Example Embodiment

[0066] Example 1

[0067] This embodiment provides a method of taking a mid-coal coalfine method, including the step of mixing each individual coke coal, each single-type coking coal and weight percent, with a gas coal 15%, 1 / 3 coking coal 30%, gas plant 10% of coal, 15% of high sulfurprine, 30% of poor coal, listed in Table 1 below, and the quality indicators of each single coking coal used in Example 1.

[0068] Table 1

[0069]

[0070] Pre-pulverizing gas coal, the volume percentage of particles (less than 3 mm) of the particles were 87.8%, and then each single-species coal was mixed with mixing, and then into the pulverizer together. The volume (less than 3 mm) particles have a volume percentage of 88.7%, a heap density of 1.03T / m. 3 . The indicator data prepared to obtain coal coal is shown in Table 2.

Example Embodiment

[0079] Example 2

[0080] This embodiment provides a method of taking a mid-solid coal union, including the step of mixing each individual coke coal, each single-type coking coal and weight percent, with a gas coal 5%, 1 / 3 coking coal 40%, gas plant 5% of coal, 10% of high sulfurprise, 30% of poor coal, and the quality indicators of each single coking coal used in Example 2 were in Table 1.

[0081] Pre-pulverizing gas coal, the volume percentage of particles (less than 3 mm) of the particles were 87.8%, and then each single-species coal was mixed with mixing, and then into the pulverizer together. The volume (less than 3 mm) particles have a volume percentage of 89.2%, a heap density of 1.03T / m. 3 . The indicator data prepared to obtain coal coal is shown in Table 4.

[0082] Table 4

[0083]

[0084] Among them, "-" means that the indicator is not required in the product standard.

[0085] As can be seen from Table 4, with the coal quality indicator data meets the requiremen...

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...
