High-strength coke

Abstract

The invention relates to the technical field of chemical materials and concretely relates to high-strength coke. The high-strength coke comprises, by weight, 11-22% of 1 / 3 coking coal, 5-10% of ash, 40-60% of coking coal, 0.5-0.7% of sulfur, 10-15% of lean coal, 15-23% of fat coal and 20-25% of a volatile ingredient. The high-strength coke can be produced through a scientific process and has qualified quality.

Description

technical field [0001] The invention relates to the technical field of chemical materials, in particular to high-strength coke. Background technique [0002] Coke is one of the important raw materials for steelmaking. The quality of coke is not only related to the quality of steel, but also related to steelmaking equipment and processes. If the quality of the coke is better, a higher-level blast furnace can be used to produce higher-level steel. But today's coke is generally not strong enough, which is caused by the ratio of its various coking coals. Therefore, most of the current coke can only be produced and processed using lower-level processes, and only lower-level blast furnaces can be used. If high-grade blast furnaces cannot be used, the increasing demand cannot be met. Contents of the invention [0003] The purpose of the invention is to provide a high-strength coke with scientific production technology and high quality. [0004] The technical solution adopted i...
