为稳定铝镇静钢中的包钙含量, 进行了复合钙铝包芯线钙处理生产实践.结果表明:与钙铁线相比, 在钢水量相近且喂线量相当的情况下, 采用复合钙铝包芯线进行钙处理, 中包钙含量稳定性较好, 中包钙含量波动在0. 000 1％～0. 000 2％之间;实际最高可节约钙处理成本约6. 00元/t;同时, 采用复合钙铝包芯线所形成的工艺技术能够在不改动原有喂线设备的条件下进行正常的喂线操作.%In order to stabilize the calcium content of the aluminium-killed steel in the tundish, the production practice of the calcium treatment by using the Ca-Al packed wire is conducted. The results show that the stability of calcium content of the Al-killed steel in the tundish is better after calcium treatment by using the Ca-Al packed wire, in the case of similar amount of steel and wire feeding, compared to the Ca-Fe cored wire. And the cost savings of the calcium treatment can be able to reach 6 per ton. At the same time, the wire feeding operation can be also on the rails by using the process technology formed from the calcium treatment by the Ca-Al packed wire, under the condition that the original wire feeding equipment is not changed.
