Abstract:Focusing on the effects of oxidation heattreatment of the Φ167 specification piercing plug of Φ159mm crew in Baotou Iron and Steel(Group)Co., the heat treatment equipment, oxidation heat treatment temperature and oxidation time werestudied experimentally. The thickness and quality of the oxide film ofthe piercing plug can be improved significantly when the oxidation heattreatment temperature is 980℃ and the oxidation time is 4 hours by using the new pit type furnace. The service life of the piercing plug canbe improved on the rolling mill, and the costs can be reduced ，with the competitiveness of the products enhancedin this way.
