature of the tundish shell at any time; the erosion thickness of a slag line and the sintering thickness of a tundish wall are measured after the tundish is used off line, the tundish is tracked and turned, and the difficulty of turning the tundish is observed; and test data is summarized. According to the dry material, the service time of the tundish can be greatly prolonged and can reach 50 hours or more, the erosion of an impact area and a slag line position is relatively shallow and is about 1/3 of the construction thickness, the tundish wall is basically not eroded, the temperature of a tundish shell is lower than 280 DEG C, the potential safety hazard of the tundish is solved, meanwhile, the cost of refractory materials per ton of steel is reduced, and the tundish runs safely.
本发明公开了一种长寿命炼钢中间包干式料加工及其使用工艺，包括炼钢中间包干式料加工工艺和炼钢中间包干式料使用工艺，炼钢中间包干式料加工工艺包括确定配方；原料选择；安全生产、标明生产日期及批次后发货；炼钢中间包干式料使用工艺包括现场安排技术人员跟踪施工；技术人员跟踪浇钢过程，随时测量中间包外壳温度；中间包使用完毕下线后测量渣线侵蚀厚度和包壁烧结厚度，跟踪翻包，观察翻包难易程度；总结试验数据；本发明中干式料可大大提高中间包的使用时间，可达到50小时以上，冲击区、渣线位置侵蚀较浅，约施工厚度的1/3，包壁基本无侵蚀，中间包外壳温度低于280℃，解决中间包安全隐患，同时降低吨钢耐材成本，使中间包安全运行。
