Method for producing nano alloy cast iron grinding balls by using nano material

Abstract

The invention discloses a method for producing nano alloy cast iron grinding balls by using a nano material, which comprises the following steps of: adding nano boron carbide into smelted alloy cast iron solution according to a mass ratio of (0.5-2):10,000; and fully mixing the nano boron carbide and the iron solution, and casting to obtain the high-hardness and compact-texture nano alloy cast iron grinding balls. Nano particles are taken as an additive and can become nuclei in the alloy iron solution, so the produced grinding balls have better wear resistance.

Description

technical field [0001] The invention relates to a production method of alloy cast iron grinding balls, in particular to a production method of making alloy cast iron grinding balls with nanometer materials. Background technique [0002] Alloy grinding balls are widely used in powder engineering in mining, building materials, electric power and other industries. They are consumable materials. The annual domestic demand is more than one million tons, and the demand is very huge. [0003] Due to the large consumption of grinding balls, how to reduce the unit consumption of grinding balls has become a common concern of the majority of scientific research workers and enterprises using grinding balls. At present, the grinding balls commonly used at home and abroad mainly include forged steel balls, low-alloy cast iron grinding balls, and high-alloy cast iron grinding balls. Forged steel balls have high abrasion and are only suitable for semi-autogenous grinding or mills with spec...
