环保型冷轧硅钢乳化液的研制及其摩擦学性能研究

DEVELOPMENT OF ENVIRONMENTALLY FRIENDLY EMULSION FOR COLD-ROLLED SILICON STEEL AND ITS TRIBOLOGICAL PROPERTIES

采用环保型基础油和添加剂研制一种环保型高润滑性能冷轧硅钢乳化液,对其摩擦学性能和润滑性能进行考察,并与KD型商用乳化液的性能进行对比。结果表明,与KD型商用乳化液相比,环保型乳化液的摩擦学性能明显提高,环保型乳化液润滑下冷轧硅钢板的最小可轧厚度降低了13.3%,轧后板形及硅钢表面质量也更为理想,同时,环保型乳化液还具有良好的退火清净性。综合分析可知,环保型乳化液更适合在高速冷轧硅钢生产中使用。

Enviromentally friendly silicon steel rolling emulsion with high lubricating property was developed using environmentally friendly base oil and additives. The lubricating performance was ana- lyzed by MRS-10A four-ball tester and 4-high cold-rolling mil and compared with the KD traditional emulsion. The results show that relative to the traditional KD emulsion, the developed cold-rolling emulsion shows a higher lubricating performance, a better annealing cleanliness, and that the minimum rolling thickness is decreased by 13.3%. After rolling, silicon steel strip shape and surface quality is more ideal. It is concluded that the developed enviromental emulsion can meet the need of the high speed silicon steel cold- rolling process.
