| titleOfInvention | Casting blank production process of solidification tail end large-reduction continuous casting machine |
| abstract | The invention provides a control method and a production process of a continuous casting machine with a solidification tail end under large pressure, wherein the control modes of the casting times of the continuous casting machine are divided into 10 control modes, namely a maintenance mode, a roll gap measurement mode, a preparation mode, a dummy ingot loading mode, a point-action dummy ingot loading mode, a holding mode, a casting mode, a tundish replacement mode, a redraw mode and a tail blank pulling mode, and the 10 control modes correspond to different segment roll gaps under different segment control modes. The invention avoids the accidents of slipping, blank stagnation, steel leakage and the like which are easily caused when the head and the tail blank of the dummy ingot impact the guide roller of the sector section and the pulling speed is increased or reduced in production. The provided reduction total amount calculation method adopts different reduction total amounts according to the metallurgical and physical characteristics of casting blanks with different sections and different steel types, and accurately and reasonably controls the reduction amount of each sector section, so that the extrusion discharge of solute segregation molten steel in a low solid phase region and the effective welding of shrinkage cavity defects in a high solid phase region are realized, and the quality of the casting blanks is effectively improved. |
