Problems solved by technology

[0002] Most of the existing ordinary coal blending coking coals use coking coal, fat coal, gas coal, 1 / 3 coking coal and other coking coals. The total coal resources in my country are 1.02 trillion tons, and the coking coal resource reserves are 280.3 billion tons, accounting for 280.3 billion tons of the country's ascertained coal resources. 27.6% of the reserves of coal resources, although the variety is relatively complete, but the structure and geographical distribution are very unbalanced

Embodiment 1

[0067] This embodiment provides a coking method for tamping coal blending, including the step of mixing individual coking coals, and the individual coking coals and their weight percentages are as follows: gas coal 15%, 1 / 3 coking coal 30%, gas fertilizer 10% coal, 15% high-sulfur lean coal, and 30% lean lean coal. The quality indicators of each single coking coal used in Example 1 are listed in the following Table 1.

[0068] Table 1

[0069]

[0070] The gas coal is pre-crushed, and the volume percentage of fineness (less than 3mm) particles after pre-crushing is 87.8%, and then each single coal is mixed according to the above weight percentage, and then put into the pulverizer together to make the coal into the furnace fine The volume percentage of high-density (less than 3mm) particles is 88.7%, and the bulk density is 1.03t / m 3 . The index data of the blended coal prepared are shown in Table 2.

Embodiment 2

[0080] This embodiment provides a coking method for tamping coal blending, including the step of mixing individual coking coals, and the individual coking coals and their weight percentages are as follows: gas coal 5%, 1 / 3 coking coal 40%, gas fertilizer Coal 5%, high-sulfur lean coal 10%, lean lean coal 30%, the quality index of each single coking coal used in embodiment 2 is the same as table 1.

[0081] The gas coal is pre-crushed, and the volume percentage of fineness (less than 3mm) particles after pre-crushing is 87.8%, and then each single coal is mixed according to the above weight percentage, and then put into the pulverizer together to make the coal into the furnace fine The volume percentage of high-density (less than 3mm) particles is 89.2%, and the bulk density is 1.03t / m 3 . The index data of the blended coal prepared are shown in Table 4.

Abstract

The invention belongs to the technical field of coking in the coking industry, and particularly relates to a tamping coal blending coking method, a product thereof and blended coal for coking. The tamping coal blending coking method comprises the step of blending various single coking coals to obtain blended coal, the coking coals do not contain coking coals, and the types and the weight percentages of the coking coals are as follows: 5%-15% of gas coal, 30%-40% of 1 / 3 coking coal, 5%-10% of gas-fat coal, 10%-15% of high-sulfur lean coal and 20%-30% of lean coal. The coking coal resource consumption can be reduced, and the requirement of long-term development can be met; meanwhile, coke quality is guaranteed, coal blending cost is reduced, and coke profit is increased.

Description

technical field [0001] The invention belongs to the technical field of coking in the coking industry, and in particular relates to a coking method for tamping coal blending, a product thereof and blended coal for coking. Background technique [0002] Most of the existing ordinary coal blending coking coals use coking coal, fat coal, gas coal, 1 / 3 coking coal and other coking coals. The total coal resources in my country are 1.02 trillion tons, and the coking coal resource reserves are 280.3 billion tons, accounting for 280.3 billion tons of the country's ascertained coal resources. Coal resource reserves account for 27.6%. Although the varieties are relatively complete, the structure and geographical distribution are very unbalanced. Among coking coal, coking coal and fat coal account for 24.3% and 13.6% of my country's coking coal resources, gas coal and 1 / 3 coking coal account for 46.9%, and lean coal accounts for 15.1%. It can be seen from the proportion that my country's...
