Description

Recycling method of stabilized ballast

The invention relates to an electric arc furnace ballast treatment method. Specifically, the present invention relates to a resource treatment method of electric arc furnace slag.

The iron and steel industry is a very important basic industry in China, and its related industries are very extensive. The iron and steel plants produce more than one million tons of slag each year. If they are not used rationally, simply storing the slag will cause storage space problems. It will also cause environmental pollution.

The smelting process of electric arc furnace steelmaking is divided into three stages according to its chemical reaction, namely the melting period, the oxidation period and the reduction period. The electric arc furnace steelmaking ballast is the molten ballast discharged from the steelmaking process. According to the time of the ballast production, it can be divided into oxidation ballast and reduction ballast. The oxidation ballast has a high content of iron, a hard texture and a high specific gravity. It is a dark brown block with stable physical and chemical properties. The unstabilized reduced ballast contains less iron but more calcium oxide and magnesium oxide, which is gray-brown powder or lump. Since the reduced ballast contains free lime (f-CaO), it swells and disintegrates easily when exposed to water. Therefore, apart from being used as a raw material in the cement process, the reduced ballast has no effective way to remove it due to poor volume stability. The reduction ballast must be stabilized before it can be used safely. The stabilized reduced ballast is in powder form and has a high water content, which is difficult to use effectively. A large amount of storage will reduce the production capacity of the stabilized reducing ballast process and indirectly affect the production capacity and cost of the steel plant.

Domestic public works and construction industries have a huge demand for concrete pellets every year. Among them, trench pipe projects such as sewage sewers, water pipes, natural gas pipelines and other projects require a large amount of Controlled Low-Strength Material (CLSM for short) ). The pellets in CLSM can be recycled pellets and industrial by-products instead of natural pellets. Due to the huge amount of reduced ballast produced by each electric arc furnace steelmaking plant every year, Taiwan’s natural resources are very limited. The use of ballast to replace precious natural resources will ensure the sustainable existence of resources. The stabilized reducing ballast is rich in calcium hydroxide. Calcium hydroxide reacts with silicon-containing materials or aluminum-containing materials. However, it takes at least one to two months at room temperature to have a more obvious reaction result. If this is done It is not economical to produce artificial pellets or 預鑄 products in the industrial process. Therefore, there is a great need to develop a method that can accelerate the reaction of Bu Zuolan and convert a large amount of stabilized reducing ballast into a renewable resource with use value in a short time.

In order to solve the above-mentioned problems, the purpose of the present invention is to develop a method that can convert a large amount of stabilized reducing ballast into renewable resources in a short time.

Discussion of experimental results

As shown in Table 1 above, the stabilized reducing ballast recycling method of the present invention can obtain a cured product ^{with a compressive strength of 10 kgf/cm 2} to 100 kgf/cm ^{2 in a short time.} The cured product with the above-mentioned compressive strength is a material with economic value, which can be used in large quantities in CLSM materials and non-structural concrete materials to increase the use of channels, reduce the stacking requirements and reduce the cost of steelmaking.

Observing Examples 1 and 3, after curing and reacting at a curing temperature of 60°C for 3 hours, the compressive strengths of the resulting cured products were 10.2 kgf/cm ² and 11.7 kgf/cm ² , respectively, indicating that the method of the present invention can be used in 3 hours It can transform the stabilized reducing ballast into a usable solidified substance inside. Looking back at Examples 1 and 3, after curing and reacting at a curing temperature of 60°C for 6 hours, the compressive strengths of the cured products obtained are 20.1 kgf/cm ² and 23.1 kgf/cm ^{2 respectively} , compared with those obtained after 3 hours The compressive strength of the cured product after 6 hours is about twice the compressive strength of the cured product after 3 hours, indicating that the method of the present invention can increase the compressive strength of the cured product in a short time.

Further, comparing Examples 2 and 4 with Examples 1 and 3, it is known that after the curing temperature is increased to 90°C, after the same heating time (3 hours), the cured products obtained in Examples 2 and 4 Compared with the compressive strength of the cured product of Examples 1 and 3, the compressive strength of the composite is increased by about half, respectively, 15.5 kgf/cm ² and 16.3 kgf/cm ^2. It can be seen that increasing the temperature helps to increase the compressive strength of the cured product . Observe that after heating for 6 hours at a curing temperature of 90°C, the compressive strength of the resulting cured product is increased to 23.2 kgf/cm ² and 28.4 kgf/cm ^{2 respectively} , which means that approximately 25 kgf can be obtained after heating at 90°C for 6 hours. /cm ² , even close to 30 kgf/cm ² of the cured product with compressive strength.

Looking at the cured products heated for 24 hours in Examples 1 to 4, regardless of curing temperature of 60°C or 90°C, the cured products obtained have ^{a compressive strength of about 30 kgf/cm 2} and heated at 90°C The cured product for 24 hours has ^{a compressive strength close to 40 kgf/cm 2.} It can be seen that the method of the present invention can greatly shorten the time to convert stabilized reduced ballast into a cured product.

Based on the above experimental results, using the method of the present invention, a large amount of stabilized reduced ballast can be converted into a cured product with a use path in a short time. The cured product is a renewable resource, which can be used in large quantities for CLSM materials and non-structural materials. Concrete materials, thereby increasing the use of stabilized reducing ballast and reducing the processing cost of stabilized reducing ballast.
