The manufacturing method of coated steel sheet(1) comprises a step of forming an alloy coating layer(3) by plating a substrate steel sheet(2); a step of forming a chromate layer(4) of 15 to 45 mg/m¬2 by drying the chromate coated on the alloy coating layer at a temperature of 80 to 120 deg.C after roll coating chromate on the alloy coating layer; a step of forming a primer coating layer(5) of 4 to 8 μm by drying the paint coated on the chromate layer at a temperature of 216 to 224 deg.C after roll coating a paint containing polyester resin on the chromate layer; and forming an aromatic coating layer(6) by heating thus drying the paint coated on the primer coating layer at a certain temperature after roll coating a paint containing 40 to 80 wt.% of polymer polyester resin, 2 to 15 wt.% of melamine resin and 0.3 to 10 wt.% of aromatic particles containing materials for emitting incense on the primer coating layer.

Abstract: PURPOSE: To highly precisely maximize shot injection impact quantity using the smallest consumed energy possible. CONSTITUTION: The maximum shot injection impact quantity to a product is computed based on data for maximizing shot injection impact quantity in specified shot injection conditions predetermined, and processing conditions. Shots are injected based on result of computation, and the shot injection impact quantity is measured by a peening strength measuring device. Pressure or flow of compression air and shot supply quantity are corrected to maximize the shot injection impact quantity in accordance with data based on the measured shot injection impact quantity. Shots are injected based on corrected conditions, and a process of measuring the shot injection impact quantity by the peening strength measuring device to a process of injecting shots based on the corrected injection conditions are repeated.
