Description
Technical field
The utility model relates to electric furnace steel making fields.
Background technique
Electric furnace steel making is to be made steel using electric energy as heat source, and electric furnace is by furnace body, tilting equipment, electrical equipment, electrode
Elevator and cooling system composition.Furnace body includes bell, furnace wall and several parts of furnace bottom.Wherein furnace lid be with electrode hole and
The spheric structure of exhaust smoke hole, outer ring portion claim main bell, and middle section claims small furnace cover（Also known as trigonum）, bell can when charging
It removes.Electric furnace smelting process is extremely complex, and triangle zone prefab condition is very harsh.Furnace lid in use, can be because
Electric arc heated, tapping and furnace lid, which rotate to charge outside furnace, causes rapid heat cycle, so that bell is generated thermal stress and causes working face
It peels off；Loosening, slump can be easily caused to eventually lead to replacement furnace under conditions of no external force supports because bell is under Gravitative Loads
Lid.
Summary of the invention
Technical problem to be solved in the utility model is：Thermal shock resistance and the bell for how improving furnace lid are whole
The fastness of structure, reduction cracks because rapid heat cycle generates and because bell is under Gravitative Loads, under conditions of no external force supports
Caused by loosen, slump.
Technical solution used by the utility model is：A kind of furnace lid, bottom area are less than the rotary table of upper top area
Shape lid（2）Side has from upper notch diagonally downward（8）, lid（2）There is upper reinforcing bar stiffening ring in side on inside（1）Lower periphery side
There is lower reinforcing bar stiffening ring（10）, upper reinforcing bar stiffening ring（1）With lower reinforcing bar stiffening ring（10）Pass through reinforcing bar rib（7）Connection, upper steel
Muscle stiffening ring（1）Lower reinforcing bar stiffening ring（10）With three pieces of reinforcement connecting plates each other in 120 degree of angles（4）Connection, every piece of reinforcement connect
Fishplate bar（4）Top be welded with and with holes play hanging piece（3）, three pieces of reinforcement connecting plates（4）There is electrode hole in the space surrounded each other
（6）, electrode hole（6）With every piece of reinforcement connecting plate（4）Between trigonum all poured refractory material.
As a kind of preferred embodiment：Three electrode hole cross sections center of circle is wired to equilateral triangle.
The utility model has the beneficial effects that:The utility model is by using the welding reinforcement connecting plate between electrode hole
（Reinforcing bar etc.）And bell surrounding increases by two circles（Upper reinforcing bar stiffening ring and lower reinforcing bar stiffening ring）A variety of linking connections such as reinforcing bar, from
And the whole binding ability of refractory material and steel construction is improved, sound construction does not crack, while improving the anti-thermal shock of bell
Property, to improve the service life of bell.

Specific embodiment
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model is a kind of electric furnace cover being mounted on electric furnace, and electrode hole 6 is used
In placing electrode, electric furnace cover is made by way of first making framework of steel reinforcement and then pouring filling of refractory material, in fire proofed wood
Before material pours filling, electrode casement is placed in the position in counter electrode hole, there is punching block in outside.Since furnace lid is in use process
In, rapid heat cycle caused by charging can be rotated to outside furnace because of electric arc heated, tapping and furnace lid, so that bell is generated thermal stress and caused
Working face peels off；Loosening, slump can be easily caused to eventually lead to more under conditions of no external force supports because bell is under Gravitative Loads
Change bell.Then the utility model is completed electric furnace cover by one framework of steel reinforcement of production and is poured, the bottom area of electric furnace cover is less than
2 side of round table-like lid of upper top area has from upper notch 8 diagonally downward（Angle generally with top surface on steel construction lid at
76 degree）, upper side has upper 1 lower periphery side of reinforcing bar stiffening ring to have a lower reinforcing bar stiffening ring 10 inside lid 2, upper reinforcing bar stiffening ring 1 and under
Reinforcing bar stiffening ring 10 is connected by reinforcing bar rib 7, upper reinforcing bar stiffening ring 1 and lower reinforcing bar stiffening ring 10 with each other in 120 degree of angles
Three pieces of reinforcement connecting plate 4 connections, the top of every piece of reinforcement connecting plate 4 are welded with a hanging piece 3 with holes, three pieces of reinforcement connecting plates 4
There is electrode hole 6 in the space surrounded each other, refractory material, three electricity have all been poured between electrode hole 6 and every piece of reinforcement connecting plate 4
The pole slot cross section center of circle is wired to equilateral triangle.
