一种复吹转炉耐火材料内衬烘烤的方法
摘要：
本发明涉及一种复吹转炉耐火材料内衬烘烤方法，它是离线将复吹转炉耐火材料内衬砌筑完后，在砌筑位将天然气和氧气通入顶枪，点燃顶枪，先用顶枪烘烤，待耐火材料内衬温度达到350～400℃时，再将天然气和空气通入底枪，采用顶枪和底枪复吹方式进行烘烤，当耐火材料内衬温度达到1050～1200℃时，关闭燃气阀门与空气阀门停止烧烤。本复吹转炉耐火材料内衬烘烤的方法可在复吹转炉冶炼生产的同时，同步对另一个新砌复吹转炉耐火材料内衬进行离线烘烤，从而提高复吹转炉的产能。
摘要（英）：

The invention relates to a method for baking a refractory material lining of a combined blown converter. The method comprises the following steps of: building the refractory material lining of the combined blown converter offline; introducing natural gas and oxygen into a top gun at a building position; igniting the top gun; baking by using the top gun; after the temperature of the refractory material lining is between 350 and 400 DEG C, introducing natural gas and air into a bottom gun; baking by using the top gun and the bottom gun in a combined blown mode; and when the temperature of the refractory material lining is between 1,050 and 1,200 DEG C, closing a gas valve and an air valve so as to stop baking. In the method for baking the refractory material lining of the combined blown converter, the refractory material lining of another newly-built combined blown converter can be baked offline when smelting production is performed by the combined blown converter, so that the productivity of the combined blown converter is increased.
