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 inclusion of titanium in the cord steel, both w (Ti) and w (N) in the molten steel should be reduced. Through controlling the w (Ti) in the molten steel by using low titanium alloy, optimizing the tapping process of the converter and controlling the amount of slag under the converter, the W (N) in the molten steel is reduced by adopting low- ). Practice shows that: when w (Ti) is controlled not more than 0.0004% and w (N) is not more than 0.004%, the precipitation of titanium inclusions can be significantly reduced or even eliminated.
