Description
Technical field
The present invention relates to metal melting equipment field, more particularly to a kind of electric arc furnaces for being provided with L-type water cooled furnace wall.
Background technology
Electric arc furnaces (electric arc furnace) is to utilize high melt ore and metal caused by electrode arc
Electric furnace.Energy is concentrated very much when gas discharge forms electric arc, and arc area temperature is more than 3000 DEG C.For smelting metal, electric arc furnaces ratio
Other converter technological flexibilities are big, can effectively remove impurity, the furnace temperature such as desulfuration, phosphorus and be easily controlled, and occupation area of equipment is small,
Melting suitable for superior alloy steel.The electric arc furnaces that casting smelting industry uses is provided with body of heater bias area, due to depositing for eccentric area
, make bell hanging close to the position in eccentric area with body of heater, hanging body of heater be subjected to for a long time molten steel high temperature burn and cause crackle,
Scaling loss, leak, potential safety hazard is produced, therefore there is one group of water cooled furnace wall to carry out cooling protection to body of heater.
Traditional water cooled furnace wall is the vertical hanging casing for using thickness to be welded for the superposition of 5mm seamless steel pipes, and it is installed
It is connected, is merely able to body of heater one side cooling protection with body of heater by bolt in the inner side of body of heater.The lower surface of body of heater and bias
The junction of bell, because planform reason raw water cooling furnace wall can not form cooling protection to it, so as to cause body of heater lower surface
It is exposed for a long time directly to be burnt outside by molten steel high temperature, ultimately result in body of heater cracking, form the tear leak of body of heater water tank, seriously
When because connecting bolt scaling loss cause water cooled furnace wall fall into stove in molten steel, bring potential safety hazard to equipment use.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of electric arc furnaces for being provided with L-type water cooled furnace wall, and it is solved
The security that equipment uses is improved in the protection defect problem at the position in the water cooled furnace wall of traditional structure.
The technical problems to be solved by the invention are realized using following technical scheme：
A kind of electric arc furnaces for being provided with L-type water cooled furnace wall, including stove brick and the body of heater that is located on stove brick, the stove brick
Lower section is provided with tapping hole, and the body of heater is provided with fire door, body of heater water tank and waste material electrode, and the body of heater is formed with eccentric area, institute
State eccentric area upper end and be provided with eccentric area's bell, the body of heater is provided with L-type water cooled furnace wall, and the L-type water cooled furnace wall is by vertical chamber
Body and transverse chambers body by integral forming, the inner side of the vertical cavity and body of heater are connected, and the transverse chambers are shown consideration in eccentric area's stove
The lower end of lid.
Further improvement is that the vertical cavity and horizontal inside cavity are hollow-core construction, and vertical cavity and horizontal stroke
It is interconnected to inside cavity, the L-type water cooled furnace wall connects with body of heater water tank again, for providing cooling circulating water.
Further improvement is that the vertical inside cavity is provided with several cavity dividing plates, the cavity dividing plate is horizontal simultaneously
Row is set.
Further improvement is that it is each formed with circulating water channel, the circulation in the end of each cavity dividing plate
Aquaporin has connected the upper and lower side space of cavity dividing plate.
Further improvement is that the termination that the circulating water channel on adjacent two pieces of cavity dividing plates is in opposite direction
Place.
Further improvement is that the vertical cavity is provided with connector, vertical cavity is fixed on body of heater by connector
Inner side.
The beneficial effects of the invention are as follows：
1) the normal productive temp of electric arc furnaces obtains stabilization, and equipment failure rate reduces.A kind of L-type water cooling provided by the invention
Furnace wall fault rate is substantially zeroed, and favourable guarantee is provided to normal melting process；Meanwhile the improvement of water cooled furnace wall structure is given
Maintenance is brought great convenience, and vertical arc box body is changed into L-type water cooled furnace wall, and body structure is simple, and shell is all arc
Face or plane, when welding is plugged a hole, no matter leak appears in any position, maintenance personal can facilitate processing in time, easily see
Examine easy repairing.
2) service life of equipment is lengthened, and maintenance cost is reduced.The water cooled furnace wall used before be use thickness for 5mm without
Seam steel pipe manufacturing is formed, and tube wall is too thin to be easily damaged, and repairing is difficult, and L types water cooled furnace wall is all to use Q235 of the thickness for 16mm
Steel plate makes, and the place of all connections is all using single face welding and double face shaping, full weld welded seal, it is often more important that its " L
Type " partly protects body of heater lower surface, body of heater is no longer directly burnt by high temperature.Compared to water cooled furnace wall before, new design
The L-type water cooled furnace wall of invention under normal usage, need not all be changed within several years.
3) equipment itself is safe to use is protected.Reduce the leak peace for even avoiding water cooled furnace wall in L-type water cooled furnace wall
Full hidden danger, the bolt that is connected is strongly fortified under the cooling protection of L-type part, eliminates water cooled furnace wall casing and falls into molten steel
In potential safety hazard, make itself safe to use being protected for equipment.
