Abstract
PURPOSE: To prevent powdering phenomenon at the time of working by applying lubricant solution of pH 5,5W8.5 on the surface of an alloyed galvanized steel plate and forming a lubricating film of 0.5W10μ by heating, drying and baking.
CONSTITUTION: An original steel plate 1 from a coil holder 2 is treated in a defatting, reducing annealing furnace 3 and galvanized in a zinc bath 4. The alloyed galvanized steel plate 6 treated in an alloy furnace 5 is chemically treated by a chemical treating device using phosphate, chromate etc. Aqueous solution of acrylic acid polymer is coated on the alloyed galvanized plate 6 thus obtained by a spray 9. Excess solution is squeezed by a squeezing roll 10, and the solution is immediately dried and solidified by a dryer 11. Then, the plate is treated with rust preventing oil and coiled on the coil holder 1 as a product.
