Coil coating production rate

This site coats cold rolled steel and galvanized steel. The data presented are the analyses of the effluent from the cold rolled steel operations. Approximately 11 million m2 of steel material are cleaned, coated and painted annually in the U.S. The plant uses water at a rate of 1.2 L/m2 of product and produces 1630 m2/h of coated steel coil. 

The converter will operate most efficiently when it supplies coating binder at the same rate as it is consumed. Problems may occur when the converter has to be shut off and flushed with water. Channel flow and vortices during the purge with water affect cleaning time and may make it necessary to sewer starch product. In another converter, a single pump is used to transport the starch through the retention vessel. Jet cookers of the venturi type are placed at the entrance to the vessel and at its exit.114 In an alternative design, a retention coil is used instead of a retention vessel.115...
