Description
Technical field
The present invention relates to a kind of automatic flat material device of the electric arc furnaces produced for casting zirconia corundum fused cast refractories fusing.
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
Melted by 2000 DEG C of high temperature above, caused power consumption is huge during electric arc furnaces melts, 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 main factor of fused cast refractories shaping ratio height, and the principal element in terms of quality
One of, melting process is under conditions of every facility is matched, and the used time is most short, power consumption is minimum, feed liquid viscosity meets casting and required
It is only best melting process, melting process, which reaches ideal effect and needs table operative employee correctly to coordinate, can just send out melting process
Wave optimum efficiency.
Electric arc furnaces is made up of bell, center ovens, bottom body of heater three parts, and bell is provided with three electricity by graphite electrode
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
Anomaly in condition, treatment furnace, and must be through fire door during flat material.It is nearest with center of arc furnace position or each of three electrodes during charging
Position charging, it is therefore an objective to complete fusion process with most short time.When graphite electrode exports energy, nearest apart from electrode
Batch is by high temperature melting, and the slightly remote batch of distance can form a shelly, it is necessary to which table operative employee uses drill rod making
The raw material of no fusing is pushed to the nearest place of electrode by flat material instrument, it is therefore an objective to is accelerated under conditions of the consumption of equal power consumption
Burn-off rate.Flat material number requirement is ten minutes first times flat material after feeding, flat every 10 minutes afterwards to expect once.According in stove
State generally requires flat material not less than three times.The environment very severe of flat material, need 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 raw material is serious in condition of high temperature sintering in stove, the flat material used time will extend, and operative employee often has facial quilt
Burn, 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
It is lazy inevitable, frequently occur it is artificial reduce flat material time and flat material number, it is that power consumption increase, ratio of briquetting are unstable to cause consequence
Calmly, quality is unstable.The flat material mode of electric arc furnaces table operative employee and do industry method and urgently improve.
The content of the invention
For the above situation, to overcome the defect of prior art, the purpose of the present invention is just to provide a kind of electric arc furnaces fusing
Automatic flat material device, can effectively solve the problems, such as that electric arc furnaces puts down material automatically.
The technical scheme that the present invention solves is a kind of automatic flat material device of electric arc furnaces fusing, including middle part connected up and down
The electric arc furnace body for the upper opening that stove and bottom oven are formed and the bell for being arranged on the electric arc furnace body upper oral part, middle part
Stove front and rear sides are provided with symmetrical fire door, and center ovens front bottom end is provided with converter nose, and the center ovens top between two fire doors is set
The slip heat-insulation layer circumferentially slided along body of heater is equipped with, slides the first perforation that inside and outside insertion is provided with heat-insulation layer, the stove of center ovens
Second perforation corresponding with the first perforation is provided with body, slides heat-insulation layer in sliding process, the first perforation is worn with second
Hole is overlapping, form with drill rod front end relative to flat material access way, electric arc furnaces outer body is provided with and flat material access way
The drill rod of horizontal face, drill rod rear end are provided with rack, and the gear engaged, the rotation of gear and motor are provided with rack
Axle is connected, and forms the front-rear reciprocation movement structure of the flat material access way of drill rod disengaging.
Trapezoidal gliding mass is provided with the inside of the slip heat-insulation layer, is provided with the outer wall of center ovens corresponding with trapezoidal gliding mass
Ladder chute, form and slide heat-insulation layer along the circumferential gliding movement targeting structure in center ovens surface.
The slip heat-insulation layer is made up of graphite.
It is described slide heat-insulation layer by inner surface contacted with the outer surface of center ovens.
Structure novel and unique of the present invention, advantages of simple, easily production are easy to operate, realize electric arc furnaces and put down material automatically, automatic flat
Material substitutes artificial flat material, equals material effect far better than artificial, due to accelerating burn-off rate, substantially reduces power consumption, subtract simultaneously
Few injury of the high temperature to operative employee, it is not necessary to during flat material, by sliding the perforation of heat-insulation layer covering first, reduce electric arc furnace heat
Scatter and disappear, to improving the ratio of briquetting of product, stay in grade serves great role, and easy to use, effect is good, is on furnace structure
Innovation, have good social and economic benefit.
