Zusammenfassung:	PROBLEM TO BE SOLVED: To supply lubricant to the boundary between a die and steel always and smoothly by preventing that large lumps of the lubricant are formed in the neighborhood of a drawing part. SOLUTION: In a steel drawing apparatus in which a die 1 is provided on one side of a box 2 filled with powdery lubricant 3 and wire drawing is performed by depositing the lubricant on the surface of the steel by passing the steel 4 through the inside of the box and the die, moving blades 5 surrounding the steel 4 are arranged inside the box 2 so as to be concentric with the steel, the tip part 5a of the moving blade is made to face the inside surface of the die and also a driving means 11 for rotationally moving the moving blades is provided. The moving blades 5 are formed by fixing a plurality of blade members 6 having a curved-plate shape curved in one direction in the inner edge part of a movable ring 7 at fixed intervals and the tip part 5a of each blade member is formed to be acute.
