Abstract
The utility model discloses a blast furnace main iron runner steel shell structure which comprises a steel shell, wherein anchor flukes are uniformly spaced on the outer wall of the steel shell; a 100mm-thick fiber felt is hung on the anchor flukes; the outer part of the fiber felt is wrapped by a refractory castable layer; and a protection shell is arranged at the outer side of the refractory castable layer. The hung 100mm-thick fiber felt can effectively remove the stress of a main runner steel shell at high temperature and thermal expansion of castable; by pouring the castable into other gaps outside the main runner steel shell, the main runner steel shell can be effectively prevented from inclining greatly toward the two outer sides so as to reduce the serious deformation of the main runner steel shell and improve the service life of the main runner steel shell and the safety coefficient of iron.
Description
Technical field
The utility model relates to a kind of main trough of blast furnace box hat structure.
Background technology
The main trough of blast furnace box hat is original design is five joints, putting into tap drain simply welds, box hat has 150mm High-Alumina insulating brick to add the 56mm Lowweight Refractory Castable outward, in use, main trough steel casing is due under the stress that expands with heat and contract with cold at mould material and box hat body, it is serious that box hat opens after strain to two outsides, and the crack, many places appears in the box hat weld, has a strong impact on the work-ing life of main iron hook box hat, reduce the logical iron safety coefficient of tap drain, have certain safety in production hidden danger.
Summary of the invention
The purpose of this utility model is to provide a kind of main trough of blast furnace box hat structure, can effectively eliminate box hat stress and deformation, extends box hat work-ing life.
The purpose of this utility model is to realize like this; a kind of main trough of blast furnace box hat structure; comprise box hat; uniform interval is arranging anchor fluke on the outer wall of box hat; hanging the thick fibrefelt of 100mm on anchor fluke; the outside of fibrefelt coats the refractory casting bed of material is being set, and is protective shell outside the refractory casting bed of material.
The fibrefelt that hangs 100mm effectively the removal main trough steel casing at the stress of high temperature and mould material heat expansion, outer all the other spaces of main trough steel casing can prevent effectively that with the mould material cast main trough steel casing to two outsides, larger inclination occuring, thereby it is serious to reduce the main trough steel casing distortion, improves the safety coefficient of main trough steel casing work-ing life and logical iron.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is main TV structure schematic diagram of the present utility model.
Embodiment
A kind of main trough of blast furnace box hat structure as shown in Figure 1, comprises box hat 2; uniform interval is arranging anchor fluke 1 on the outer wall of box hat 2; hanging the thick fibrefelt of 100mm 3 on anchor fluke 1, the outside of fibrefelt 3 coats the refractory casting bed of material 4 is being set, and the refractory casting bed of material 4 outsides are protective shell.The fibrefelt 3 that hangs 100mm effectively removal main trough steel casing 2 at the stress of high temperature and mould material heat expansion, outer all the other spaces of main trough steel casing can prevent effectively that with the mould material cast main trough steel casing to two outsides, larger inclination occuring, thereby reduce the serious problem of main trough steel casing distortion, improve the safety coefficient of main trough steel casing work-ing life and logical iron.
