Problems solved by technology

[0005] In the prior art, the halide solution is sprayed directly by spraying pipes before the sintered ore enters the blast furnace, and the sprayed sintered ore is directly sent to the blast furnace for ironmaking; Inhomogeneity affects the pulverization performance of the subsequent sinter at low temperature reduction
At the same time, in the prior art, the spraying liquid is generally purchased directly from the prepared calcium chloride solution and transported to the ironworks for use, which has the disadvantages of high cost and inconvenient use.

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] During specific implementation: if figure 1 As shown, a sinter conveying system includes a sinter conveying belt 1 and a halide solution spraying system capable of spraying the sinter on the sinter conveying belt 1, which is characterized in that it also includes a homogenizing silo 2. The inlet at the upper end of the homogenizing silo 2 is connected with the discharge end of the sinter conveyor belt 1, and the outlet of the homogenizing silo 2 is connected with the blast furnace.

[0033] In this way, a homogenizing silo is added in front of the blast furnace. After the sinter is sprayed with halide by the halide solution (calcium chloride solution is used in this embodiment) spray system, since the sinter itself still has a certain temperature, the Sending into the homogenization silo to stay for a period of time can make the sprayed halide solutio...

Abstract

The invention discloses a conveying system for sintered ore. The conveying system comprises a sintered ore conveying belt and a halide solution spraying system capable of spraying solutions on the sintered ore on the sintered ore conveying belt. The conveying system is characterized by further comprising a homogenization bin, an inlet in the upper end of the homogenization bin is connected to the discharge end of the sintered ore conveying belt, and an outlet of the homogenization bin is connected to a blast furnace. The conveying system is simple in structure, convenient to use and low in cost, can realize on-site preparation of the halide solutions, can greatly improve the adhesion uniformity of the halide solutions to the sintered ore, can effectively improve the low temperature efflorescence performance of the sintered ore and can be applicable to the blast furnace.

Description

technical field [0001] The invention relates to a pre-smelting technology for ironmaking blast furnace sintered ore, in particular to a sintered ore conveying system. Background technique [0002] Sintering is to mix various powdery iron-containing raw materials with an appropriate amount of fuel and flux, and add an appropriate amount of water. After mixing and pelletizing, a series of physical and chemical changes will occur on the material on the sintering equipment, and the ore powder particles will be bonded. Blocks for use in ironmaking blast furnaces. At present, due to the severe situation in the iron and steel industry, optimization of sinter ore blending is often adopted to reduce production costs, which has brought about a certain degree of decline in sinter indicators, especially the low-temperature reduction and pulverization performance of sinter ore, which seriously restricts the next process of ironmaking blast furnace. Furnace is running smoothly. [0003]...
