Problems solved by technology
The advantages of this process are short process, small equipment size, less land occupation, good stability of steel slag, granular slag, good separation of slag and iron, f-CaO content in slag is less than 4% (mass fraction, the same below), and is convenient for tailing. The application of slag in the building materials industry; its disadvantages are high requirements on the fluidity of slag, it must be liquid thin slag, the slag treatment rate is low, there is still a large amount of dry slag discharged, and improper operation during processing is prone to explosion.

The invention provides a cylinder screen mechanism for steel slag treatment. The cylinder screen mechanism is characterized by comprising a cylinder screen mechanism body; the cylinder screen mechanism body is composed of a power device, a cylinder screen and a steel slag conveying device; the power device comprises a motor and a speed reducer; a steel slag discharge port is formed in the lower end of the cylinder screen; a guide plate is arranged at the bottom of the steel slag discharge port; the steel slag conveying device is arranged at the bottom of the guide plate; a feeding port is formed in the top of the higher end of the cylinder screen; the cylinder screen is divided into an inner screen cylinder and an outer screen cylinder; stirring shafts are uniformly arranged on a rotatingshaft at equal intervals; a collecting hopper is arranged below the cylinder screen; and a slag outlet is formed below the collecting hopper. The cylinder screen mechanism for the steel slag treatmentis suitable for treating steel slag by a rotating-drum method, can be used for treating liquid thin slag, semi-solid steel slag and cooled steel slag, the application range of treating the steel slagby the rotating-drum method is enlarged, the use efficiency is high, and the separation effect is good.
Description
technical field [0001] The invention belongs to the field of steel slag processing, and in particular relates to a cylinder screen mechanism for steel slag processing. Background technique [0002] A by-product of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, and salts formed by the reaction of these oxides with solvents. Steel slag contains a variety of useful components: 2% to 8% of metallic iron, 40% to 60% of calcium oxide, 3% to 10% of magnesium oxide, and 1% to 8% of manganese oxide, so it can be used as raw material for iron and steel metallurgy. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. Steel slag is clinker, which is a heavy melting phase and has a low melting temperature. When re-melted, the liquid phase is formed...
