耐久磁鋼材料,在各種發動機的發火設備,電話機,無線電喇叭,傳話器以及各種電表儀器的製造中。都是亟不可缺的。過去國內此項材料的供應,都仰給於外來。在全國革命解放事業的順利發展下,各地舊有的設施須由破壞而恢復,而更進而發展與建設,處處需用此類材料甚多,需要設法自製來解決困難。雖然耐久磁鋼的臻善製造,由於我國冶煉工業的尚未成熟,並限於設備、原料及參攷資料的缺乏,困難尚未完全克服;但是向着這方向求自力更生的努力是值得重視和鼓勵的,這里是一位實際工作者的研究記錄,我們樂意將它介紹給讀者,來引起更大的迴響。 Durable magnetic steel materials are used in the manufacture of various engine ignition devices, telephones, radio horns, microphones, and various metering instruments. All are essential. In the past, the supply of this material in the country was given to foreigners. Under the smooth development of the country’s revolutionary liberation cause, the old facilities in various parts of the country must be restored through destruction, and further development and construction are needed. There are many such materials that need to be used everywhere, and it is necessary to find ways to solve difficulties by self-control. Although the use of durable magnetic steel, due to China’s smelting industry is not yet mature, and limited to the lack of equipment, raw materials and reference materials, the difficulties have not been completely overcome; but efforts to seek self-reliance in this direction is worthy of consideration and encouragement. It is a research record of a real worker. We are happy to introduce it to readers to cause more repercussions.
