Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0024] Please also refer to Figure 1 to Figure 4 , the blast furnace ironmaking equipment provided by the present invention is now described. Blast furnace ironmaking equipment, including an inner furnace body 100, an outer furnace body 200 sheathed on the outer periphery of the inner layer furnace body 100 and used to form a furnace chamber for ironmaking with the inner layer furnace body 100, and an outer layer furnace body 200 for connecting the inner layer furnace body 100 The bottom plate 400 at the lower end of the layer furnace body 100 and the outer layer...

Abstract

The invention provides blast furnace ironmaking equipment and relates to the technical field of metallurgical ironmaking equipment. The blast furnace ironmaking equipment comprises an inner furnace body, an outer furnace body used for enclosing the inner furnace body into a furnace cavity for ironmaking, a bottom plate and a plurality of air supply components, wherein the air supply components arecorrespondingly arranged at the lower part of the inner furnace body and the lower part of the outer furnace body. According to the blast furnace ironmaking equipment, the furnace cavity for ironmaking is defined by the inner furnace body, the outer furnace body and the lower bottom plate so as to achieve the effect that the air supply components are correspondingly arranged at the inner and outer sides of the annular furnace cavity to improve the air supply efficiency, and the problem of ineffective air supply caused by the too large inner diameter of a traditional blast furnace is avoided;meanwhile the air supply components arranged at peripheries of the inner side of the inner furnace body and the lower part of the outer furnace body can effectively supply air to the furnace cavity inthe middle part from both sides of the annular furnace cavity, so that the ironmaking efficiency is improved, the problem of ineffective air supply to the center due to the too large air supply diameter in a furnace is avoided, the air supply requirement is lowered, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of metallurgical ironmaking equipment, and more specifically relates to a blast furnace ironmaking equipment. Background technique [0002] The method of continuously producing liquid pig iron in a vertical reactor, that is, a blast furnace, using iron-containing ores such as coke, natural rich lump ore, sinter and pellets, and fluxes such as limestone and dolomite is called blast furnace ironmaking. It is a modern iron and steel production. important link. At present, the main process of blast furnace ironmaking is as follows: high-basic sintered ore, acid pellets and a small amount of natural lump ore are used as the furnace charge structure. The fuel is mainly coke and coal powder, and the iron-containing raw material is completed by blowing hot air at 1000-1250 degrees Celsius. reduction, and finally complete the production of pig iron through the separation of slag and iron. [0003] With the continuo...
