Embodiment Construction
[0021] The present invention will be further described below with reference to specific embodiments.
[0022] The niobium alloyed high chromium cast iron grinding ball according to the present invention has a chemical composition of C: 2.5-3.0%, Si: 0.3-0.8%, Mn: 0.6-1.0%, P: <0.1%, S : <0.1%, Cr: 14.0-16.0%, Nb: 0.1-0.2%, RE: 0.1-0.2%; the balance is Fe.
[0023] Carbon: Carbon content is the most significant factor affecting the structure and performance of high chromium cast iron. As the carbon content increases, the wear resistance increases, but the toughness of the alloy decreases. According to the actual wear conditions of the grinding balls, we control the carbon content in the range of 2.5%-3.0% by mass.
[0024] Chromium: It can be seen from the Fe-Cr-C alloy phase diagram that in order to ensure that the carbides are 7 C 3 The chromium content must be greater than 12%. Chromium is the main alloy, in addition to forming carbides with carbon, it is partially dissolved in ...
