Abstract
The utility model discloses a ceramic tuyere of a blast furnace, the primary structure of the utility model is a two-stage hollow truncated cone. The utility model has the advantages of simple structure, convenient manufacture, convenient operation, low cost, no water cooling, long service life, convenient disassembly, etc., and the utility model is an ideal accessory for a tuyere of a blast furnace.
Description
The utility model relates to a kind of blast furnace pottery air port, belongs to metallurgy industry blast furnace annex.
At present, the blast-furnace tuyere major part of blast-furnace smelting industry still adopts the hollow recirculated water cooling structure of red copper both at home and abroad, in use be subjected to the fretting wear of high temperature and slag and molten iron, the impact shock of air-flow, very easily damage, though there is cycle of higher pressure water to cool off in the air port, but scaling loss, drainage happen occasionally, make the replacing of air port cover frequent, influence the normal operation of blast furnace, and the processing and manufacturing difficulty in this air port is big, the cost height, dismounting inconvenience.
The purpose of this utility model provide with regard to being to overcome the deficiencies in the prior art part a kind of simple in structure, make blast furnace pottery air port easy to process, with low cost, as not need water-cooled, long service life.
The purpose of this utility model is achieved in that its structure is a hollow round table.
Compared to existing technology, the utlity model has simple in structure, make easy to process, with low cost, do not need advantages such as water-cooled, long service life, convenient disassembly.
Accompanying drawing and drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model user mode figure
Below in conjunction with drawings and Examples in detail the utility model is described in detail, its structure is a hollow round table.Because the utility model is an one with former two groups of water cooled tuyere unitized design, and adopt special ceramic material to form, high temperature resistant, do not need water-cooled, cost of manufacture can reduce by 50%, can improve 5 times work-ing life, and working mechanism of the present utility model is that the utility model 4 is installed on the blast furnace furnace wall 2, outer and former tuyere big sleeve 3 joins, straight blowpipe 5 is fixed on the neck of the utility model 4, and outer and blast tube, straight blowpipe 5 are sent in the blast furnace, guarantee the works better of blast furnace.
