[美国《内部研究与试制》1975年4卷1期报道)日本钢铁公司采用振动压实技术更换高炉铁水沟衬,较捣筑方法经济、迅速,效果也更好。这种技术是在U形铁水沟内的耐火材料上放加权模板,用电机方法使模板振动。全尺寸试验的结果表明,这种技术的优点是t换衬时间减少90％,由捣筑法所需的30小时减为3小时,②铁水沟寿命延长50％,由承受1500。C [US Internal Research and Trial Production, 1975, Vol. 4, No. 1] Japanese steel companies use vibro-compaction technology to replace the blast-furnace hot metal gully lining, which is economical, rapid and effective. This technique involves placing a weighted template on the refractory in the U-shaped gutter and vibrating the template using a motor method. The full-scale test results show that this technique has the advantage of reducing t-liner time by 90%, from 30 hours required by the pounding method to 3 hours, and ② increasing the life of the iron ditch by 50% from 1500.
