Rolling oil and additives include filter soil and grinding wheels. Although there is a lot of conceptual hype, rolling oil is still refined kerosene, and the additives are nothing more than acids, esters, and alcohols. Grinding wheel No. 80-800, white corundum, silicon carbide. If we have to find a point of improvement, it is that the quality of these materials is more stable. The process requires more precision. More attention is paid to the quality of the surface and the accuracy of the performance indicators. More precise and stable control of various factors to produce aluminum foil with more precise and stable performance is the difference between today's aluminum foil production and the previous 20 years.
In recent years, wood fiber-fly filter element is gradually replacing diatomite and clay, which is a revolution in filter media. It will exponentially increase the filtration efficiency and reduce the number of harmful substances.
The control of colloid content of rolling oil has become a routine indicator, and stain-free hydraulic oil and lubricating oil have become the basic oils for aluminum foil.
VC rollers, edge heating, rolling oil recovery systems, and fine flow systems are gradually becoming popular.
Pinhole online detection and surface online detection are being promoted.
Aluminum foil production is an extension of aluminum plate production. Most of the experience and theory of aluminum foil production comes from the practice of aluminum plate production. Real aluminum foil production information is rarely seen and is generally kept as the company's technical know-how. This approach directly affected the development of the aluminum foil industry. Those involved in aluminum foil production had only meager design theories or fragmented hearsay from equipment manufacturers. The industry is small and there are few people engaged in aluminum foil research. The aluminum foil production laboratory is unable to conduct research and can only summarize research in production practice. The main purpose of research in production is to solve existing defects and improve. Therefore, breakthrough changes are rare. It should be said that the improvement of aluminum foil production technology in the past century has been synchronized with the level of rolling mill manufacturing and control. Mainly from the increase in speed, the adoption of flatness gauges, VC rollers, the improvement in thickness gauge accuracy, and the possibility of wide-width rolling brought about by the improvement in computer control levels. The basic method of rolling remains unchanged. The viscosity of rolling oil gradually decreases with the increase of rolling speed, and the toxicity gradually decreases with the development of society. The reduction of the thinnest thickness of aluminum foil mainly depends on the improvement of aluminum smelting level.
