摘　　要：TiN夹杂是影响帘线钢等高碳钢类产品疲劳寿命的一个重要因素,而TiN的数量以及级别随钢中钛含量的增高而增高,因此钛含量的控制是高碳钢生产的主要任务之一。分析了高碳钢钛含量的控制措施,采用转炉双联法冶炼进行深脱钛,同时结合炉后扒渣,采用低钛合金、低钛脱氧剂等工艺措施,将钢中的钛含量控制在10×10-6及以下。TiN inclusion is an important factor affecting the fatigue life of high carbon steel products such as cord steel,the amount and grade of TiN increase with the increase of titanium content in steel,thus TiN inclusion is an important factor affecting the fatigue life of high carbon steel products such as cord steel.The quantity and grade of TiN increase with the increase of titanium content in steel,so the control of titanium content is one of the main tasks of high carbon steel production.In this paper,the control measures of titanium content in high carbon steel are analyzed,and the titanium content in steel is controlled at 10×10-6 or below by means of deep detitanization combined with slag removal and silica-manganese deoxidation after furnace and low titanium alloy.
