Problems solved by technology
[0003] The following problems often exist in the process of processing steelmaking slag: 1. Since the steelmaking slag is often piled up and preheated, it is not conducive to subsequent processing, so it needs to be cooled before grinding, but the piled up Second, because part of the steelmaking slag is too round, it is difficult to be ground and unloaded by the grinding device during the grinding process, resulting in the accumulation of steelmaking slag at the grinding position, affecting work efficiency

Embodiment Construction
[0030] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0031] like Figure 1 to Figure 6 Shown is an environmentally friendly treatment method for iron and steel smelting slag, which uses slag treatment equipment. The process for processing the slag also includes the following steps:
[0032] S1. Collection operation: take out the steelmaking slag in the furnace and stack them together by manual or mechanical assistance;
[0033] S2. Cooling and humidity adjustment: add water to the steelmaking slag through the humidity adjustment and spreading device 2 to adjust the humidity and lower the temperature;
[0034] S3. Grinding and drying: the grinding and drying device 3 grinds the steelmaking slag and dries the moisture;
[0035] S4, unloading and palletizing: wrapping the processed coiled material aft...

The invention relates to an environment-friendly treatment method for steel smelting slag. Slag treatment equipment is used and comprises a treatment cylinder, a humidifying and spreading device and agrinding and drying device, the humidifying and spreading device is arranged on the inner wall of the upper end of the treatment cylinder, and the grinding and drying device is arranged on the innerwall of the lower end of the treatment cylinder. According to the method, the stacked slag is spread, and internal waste heat is led out by adding water, so that the problem that heat of the stacked steel-making slag is difficult to dissipate is solved; through the dry hot air, the steel-making slag can be assisted to be discharged from the grinding position, and the cooling water in the previousprocedure is removed, so that the water is prevented from serving as a lubricant in the grinding process; and the operation of the equipment is realized in a one-machine multi-function mode, and the cost is greatly reduced.
Description
technical field [0001] The invention relates to the technical field of iron and steel smelting production, in particular to an environmentally friendly treatment method for iron and steel smelting slag. Background technique [0002] Steelmaking slag refers to the general term for the products formed by the physical and chemical reaction of the oxides formed by the impurities in the metal material in the steelmaking process by the oxidation of the oxidant and then with the slagging agent and the furnace lining. Slag has a lower density than molten steel and usually covers the surface of molten steel. The main task of steelmaking is to remove harmful impurities in molten steel to the greatest extent. The application value of steel slag is very great, mainly including: recycling of scrap steel, application in steel production, steel slag cement production, road engineering and building filling, and steel slag phosphate fertilizer. [0003] The following problems often exist i...
