【摘要】 根据亲水亲油平衡(HydrophileLipophileBalance,HLB)理论,通过选择合适的乳化剂、抗磨剂、极压剂、防锈剂等添加剂,研制成适用于硬态黄铜(H68,H70和H72)的热轧乳化液,成功地应用于2Cr13不锈钢焊态热轧辊初轧多种硬态黄铜板材,取代了目前铜加工生产中,对于硬态黄铜普遍使用润滑脂间歇式地润滑热轧辊的工艺。生产结果表明:由于采用直接连续地喷射乳化液到轧辊表面,容易控制板形和板材的尺寸;提高了轧辊的抵抗磨损和防止粘辊的能力,克服了铜带表面的“黑丝”、“发黄”和粗糙化现象,稳定地改善了铜带表面的质量,降低了工人劳动强度,从而极大地提高了生产效率并延长了轧辊的使用寿命。更多还原

【Abstract】 According to hydrophile-lipophile balance (HLB) theory,a kind of novel emulsion used for hot rolling process of hard brass (H68,H70 and H72),in which the roller material was the welded stainless steel 2Cr13,was developed by controlling of the compositions of emulsion,such as emulsifying,antiwear,extreme pressure,antirust and so on,which replaced the current hot rolling process lubricated by discontinuously brushing grease to hot roller surface.The actual hot rolling results prove that it is easy to control the accuracy and size of the brass sheet with the emulsion jet.This new process increases the antiwear and anti-galling abilities of the rollers,and improves the surface quality of the brass sheet.For example,the formation of deep,dark streaks in the hot rolled copper sheet is prevented,galling and roughening of the roller surfaces during hot rolling is reduced and it also saves labor,and increases production efficiency and the service life of the hot roller greatly.更多还原
