我国机械工業的廢切屑总量估計在三十万吨以上。在目前金屬材料極感缺乏的情况下,充分利用廢切屑来弥补金屬材料供应的不足,是很值得我們注意的問題。現在就来談談如何利用廢鋼铁切屑代替鑄铁和廢鋼熔制普通鑄铁和高級鑄铁的問題。我們热誠地希望广大工人同志能够采用各种方法利用廢切屑熔制鑄铁,現在將利用廢鋼铁切屑的几种方法簡要地說明如下: (一)將零散的鋼铁切屑熔制成再生铁后重熔——采用这种方法,一般 The total amount of scrap scrap in China’s machinery industry is estimated at over 300,000 tons. In the current lack of extreme lack of metal materials, the full use of waste chips to make up for the lack of supply of metal materials is a problem that deserves our attention. Now to talk about how to use scrap steel scrap instead of cast iron and scrap melting ordinary cast iron and advanced iron problems. We sincerely hope that the vast majority of workers can use various methods to use waste scrap melting cast iron, scrap iron scrap will now use several methods briefly described as follows: (A) will be fragmented into steel scrap iron after regeneration Remelting - using this method, in general
