Description
Technical field
The invention belongs to non-ferrous metal smelting furnace technical field, be specifically related to a kind of refractory brick erecting by overhang, further relate to base
Furnace roof masonry suspending method in this erecting by overhang.
Background technology
Jiangxi Copper group Guixi Smelter (hereinafter referred to as your smelting) tilting furnace workshop fixed anode furnace furnace roof masonry is former
The suspending way of design is: insert the hole of middle and upper part between refractory brick with heat-resisting round steel, hanger brick circle hooks, and then uses
Iron chains is connected with hanging screw rod, with single nut, hanging screw rod is positioned on hanging beam fastening simultaneously.Due to hook and spiral shell
Using iron chains to connect between bar, up activity space is unlimited, and stove heats up or in production process, masonry is heated and up expands, and leads
Cause masonry and form dislocation up and down, be susceptible to brick or partial collapse accident.Simultaneously during producing charging, charging vehicle easily hits
Hit furnace roof masonry, cause furnace roof masonry to occur loosening, masonry to the phenomenon that even collapses of arch, force stove take insulation or
Impaired position is overhauled by the measure of blowing out, and what impact produced is normally carried out.In the process of your smelting wound mark post, to stove
The requirement of the key indexs such as body operation, furnace life, ton copper refractory material unit consumption is more and more higher, owing to above-mentioned masonry structure is unreasonable and
The impact of the factors such as external force so that the stove phase after operation easily occur rubescent, burn, the thing such as collapse to leak cigarette, deformation even local
Therefore, it is impossible to realize consecutive production, can not meet existing Production requirement.
Summary of the invention
It is an object of the invention to improve the structural strength of furnace roof masonry, improve the service life of furnace roof masonry, it is provided that one
Plant refractory brick erecting by overhang, additionally provide a kind of simple and practical, effect significant 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, suspension rod, suspender member, hanging beam is inserted in suspension rod upper end, uses above hanging beam
Nut fastens, on the suspension rod below hanging beam equipped with a nut, and upwards expanding needed for leaving body of heater between nut and hanging beam
Gap, fastens in the hole of downrod lower end insertion suspender member and with nut, and described suspender member is about by long 540mm, wide 80mm, thick
It is bent into hook clip-like after the heat-resisting steel sheet and plate center boring of 10mm, is especially connected by connecting plate such as two pieces of hanging board upper ends, connecting plate center
Being provided with hole, the lower end of two pieces of hanging boards is equipped with the hook part bent inwards.
Optimizing further, also set up reinforcing plate between two pieces of hanging boards, to improve suspender member intensity, two pieces of hanging boards are put down
OK, between their hook part axisymmetricly.
Present invention also offers a kind of furnace roof masonry suspending method, the two sides, upper end of hanger brick are provided with groove, hanging
The middle and upper part of brick is provided with hole；When building by laying bricks or stones after shutdown maintenance formwork, by the hole between two pieces of hanger bricks just to and put into short
Round steel, hanger brick hung after puzzling by body of heater again with suspender member, and two hook part of suspender member are stuck in the groove of hanger brick
In, suspender member connects suspension rod by nut, inserts hanging beam with suspension rod during hanging, fastens with nut, hang on hanging beam
Fill a nut below drop in beam, and reserved body of heater upwards expands required gap；Finally will be positioned over hanging on furnace roof spandrel girder
The two ends firm welding of drop in beam.
The income effect of the present invention is: have employed the furnace lining structure that structural strength is bigger, heats up or production process at stove
In, due to the activity within the reserved confined space of hanging masonry, solve original design iron chains and connect suspender member activity space
Infinitely, unsteady defect；Furnace roof masonry after improvement bears the ability of mechanical impact, and resisting expands with heat and contract with cold causes deformation of masonry
Ability strengthened；The method of the present invention, improves the service life of furnace roof masonry so that furnace roof fire resisting material can be hard
Hold 2 long production cycles, decrease to dig and repair and sporadicly overhaul number of times, reduce fault rate, saved refractory material expense and inspection
Repair expense；The method of the present invention, improves furnace life, and the fixed anode furnace of your smelting is the average furnace of (2010～2012) before transformation
Being respectively 295,309.25,273.6 heats age, improved average furnace life (2013) is 339.33 heats, promotes substantially, warp
Ji remarkable benefit.
Accompanying drawing explanation
Fig. 1 is original design furnace roof suspending way.
Fig. 2 is furnace roof suspending way after improvement.
Fig. 3 is suspender member schematic diagram.
Figure is labeled as 1, high strength nut 2, hanging beam 3, suspension rod 4, suspender member 5, refractory brick 41, hanging board
