Problems solved by technology

At present, the material of the liner is high-chromium cast iron, and the wear-resistant surface of the liner directly bears the impact of the furnace charge, which causes greater wear to the liner and reduces the service life of the liner, thereby reducing the service life of the tank; the welding repair performance of high-chromium cast iron is relatively low. Poor, maintenance is difficult, and the liner is prone to fall off after the fixing bolts of the liner are worn

Embodiment Construction

[0016] The present invention will be further described below in conjunction with accompanying drawing.

[0017] Such as figure 1 , figure 2 , image 3 As shown, the bellless blast furnace weighing tank of the present invention includes a material wall 1 on which a liner 2 is arranged, and a grid-shaped partition structure 3 is arranged on the liner 2 .

[0018] By setting a grid-like spacer structure 3 on the liner 2 on the material wall 1, when loading materials, the raw materials that fall first fall into the grid and accumulate, so that the materials that fall later collide with the accumulated materials in the grid. , forming material abrasives, preventing the raw materials from directly impacting the liner 1, and the raw materials directly wear the spacer structure 3 more directly, and less wear on the liner itself, thereby significantly improving the service life of the liner and further improving the service life of the tank. Moreover, the present invention has simp...

Abstract

The invention discloses the technical field of blast furnace production, and particularly relates to a bell-less blast furnace weighing charging bucket. The bell-less blast furnace weighing charging bucket comprises a material wall, wherein a lining plate is arranged on the material wall; a gridding-type material isolation structure is arranged on the lining plate. The invention provides the bell-less blast furnace weighing charging bucket which is simple in structure and relatively long in service life.

Description

technical field [0001] The invention relates to the technical field of blast furnace production, in particular to a bellless blast furnace weighing tank. Background technique [0002] The bell-less blast furnace weighing tank is set under the charging gate, which is used to store, transfer and weigh the furnace material, and realize the loading under pressure. The inner surface of the lower and middle parts of the weighing tank is equipped with lining plates. When feeding, the tank liner is impacted by the falling material and plays a protective role. The liner is fixed on the shell with special bolts, and a sealing flange is welded at the bolt head on the outer surface of the shell to play a role of sealing and protection. At present, the material of the liner is high-chromium cast iron, and the wear-resistant surface of the liner directly bears the impact of the furnace charge, which causes greater wear to the liner and reduces the service life of the liner, thereby reduci...
