The Key Role of Pulverized Coke Binder in the Recycling of Coke Powder Part one

Coke is an extremely important industrial resource, widely used in metallurgy, chemical industry and other fields, but coke will produce a small amount of powder during coke breaking, transportation and use. In the process of producing finished products in coking plants, the transmission process of steel plant conveyor belts A certain amount of powder will be produced in the process, and the recovery of these powders requires the use of pulverized coke binders. It is reported that the coke powder produced in these processes accounts for about 20% of coke every year. Most of these coke powders are used to make coal for power generation, and the other part is piled up randomly, which not only wastes resources, but also pollutes the environment. With the increasing demand for coke and the increase of coke resources (coking coal), the carbon-to-steel ratio generally used in steelmaking in steel plant is 1:2, and the consumption of coke is large. How to fully and effectively apply coke powder, thereby To achieve greater value, this issue has aroused widespread concern in the metallurgical industry.

There are many types of traditional pulverized coke binders, but there are mainly two types of asphalt and humic acid. Asphalt is used as a pulverized coke binder to produce coke blocks, which has a good effect (carbonization is required), but requires a lot of investment and complicated processes; while humic acid is used as a binder, the cost is low, pollution-free, and the process is complicated, but the coke cannot be used in various used in kilns and furnace. The coke produced by our pulverized coke binder technology has a thermal strength close to that of coke and can be used in smelting, foundry, chemical and other industries. Moreover, the production process is simple, the cost is low, and no heating or carbonization is required during the production process, which truly realizes environmental protection and energy saving. The coke block made of our pulverized coke binder has many functions, high strength and good thermal stability, and it can be used in various kilns and furnace without bursting or scarring, good extinguishing performance, and the performance is similar to that of coke. Generally, coke powder can be recycled through cold press process, in which specific pulverized coke binder is required. In the metallurgical industry, coke can be partially replaced, which can not only save costs, but also free up space for factories.
