In the iron and steel industry, waste linings are extremely attractive. During this process, cyanide is destroyed by high temperatures. Carbon and fluorine are also used in the industry. The amount of fluorite is also decreasing. Certain economic value. Recycling in the cement industry The recycling of the waste chute lining in the cement industry mainly considers two approaches: one is that the carbon part is used as fuel, and the other is that the refractory part is used as a substitute for raw materials. The combustion air is preheated to a very high temperature by heat exchange with the hot clinker, and almost any kind of fuel can be burned in the cement kiln. Cement kilns are usually fueled with pulverized coal, so a preferred waste tank liner that is ground can replace a portion of the coal. Al2O3 and silicon in the waste liner can be used as part of the raw materials to enter the production process. Cement plants with severe restrictions on the chemical composition or mineralogical composition, such as factories producing low-alkaline cement, have a high sodium content in the waste tank lining and will affect the quality.
In order to extend the service life and ensure the specified out-of-focus time, the best production conditions for each coke oven are selected, including: the quality of coal and the stability of coal addition, the determination of the required coking time, and the management and control of the condition of the furnace. And take necessary measures to stabilize the production conditions. In this case, the main focus is to focus on the continuous control of the temperature inside the heating fire. The degree of damage and wear of the furnace masonry depends not only on the length of production time of the coke oven but also on many other factors, including the properties of refractory refractories and fires that are used, the method of coke oven construction and oven, and the production of coke ovens. Influence of conditions, etc. Therefore, it is necessary to solve several single tasks related to the masonry repair methods used.
