果を奏する。As described above, the present invention relates to a method of forming a solid-type aluminum extruded shape having an opening extending longitudinally on one side. A bolster having a space through which the profile passes is arranged, and a pair of rollers for guiding both side edges of the opening of the extruded aluminum profile immediately after extrusion are arranged at predetermined intervals in the space of the bolster. Immediately after hot extrusion by a die, both sides of the opening of the aluminum extruded profile are guided by a pair of straightening rollers in the bolster space, so that the inner dimensions between the two sides of the opening are both straightened. The width of the roller is corrected to a width equal to the arrangement interval between the outer sides, and at the same time, the cross-sectional shape is corrected. In addition, it is possible to manufacture a high-quality aluminum extruded member having extremely high dimensional accuracy, having a tolerance of a cross-sectional dimension within a range of, for example, 1/4 to 1/2 of a special grade specified in JIS standard H4100. The straightening of the extruded aluminum member can be performed on the production line of the extruded member, which does not require the conventional off-line roll straightening step for the extruded member, and thus the aluminum extruded member can be extruded. The effect is that the production cost of the material can be reduced.
