The composite roll of high speed steel has the synthetical life of over ten times more than traditional high cr cast iron roll. now the research and production of the high speed steel for roll are very drastic. in this thesis, the microstructure, heat treatment and performance of high speed steel fe - 2 % c - 4 % v - 4 % mo - 5 % cr - x % w ( wt ) are studied systematically by using metallograph, method of lattice, xrd, sem, eds and hardness

鋼輥套的生產工藝研究
The effect of compound casting technology and compound modification on the properties of high speed steel roll collar was studied. the results showed that compound high speed steel roll collar with high and even hardness and good bond between outer and inner layers could be gained when the modified colbalt free high speed steel in outer layer and nodular iron inner layer in connection with appropriate rotational speed of centrifugal machine, pertinent pouring interval between two kinds of the melt and moderate pouring temperature as well as surface induction heat treatment were chosen. it is indicated in industrial use that the service life of compound roll collar is higher by 5 times than that of high chromium cast iron collar
