Problems solved by technology
[0003] However, the converter waste steel slag in the current market has the following problems in the process of comprehensive treatment: a. In the process of spraying water to the converter waste steel slag, the water-sprayed converter waste steel slag cannot be turned over at the same time, so that the mechanical Reduced applicability
b. Traditional machinery cannot spray water evenly on the waste steel slag of the converter, and the spraying area is small, which reduces the spraying efficiency of the machine

Embodiment Construction
[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0033] refer to Figure 1-7 As shown, a method for comprehensively treating waste steel slag in a converter, the method for comprehensively treating waste steel slag in a converter specifically includes the following steps:
[0034] S1. Move: first move the processing equipment to the side of the converter waste steel slag that needs comprehensive treatment, so that the solid spraying device 2 is located directly above the converter waste steel slag;
[0035] S2. Spraying: After the step S1 is completed, when the solid spraying device 2 is moved directly above the...

The invention relates to a comprehensive treatment method for converter waste steel slag. A fixing device, a spraying device and a moving device are provided, wherein the spraying device comprises a round hollow barrel, an electric push rod, a round block, a rubber pad, a round plate, a sealing plug, an arc plate, a positioning rod, a first round through hole and a water spraying frame. Through cooperation of the fixing device, the spraying device and the moving device, firstly, a machine moves to the position beside the converter waste steel slag needing to be subjected to comprehensive treatment, the spraying device is located over the converter waste steel slag, at the moment, the spraying device is started and evenly sprays water to the converter waste steel slag, the spraying area is increased, and accordingly the work efficiency during mechanical spraying is improved; and after spraying, the moving device is started at the moment, the moving device turns over and stirs the converter waste steel slag at the same time, and the applicability of the machine is improved.
Description
technical field [0001] The invention relates to the field of converter waste steel slag, in particular to a comprehensive treatment method for converter waste steel slag. 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 main composition is tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. Steel slag is clinker, which is a heavy melting phase with low melting temperature. When remelting, the liquid phase forms early. , good mobility. Steel...
