新余钢铁有限责任公司中板厂11辊矫直机支承辊和工作辊轴承原采用干油集中润滑,由于现场条件恶劣,受高温、冷却水和氧化铁皮的影响,干油集中润滑系统无法正常工作,因此只能人工向94个轴承内一次性涂抹干油,中途无法补油。如发生碳化、干结,不但起不到润滑作用,反而会堵塞管道或使支承辊轴承卡死,工作辊表面划伤,影响钢板的矫直和表面质量。 由于润滑不良,该矫直机整个辊系一般只能使用3个月就要更换,一年要换四套辊系,直接费用200多万元。为了解决这一难题,决定
Xinyu Iron and Steel Co., Ltd. 11 mill roll leveling machine roll and work roll bearing the original use of dry oil lubrication, due to poor site conditions, subject to high temperature, cooling water and iron oxide skin, dry oil lubrication system does not work , So only manually to the 94 bearing one-time smear dry oil, midway unable to make oil. Such as carbonization, dry knot, not only failed to play the role of lubrication, but will plug the pipe or support roller bearing stuck, the work roll surface scratches, affecting the straightening and surface quality of steel. Due to poor lubrication, the entire roller straightener can only be used within 3 months to be replaced, one year to change four sets of roller system, the direct cost of more than 200 million. In order to solve this problem, decided
