摘　　要：为了控制帘线钢中的钛夹杂,要同时降低钢水中的w(Ti)及w(N)。通过采用低钛合金、优化转炉出钢工艺、控制转炉下渣量等措施控制钢水中的w(Ti);采用低氮增碳剂,优化全工序降氮操作等措施降低钢水中的w(N)。实践表明:当钢中w(Ti)控制在不大于0.000 4%,w(N)控制在不大于0.004%时,能显著降低甚至杜绝钛夹杂的析出。In order to control the titanium inclusions in tire cord steel, vo（Ti） and zv（N） in steel should be reduced. To control zv （Ti） in steel technological measures such as low - titanium alloy was used, converter tapping process was optimized and slag amount in converter was controlled. To reduce w（N） in steel low nitrogen carburant was used, nitrogen controlling in the whole process was optimized. Practice results showed that titanium inclusions could be obviously reduced when w（Ti） ≤0. 000 4% and zv（N）≤0. 004%.In order to control the titanium inclusions in tire cord steel, vo（Ti） and zv（N） in steel should be reduced.
