Aimed to bad permeability in sintering process while the bed of material is above 700 mm, a new technolo- gy-supporting sintering process was presented in this paper. The influence of stand-support and its height on techni- co-economic-indices were also studied under laboratory condition. The results showed that applying 350 mm stand- support was best; the bed shrinkage was decreased obviously; the productivity increased by maximum 15.2% and the drum index retained former level. The metallurgical properties of sinter were improved.
