Device and method for producing zirconium silicate shot through continuous-method ceramic melt atomization

Abstract

The invention discloses a device and a method for producing zirconium silicate shot through continuous-method ceramic melt atomization, and relates to the technical field of production of zirconium silicate shot. A feeding port of a feeding pipe is provided with an electromagnetic valve and a quantitative feeding device communicating with the electromagnetic valve, a vertically-downward tungsten needle is fixed on the side, located inside a furnace body, of a furnace cover, closing or opening of the electromagnetic valve enables the tungsten needle and a tungsten rod plug to form or not to form closed-loop circuit linkage correspondingly, when the tungsten needle is immersed in the upper portion of the melt inside the furnace body, the tungsten needle and the tungsten rod plug form a closed-loop circuit, wherein the electromagnetic valve is closed; when the melt inside the furnace body falls to be not in contact with the tungsten needle, the circuit is disconnected, the electromagneticvalve is opened, a ceramic raw material is added into a tungsten crucible through the quantitative feeding device until the closed-loop circuit is electrified, the electromagnetic valve is closed, inthis way, the cycle is carried out, and automatic feeding is realized. According to the device and the method, the quality of micro-beads obtained through atomization is consistent, and the rate of finished products is high.

Description

technical field [0001] The invention relates to the technical field of producing zirconium silicate shot peening microbeads, in particular to a device and method for continuously producing zirconium silicate shot peening by atomizing ceramic melt. Background technique [0002] Zirconium silicate shot peening microbeads are mainly melted in an electric arc furnace, and then poured into the middle insulation bag, and the melt gradually flows out from the bag, and is atomized into microbeads by compressed gas. Although the melting temperature of the electric arc furnace is high and the speed is fast, the production is discontinuous, the energy consumption is wasteful, the process parameters of the melt are difficult to control, the size range of the obtained microbeads is difficult to control, and the yield is low. Contents of the invention [0003] The technical problem to be solved by the present invention is that the existing method for producing zirconium silicate shot-pe...
