Description
Technical field
The utility model relates to the structure of hot metal mixer, particularly relates to a kind of resistant to corrosion hot metal mixer.
Background technology
Hot metal mixer is the steel-making utility appliance between blast furnace and converter, it is mainly used in regulating and the equipment of molten iron supply and demand between balanced blast furnace and converter, ensure the molten iron supplying converter needs incessantly, molten iron stores and mixes molten iron composition and uniform temperature in hot metal mixer, and it is highly beneficial to converter steelmaking.In iron and steel enterprise domestic at present, hot metal mixer is as important production unit, and the continuity of producing for guarantee and the stability of molten iron serve vital effect.But the work-ing life of common hot metal mixer furnace lining only has about 1 year, this is mainly severely eroded due to the furnace lining of hot metal mixer in slag line position, and then has had a strong impact on the work-ing life of hot metal mixer furnace lining.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of furnace lining antiscour and corrosion resistance is strong, the resistant to corrosion hot metal mixer of long service life.
The utility model resistant to corrosion hot metal mixer, teapot shape body of heater comprises the furnace lining on furnace shell and furnace shell inwall, described furnace lining comprises vault, furnace bottom, the middle part of described furnace lining has built front wall, Hou Qiang by laying bricks or stones, described body of heater top is provided with molten iron inlet, upper right side is provided with spout of a teapot shape iron notch, and described furnace lining also comprises the adiabatic brick layer of the corundum-mullite that iron notch inwall is built by laying bricks or stones.
The utility model resistant to corrosion hot metal mixer, wherein said rear wall has built 16 layers by laying bricks or stones from bottom to top altogether along the short transverse of described body of heater, and the lowest layer is connected with furnace bottom, and the superiors are connected with vault, 8th layer is all stretched out 50mm to body of heater inner chamber to the 16th layer, and described front wall is identical with arranging of rear wall.
The utility model resistant to corrosion hot metal mixer, the superiors of wherein said front wall, rear wall all and between vault build shape angle at 45 ° respectively.
Hot metal mixer of the present utility model, iron notch inwall selects the adiabatic brick layer of high-quality refractory material corundum-mullite that is high temperature resistant and resistance to erosion, greatly strengthen the corrosion resistance of iron notch.Further, the slag line position serious in lining erosion adds lining thickness, improves furnace lining antiscour and erosional competency, extends hot metal mixer work-ing life.
Below in conjunction with accompanying drawing, resistant to corrosion hot metal mixer of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the main pseudosection of the utility model resistant to corrosion hot metal mixer.
Embodiment
As shown in Figure 1, the utility model resistant to corrosion hot metal mixer, teapot shape body of heater 1 comprises the furnace lining 3 on furnace shell 2 and furnace shell 2 inwall, and furnace lining 3 comprises the vault 4 at top and the furnace bottom 5 of bottom.Body of heater 1 top is provided with molten iron inlet 8, and upper right side is provided with opening spout of a teapot shape iron notch 9 outwardly, and the furnace lining 3 at this iron notch 9 place is the adiabatic brick layer 6 of corundum-mullite of building by laying bricks or stones on iron notch 9 inwall.Corundum-mullite insulation brick long service life, can the high temperature of resistance to more than 1700 DEG C, directly can contact flame, resistance to various atmosphere corrosion, low heat conduction, low heat capacity, and there is excellent thermal shock resistance energy, thus obviously can strengthen antiscour, the corrosion resistance of furnace lining 3, be conducive to extending furnace lining 3 work-ing life, and then extend dark iron furnace whole service life.
The middle part of furnace lining 3 has built front wall (not shown), rear wall 7 by laying bricks or stones, and for strengthening corrosion resistance, rear wall 7 has built 16 layers by laying bricks or stones from bottom to top altogether along the short transverse of body of heater 1, and the lowest layer is connected with furnace bottom 5, and the superiors are connected with vault 4.Simultaneously, in order to prevent the problem of vault 4 dross, the superiors of front wall, rear wall 7 all and between vault 4 build shape angle at 45 ° respectively, and namely vault 4 place adopts mould material to water and outpours an inclined-plane, this inclined-plane respectively with the superiors of front wall, the superiors' shape angle at 45 ° of rear wall 7.Like this, molten iron just can release along above-mentioned inclined-plane, efficiently avoid dross.Further, for increasing the corrosion resistance namely corroding the most serious slag line position in the middle part of furnace lining 3, do in the middle part of rear wall 7 and thickeied process, namely after, the 8th layer of wall 7 is all stretched out 50mm to body of heater 1 inner chamber to the 16th layer, namely stretch out 50mm to the right, like this, the thickness in the middle part of rear wall 7 just obviously increases compared with other part thickness, effectively improve anti-erosion herein, erosion resistibility, and then extend the work-ing life of furnace lining 3 entirety.Front wall is relative with the position of rear wall 7 and method to set up is identical, so place does not repeat.
Hot metal mixer in use, it is slag line position that furnace lining 3 corrodes the most serious position, the different situation of different sites erosion degree that hot metal mixer of the present utility model occurs in actual use according to furnace lining 3, redesign masonry construction, select more erosion resistant building materials, solve furnace lining 3 after a procedure the phase because of Eroded non-serviceable problem, extend furnace lining 3 work-ing life.Therefore, hot metal mixer of the present utility model improves the masonry construction at slag line position refractory brick, makes furnace lining 3 extend 4-5 month on the original basis work-ing life.
Above-described embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
