薄钢板冷轧轧制油预乳液的研究

Study of Sheet Steel Cold Rolling Pre-Emulsion Oil

在薄钢板冷轧过程中,轧制油的润滑性、退火清净性、冷却性、离水展着性是至关重要的。选择世界一流的奎克公司冷轧轧制油为母油参考指标,以我国现行行业标准为乳液依据,进行预乳液轧制油的研究。首先进行基础油筛选,并对其油性、极压抗磨性、酸性等性能改进;在此基础上进行预乳液研制,着重考察其离水展着等性能。实验证明:以菜籽油为基础油,添加24%左右的高粘物质、1.7%含硫极压抗磨剂、1.3%酸性剂、11%复合乳化剂和3%的消泡剂,所得母油性能完全达到奎克公司薄钢板冷轧油标准,预乳液符合行业使用标准;其5%的乳化液静置24h后析皂量为4.3mL、2%乳化液静置7min后泡沫完全消除;以热重分析模拟退火环境,其油品残留量几乎为0。最终产品符合薄钢板冷轧水基液使用要求。

Developing cold rolling steel sheet pre--emulsion oil in the process of producing cold--rolled sheet, the properties of rolling oil, such as lubrication, cooling , plate--out and anneal free of annoyance, are essential. This study selected a world--class cold rolling oil of Quaker as benchmark for the mother oil, using our current industry standard for the research on pre--emulsion rolling oil. The base oil was selected first, its performance of oil, extreme pressure, anti--wear and acidity were improved. On the basis of the above, the study focused on the development of plate--out. The experiments proved that： using the rapeseed oil as base oil, adding about 24% of the high viscosity material, 1.7% sulfur extreme pressure and anti-- wear agent, 1.3% acidic agent, 11 % complex emulsifier and 3 % of antifoaming agents, the properties of oil reach benchmark of cold rolling oil from Quaker, pre--emulsion oil reaching industry standard. After 24h, 5% emulsion oil separating soap volume is 4. 3mL. 2% emulsion oil the bubbles are completely eliminated in 7min. Using method of thermogravimetric analysis simulating annealing environment, the oil residue is nearly zero. Final products meet requirements of water--based cold--rolled sheet fluid.
