Apparatus For Preventing Damage To Casting Rolls In Strip Casting Machine |
| 摘要 |
The apparatus for preventing damage to casting rolls includes: a roll pressing force detection unit measuring a roll pressing force applied to the casting rolls; a foreign object determination unit determining whether foreign objects have been introduced to the casting rolls based on the measured roll pressing force; a roll gap instruction value generation unit generating a roll gap instruction value by adding a preset roll gap amount to the set roll gap if it is determined that foreign objects have been introduced to the casting rolls; and a roll gap control unit controlling a roll gap between the casting rolls based on the roll gap instruction value. Therefore, surfaces of the casting rolls may be less damaged by foreign objects. |

1. An apparatus for preventing damage to casting rolls in a strip casting process in which the casting rolls are driven according to a target pressure value for maintaining a set roll gap, the apparatus comprising:
a roll pressing force detection unit measuring a roll pressing force applied to the casting rolls; a foreign object determination unit determining whether foreign objects have been introduced to the casting rolls based on the measured roll pressing force; a roll gap instruction value generation unit generating a roll gap instruction value by adding a preset roll gap amount to the set roll gap if it is determined that foreign objects have been introduced to the casting rolls; and a roll gap control unit controlling a roll gap between the casting rolls based on the roll gap instruction value. |
