Abstract

연속전기도금에 사용되는 통전롤에 관한 것이다.The present invention relates to a rolling roll used for continuous electroplating.

본체 표면 중앙부에 환설된 전기전도링과 그 양단에서 본체 표면 양단부에 형성된 탄성 중합체 피복층의 경계부에서, 탄성중합체 피복층내에 전기전도링의 열팽창율과 비슷하거나 이보다 약간 작은 열팽창율을 갖는 금속링을 매설한 통전률이 제공된다. 이 매설된 삽입링에 의해 전기전도링과 탄성중합체 피복층 경계부근의 급격한 열팽창차이를 완만하게 하여 단차를 줄이고 강판과 전기적인 접촉 및 실링을 양호하게 함으로써 제품 결함의 감소, 통전롤 본체의 부식 방지, 롤수명 연장등 여러 효과를 가져온다.In the boundary of the conductive ring annular to the central part of the main body surface and the elastomer coating layer formed at both ends of the main body surface, a metal ring having a thermal expansion rate similar to or slightly less than that of the conductive ring is embedded in the elastomeric coating layer. Through current is provided. This buried insertion ring smoothes the rapid thermal expansion difference between the conductive ring and the elastomeric coating layer boundary, reducing the level difference, and making good electrical contact and sealing with the steel plate, thereby reducing product defects and preventing corrosion of the roll body. It has various effects such as extending the life of the roll.
