Microwave heat treatment method for blast furnace granulated slag
The invention belongs to the technical field of slag resource reutilization, and provides a microwave heat treatment method of blast furnace water granulated slag, which comprises the following steps: carrying out microwave heat treatment on the blast furnace water granulated slag, and then cooling, the frequency of the microwave heat treatment is 900 to 930 MHz. According to the method, microwave is used for rapid heating, moisture in the blast furnace water granulated slag is removed, in the rapid moisture removal process, stress is generated in blast furnace water granulated slag particles, and cracks are formed in the water granulated slag particles or the water granulated slag particles are decomposed into small particles; after the microwaves reach certain power, the microwaves are turned off, an air blower is turned on, thermal stress is generated in the blast furnace water slag particles through rapid temperature change, and the particles are further promoted to generate cracks or fragmentation; and carrying out short-time ball milling on the blast furnace granulated slag subjected to microwave heat treatment to obtain the required fine powder.
本发明属于矿渣资源再利用技术领域，本发明提供了一种高炉水渣的微波热处理方法，包含如下步骤：将高炉水渣进行微波热处理后冷却即可；所述微波热处理的频率为900～930MHz。本发明的方法利用微波快速加热，排除高炉水渣中的水分，在水分快速排除过程中，在高炉水渣颗粒内部产生应力，促使水渣颗粒中形成裂纹或分解成小颗粒；在微波达到一定功率后，关闭微波，并开启鼓风机，通过温度急剧变化，在高炉水渣颗粒内部产生热应力，进一步促使颗粒产生裂纹或碎裂；再将微波热处理后的高炉水渣进行短时间球磨，就可获得所需细粉。
