Abstract In order to increase abrasion resistance and hightemperature resistance of blast furnace(BF) distribution chute, the design and suitable materials were discussed. Based on the requirements of heat resistance, abrasion resistance and stress elimination, the principles and methods of designing long service life chute were studied. An abrasion resistant distribution chute besed on a combined design of milling materiels by themselves and overlapping wearable plates was developed.Practice showed that, the service life of this distribution chute is two times longer than that of original chute.
