일반적으로, 제철소에서는 강판의 표면에 부착되어 있는 불순물을 제거하기 위하여 강판을 강알카리용액내로 침수시켜 표면의 불순물을 제거한 후 연속하여 강판을 물에 침수시켜 강판의 표면에 묻어 있는 강알카리용액을 씻어내는 공정을 거치게 되는데 이때 강판은 고무 롤에 의해 이송되어 진다.Generally, in steel mills, in order to remove impurities adhering to the surface of the steel sheet, the steel sheet is immersed in the strong alkali solution to remove the impurities from the surface, and the steel sheet is continuously immersed in water to wash the strong alkali solution on the surface of the steel sheet. The inner part is subjected to the process, in which the steel sheet is transferred by a rubber roll.
상기와 같은 종래의 고무 롤 조성물은 클로로 술폰화 폴리에틸렌(chloro sulfonated polyethylene : 이하 'CSM'이라함), 카본블랙, 황산바륨, 일산화납, 염화파라핀, 가소제, 산화마그네슘, 노화방지제가 배합된 조성물로 이루어져 있다.The conventional rubber roll composition is a composition containing chloro sulfonated polyethylene (hereinafter referred to as 'CSM'), carbon black, barium sulfate, lead monoxide, paraffin chloride, plasticizer, magnesium oxide, and antioxidant. consist of.
상기와 같은 종래의 고무 롤 조성물은 내마모성이 좋지 않아 강판의 이송시 발생되는 마찰로 인하여 고무 롤의 마모가 심하게 발생되어 고무 롤의 교체시기가매우 짧아 유지비용이 비싸고, 교체작업으로 인해 기계설비의 작동을 중단시켜야 함으로 작업생산성이 크게 저하된다는 문제점이 있었다.Conventional rubber roll composition as described above is not abrasion resistance is bad due to the friction generated during the transfer of the steel sheet is abrasion of the rubber roll is bad, the replacement time of the rubber roll is very short, the maintenance cost is expensive, due to the replacement operation of the mechanical equipment There is a problem that the work productivity is greatly reduced by having to stop the operation.
본 발명자는 이러한 문제점을 해결하기 위하여 CSM과 입자 크기가 작은 테프론 분말을 1차 배합한 후 이배합물을 카본블랙, 황산바륨, 일산화납, 염화파라핀, 가소제, 산화마그네슘, 노화방지제와 2차 배합함으로서 우수한 고무 롤 조성물을 제조할 수 있음을 알아내고 본 발명을 완성하였다.In order to solve this problem, the present inventors first blended CSM and teflon powder having a small particle size, and then secondly blended this mixture with carbon black, barium sulfate, lead monoxide, paraffin chloride, plasticizer, magnesium oxide, and antioxidant. It has been found that excellent rubber roll compositions can be made and the present invention has been completed.
본 발명의 목적은 고무 롤의 경도, 신장율 및 내마모성을 크게 행상시켜 고무 롤의 유효수명과 사용성을 현저히 연장시킴으로서 유지비용을 크게 낮추고, 제철소의 작업생산성을 향상시킬 수 있는 제철소의 기계장치용 고무 롤 조성물을 제공하고자 하는 것이다.An object of the present invention is to significantly improve the hardness, elongation and wear resistance of rubber rolls, thereby significantly extending the useful life and usability of the rubber rolls, thereby significantly lowering maintenance costs and improving work productivity of steel mills. It is to provide a composition.
