Abstract

The invention provides a device and a method for homogenizing high-temperature melt and belongs to the technical field of melt homogenization. The device provided by the invention consists of three parts, namely a melting tank, a stirring system and a heating system. The detailed steps for homogenizing high-temperature melt carried out by the device provided by the invention are as follows: adding hot silicate slag and quenching-tempering material into the melting tank; after heating to melt the raw material, turning off the power supply; enabling the stirring part of the cooled stirring system to fall into the high-temperature melt, and finishing fall-rise-fall operating actions for stirring the melt in order, wherein the stirring process and the heating process are carried out alternatively; and under the condition that the test result of the samples shows that the composition uniformity and viscosity of the melt are suitable for the process conditions that the fiber is formed or the glass ceramics is prepared, opening a choke plug of the melting tank and making the melt flow out via the flow hole by the gravity of the melt to finish the homogenization process. The homogenizing device and the homogenizing method, provided by the invention, have the advantages of good homogenizing effect, good high-temperature strength and long service life of the stirring part.

Description

technical field [0001] The invention belongs to the technical field of melt homogenization, and in particular relates to a high-temperature melt homogenization device and method, which are used for efficient stirring and mixing of silicate melt and solid conditioner. Background technique [0002] The homogenization of high-temperature melt has always been an important step in some industrial processes, such as metallurgy, glass production, mineral wool processing, etc. In order to obtain high-quality industrial products above, it must be in a high-temperature melting state to make the components evenly distributed . It is very difficult to realize the high-temperature stirring process. At present, the existing methods include pneumatic stirring, magnetic stirring, mechanical stirring, etc., all of which have certain limitations. For example, pneumatic stirring can only be effective for the melt when the viscosity is low, and the stirring process The overflow of gas will tak...
