Technological R & D History of Ball Coking Process since the Last Century

世纪50年代和60年代末,世界上的一些公司就已开始了压球机型焦工艺的研究。 In the 1950s and the end of the 1960s, some companies in the world have begun to study the coke technology of the ball press . Its benefits peaked during the unprecedented growth of steel production, and it is expected that there will be a continuous period of rapid growth. The goal of all research work is to meet the following requirements: First, the use of briquette briquettes to make coke have the same or better performance than conventional coal. The second is a coke production process that allows the use of coke from non-cohesive coal and can produce consistently uniform quality. The third is an environmentally acceptable process. The fourth is a process that can provide the price of coke produced basically the same as conventional coke and meet the above requirements.
Some processes incorporate proven technologies, such as hard coal molding with bitumen binders and coking in conventional indirect heated narrow tank furnaces. Other processes studied some really difficult parts, and the processes were developed to enable continuous operation of the entire complex process in the future. The new technology includes semi-coke process steps for low-temperature carbonization, incorporating mixing and agglomerating methods, and final carbonization or treatment procedures. When the ball compaction method is adopted for most processes, the ball and extrusion methods in double rolls are also tried. For technical and economic reasons, ball press molding is generally more popular. 世纪70年代初,大多数工艺已发展到大规模的试验厂或开始生产阶段。 By the early 1970s, most processes had developed into large-scale pilot plants or started production. At the same time, part of the molding technology of coke oven materials was adopted. This technology increases the specific gravity of the coal and thus improves the quality of the coke. At the same time, it allows the use of low-grade coal or non-stick coal with high volatile content and poor expansion characteristics. This method can be seen as an improvement in tamping coking.
