CN113802049A CADI (computer aided design) grinding ball casting
The invention discloses a CADI (cast aluminum di) grinding ball casting process, which specifically comprises the following steps: s1, smelting raw materials: adding the raw materials into a medium-frequency induction electric furnace for smelting, wherein the temperature of molten iron in the smelting process is 1600-1640 ℃, detecting the The equations presented depend on rolling or burnishing feed, on the normal displacement of the ball, and on the initial surface roughness from previous turning and/or grinding. Finally, some authors developed FEM models, capable of predicting surface integrity [ 29,30 ]; in this work, a novel FEM model is also presented in order to Isotropic finishing of austempered iron casting cylindrical parts

Grinding media balls manufacturing process Xinma
Quenching process: First, the grinding ball is heated to a certain degree within a specific time, and then it is directly quenched in oil or air for several minutes. Tempering process: the quenched grinding ball is heated to a certain extent for a period of time.The tools and equipment used in the casting process are inexpensive. It is possible to make the casting of any shape and size. The casting of any size can be performed up to 200 tons; It is the cheapest way to produce shapes and sizes with different mechanical properties. Disadvantages of Casting Process: The following disadvantages Casting Process: Definition, Working Process, Types in detail

Grinding in Ball Mills: Modeling and Process Control Sciendo
Keywords: Ball mills, grinding circuit, process control. I. Introduction Grinding in ball mills is an important technological process applied to reduce the size of particles which may have different nature and a wide diversity of physical, mechanical and chemical characteristics. Typical examples are the various ores, minerals, limestone, etcThe heat treatment process is the use of two-stage heat quenching and low-temperature tempering. At the rate of less than 70 °C / h, the temperature is increased to 650-680 °C for 2 hours, at the temperature increasing to 950 °C for 4 hours, forced air-cooling, oil-cooling, and special quenching liquid cooling respectively, and tempering isHeat treatment process for high chromium grinding ball
