由鞍钢民用建筑公司研究成功了氧炔焰切割混凝土新技术。它是利用氧乙炔混合气体燃烧所产生的高温,把混凝土熔融,并在高压氧气的旋流作用下将溶渣排除,达到成孔分离的目的。这一新技术操作简便,不需特殊设备,
The new technology of oxyacetylene flame cutting concrete has been successfully studied by Angang Civil Construction Company. It uses the high temperature produced by the combustion of oxyacetylene gas mixture to melt the concrete and remove the slag under the effect of high pressure oxygen swirling to achieve the goal of pore separation. This new technology is easy to operate and requires no special equipment.
