Production method of cast steel shot by acentric atomizing

Abstract

The invention discloses a production method of a cast steel shot by acentric atomizing, which is characterized by comprising an acentric atomizing method. The method comprises the following steps: placing and fixing an acentric atomizing wheel on a centrifugal pan of a horizontal centrifugal casting machine; starting the centrifugal machine and then pouring; and pouring molten steel to a central pouring hole of the acentric atomizing wheel, wherein the molten steel falls into water linearly with high speed rotation of the centrifugal machine to form the steel shot. According to the production method of the cast steel shot by acentric atomizing, the hang time of molten steel is long, the molten steel is slowly cooled, uniform in particles and good in roundness, and the moulding process is easy to control. Better product quality and economic benefit can be obtained by using the acentric atomizing method to produce the steel shot.

Description

technical field [0001] The invention relates to a production method of centrifugal atomization of cast steel shot. Background technique [0002] Cast steel shot is a kind of abrasive that is often used in many industries when crushing. Different industries have different requirements for the size and hardness of the abrasive, and these abrasives are damaged very quickly. They are often replaced, which not only wastes materials, but also wastes A lot of time, affecting work progress. The production of cast steel shot, after smelting into molten steel, turns it into small steel balls below 0.3mm-3.0mm, all need to atomize the molten steel, and then fall into the water pool to cool down into beads, generally after high-pressure water impact atomization , The molten steel is cooled too fast, the particles are large when forming beads, the roundness is not good, and the forming process is not easy to control. Contents of the invention [0003] The technical problem to be solv...
