Description
Technical field
The utility model is related to be used for a kind of two-door electric arc furnaces with safeguard function of casting zirconia corundum fused cast refractories production.
Background technology
Zirconia-corundum refractory brick production key link is batch zircon sand, alumina powder and a small amount of soda ash, in electric arc furnaces
By 2000 DEG C or more high temperature meltings, the power consumption that electric arc furnaces generates during melting is huge, and the power consumption of one ton of feed liquid of fusing is 2200 °
To 2600 degree, power consumption is a larger cost in fused cast refractories production process.
Electric arc furnaces melting process is the principal element in terms of the main factor and quality of fused cast refractories molding ratio height
One of, melting process is under conditions of the every facility of matching, and the used time is most short, power consumption is minimum, feed liquid viscosity meets casting requirement
It is only best melting process, melting process, which reaches ideal effect table operative employee is needed correctly to coordinate, can just send out melting process
Wave optimum efficiency.
Electric arc furnaces is made of bell, center ovens, bottom furnace body three parts, and there are three the electricity by graphite electrode for bell setting
Pole hole, oxygen rifle enters the oxygen rifle hole of solution in stove when having oxygen blast.Center ovens are correspondingly arranged on fire door, and effect is shape in observation stove
Abnormal phenomenon and necessary fire door during flat material in condition, treatment furnace.It is nearest with center of arc furnace position or each of three electrodes during charging
Position charging, it is therefore an objective to the shortest time completion fusion process.When graphite electrode exports energy, nearest apart from electrode
Batch by high temperature melting, the slightly remote batch of distance can be formed one it is shelly-shaped, need what table operative employee was made using drill rod
The raw material of no fusing is pushed to the nearest place of electrode by flat material tool, it is therefore an objective to be accelerated under conditions of the consumption of equal power consumption
Burn-off rate.Flat material number requires to be ten minutes first times flat material after feeding, flat every 10 minutes later to expect once.According in stove
State generally requires flat material not less than three times.The environment very severe of flat material needs to open fire door, hyperthermia radiation temperature when putting down material
It can reach on 50 DEG C when apart from two meters of electric arc furnaces, higher from the nearlyer temperature of fire door, operative employee needs to dress high temperature resistance protection
Clothes, goggles, when condition of high temperature sintering is serious, the flat material used time will extend raw material, and operative employee often has facial quilt in stove
It burns, accidentally have the strong light pierce eyes of electric arc, seriously endanger the health of operative employee.Operative employee's steals under the conditions of this
Lazyness is inevitable, frequently occurs artificial reduction and puts down and expect that the time expects number with flat, it is power consumption increase, ratio of briquetting shakiness to lead to consequence
Calmly, quality is unstable.It the flat material mode of electric arc furnaces table operative employee and does industry method and urgently improves.
Utility model content
For the above situation, to overcome the defect of the prior art, the purpose of the utility model is just to provide one kind with anti-
The two-door electric arc furnaces of protective function, can effectively solve the problem of electric arc furnaces put down material open fire door when temperature it is excessively high radiate it is serious.
The technical solution that the utility model solves is a kind of two-door electric arc furnaces with safeguard function, including being connected up and down
Center ovens and the electric arc furnace body of upper opening that forms of bottom oven and be arranged on the stove of the electric arc furnace body upper oral part
Lid, which is characterized in that be provided with the inside and outside window penetrated through in center ovens, the both sides of window are respectively arranged with corresponding with window
The insulated door peace material observation door of overturning, being respectively arranged with observation panel peace material hole on flat material observation door, on observation panel covered with
The glass of perspective.
Flat material observation first loose-leaf of the door through window side is connected to the side of window, and insulated door is another through window
Second loose-leaf of side is connected to the opposite side of window；In the insulated door peace material observation door, when one of which is placed in window,
Another one, which flips outward, is located at this outside of electric arc furnaces.
The utility model structure novel is unique, advantages of simple, easily produces, easy to operate, and insulated door is opened when putting down material, closes flat
Material observation door, flame conditions are observed by observation panel, flat material hole are passed through to be avoided after opening fire door to material is put down in stove by drill rod
Heat radiation of the high temperature to operative employee, reduces injury of the high temperature to operative employee, while furnace heat scatters and disappears and greatly reduces during flat material,
To improving the ratio of briquetting of product, stay in grade plays great role, and easy to use, effect is good, is the wound on furnace structure
Newly.

Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing.
As shown in figures 1 to 6, the utility model includes the upper opening that center ovens 1a connected up and down and bottom oven 1b is formed
Electric arc furnace body and be arranged on the bell 2 of the electric arc furnace body upper oral part, which is characterized in that be provided on center ovens 1a
The window 5 of inside and outside perforation, the both sides of window 5 are respectively arranged with and 8 peace material observation door of the insulated door of the corresponding overturning of window
6, flat material is observed and 9 peace material hole 11 of observation panel is respectively arranged on door 6, the glass 10 covered with perspective on observation panel 9.
To ensure using effect, 3 electrode holes 3 and an oxygen blast hole 4 are respectively arranged on the bell 2.
The glass 10 is dark glass.
The flat material observation first loose-leaf 7a of the door 6 through 5 side of window is connected to the side of window, and insulated door 8 is through window
Second loose-leaf 7b of 5 opposite sides of mouth is connected to the opposite side of window；In the 8 peace material observation door 6 of insulated door, one of which is put
When in window 5, another one, which flips outward, is located at this outside of electric arc furnaces.
The flat material hole 11 is located at the center that flat material observes door 6, and observation panel 9 is located at the underface in flat material hole 11.
The observation panel 9 is rectangle, long 200mm, wide 150mm.
The 8 peace material observation door 6 of insulated door is made of thermal insulation material.
When the utility model is used, normal melt process insulated door 8 is placed in window 5, puts down material observation 6 turned-out indexing of door
It in this outside of electric arc furnaces, when needing flat material, flips outward and opens insulated door, flat material observation door is closed in inwardly overturning, sees flat material
Cha Men is placed in window 5, and insulated door is located at this outside of electric arc furnaces, and flame conditions are observed by observation panel, is passed through by drill rod flat
Expect that hole to material is put down in stove, avoids heat radiation of the high temperature to operative employee after opening fire door, reduce injury of the high temperature to operative employee, change
It has been apt to the working environment of worker, while furnace heat scatters and disappears and greatly reduces during flat material, it is steady to the ratio of briquetting, the quality that improve product
Surely great role is played, easy to use, effect is good, is the innovation on furnace structure.
