优润(u.lube)连铸机轴承润滑脂经受长期高温考验，保障炼钢厂正常生产
u.lube continuous caster bearing grease withstands long-term high temperature test to ensure normal production of steel plant
连铸机是炼钢厂用来制造钢坯的机器，它可以通过熔融和浇铸来制造出不同种类的钢坯。连铸机轴承需要持续定期润滑，以确保轴承正常运行，减少磨损，提高轴承寿命。但是因连铸机轴承长期承受了钢坯近千度的高温烘烤以及水汽、粉尘的影响，轴承很容易出现油脂结焦积碳，润滑管路堵塞，轴承缺油失效的现象，严重影响到生产。
continuous caster is used in steel plant to manufacture billets by melting and casting to produce different types of steel. continuous caster bearings need continuous and regular lubrication to ensure proper operation of the bearings, reduce wear and improve bearing life. however, because the bearings of the continuous caster have been subjected to the high temperature baking of billets at nearly 1,000 degrees for a long time as well as the influence of water vapor and dust, the bearings are prone to grease coking and carbon accumulation, lubrication line blockage and bearing oil shortage failure, which seriously affects the production.
因此，炼钢厂要保障生产正常运转，连铸机对于润滑比较高，需要专用润滑剂才能满足连铸机长期高温、水汽、粉尘的工况下的润滑。去年优润(u.lube)服务团队与国内某炼钢厂进行合作，选取某段连铸机进行为期3个月的上机测试优润(u.lube)连铸机轴承润滑脂 et uplex cg ，经过这3个月的测试（至今仍在使用），润滑脂的各项性能参数均达到炼钢厂技术协议要求，满足现场使用，保障炼钢厂生产运转，也得到炼钢厂设备管理部的认可。
therefore, in order to ensure the normal operation of the steel plant, the continuous caster has a high demand for lubrication and needs special lubricants to meet the lubrication of the continuous caster under the long-term high temperature, water vapor and dust conditions. last year, u.lube service team cooperated with a domestic steel plant and selected a section of continuous caster for 3 months to test u.lube continuous caster bearing grease et uplex cg, after these 3 months of testing (still in use), the performance parameters of the grease meet the requirements of the technical agreement of the steel plant, to meet the use of the site, to ensure the production of the steel mill it is also recognized by the equipment management department of the steel plant.
此次的测试效果主要有以下几点：
the main effects of this test are the followed:
1、 使用中润滑脂的铁含量低。
1、 the iron content of grease in use is low.
根据3份不同时间的采样进行检测的结果，经过计算得出优润(u.lube)润滑脂采样品中铁平均含量为201ppm，小于试用技术协议要求的1000ppm（检测方法为：astmd7303-17）。
according to the test results of 3 different time samples, the average iron content of u.lube grease sample is 201ppm, which is less than the 1000ppm required by the trial technical agreement (test method: astmd7303-17).
2、 轴承无损伤。
2、 no damage to the bearings.
测试期间，轴承无损坏；测试结束时，轴承外观无明显变化。
no damage to the bearings during the test; no significant changed in the appearance of the bearings at the end of the test.
3、 管道正常工作。
3、 the pipeline works normally.
测试期间管路未出现大面积堵塞现象（5%以上）。
no large blockage (more than 5%) in the pipeline during the test.
4、 轴承润滑脂良好。
4、 the bearing grease is good.
测试期间轴承内润滑脂未出现硬化、干裂、流失等润滑不良现象。
during the test period, the grease in the bearing did not appear hardening, dry cracking, loss and other poor lubrication phenomenon.
