Abstract
The utility model belongs to the technical field of iron runners, and particularly relates to a composite iron runner which comprises a runner-shaped channel formed by building clay bricks; a runner-shaped inner wall is arranged in the runner-shaped channel; the top of the runner-shaped inner wall is flush with that of the runner-shaped channel; a casting layer is filled between the runner-shaped channel and the runner-shaped inner wall; the top of the casting layer is flush with that of the runner-shaped channel; the runner-shaped inner wall is formed by connecting a plurality of runner-shaped inner wall sections; the runner-shaped inner wall sections are abutted through a glossal groove in the bottom; a hole is formed in the top of the runner-shaped inner wall. The runner-shaped inner wall is arranged in the iron runner, the runner-shaped inner wall is formed in such a way that the runner-shaped inner wall sections are abutted through the glossal groove in the bottom, and the glossal groove abutting is convenient and quick; meanwhile, the hole is formed in the top of the runner-shaped inner wall, so that the hanging of the runner-shaped inner wall sections during the manufacturing process of the composite iron runner is facilitated.
Description
technical field
The invention belongs to iron runner technical field, be specifically related to a kind of compound iron runner.
background technology
Blast furnace is the major equipment of ironmaking, and blast furnace iron runner for many years uses frequently.Along with the level of intensification of smelting process in BF improves, iron runner is required to strengthen with refractory materials lining body.In general, a 1000m
3above blast furnace has more than two iron runner, 3000m
3above blast furnace has more than three or three iron runner, 4000m
3above blast furnace has 4 iron runners.The strengthening smelting of blast furnace, requires the lining body anti-slag iron aggressiveness of iron runner strong, easy to make, intensity is high, iron influx is large etc.An iron influx of current iron runner is at 100,000 tons-150,000 tons, do not catch up with intensification of smelting process in BF, the needs that tap a blast furnace fast far away.The amount of tapping a blast furnace that how to improve iron runner is a current main direction of studying.
summary of the invention
The purpose of this utility model is to provide a kind of compound iron runner.
The present invention is by the following technical solutions:
A kind of compound iron runner, comprise the ditch shape passage being built into by clay brick, be provided with ditch shape inwall in ditch shape passage, the top of ditch shape inwall flushes with ditch shape channel roof, between ditch shape passage and ditch shape inwall, be filled with pouring layer, the top of pouring layer flushes with ditch shape channel roof; Ditch shape inwall is formed by connecting by multistage ditch shape inner wall section, and between ditch shape inner wall section, by being located at the glossal canal docking of bottom, the top of ditch shape inwall is provided with hole.
The thickness of described ditch shape inwall is 50mm.
The thickness of described ditch shape passage is 150mm.
The utility model is provided with ditch shape inwall in the inside of iron runner, ditch shape inwall is docked through the glossal canal of being located at bottom by multistage ditch shape inner wall section, adopts the mode of glossal canal docking convenient and swift; At the top of ditch shape inwall, hole is set, the conveniently hanging of ditch shape inner wall section in the utility model making processes simultaneously.Ditch shape inwall can select existing Sialon goods as material, has extended the work-ing life of iron runner, can make the amount of tapping a blast furnace improve.
accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the docking scheme of ditch shape inner wall section;
Fig. 3 is the vertical view of ditch shape inwall in Fig. 1.
embodiment
Compound iron runner as shown in Figure 1, 2, 3, comprise the ditch shape passage 1 being built into by clay brick, in ditch shape passage 1, be provided with ditch shape inwall 3, the top of ditch shape inwall 3 flushes with ditch shape passage 1 top, between ditch shape passage 1 and ditch shape inwall 3, be filled with cast 2, the top of pouring layer 2 flushes with ditch shape passage 1 top; Ditch shape inwall 3 is formed by connecting by multistage ditch shape inner wall section 31, between ditch shape inner wall section 31, dock by the glossal canal 32 that is located at bottom, the top of ditch shape inwall 3 is provided with hole 33, hole 33 facilitates the hanging of ditch shape inner wall section 31 in the utility model making processes, the thickness of ditch shape inwall 3 is 50mm, and the thickness of ditch shape passage 1 is 150mm.The material of ditch shape inwall 3 can select existing Sialon goods as material, has extended the work-ing life of iron runner, can make the amount of tapping a blast furnace improve.
