自从本刊1962年第4期刊登徐惠铨同志的“炉前检验铁水时圆形试棒的使用”一文以后,曾引起顾寿生与郭庭双两同志对这篇文章从理论上提出不同的看法,后来原作者又从理论上对顾、郭两同志的不同看法作了解释(详见本刊1962年第7、11两期)。实际上,圆形试棒的变化要从理论上来说明问题,必须要做大量的试验研究工作。我厂对于这方面的试验研究工作做得并不太多,如果再从理论上来讨论,可能依然不能得到满意的解释。因此,我想根据圆形试棒的尺寸及其
Ever since Comrade Xu Hui Quan published the article “The use of round test sticks for testing hot metal in front of furnaces” published in the fourth issue of 1962, he has given rise to the different opinions put forward by Gu Shousheng and Guo Tingguang and his colleagues in theory. Later, In addition, the author explains theoretically the different views of Gu and Comrade Guo (see Articles 7 and 11 of 1962). In fact, the change of the round test stick should explain the problem theoretically, and a large amount of experimental research work must be done. Our factory did not do too much for the experimental research in this field. If we discuss it theoretically, we may still not be able to get a satisfactory explanation. Therefore, I think according to the size of the circular test rod and its
