| Abstract: | Increasing Si/C ratio in chemical composition of low chromium heat resistant cast iron decrased the remaicder stress and increased the strength/stress ration of cast iron uhile obtainong the relatively high strength stablely, uhich avoided the fracture of rectangular valve effectively. The good effect of Si's improving the high temperature resistant properties of cast iron was analysed. The chromium content ciuld be appropriately increased when the Si content was increased. |
