Abstract
The utility model discloses a kind of mineral hot furnace furnace shells, including furnace wall and expansion plate made of being enclosed as the welding of several coverboards, expansion plate includes both ends and the arch pars contractilis being connected between both ends, the coverboard welding adjacent with the two of furnace wall respectively of the both ends of expansion plate, arch pars contractilis radially outward the arching upward along furnace wall of expansion plate.The mineral hot furnace furnace shell, the expansion plate being connected between the adjacent coverboard in furnace wall two includes arch pars contractilis, and the flexible space of arch pars contractilis of expansion plate is big, furnace wall expansion, when expansion plate is by the larger power of pullling, the arch pars contractilis of expansion plate can pull power by straightening the deformation of trend to eliminate this, compared to the connecting plate that tradition is straight panel, its tensile property is more preferable, itself is not easy to crack, so that the connection between two coverboards of furnace wall is more reliable, service life is greatly prolonged.
Description
Technical field
The utility model relates to mineral hot furnace technical field, especially a kind of mineral hot furnace furnace shell.
Background technique
The main function of mineral hot furnace furnace shell is the refractory material for waling its liner, and in this, as molten bath, accommodates and constantly add
The furnace charge and molten metal solution entered, periodically releases metallic solution by converter nose.Mineral hot furnace furnace shell, including by several coverboard rivetings
Cylindric furnace wall made of weldering encloses.Mineral hot furnace in use, with in-furnace temperature raising, the refractory material of wall lining and
Furnace wall expansion, easily cracks the furnace wall of furnace shell.To solve the above problems, existing mineral hot furnace furnace shell, the usually two adjacent shells in furnace wall
Solid welding connecting plate between plate, connecting plate are the straight panel for being tightly attached to furnace wall coverboard, and the space of dilatation is small, though it can be risen in the short time
Connection reinforcement effect between two plate shells of furnace wall, but in the expansion of furnace wall long term high temperature or as degrees of expansion increases, connecting plate institute
It is pullled and is insisted in long and biggish situation, connecting plate itself is easily opened because that can not eliminate the biggish power of pullling by deformation
It splits, loses booster action, the reinforcing effect that can be played is limited.
Summary of the invention
The purpose of this utility model is to provide a kind of mineral hot furnace furnace shells.
For realization the purpose of this utility model, its technical solution is now described in detail: a kind of mineral hot furnace furnace shell, including by several
Furnace wall and expansion plate made of coverboard welding encloses, expansion plate includes that both ends and the arch being connected between both ends are stretched
Contracting portion, adjacent with the two of the furnace wall coverboard welding respectively of the both ends of expansion plate, the radial direction of the arch pars contractilis of expansion plate along furnace wall
It arches upward outward.
Further, the staggered reinforcing rib of several transverse and longitudinals is distributed in the coverboard outer surface of furnace wall.Add by the way that transverse and longitudinal is staggered
The setting of strengthening tendons keeps the structure of coverboard stronger, bigger because expanding the power that can be born.
Further, expansion plate is symmetrical arranged along two adjacent coverboard intersecting lenses.By the way that expansion plate to be symmetrical arranged, make its work
For two adjacent coverboard active force it is more balanced, will not crack because one end stress is excessive.
The utility model mineral hot furnace furnace shell, the expansion plate being connected between the adjacent coverboard in furnace wall two includes arch pars contractilis, is stretched
The flexible space of arch pars contractilis of contracting plate is big, furnace wall expansion, when expansion plate is by the larger power of pullling, the arch of expansion plate
Pars contractilis can pull power by straightening the deformation of trend to eliminate this, compared to the connecting plate that tradition is straight panel, tensile property is more
Good, itself is not easy to crack, so that the connection between two coverboards of furnace wall is more reliable, service life is greatly prolonged.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model mineral hot furnace furnace shell；
Fig. 2 is the overlooking structure diagram that the utility model mineral hot furnace furnace shell does not include reinforcing rib；
Fig. 3 is the structural schematic diagram of the expansion plate of the utility model mineral hot furnace furnace shell.
Specific embodiment
The specific embodiment of the utility model mineral hot furnace furnace shell is described in detail with reference to the accompanying drawing:
As shown in Figure 1 to Figure 3, a kind of mineral hot furnace furnace shell, including as several coverboards 11 welding enclose made of furnace wall 1, with
And expansion plate 2, expansion plate 2 include both ends 21 and the arch pars contractilis 22 being connected between both ends 21, the both ends of expansion plate 2
Coverboard 11 adjacent with the two of furnace wall 1 welds respectively in portion 21, radially outward the arching upward along furnace wall 1 of arch pars contractilis 22 of expansion plate 2.
The staggered reinforcing rib 12 of several transverse and longitudinals is distributed in 11 outer surface of coverboard of furnace wall 1.Expansion plate 2 is along two adjacent 11 intersecting lenses pair of coverboard
Claim setting.
The utility model mineral hot furnace furnace shell, the expansion plate 2 being connected between the adjacent coverboard 11 in 1 liang of furnace wall include arch pars contractilis
22, the flexible space of arch pars contractilis 22 of expansion plate 2 is big, and furnace wall 1 expands, and when expansion plate 2 is by the larger power of pullling, stretches
The arch pars contractilis 22 of contracting plate 2 can pull power by straightening the deformation of trend to eliminate this, compared to the connection that tradition is straight panel
Plate, tensile property is more preferable, itself is not easy to crack, so that the connection between two coverboards 11 of furnace wall 1 is more reliable, service life
It greatly prolongs.
The utility model mineral hot furnace furnace shell, to keep the structure of coverboard 11 stronger, the power that can be born is bigger, preferably, furnace
The staggered reinforcing rib 12 of several transverse and longitudinals is distributed in 11 outer surface of coverboard of wall 1；It, can and in order to which the connection end structure of coverboard 11 is stronger
Keep reinforcing rib 12 higher in the distribution density of 11 connecting pin of coverboard.
The utility model mineral hot furnace furnace shell, it is two more balanced in the active force of adjacent coverboard 11 to act on contracting plate 2, it will not
It cracks because one end stress is excessive, preferably, expansion plate 2 is symmetrical arranged along two adjacent 11 intersecting lenses of coverboard.
