- TITLE: THE DETERMINATION OF THE CAUSES FOR PREMATURE RELEASE FROM THE ARRAY OF CAST CYLPEBS MADE FROM WHITE HIGH CHROMOUS CAST IRON AND THEIR SUBSEQUENT THERMAL TREATMENT
- ABSTRACT: This article discusses the causes of premature failure of the drum cast cylpebs made of a white high chrome cast iron LLC «Dalvarzinsky repair factory». Theoretical and practical basics of preparation and receipt of cylpebs by casting in earthen form were observed. In the article is presented the best option of the chemical composition of cast iron ICHH28N2 brand and its mechanical properties-hardness of iron, optimal thermal treatment with a double phase recrystallization for cast cylpebs are presented. The composition and properties of the iron before and after heat treatment are studied. The final heat treatment mode, increasing hardness and wear resistance of cast cylpebs in two or more times are proposed.
