Description
Technical field
The invention belongs to non-ferrous metal smelting furnace technical fields, and in particular to a kind of refractory brick erecting by overhang further relates to base
In the furnace roof masonry suspending method of the erecting by overhang.
Background technology
Jiangxi Copper group Guixi Smelter（Hereinafter referred to as your smelting）The fixed anode furnace furnace roof masonry in tilting furnace workshop is former
The suspending way of design is：The hole of middle and upper part is inserted between refractory brick with heat-resisting round steel, hanger brick is hooked with circle, then used
Iron chains is connected with hanging screw rod, while hanging screw rod being positioned on hanging beam with single nut and is fastened.Due to hook and spiral shell
It is connected using iron chains between bar, up activity space is unlimited, and in stove heating or production process, masonry is heated up to be expanded, and is led
It causes masonry to form dislocation up and down, is easy to happen brick or partial collapse accident.Simultaneously during producing charging, charging vehicle is easily hit
Hit furnace roof masonry, cause furnace roof masonry occur loosen, masonry to arch even collapse the phenomenon that, force stove take heat preservation or
Impaired position is overhauled in the measure of blowing out, influences being normally carried out for production.In the process that mark post is created in your smelting, to stove
The requirement of the key indexes such as body operation, furnace life, ton copper refractory material unit consumption is higher and higher, since above-mentioned masonry structure is unreasonable and
The influence of the factors such as external force so that stove after operation the phase easily occur it is rubescent, burn, leakage cigarette, the things such as collapse for deformation even part
Therefore consecutive production is cannot achieve, have been unable to meet existing production requirement.
Invention content
It is an object of the invention to improve the structural strength of furnace roof masonry, the service life of furnace roof masonry is improved, provides one
Kind refractory brick erecting by overhang additionally provides a kind of simple and practical, effective furnace lining improved method.
In order to achieve the above object, the present invention adopts the following technical scheme that：
A kind of refractory brick erecting by overhang, including hanging beam, sunpender, suspender member, hanging beam is inserted into sunpender upper end, on hanging beam
Face is fastened with nut, a nut is housed, there are upward swollen needed for furnace body between nut and hanging beam on the sunpender below hanging beam
Swollen gap, downrod lower end are inserted into the hole of suspender member and are fastened with nut, and the suspender member is wide about by long 540mm
It is bent into hook clip-like after the heat-resisting steel sheet and plate center drilling of 80mm, thick 10mm, such as two pieces of hanging board upper ends are connected by connecting plate especially, even
Plate center is equipped with hole, and the lower end of two pieces of hanging boards is equipped with the hook part to bend inwards.
It advanced optimizes, reinforcing plate is also set up between two pieces of hanging boards, to improve suspender member intensity, two pieces of hanging boards are flat
It goes, between their hook part axisymmetricly.
The present invention also provides a kind of furnace roof masonry suspending method, the upper end two sides of hanger brick are equipped with groove, hanging
The middle and upper part of brick is equipped with hole；When being built by laying bricks or stones after shutdown maintenance formwork, by the hole face between two pieces of hanger bricks and it is put into short
Round steel, furnace body again hang hanger brick with suspender member after puzzling, and two hook parts of suspender member are stuck in the groove of hanger brick
Interior, suspender member connects sunpender by nut, is inserted into hanging beam with sunpender when hanging, is fastened, hung with nut in the upper surface of hanging beam
A nut is filled below drop in beam, and reserved furnace body expands required gap upwards；Hanging on furnace roof spandrel girder will be finally positioned over
The both ends firm welding of drop in beam.
The present invention income effect be：The furnace lining structure for using structural strength bigger, in stove heating or production process
In, due to the activity within the reserved confined space of hanging masonry, solve former design iron chains connection suspender member activity space
Infinitely, unsteady defect；Improved furnace roof masonry bears the ability of mechanical impact, and resistance expands with heat and contract with cold and causes deformation of masonry
Ability reinforced；The method of the present invention, improves the service life of furnace roof masonry so that furnace roof fire resisting material can be hard
2 long production periods are held, reduces digging and repaiies and sporadicly overhaul number, reduce failure rate, saved refractory material expense and inspection
Repair expense；The method of the present invention, improves furnace life, the fixed anode furnace of your smelting is before transformation（2010~2012 years）Average furnace
Age is respectively 295,309.25,273.6 heats, improved average furnace life（2013）For 339.33 heats, apparent, warp is promoted
Ji remarkable benefit.
Description of the drawings
Fig. 1 is former design furnace roof suspending way.
Fig. 2 is furnace roof suspending way after improving.
Fig. 3 is suspender member schematic diagram.
Label is, high strength nut 2, hanging beam 3, sunpender 4, suspender member 5, refractory brick 41, hanging board 42, connects in figure
Plate 43, hook part 44, reinforcing plate.
Specific embodiment
The present invention is furtherd elucidate below in conjunction with the accompanying drawings.
The intrinsic Fig. 1 suspending ways of fixed anode furnace furnace roof furnace lining are changed to Fig. 2 by a kind of refractory brick erecting by overhang
Suspending way, the material of furnace roof refractory brick is changed to Semi bonded magnesia chrome brick, hanger brick in Fig. 2（The refractory brick of hanging）
Upper end two sides be equipped with groove, the middle and upper part of hanger brick is equipped with hole；The middle and upper part of common refractory brick 5 is equipped with hole, corresponding
Ground devises suspender member 4, and the hanging 4 includes being similar to two pieces of hanging boards 41, and the upper end of two pieces of hanging boards 41 passes through connecting plate 42
Connection, 42 center of connecting plate are equipped with hole, and the lower end of two pieces of hanging boards 41 is equipped with the hook part 43 to bend inwards.More particularly
It is to also set up reinforcing plate 44 between two pieces of hanging boards 41, with lifting pendant intensity, two pieces of hanging boards are parallel, their hook part
Between 43 axisymmetricly.Erecting by overhang is formed by hanging beam 2, sunpender 3, suspender member 4,3 upper end of sunpender is inserted into hanging beam 2 and with high
Intensity nut 1 fastens, and 3 lower end of sunpender is inserted into the hole of suspender member 4 and is fastened up and down with nut.
After above-mentioned erecting by overhang, furnace roof masonry suspending method is improved, by two when being built by laying bricks or stones after shutdown maintenance formwork
Block hanger brick（Including common refractory brick 5）Between hole face and be put into short round steel, furnace body puzzle after again with suspender member 4 to hanging
Brick to be hung to be hung, two hook parts of suspender member 4 are stuck in the groove of hanger brick, and suspender member 4 connects sunpender 3 by nut,
The hanging beam 2 of top being inserted into sunpender 3 when hanging and being fastened with high strength nut 1, it is reserved certain that one is filled below hanging beam 2
Expansion clearance nut；The both ends firm welding of the hanging beam on furnace roof spandrel girder 2 will be finally positioned over.
Set in the suspender member 4 of the present invention there are two hanging board, and in shape is grabbed between the two, intensity is high, with hanger brick it
Between be firmly combined with, using high strength nut connection suspender member 4 and sunpender 3, sunpender 3 will not shake with hanging beam 2, solve original and set
Meter unlimited, unsteady defect with iron chains connection suspender member activity space；Improved furnace roof masonry bears the energy of mechanical impact
