PURPOSE:To cool extruded products efficiently and remove remaining stress effectively, by furnishing a cooling roller conveyer in which are arranged cooling rollers with an inner circulating coolant, just behind the extruding portion of an extruding machine. CONSTITUTION:In a system to convey high temperature extruded products W extruded from an extruding machine 1 to the next process, while cooling gradually, is arranged a cooling roller conveyer 6 in which cooling rollers 10 housing an inner circulating coolant such as water, just behind the extruding portion 3 of the extruding machine 1. As a result, the extruded products extruded from the machine can be cooled efficiently, and the remaining stress is removed effectively, as well as extruded products with a stable and high accuracy can be obtained with no deformation after cooling.
