TUBE MILL PROCESS CHEMICALS

摘要

Coolants are used to wash oils, oxides, slivers, dirt and heat generated in the process of forming, welding, sizing and cutting of welded tubes and shapes. Typical applications of these coolants include pre and post punch, cold roll forming, weld zone flushing, impeder rod cooling, weld scarf removal, profile cooling, sizing, and saw-type cut-off. These coolants begin as a mixture of water and refined chemicals that help cleanse the process, protect part finish, extend tool life, and inhibit rust and corrosion on the profile and machine. This high volume low pressure continuous flow of water and chemicals over the tools and work piece results in the build up of impurities, such as sludge and oil that must be removed. If not removed, these contaminants quickly build up and can cause deleterious effects in the profile production, storage, fabrication and finishing processes; these same contaminants are also known to injure machine moving machine components such as bearings, ways, pumps and cylinders. Therefore, these contaminants must be removed at some point using strainers, filters, skimmers, and other mechanical methods.
