    摘要： A method for forming a lubricant coat on a surface of steel slug to be forged and a forging device provided with a lubricant coat forming system. The method makes possible the forging of hard to work material, such as stainless steel. Highly durable parts can be manufactured easily. The durability of the metal molds of the forging device is increased, thereby decreasing the cost for the manufacture of the parts. In the method, the uniformly thick lubricant coat can be formed easily even on the transformed end surfaces of the material being worked, providing effective lubrication. The lubricant coat forming member can replace the oil lubrication of the related-art forging device of the inline type, in which the cut end surfaces of the material are not lubricated, without modifying the structure of the related-art forging device especially. The forging device of this invention continuously forges the material, lengthening the interval for replacing metal molds and decreasing the cost for the manufacture of the parts.
