selection of sizes:The normal diameter of stainless stell fiber is 0.-07mm with a length of 20-60mm.To avoid agglomeration during stirring. the ratio of the length to the diameter should be noted that if a process of jet spray is applied,stainless steel fiber of a shorter length(<25mm) shout be selected,otherwise the spray jet shall be blocked;

selection of the grade:The grades of steel fiber should be suitably selected based on the temperature and atmosphere. See Table;

selection of the ratio:The ratio of the weight of steel fiber in refractory materials is 2-4%. The heavier the steel fiber is , the more strengthening effect it will have.If it is too
high,then the more difficult installation.

selection of the packing:Steel fiber should be first spread evenly into the refractory
materials,and mixe in a dry state and then in a wet state.To avoid the difficulty of
installation due to agglomeration, a packing of an orderly array in paper boxes should be first considered.
