Problems solved by technology

However, when two blast furnaces are planned and arranged at the same time, each blast furnace is designed with a set of coke ore trough system, which will occupy a large area. Two sets of transfer station and coke crushing bin need to be arranged, the total investment is high, and the failure rate also increases, which doubles the installation, maintenance, overhaul and personnel, and the cost is naturally high

Abstract

The invention belongs to the technical field of metallurgical iron making, and discloses a combination technical arrangement of two coke and ore tank systems. The invention mainly comprises sintering ore tanks, a flux tank fine ore bin and a coke breaking bin facility, and is characterized in that: the coke tanks and mixed ore tanks of two blast furnaces are arranged in the way of one-to-one combination; the sintering ore tank of each blast furnace is independently arranged; and the mixed ore tanks and the sintering ore tanks are arranged in parallel in a one to one manner. The mixed ore tankis arranged between the sintering ore tanks. A feeding tape machine is arranged on the coke ore tank, and the lower part of the coke ore tank is provided with a feeding and screening plant, a weighing funnel, a feeding tape machine, an ore and coke returning tape machine and a dust-removal system, and is also provided with a transfer station required for transferring and storing crude fuel, a fine ore bin and a fine coke bin facility. The invention has compact technical arrangement, smaller occupation of area, small number of matched equipments, and lower engineering investment, saves time ofequipment maintenance and repairing, can easily and integrally control the pollution source such as dust, noise and the like, and is an ideal arrangement method of the coke and ore tank which is shared by two blast furnaces.

Description

technical field [0001] The invention belongs to the technical field of metallurgy and ironmaking. Disclosed is a combination process layout of two coke ore tank systems. The coke ore tank system stores appropriate raw materials and plays the role of batching and adjustment in ensuring the stable production of the blast furnace, and is the main process facility of the blast furnace system. Background technique [0002] During blast furnace production, various raw materials such as coke and sintered ore are transported to the coke ore tank for storage by belt conveyors on the tank. In the conventional design, the layout of the coke ore tank corresponds to the blast furnace, that is, each blast furnace corresponds to a set of coke ore tank system. However, when two blast furnaces are planned and arranged at the same time, each blast furnace is designed with a set of coke ore trough system, which will occupy a large area. Both the transfer station and the coke crushing bin nee...
