Problems solved by technology

In general, the problem of mixing different components is a separate scientific and engineering challenge
[0004] Convective mixing does not ensure breakup of agglomerates (i.e., ingredient particles added to the melt)

Embodiment Construction

[0013] The present invention is based on the idea of ​​utilizing the processes that occur in the phase transition of materials in the two-phase region of the planar crystallization (solidification) front, and on the idea of ​​cyclically repeating these processes in the pulsating structure of the standing wave ultrasonic wave to disperse the particle population. In short, the process under consideration generates a specific combination of separating forces that arise and act on aggregates of constituent particles randomly dispersed in a liquid material (ie, a metal melt). These separation forces reach a maximum when aggregates of particles occur in the region closest to the crystallization (solidification) front and when the aggregates are absorbed by the two-phase region of the front. Then, when in the solid phase, the separation process is terminated or substantially slowed down. Under the conditions of the cyclic phase transition process, the separation process becomes more ...

Abstract

The invention relates to metallurgy. A melt is heated to a superheating temperature above the liquidus line and is poured into a lined and heated mould. As the bulk of the melt cools, the induced crystallization of the melt is carried out in a force field generated by ultrasonic emitters. The onset of crystallization is induced in the central region of the melt with the crystallization front spreading towards the periphery of the melt. After solidification, the billets are heated until they are completely melted, heating is discontinued and the natural crystallization of the melt is carried out so that the crystallization front spreads from the wall of the crystallizer to the centre of the melt. The processes of induced and natural crystallization and melting are periodically repeated as many times as is required for the ingredients in the billet to reach the desired degree of homogeneity. The point of completion of a phase transition is recorded by an ultrasonic measuring system. The heater and the ultrasonic emitters are switched on and off by a control unit comprising a temperature sensor and a sensor of the phase state of the melt. The result is an increase in the degree of homogenization.

Description

technical field [0001] The invention relates to the field of metallurgy, and in particular to a method and a device for improving the distribution uniformity of various additives in solutions and mixtures during metallurgical conversion. Background technique [0002] The concern with the problem of achieving a satisfactory homogeneity of the solution and especially of the mechanical mixture has not changed. The complexity of the problem is of great importance to science and Technology has always been extremely important. In any event, the formation of liquid and solid solutions is characterized by one set of properties to achieve the desired homogeneity, while the formation of mechanical mixtures or the distribution of mechanical components in liquid or solid solutions is characterized by another set of properties. Various methods are known to solve the problem of obtaining solutions and mixtures of the desired homogeneity. The most common ways are mechanical mixing, incr...
