Abstract
The utility model discloses a blast furnace mixer with a novel iron outlet, including an outer layer and an inner lining connected each other, the outer layer is a steel shell, the inner lining is a furnace body formed by constructing fire-resistant material, the furnace body is provided with an arced furnace roof, a furnace bottom, a front wall and a rear wall in its structure, the upper side of the front wall is provided with the iron outlet in a projecting mode, the furnace roof is provided with an iron inlet, the iron outlet includes a top surface and a bottom surface, the front wall is extended outwards to form a sleeve wall along two sides of the bottom face, the top surface is flat top surface formed integratedly, and the top of the sleeve wall is connected with the top surface in a support mode.
Description
Technical field
The utility model relates to a kind of steel smelting equipment, particularly a kind of hot metal mixer.
Background technology
Hot metal mixer is a kind of smelting iron high temperature service of storing molten iron and even hot metal composition, keeping molten iron temperature.As depicted in figs. 1 and 2, existing hot metal mixer comprises skin and the liner that links together, skin is a box hat 1, liner is for to build the body of heater that forms by laying bricks or stones by refractory materials, body of heater structurally includes arc furnace roof 2, furnace bottom 3, antetheca 5 and rear wall 6, body of heater antetheca 5 tops outwards are provided with iron notch, furnace roof is provided with into iron mouth 7, iron notch comprises arc top surface 8 and is built by laying bricks or stones the ramp-like base 9 that forms by refractory lining brick, antetheca 5 stretches out along the both sides, bottom surface to build by laying bricks or stones and forms sleeve wall 5A, combining site at both sides sleeve wall 5A and end face 8 is provided with arch angle brick 11, and 11 pairs of arc top surfaces 8 of arch angle brick are played a supporting role.The erosion that the inner lining material at iron notch position is subjected to 1300 ℃ of high temperature liquid irons for a long time with wash away, be that hot metal mixer is impaired easily and influence the key position of bulk life time.Weathering and washing away the most frequent and the easiest position of being damaged is sleeve wall 5A body of wall lining brick below arc top surface 2 and both sides sleeve wall combining site arch angle brick 11.When iron notch goes out molten iron, the sleeve wall body of wall 5A at this position is subjected to washing away of high temperature liquid iron and scum and corrodes, continued under the impaired situation by Tie Kou both sides sleeve wall 5A, its maximum extent of damage can make the 450mm of width when newly building moulding by laying bricks or stones between the sleeve wall 5A body of wall of this iron notch both sides, position, through corroding maximum impaired broadening to the 1300mm.Under the situation of this sleeve wall 5A local damage, losing the support of both sides sleeve wall 5A and coming off will appear in the arch angle brick 11 as support arc top surface 8, thereby cause arc top surface 8 lose the arch angle brick 11 support and occur caving in, make the shut-down maintenance of having to of whole stove, thereby influence the bulk life time of normal production process and even hot metal mixer.
The utility model content
The purpose of this utility model is to provide a kind of hot metal mixer that is provided with novel iron notch, and the end face of iron notch can not come off yet behind the life-time service.
For achieving the above object, the hot metal mixer that is provided with novel iron notch of the present utility model comprises skin and the liner that links together, skin is a box hat, liner is for to build the body of heater that forms by laying bricks or stones by refractory materials, body of heater structurally includes arc furnace roof, furnace bottom, antetheca and rear wall, body of heater antetheca top outwards is provided with iron notch, furnace roof is provided with into Tie Kou, iron notch comprises end face and bottom surface, antetheca stretches out along the both sides, bottom surface to build by laying bricks or stones and forms the sleeve wall, described end face is the planar top surface of integral construction, described sleeve wall top and described end face support and connection.
Described end face is the one-piece construction by microdilatancy mould material casting.
The utlity model has following advantage:
1. the utility model is simple in structure, and is easy to use.End face is the planar top surface of integral construction, is convenient to construction, the end face obscission that can not take place in the past to occur when the local damage of sleeve wall.
2. described end face is that the one-piece construction performance is good by microdilatancy mould material casting, the end face obscission that in the past occurred because of the local damage of sleeve wall can not occur.

Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is a structural representation of the present utility model;
Fig. 4 is the A-A sectional view of Fig. 3;
Fig. 5 is the vertical view of Fig. 4.
Embodiment
Extremely shown in Figure 5 as Fig. 3, the hot metal mixer that is provided with novel iron notch of the present utility model comprises skin and the liner that links together, skin is a box hat 1, liner is for to build the body of heater that forms by laying bricks or stones by refractory materials, body of heater structurally includes arc furnace roof 2, furnace bottom 3, antetheca 5 and rear wall 6, body of heater antetheca 5 tops outwards are provided with iron notch, furnace roof 2 is provided with into iron mouth 7, iron notch comprises end face 28 and bottom surface 9, antetheca 5 stretches out along the both sides, bottom surface to build by laying bricks or stones and forms sleeve wall 5A, described end face 28 is the planar top surface by the integral construction of the integrated poured moulding of microdilatancy mould material, described sleeve wall 5A top and 28 support and connection of described end face.
Claims (2)
1. be provided with the hot metal mixer of novel iron notch, comprise the skin and the liner that link together, skin is a box hat, liner is for to build the body of heater that forms by laying bricks or stones by refractory materials, body of heater structurally includes arc furnace roof, furnace bottom, antetheca and rear wall, body of heater antetheca top outwards is provided with iron notch, furnace roof is provided with into Tie Kou, iron notch comprises end face and bottom surface, antetheca stretches out along the both sides, bottom surface to build by laying bricks or stones and forms the sleeve wall, it is characterized in that: described end face is the planar top surface of integral construction, described sleeve wall top and described end face support and connection.
