Abstract
The utility model relates to a package roaster nozzle protector in middle of conticaster belongs to metallurgical industry conticaster equipment and technology technical field. The technical scheme is as follows: be equipped with on middle-packing apron (4) and toast the hole with roaster nozzle (1) matched with, roaster nozzle (1) sets up in the toasting hole of middle-packing apron (4), and high temperature resistant castable (3) are poured between roaster nozzle (1) and middle-packing apron (4), and the thickness of high temperature resistant castable (3) is the same with the thickness of middle-packing apron (4), and roaster nozzle (1) is fixed in high temperature resistant castable (3) through flange (2) and bolt (6). The utility model has the advantages that: not only can protect the roaster nozzle effectively, prolong the life of roaster nozzle, but also can be better the sealed middle package, avoid flame to leak, reduce the middle package and toast the heat loss of in-process, improve the efficiency of toasting of package.
Description
Technical Field
The utility model relates to a package roaster nozzle protector in middle of conticaster belongs to metallurgical industry conticaster equipment and technology technical field.
Background
The tundish is for short known by middle package, when the tundish is baked, the burner of the baking device directly extends into the tundish through the baking hole on the tundish cover plate, and the tundish is baked through the burning flame. When baking, the temperature of the tundish is over 1000 ℃, and the burner of the baking device is made of carbon steel, so that the burning loss of the burner is easy to cause serious damage, and the service life of the burner is influenced; in addition, after the roaster nozzle burns out, the tundish baking flame can leak out from the roaster nozzle burning out part, so that a large amount of heat loss is caused, the tundish baking efficiency is reduced, and the damage to the equipment in the region is large.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a package roaster nozzle protector in middle of conticaster can not only prolong the life of roaster nozzle, and the package in the middle of can also be better sealed reduces the heat loss that the package toasted the in-process in the middle of, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
the utility model provides a package roaster nozzle protector in middle of conticaster contains roaster nozzle, flange, the refractory castable, well package apron and bolt, well package be equipped with on the apron with roaster nozzle matched with toast the hole, the roaster nozzle sets up in the toast of well package apron downthehole, the refractory castable pouring is between roaster nozzle and well package apron, the thickness of refractory castable is the same with well package apron thickness, the roaster nozzle passes through flange and bolt fastening in the refractory castable.
The flange is welded on the burner of the roaster and is fixed on the high-temperature resistant castable through bolts.
The flange is embedded in the high-temperature resistant casting material.
The upper end face of the flange and the upper end face of the middle ladle cover plate are on the same horizontal plane.
Adopt the utility model discloses, during well package toasts the operation, because the refractory castable material forms sealedly between roaster nozzle and well package apron to avoid flame to cause the scaling loss to the nozzle, stopped the heat loss that flame leakage caused.
The utility model has the advantages that: not only can protect the roaster nozzle effectively, prolong the life of roaster nozzle, but also can be better the sealed middle package, avoid flame to leak, reduce the middle package and toast the heat loss of in-process, improve the efficiency of toasting of package.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a partial schematic view of the present invention;
FIG. 3 is a top view of FIG. 2;
in the figure: 1. a roaster burner; 2. a flange; 3. high-temperature resistant castable; 4. a middle ladle cover plate; 5. a flame; 6. and (4) bolts.
Detailed Description
The invention will be further explained by way of example with reference to the accompanying drawings.
Referring to the attached drawings 1-3, a package roaster nozzle protector in middle of conticaster, contain roaster nozzle 1, the flange 2, high temperature resistant castable 3, well package apron 4 and bolt 6, be equipped with on the well package apron 4 with roaster nozzle 1 matched with toast the hole, roaster nozzle 1 sets up in the toasting of well package apron 4 downthehole, pouring of high temperature resistant castable 3 is between roaster nozzle 1 and well package apron 4, the thickness of high temperature resistant castable 3 is the same with the thickness of well package apron 4, roaster nozzle 1 is fixed in high temperature resistant castable 3 through flange 2 and bolt 6.
In this embodiment, referring to fig. 1, 2 and 3, the flange 2 is embedded in the refractory castable 3, the upper end surface of the flange 2 and the upper end surface of the tundish cover plate 4 are on the same horizontal plane, the flange 2 is fixed by four bolts 6, and the burner port of the roaster burner 1 is flush with the lower end surface of the tundish cover plate 4.
When the roaster toasts, because high temperature resistant pouring material 3 wraps up roaster nozzle 1, can avoid flame 5 to cause the scaling loss to nozzle 1. Meanwhile, the flange 2, the pouring material 3 and the middle ladle cover plate 4 are embedded, so that the leakage of flame 5 can be effectively isolated, the heat loss is avoided, and the equipment in the area is protected from being burnt.
