Information × Registration Number 0308U003578, 0108U004703 , R & D reports Title Advancement of the technology for manufacturing cast iron grinding bodies, mastering of the new possibilities of their application. popup.stage_title Удосконалення технології виготовлення литих чавунних молольних тіл, освоєння нових можливостей їх використання Head Vladimirova Albina Aleksandrovna, Registration Date 13-05-2008 Organization Ukrainian State Scientific and Engineering Center "Energostal" popup.description2 Influence of process parameters and their limits on operating performances of grinding bodies was determined. For grinding bodies from non-alloy iron carbon content is to make 2.8-3.2 %, silicon - up to 1 %, melt temperature is 1440-1460 °С, casting temperature is 1340-1350 °С, that in combination with cooling mode provide hardness no less than 46 HRC under the guaranteed crash-worthiness. For cylinders from economically chrome-doped iron (up to 3 %) carbon content is 2.7-3.1 %, silicon up to 1 %, melt temperature is 1490-1510 °С, casting temperature - 1380-1400 °С. The guaranteed hardness is 48-53 HRC. Technique and criterion to assess grinding body crash-worthiness were developed. Specifications on manufacturing grinding bodies and production schedule were developed and put into action.56355635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
