铝卷生产厂家加强轧制油质量的控制方法
Control methods for aluminum coil manufacturers to strengthen the quality of rolling oil
一、轧制油配比
1、 Rolling oil ratio
铝冷轧轧制油由基础油添加I%一10%添加剂混合组成。基础油与添加剂要求有较好的相容性，在使用中不易生成油泥而降低润滑冷却效果和使用安全性。结合实际生产情况，目前我公司采用MOA-100基础油与WYROL12添加剂，添加剂含量控制在6.8%-7.3%,粘度2. 5cSt -2.6cSt，污染度3级以内，馏程230℃一280℃，残馏3%以内。
Aluminum cold rolling oil is composed of base oil and I% - 10% additive. The base oil and additives are required to have good compatibility. It is not easy to generate oil sludge in use, which will reduce the lubrication and cooling effect and use safety. Combined with the actual production situation, at present, our company adopts moa-100 base oil and wyrol12 additive, the additive content is controlled at 6.8% - 7.3% and the viscosity is 2.5% 5cst - 2.6cst, pollution degree within grade 3, distillation range 230 ℃ - 280 ℃, residual distillation within 3%.

轧制油使用中要避免设备润滑油、液压油等重油混进轧制油里，造成粘度增高，除油困难。如已经混人过多重油并经分析化验轧制油粘度过高时应及时更新轧制油。
During the use of rolling oil, heavy oil such as equipment lubricating oil and hydraulic oil shall not be mixed into the rolling oil, resulting in increased viscosity and difficult oil removal. If too much heavy oil has been mixed and the viscosity of rolling oil is too high through analysis and test, the rolling oil shall be updated in time.
二、轧制油过滤
2、 Rolling oil filtration
冷轧时轧件与轧辊摩擦，不断磨下细铝粉，使轧制油循环系统的铝粉含量愈来愈多，轧制油的润滑性能随之降低，铝粉又易粘在板带表面上，恶化了板带表面质量。为了延长轧制油使用期限和提高板材表面质量，在加工过程中对轧制油必须进行过滤。
During cold rolling, the rolled piece rubs with the roll and continuously grinds down the fine aluminum powder, which makes the aluminum powder content of the rolling oil circulation system more and more, and the lubrication performance of the rolling oil decreases. The aluminum powder is easy to stick to the surface of the strip, deteriorating the surface quality of the strip. In order to prolong the service life of rolling oil and improve the surface quality of plate, the rolling oil must be filtered in the processing process.
目前主要使用板式过滤器，把过滤介质硅藻土、活性白土和轧制油混合后，予涂在过滤纸上，过滤器有二垛，每垛过滤纸为10层。由容积过滤介质和多层过滤纸形成容积过滤装置，脏轧制油通过它达到精过滤的要求。板式过滤器工作压力达到3喃/c扩时必须重新更换过滤纸。板式过滤器过滤精度达0.55m，过滤能力32001/min.
At present, plate filters are mainly used. After mixing the filter media diatomite, activated clay and rolling oil, they are coated on the filter paper. There are two stacks of filters, and each stack of filter paper has 10 layers. The volume filter device is formed by the volume filter medium and multi-layer filter paper, through which the dirty rolling oil meets the requirements of fine filtration. When the working pressure of the plate filter reaches 3 N / C, the filter paper must be replaced again. The plate filter has a filtering accuracy of 0.55M and a filtering capacity of 32001 / min
为了保证过滤效果，硅藻土与活性白土的比例一般为2:1，在过滤过程中，通过混合箱不断向脏轧制油中均匀加人过滤介质，以稳定过滤效果和延长过滤周期。
In order to ensure the filtration effect, the ratio of diatomite to activated clay is generally 2:1. In the filtration process, the filter medium is continuously added to the dirty rolling oil through the mixing box to stabilize the filtration effect and prolong the filtration cycle.
