This investigation also finds that different lithology have different physical properties and the slaggy basalt, the amygdaline basalt and the volcanic breccia have the best physical properties.

不同岩性火山岩的物性也有较大的差别，并以熔渣状玄武岩、杏仁状安山岩、火山角砾岩为好；

It is put forward to adjust burden proportion and to add a small amount of limestone so as to improve the slaggy properties and to raise the technical and economic benefits of technological process.

提出了调整配料比例，补加少量石灰，以改善炉渣性质，提高生产过程中的技术经济效益。
