Adjustable high-temperature liquid state steel slag granulating device

Abstract

The invention relates to an adjustable high-temperature liquid state steel slag granulating device which comprises a steel slag granulator, a gas transmission pipeline, a gas flow adaptor, a gas flowpressurizing pipeline, a gas storage tank, a compressed air pipeline and an adjusting valve, wherein the steel slag granulator comprises a lifting adjusting mechanism, a transverse adjusting mechanism, an angle adjusting mechanism and a supersonic speed gas ejector; the transverse adjusting mechanism is arranged on one side of the lifting adjusting mechanism, the angle adjusting mechanism is arranged on one side of the transverse adjusting mechanism, and the supersonic speed gas ejector is arranged on one side of the angle adjusting mechanism. By means of the lifting adjusting mechanism, the optimum working position is found to achieve a relatively ideal liquid state steel slag granulating effect. By means of the transverse adjusting mechanism, the distance to the flowing liquid state steel slag is adjusted, so that a flying cooling distance of the granulated steel slag in air can be achieved more efficiently. By means of the angle adjusting mechanism, the track of a flying parabola ofthe liquid state steel slag after supersonic speed gas flow ejection is changed, so that multi-dimensional adjustment can be carried out according to different slag states.

Description

technical field [0001] The invention belongs to the technical field of steel slag treatment, in particular to an adjustable high-temperature liquid steel slag granulation device. Background technique [0002] Steel slag will be produced in the production process of steelmaking. When processing steel slag, hot braising method, hot pouring method, drum method, water quenching method and granulation method are usually used. The granulation method is to melt the steel slag at high temperature. When the liquid slag is poured out, it will fly forward under the impact of compressed air. During the flight, the compressed air will oxidize the high-temperature liquid steel slag, making the slag form spherical fine particles; [0003] After retrieval of patent number CN110747302A, steel slag air quenching device and steel slag granulation method, the steel slag air quenching device includes a device main body with a forced cooling chamber. The lower side of the end of the chute of the...

AI Technical Summary

Problems solved by technology

[0004] There are following deficiencies in the process of use: Since the air outlet of the main air duct is a fixed air outlet, and the physical properties of different batches of slag also have certain differences, resulting in the ineffectiveness of air quenching and granulation. Adjust according to the state of slag, resulting in poor quality of some granulated finished products
