钢鑄件的生产中冷铁的需要量很大,自从学习苏联基洛夫工厂的用钢切屑作內冷铁的經驗后,一年来的实踐証明,不仅对鑄件的質量有所提高,同时节約了很多鋼材。今将使用的經驗介紹給大家参考。切削规格用切削加工出来的成卷的鋼切屑(如图1)代替螺旋形內冷铁时,要求切屑沒生銹、不含水分、沒沾染油垢,或是水分和油垢不多。切屑的厚度一般在0.5～2公厘,圈与圈
The demand for chilled iron in the production of steel castings is very high. After learning the experience of using chipping steel for internal chill iron in the Kirov factory in the Soviet Union, the practice over the past year has proved that not only the quality of the castings has been improved, but also the festival About a lot of steel. The experience we will use to introduce for your reference. Cutting Specifications A cut steel coil (Fig. 1), which is cut out of steel to replace the spiral inner chill iron, requires that the chips do not rust, contain moisture, do not contaminate the grease, or have little water and grease. Chip thickness is generally 0.5 to 2 mm, circle and circle
