鋁卷生產(chǎn)廠(chǎng)家加強(qiáng)軋制油質(zhì)量的控制方法
Control methods for aluminum coil manufacturers to strengthen the quality of rolling oil
一、軋制油配比
1、 Rolling oil ratio
鋁冷軋軋制油由基礎(chǔ)油添加I%一10%添加劑混合組成。基礎(chǔ)油與添加劑要求有較好的相容性，在使用中不易生成油泥而降低潤(rùn)滑冷卻效果和使用安全性。結(jié)合實(shí)際生產(chǎn)情況，目前我公司采用MOA-100基礎(chǔ)油與WYROL12添加劑，添加劑含量控制在6.8%-7.3%,粘度2. 5cSt -2.6cSt，污染度3級(jí)以?xún)?nèi)，餾程230℃一280℃，殘餾3%以?xún)?nèi)。
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%.

軋制油使用中要避免設(shè)備潤(rùn)滑油、液壓油等重油混進(jìn)軋制油里，造成粘度增高，除油困難。如已經(jīng)混人過(guò)多重油并經(jīng)分析化驗(yàn)軋制油粘度過(guò)高時(shí)應(yīng)及時(shí)更新軋制油。
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、軋制油過(guò)濾
2、 Rolling oil filtration
冷軋時(shí)軋件與軋輥摩擦，不斷磨下細(xì)鋁粉，使軋制油循環(huán)系統(tǒng)的鋁粉含量愈來(lái)愈多，軋制油的潤(rùn)滑性能隨之降低，鋁粉又易粘在板帶表面上，惡化了板帶表面質(zhì)量。為了延長(zhǎng)軋制油使用期限和提高板材表面質(zhì)量，在加工過(guò)程中對(duì)軋制油必須進(jìn)行過(guò)濾。
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.
目前主要使用板式過(guò)濾器，把過(guò)濾介質(zhì)硅藻土、活性白土和軋制油混合后，予涂在過(guò)濾紙上，過(guò)濾器有二垛，每垛過(guò)濾紙為10層。由容積過(guò)濾介質(zhì)和多層過(guò)濾紙形成容積過(guò)濾裝置，臟軋制油通過(guò)它達(dá)到精過(guò)濾的要求。板式過(guò)濾器工作壓力達(dá)到3喃/c擴(kuò)時(shí)必須重新更換過(guò)濾紙。板式過(guò)濾器過(guò)濾精度達(dá)0.55m，過(guò)濾能力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
為了保證過(guò)濾效果，硅藻土與活性白土的比例一般為2:1，在過(guò)濾過(guò)程中，通過(guò)混合箱不斷向臟軋制油中均勻加人過(guò)濾介質(zhì)，以穩(wěn)定過(guò)濾效果和延長(zhǎng)過(guò)濾周期。
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.
