釬子鋼是鑛山生产上主要的消耗材料,它的製成品是一種重要的工具。釬子質量的好坏,直接影響着生产效率的提高和成本的降低。本刊過去曾刊载過幾篇有關提高釬子質量的文章,現在又發表周松年同志這篇譯稿。希望各鑛在改進釬子的問題上,一方面吸取其他鑛山的先進經驗;另一方面從理论上来研究釬子鋼在鍛冶与淬火過程中内部組織的變化,並研究根據這種變化所必须注意的操作方法,這樣才能更进一步地改進我们的釬子質量。
Bauxite is the major consumable material in mine production and its finished product is an important tool. The quality of the solder is good or bad, directly affecting the production efficiency and cost reduction. In the past, we have published several articles on improving the quality of brazing rods, and we now publish the translation of this work by Comrade Zhou Songnian. Hope that the mine on the issue of improving the brazing alloy, on the one hand to learn from the advanced experience of other mines; the other hand, from a theoretical study of the brazing steel in the process of forging and quenching changes in the internal organization and to study according to this change must Attention to the operation method, so as to further improve the quality of our solder.
