鋼板のスプレー塗装方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention is a steel plate manufactured by a thick plate mill or a hot strip mill, in which only the central part of the upper surface of the steel plate is coated, and a non-sprayed part is formed at the edge of the upper surface of the steel plate. It relates to a spray painting method.

なものであり、またオーバー塗布による塗料ロス
も大きいものである。 When a user welds or gas-cuts a steel plate on the surface or both sides of the steel plate, the burning of the paint causes a deterioration of the working environment and a decline in quality during welding. Attempts have been made not to pre-apply paint to the area to be cut. The conventional method is to attach paper tape, cloth tape, etc. to the part of the steel plate corresponding to the gas cutting part or the welding part before painting the steel plate, and then peeling off the tape after painting to attach the unpainted part to the surface or front and back of the steel plate. It formed the This method is commonly known as the blind method, and creates a clean unpainted boundary line, but it requires adhering one piece of tape to a predetermined position on a large number of medium-thickness steel plates that are to be painted. The amount of tape adhesion work and tape peeling work is large, and paint loss due to overcoating is also large.

た。 Therefore, the present inventors have repeatedly devised a method for applying edge painting without performing tape adhesion work, and have discovered that it is possible to form non-painted areas on the surface of a steel plate or on the edges of the front and back surfaces using only a spray painting method.

ー塗装方法。 The gist of the present invention is as follows: (1) A pair of left and right steel plate edge coating spray guns, which can be positioned in accordance with the width of the medium-thickness steel plate to be coated, are used to spray a uniform width of a uniform width on the top surface of both ends of the steel plate to be coated. The top surface of the steel plate is painted vertically, leaving the painted area, and in combination with this, the unpainted area at the center of the top surface of the steel plate that cannot be painted with the steel plate edge coating spray gun is painted with a horizontal spray gun that moves back and forth in the width direction of the steel plate. A unique spray painting method for medium-thick steel plates.

法。(2) A spray gun that runs along a guide rail that is inclined with respect to the width direction of the medium-thickness steel plate to be coated is used to spray a certain width of uncoated area on the top surface of the leading edge or the top surface of the rear edge of the steel plate to be coated. At the same time, use a pair of left and right steel plate edge coating spray guns that can be positioned according to the width of the painted steel plate to vertically paint the top surface of the steel plate, leaving a certain width of unpainted area on the top surface of both ends of the plate width. This spray coating method for a medium-thickness steel plate is characterized in that the unpainted part at the center of the upper surface of the steel plate that cannot be coated with the edge coating spray gun is coated with a transverse spray gun that reciprocates in the width direction of the plate.

Nozzle 6 is a single-hole nozzle (chip spray pattern 22, 22') that is normally used as a shot primer, and the tip of the nozzle is attached to a steel plate in order to show the boundary line with the unpainted area. The angle of inclination θ1 toward the center of the plane was set at 10 to 30°. Three guide rails 11, 12, 13 to which the transverse spray guns 8, 8a, 9, 9a, 10 are attached are arranged at equal intervals from each other, and the transverse spray guns 8, 8a, 9, 9a, 10 is 10, 9a, 9, 8 from the previous stage according to the progress of the tip of the plate feeding steel plate.
If five spray guns are employed at the same time as in this example, where spray guns are gradually increased in the order of a and 8, the coating trajectory of spray gun 8 will be the part shown in Fig. 1, and the coating trajectory of spray gun 8a will be as follows. The spray gun tip size, spray gun traverse speed, etc. are adjusted so that the spray gun 9a's coating trajectory is the same as the normal spray gun tip size, spray gun traverse speed, etc. I did the horizontal painting work.

When point F of the steel plate shown in Fig. 2, which is the spray start point, reaches the spray gun's placement point 17, the spray gun 17 starts spraying and moves to the right side, following the progress of the steel plate as shown in Fig. 2. Paint the tip part J of the steel plate shown in . After painting the steel plate up to point G, the spray gun 17 stops and returns to its original position on the left side to wait in order to paint the next steel plate.

A pair of left and right steel plate edge coating spray guns that can be positioned in accordance with the width of the medium-thickness steel plate to be coated are used to spray a certain width of unpainted area on the upper surface of both ends of the steel plate to be coated. The method is characterized in that the upper surface of the steel plate is painted vertically, leaving a vertical coating, and in combination with this, the unpainted part at the center of the upper surface of the steel plate, which cannot be painted with the spray gun for edge coating of the steel plate, is painted with a horizontal spray gun that moves back and forth in the width direction of the steel plate. How to spray paint thick and medium steel plates. 2 A spray gun that runs along a guide rail that is inclined with respect to the width direction of the medium-thickness steel plate to be coated is used to leave an uncoated area of a certain width on the top surface of the leading edge or the top surface of the rear edge of the steel plate to be coated. While performing spray painting, a pair of left and right steel plate edge coating spray guns whose positions can be set according to the width of the coated steel plate are used to vertically paint the top surface of the steel plate, leaving an unpainted area of a certain width on the top surface of both ends of the plate width, In combination with this, the method for spray painting a medium-thickness steel plate is characterized in that the unpainted part at the center of the upper surface of the steel plate that cannot be painted with the edge coating spray gun is coated with a transverse spray gun that moves back and forth in the width direction of the plate.
