Embodiment Construction

[0034] like Figures 1 to 3 As shown, a new hearth cooling structure is arranged on the outer periphery of the hearth carbon brick of the blast furnace, including the inner furnace shell 2 and the outer furnace shell 1, and the two are fixedly connected by a plurality of fixing parts 4; the inner furnace shell 2 and the outer furnace shell A plurality of water-cooled pipes 3 are laid between the shells 1, and the outside of the water-cooled pipes 3 is filled with heat-conducting refractory materials 5; the two ends of each water-cooled pipe 3 are respectively arranged outside the upper and lower ends of the hearth cooling structure, so that the whole Compared with the prior art, the layout can effectively reduce the cooling blind area, increase the cooling specific surface area, and reduce the opening of the furnace shell; when installing, firstly install the inner furnace shell 2 along the outer periphery of the blast furnace hearth, and then install the water-cooled tube 3 an...

Abstract

The invention discloses a novel hearth cooling structure and a mounting method thereof, and relates to the technical field of blast furnace cooling structures. The device is arranged on the periphery of a blast furnace hearth carbon brick and comprises an inner furnace shell and an outer furnace shell which are fixedly connected through a plurality of fixing pieces; a plurality of water-cooling pipes are laid between the inner furnace shell and the outer furnace shell, and the water-cooling pipes are filled with heat-conducting refractory materials; the two ends of each water cooling pipe are arranged on the outer sides of the upper end and the lower end of the hearth cooling structure correspondingly. The mounting method comprises the following steps: fixedly mounting the inner furnace shell along the periphery of the blast furnace hearth; the water cooling pipe and the fixing piece are welded to the side, away from the hearth, of the inner furnace shell; an outer furnace shell is installed on the side, away from the hearth, of the inner furnace shell, pipe distribution holes are formed in the outer furnace shell in advance or in the installation process, and the ends of the water cooling pipes penetrate through the outer furnace shell; a heat-conducting refractory material is filled between the inner furnace shell and the outer furnace shell and tamped; the cooling device is simple and reasonable in structure, low in cost, convenient and rapid to install and good in cooling effect.

Description

technical field [0001] The invention relates to the technical field of blast furnace cooling structures, in particular to a novel furnace hearth cooling structure and an installation method thereof. Background technique [0002] The cooling structure of the traditional blast furnace hearth is similar, from the inside to the outside of the furnace are: carbon bricks, carbon ramming layer, stave wall body, gap layer between wall body and water pipe, and water pipe. The announcement number is CN1067105C, and the name is In the description of the invention patent of the stave of the side wall of the blast furnace and its manufacture and use method, the structure of the general stave is disclosed: carbon refractory bricks are stacked on the inside of the blast furnace. Between the carbon refractory brick layer and the furnace shell, stamping refractory materials, cooling walls and pouring refractory materials are placed. The refractory bricks are stacked on the bottom of the hea...
