在制造255立方公尺高爐铁渣車任务中,因横梁为25铸钢,長度达4550公厘,最小断面为200×400公厘,而我厂只有0.25砘电弧爐,最大能力一次只能浇铸400公斤,翻砂車間解决不了。在这种情况下,我們用电渣焊方法采取以小拼大来制造該部件。经过多次創造性的实驗,利用0.25吨电弧爐变压器充当电渣焊变压器,成功地焊成了鈇渣車横梁,解决了生产关键。利用0.25吨电弧爐三相变压器充当电渣焊变压器,
In the manufacture of 255 cubic meters of blast furnace iron slag truck task, due to the beam of 25 cast steel, length of 4550 mm, the minimum section of 200 × 400 mm, and I plant only 0.25 砘 electric arc furnace, the maximum capacity of only casting 400 kg, turning the sand workshop can not solve. In this case, we use the electroslag welding method to make the part with small enlargement. After many creative experiments, the use of 0.25 tons of arc furnace transformer as electroslag welding transformer, successfully welded into the slag car beams, to solve the production of the key. Use 0.25 tons arc furnace three-phase transformer as electroslag welding transformer,
