SYNTHESIS AND STUDY OF PHYSICOCHEMICAL PROPERTIES OF CAST IRON WITH FUNCTIONAL PROPERTIES FOR WORKING PART OF BIMETALLIC ROLLING PINS
A new functional cast iron alloyed with transition metals was synthesized for the manufacture of the working part of rolls. Its properties were studied using complex methods of physicochemical analysis (DTA, X-ray, MSA and measurement of hardness and microhardness). It was found that traces of martenicite, cementite, carbon (graphite) and α-ferritin are released in the subsolidus during cooling of molten iron in the studied concentration range (2.7 ÷ 3.5 %wt C. It includes transition metals as an alloying agent increasing resistance of cast iron to twisting, corrosion and destruction during operation.
