The RH vacuum refining technology is a vitally powerful method of producing clean steel. inner diameter traditional circular snorkel very difficult to be increased owing the metallurgical refractory thickness around snorkels and limitation area under chamber, limiting increase in efficiency. In order improve efficiency reactor, new designed degasser with an optimized arched established. This design replaces two structure greatly enhances cross-sectional snorkel. this study, flow...
The effects of rolling process and tempering temperature on microstructure mechanical performance experimental steel are studied. results show that the yield ratio elongation lower under noncontrolled rolling; off‐line after controlled rolling, tensile strength decrease slightly with increase in quenching temperature, decreases increases; condition ultrafast cooling (UFC), tempering, is fine martensite lath a large number precipitates, has highest elongation. With gradually, increases...
