　　Congratulations on the national utility model patent for our roller gear products!

　　The utility model provides a split-type welded compound casting tooth roll used in a shaft furnace for pelletizing production. The toothed roller consists of driving roller diameter, intermediate roller body and supporting roller diameter, etc. The intermediate roller body is composed of chilled cast iron centrifugally cast by metal mold and seamless steel pipe. The heat and wear resistance of tooth roll was improved by compound casting. Replace steel with iron, reduce manufacturing cost; The welding seam was moved to the high temperature zone at the bottom of the furnace to reduce the thermal stress at the welding seam and avoid the welding seam list and water leakage, which would affect the normal production. The seamless steel tube has the same diameter as the front and rear rollers, which achieves true tubular cooling and improves the cooling effect.
