| Abstract: | The possibility of controlled-rolling and controlled-cooling throughout the whole-line of high-speed wire rod mill is analyzed. The turbulent coolers used on rough mills and intermediate mills, and spray coolers on Stelmor conveyor were developed. Using these installations, the whole rolling processes can be performed in the austenite unrecrystallized zone and cooling control after finish rolling can be improved. Super steel has been produced from mild carbon steel in wire mill of Ansteel. The highest ReL is 470 MPa and Z is 67.5 %. The finest grain size of ferrite can reach 11.6 grade. The homogeneity of wire coils is also improved. |
| Keywords: | whole line austenite unrecrystallization controlled-rolling and controlled-cooling super steel |
