摘要: Following the discharge of steel from a steel producing converter, the adding and inclusion of nitrogen is impeded by surrounding the stream of pouring steel with a layer of limestone at a grain size not exceeding 5 mm. Practice has shown that the nitrogen content can well remain below a content of 0.005%.
