Continuous channel method of forming a twin roll strip casting process for casting roll surface

摘要

[Challenge] On it is possible to prevent the occurrence of dents, to produce defect-free slab, casting subject steel grades that may occur similar defects or dents as well as a high manganese steel, volatile large amount of gas is generated to provide can be also widely used for the continuous gas discharge channel forming method of the twin roll strip casting the casting roll surfaces. [MEANS FOR SOLVING PROBLEMS] A method of coating a photosensitive photoresist on the entire surface of the casting roll, a step of patterning a photosensitive photoresist that is the coating, the method of developing the surface of the casting roll of the patterned casting exposed at the development step and a step of etching the metal surface of the roll surface.
