<p>PURPOSE:To control the generation of resin blister and obtain stabilized plate thickness by heating a resin layer with far infrared rays before placing the resin layer between two steel plates, heating and fixing by pressure. CONSTITUTION:In the manufacturing method of a composite steel plate including the process of clamping a resin layer between two steel plates, heating and fixing by pressure, the resin layer is heat dried preliminarily by means of far infrared rays before placing the resin layer between the steel plates. The water content in the resin is removed quickly with extremely good efficiency and blister is controlled irrespective of environmental temperature, humidity, kind of resin or the like by said process. The uneven distribution of plate thickness of a product, therefore, is prevented and a composite steel plate of stabilized product thickness can be manufactured.</p> |
