概述了在新钢第二炼钢厂钢包精炼炉中进行喂实芯纯钙线的试验情况.试验结果表明实芯纯钙线的冶金效果和经济效果显著，与喂钙铁线相比：钙的回收率提高11.8%，吨钢钙处理成本降低了3.41元，喂线过程中未出现卡线，断线等异常情况.从理论上推导了实芯钙线速度与钢液重量的关系，通过现场试验和钙处理热力学分析证明：230 t的钢包当喂入外径为9 mm的实芯纯钙线时，最佳喂线速度为2.3 m/s.

The tests on feeding of solid pure-calcium cored wires in refining ladle of the second Converter Plant of Xinyu Iron & Steel Co., Ltd were introduced. The result showed that the average of Ca yield was increased by 11.8%and the Ca treatment cost reduced by 3.14 yuan/t. Wire jamming, disconnecting and other unusual circumstances did not appear in the process of feeding. By field test and thermodynamic analysis, the relationship between the calcium solid core wire speed and the weight of the liquid steel was deduced in theory that when feeding solid core pure calcium wires with external diameter of 9 mm, the best feeding speed for 230 t ladle was 2.3 m/s .
