Description
Technical field
The utility model belongs to the technical field of utilizing electromagnetic induction heating thawing or metal smelting, particularly a kind of stool of the plumbous coreless-type induction furnace of large-scale refining of fast changeable metallic crucible.
Background technology
Electric induction furnace heating is by electromagnetic induction principle, directly (metal) crucible and (or) be heated metal inside and produce eddy current, can in the short time rated power be used for METAL HEATING PROCESS at the utmost point.Because energy refines plumbous crucible and adopts metal material again by the space electromagnetic conversion, refines the electric conversion efficiency height of plumbous coreless-type induction furnace, is much higher than the resistance heated mode; Electric stove integral equipment high efficiency, energy-conservation, the life-span is long.
Compare with fuel (oil firing, burning gas) stove, adopt the coreless-type induction furnace molten lead to have the following advantages:
(1) scaling loss of lead pig and metal is little;
(2) easy control of temperature of metal, metal smelting quality height;
(3) firing rate is fast, produces flexible;
(4) environmental pollution is little, good operation conditions.
Refining (melting) plumbous coreless-type induction furnace equipment is made of machinery and electric two parts, and mechanical part comprises body of heater, water-cooled frame etc.Body of heater is the core of electric furnace, has fixed and the tilting-type structure, is made up of inductor, yoke, grate etc.Consider the plumbous low-melting-point metal that is, furnace lining adopts metallic crucibles such as cast steel, stainless steel, and lining durability is long, the efficient height.Electric part is made up of furnace transformer, compensation condenser and balanced capacitor, paralleing reactor, switch board etc.
The plumbous coreless-type induction furnace of large-scale refining, be meant here furnace volume be 10t and more than, the capacity that is meant especially is 30t, 50t, 120t, 150t, 200t, the plumbous coreless-type induction furnace of refining that furnace diameter 1000mm is above.
The conventional fixed formula is refined plumbous coreless-type induction furnace body of heater and is made up of yoke, metallic crucible, inductor, filling fire resisting material, the prefabricated refractory material of furnace bottom and grate.The first ramming of partially filled refractory material is on the prefabricated refractory material of furnace bottom, and metallic crucible places on the filling fire resisting material again.Fill up filling fire resisting material around the metallic crucible.
Large-scale molten lead coreless-type induction furnace, crucible itself is heavy, adds adhesion and residual lead metal, and the crucible capacity is just heavier.In case prefabricated refractory material of molten metal that spills and furnace bottom and refractory material all around are bonding, make crucible and filling fire resisting material and body of heater in aggregates, it is just very difficult to take out the replacing crucible.General crane crane capacity is not enough, even the crane of enough crane capacities is arranged, hangs out metallic crucible by force and also might damage the electric furnace body, and electric furnace is scrapped, and causes the tremendous economic loss.
In addition, the metallic crucible of large-scale molten lead coreless-type induction furnace owing to reasons such as structure and processing, generally is not flat at the bottom of the crucible, but is the end socket shape of circular arc.Construction was all very difficult when the metallic crucible at the bottom of the circular arc end socket caused installation in body of heater, fixing and filling fire resisting material.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned prior art deficiency, but the stool of the plumbous coreless-type induction furnace of large-scale refining of a kind of Fast Installation, replacing metallic crucible has been proposed, save the installation, maintenance time and the maintenance cost of electric furnace greatly, improved service life and the economy and the reliability of electric furnace.
For achieving the above object, the technical solution used in the present invention is: the prefabricated refractory masses of furnace bottom that comprises grate and be arranged on the grate bottom, the prefabricated refractory masses of furnace bottom is provided with the stool of placing crucible, and is filled with refractory material around crucible.
Refractory material of the present utility model adopts soft alumina silicate fibre sticking.
Described stool comprises the base plate that is placed on the prefabricated refractory masses of furnace bottom, and the circular arc gusset and the reinforcement that match with the bottom surface circular arc of crucible are installed on base plate, is equipped with in the periphery of circular arc gusset to connect plumbous liquid plate.
Have three base plates on the described base plate and leak plumbous hole, offer three on the prefabricated refractory masses of furnace bottom equally and leak the plumbous hole prefabricated refractory material of corresponding furnace bottom and leak plumbous hole with base plate.
Described stool comprises the base plate that is placed on the prefabricated refractory masses of furnace bottom, and inner ring is installed on base plate, the outside that circular arc gusset that matches with the bottom surface circular arc of crucible and reinforcement are installed in this inner ring.
Offer several on the prefabricated refractory masses of described furnace bottom and leak plumbous hole.
The crucible of the utility model splendid attire molten metal directly is not positioned on the prefabricated refractory masses of furnace bottom, but the stool of a transition is set between crucible and the prefabricated refractory masses of furnace bottom, stool is positioned on the bottom refractory, and crucible places on the stool again.Refractory material around the crucible adopts soft alumina silicate fibre sticking, and is not only fire-resistant but also be incubated, and construction is convenient again.The setting of stool is changed the large-scale crucible of not being in the mood for responding to the plumbous electric furnace of refining fast and is achieved, and has solved the large-scale reliability engineering difficult problem of the plumbous electric furnace large-scale continuous production of refining in using of not being in the mood for responding to.
