| Abstract: | Influences of chemical compositions of high speed steel, process parameters of eccentrically casting and combined quenching and tempering treatments on the performance of high speed steel roll collar have been investigated and results show that the roll collar manufactured under the eccentrically casting conditions using the high V and Nb content and hardened and tempered high speed steel as the starting material shows such excellent properties as small segregation and high and uniform hardness. The life expectancy of the collar used in the high speed wire rod prefinishing mill is 5 to 8 fold longer than that of the conventional alloy cast iron roll collar. |
| Keywords: | high V and Nb content high speed steel modification centrifuge speed centrifuge time roll collar |
