In-series merging arrangement process for two blast furnace ore coke groove systems

Abstract

The invention discloses an in-series merging arrangement process for two blast furnace ore coke groove systems. The blast furnace ore coke groove systems comprise a blast furnace ore coke groove I, a blast furnace ore coke groove II, a feeding system on the groove, feeding systems below the groove, an ore return system and a coke return system, wherein the blast furnace ore coke groove I and the blast furnace ore coke groove II are in in-series merging arrangement along the straight line direction; and the blast furnace ore coke groove I and the blast furnace ore coke groove II share one set of sharing feeding system on the groove, and the blast furnace ore coke groove I and the blast furnace ore coke groove II are both provided with a set of independent feeding system below the groove. In the in-series merging arrangement process, the ore coke grooves are in in-series merging arrangement, and only one set of the feeding system on the groove, the ore return system and the coke return system is needed; and in the in-series merging arrangement process, the general arrangement is more compact, the floor space is small, each system is more simple, system equipment is less and the investment of civil engineering and equipment is low. Simultaneously, the system failure rate is low, the system operation and maintenance are simple and the production cost is low, pollution sources such as dust, noise and the like are easy to control intensively, and the in-series merging arrangement process has the advantages of energy conservation, environmental protection and the like.

Description

technical field [0001] The invention belongs to the technical field of ironmaking production and bulk material processing in the iron and steel metallurgical industry, and in particular relates to a process for combining and arranging coke tank systems of two blast furnaces in series. Background technique [0002] During blast furnace production, various raw materials such as coke and sintered ore are transported to the ore coke trough by belt conveyors on the trough for storage. As far as the ore and coke tank integrated ore tank system is concerned, in the prior art, the setting of the coke tank corresponds to the blast furnace, that is, each blast furnace corresponds to a completely independent ore coke tank system, even if two When the blast furnace is planned and designed at the same time, each blast furnace also corresponds to a set of completely independent ore coke tank system, that is, the feeding system above the tank, the feeding system under the tank, the ore ret...

Problems solved by technology

As far as the ore and coke tank integrated ore tank system is concerned, in the prior art, the setting of the coke tank corresponds to the blast furnace, that is, each blast furnace corresponds to a completely independent ore coke tank system, even if two When the blast furnace is planned and designed at the same time, each blast furnace also corresponds to a set of completely independent ore coke trough system, namely the over-trough feeding system, under-trough feeding system, ore returning and coke returning system, related transfer stations, fine ore bins, fine powder Two sets of coke warehouses need to be set up, so the occupied area is large, the overall layout is complicated and messy, the integrated pipe network and buildings are many and scattered, the project investment is high, the failure rate in the production process is high, and the installation and maintenance personnel of each system increase. , high production cost and other disadvantages
