Embodiment 1

[0096] This embodiment provides a method for calculating the smelting cost of iron ore powder. Taking Brazilian BRBF powder as an example, calculate the cost required to smelt each ton of molten iron with this iron ore powder, and then compare it with the cost of other iron ore powders. Specifically include:

[0097] 1. The cost of iron ore powder, fuel and flux required to smelt each ton of molten iron with the iron ore powder

[0098] In terms of mass percentage, the iron ore powder is used alone for sintering, and its ratio is 78.5%. Flux and fuel are internally blended. The single caustic alkalinity of sinter is calculated as 2.0, and the ratio of fixed quicklime is 4%. The proportion of limestone and limestone makes the magnesium-aluminum ratio of sintered ore be 1, and the suitable coke powder proportion of sintered ore is 5%. The ratio of Brazilian BRBF powder single sintering sintering material is as follows:

[0099] Table 2 Ratio of Brazilian BRBF powder single-sin...

Embodiment 2

[0134] This example provides a method for calculating the cost of smelting iron ore powder. Taking Brazil csn ioc6 powder as an example, calculate the cost required to smelt each ton of molten iron with this iron ore powder, and then compare it with the cost of other iron ore powders . Specifically include:

[0135] 1. The cost of iron ore powder, fuel and flux required to smelt each ton of molten iron with the iron ore powder

[0136] Brazil csn ioc6 powder single sintering material ratio table is as follows:

[0137] Table 3 Ratio of single-sintered sintering materials of Brazil csn ioc6 powder

[0138]

[0139] The ratio, burning loss and moisture in Table 3 are based on the actual ratio and the performance parameters of raw materials. The composition of sinter is calculated from the chemical composition, moisture and burning loss of a single ore, fuel, and flux. Calculated according to Table 3:

[0140] X1 = total weight of iron contained in 100 kg of sintered mixtu...

Abstract

The invention relates to an iron ore powder smelting cost measuring and calculating method, and belongs to the technical field of iron ore powder cost measuring and calculating. The iron ore powder smelting cost measuring and calculating method comprises the step of determining the total cost required for smelting each ton of molten iron by using iron ore powder according to the iron ore powder cost, the fuel cost, the flux cost, the desulfurization cost, the dezincification cost and the fuel cost required for smelting each ton of molten iron in a blast furnace according to the slag productionamount required for smelting each ton of molten iron. According to the iron ore powder smelting cost measuring and calculating method, various influence factors in the sintering and blast furnace smelting processes are considered, and the comprehensive cost of iron ore powder in sintering and blast furnace smelting can be accurately evaluated.

Description

technical field [0001] The present application relates to the technical field of iron ore powder cost calculation, and in particular to a method for calculating iron ore powder smelting cost. Background technique [0002] With the increasing cost pressure in the steel industry, low-cost and high-quality products are the magic weapon for enterprises to improve their market competitiveness. How to choose iron ore economically and rationally, so that it can not only meet the steelmaking production requirements under the existing production conditions, but also minimize the ironmaking cost is the key for enterprises to improve their competitiveness and increase their economic benefits. [0003] At present, the cost-effectiveness of iron ore is mainly evaluated by ton price (characterizing the cost-effectiveness of iron ore, which means the price of one grade of iron ore) in the world. The advantage is that the calculation is simple and can directly reflect the value of iron in i...
