High quality basic oil for aluminum alloy rolling obtained from lubricant byproduct

Hydroisomerizing-dewaxed lubricant byproduct contains low sulfur and aromatic hydrocarbon.After rectification of the hydroisomerizing-dewaxed lubricant,its byproduct gets low pour-point,high viscosity,low sulfure and aromatic hydrocarbon and high oxidation stability.The third generation of aluminum rolling basic oil being produced in this way.The production process of the basic oil is simple.The oil quality is high.The production cost is low and economic efficiency is high.
