Description
Technical field
The present invention relates to metal melting equipment field, more particularly to a kind of electric arc furnaces for being equipped with L-type water cooled furnace wall.
Background technology
Electric arc furnaces (electric arc furnace) is the high melt ore and metal generated using electrode arc
Electric furnace.Energy is concentrated very much when gas discharge forms electric arc, and arc area temperature is at 3000 DEG C or more.For smelting metal, electric arc furnaces ratio
Other converter technological flexibilities are big, can remove effectively the impurity such as sulphur, phosphorus, and furnace temperature is easy to control, and occupation area of equipment is small, fit
In the melting of superior alloy steel.The electric arc furnaces that casting smelting industry uses is equipped with furnace body bias area, due to the presence in eccentric area, makes
Bell is hanging close to the position in eccentric area with furnace body, and hanging furnace body is subjected to molten steel high temperature and burns and cause crackle, scaling loss, leakage for a long time
Water generates security risk, therefore has one group of water cooled furnace wall to carry out cooling protection to furnace body.
Traditional water cooled furnace wall is the vertical hanging babinet that thickness is used to be welded for the superposition of 5mm seamless steel pipes, is installed
It is connect, is merely able to furnace body one side cooling protection with furnace body by bolt in the inside of furnace body.The lower face of furnace body and bias
The junction of bell, because planform reason raw water cooling furnace wall cannot form cooling protection to it, so as to cause furnace body lower face
It is exposed for a long time directly to be burnt outside by molten steel high temperature, it eventually leads to furnace body cracking, form the tear leak of furnace body water tank, when serious
Because connection bolt scaling loss causes water cooled furnace wall to fall into stove in molten steel, security risk is brought to equipment use.
Invention content
The technical problems to be solved by the invention are to provide a kind of electric arc furnaces for being equipped with L-type water cooled furnace wall, solve
The safety 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 equipped with L-type water cooled furnace wall, including stove brick and the furnace body that is located on stove brick, under the stove brick
Side is equipped with tapping hole, and the furnace body is equipped with fire door, furnace body water tank and waste material electrode, and the furnace body is formed with eccentric area, described
Eccentric area upper end is equipped with eccentric area bell, and the furnace body is equipped with L-type water cooled furnace wall, and the L-type water cooled furnace wall is by vertical cavity
With transverse chambers body by integral forming, the inside connection of the vertical cavity and furnace body, the transverse chambers are shown consideration in eccentric area's bell
Lower end.
Further improvement lies in that the vertical cavity and lateral 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 again with furnace body water tank, for providing cooling circulating water.
Further improvement lies in that the vertical inside cavity is equipped with several cavity partition boards, the cavity partition board is lateral simultaneously
Row's setting.
Further improvement lies in that it is each formed with circulating water channel, the cycle in the end point of each cavity partition board
Aquaporin has connected the upper and lower side space of cavity partition board.
Further improvement lies in that the end that the circulating water channel on adjacent two pieces of cavity partition boards is in opposite direction
Place.
Further improvement lies in that the vertical cavity is equipped with connector, vertical cavity is fixed on furnace body by connector
Inside.
The beneficial effects of the invention are as follows：
1) the normal productive temp of electric arc furnaces is stablized, and equipment failure rate reduces.A kind of L-type water cooling stove provided by the invention
Wall failure rate is substantially zeroed, and advantageous guarantee is provided to normal melting process；Meanwhile the improvement of water cooled furnace wall structure is to repair
Bring great convenience, vertical arc box body be changed to L-type water cooled furnace wall, body structure is simple, shell be all arcwall face or
Plane, when welding is plugged a hole, no matter loophole appears in any position, maintenance personal can facilitate processing in time, and easily observation is easily repaiied
It mends.
2) service life of equipment lengthens, and maintenance cost is reduced.The water cooled furnace wall used before is to use thickness seamless for 5mm
Steel pipe manufacturing forms, 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 steel of the thickness for 16mm
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 "
Part protects furnace body lower face, and furnace body is made no longer directly to be burnt by high temperature.Compared to water cooled furnace wall before, new design invention
L-type water cooled furnace wall does not all need to replace under normal usage, 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, connection fixing bolt is strongly fortified under the cooling protection of L-type part, eliminates water cooled furnace wall babinet and falls into molten steel
Security risk, make itself safe to use being protected for equipment.
