PURPOSE: A square bar dryer of a square bar coating apparatus is provided to remove moisture on the surface of a square bar before the square bar undergoes an extruder for applying a coating agent thereon. CONSTITUTION: A lower frame(110) is fixed to a die by a screw or a bolt and nut(111). Upper and lower heating plates(130,120) have a heater embedded therein, are made of a heat transfer material, are located above the lower frame(110), are formed at a height where a square bar is easy to proceed at the pre-stage of a square bar coating apparatus to the next stage thereof and are spaced at an interval as much as the vertical width of the square bar(1). An upper frame(140) is formed above the lower heating plate. A connecting rod is formed on the peripheries of the four corners of the lower frame(110) and is fixed to the upper frame(140) via the upper and lower heating plates(130,120). |
