Abstract
The utility model discloses a novel steelmaking arc furnace, which comprises a main platform, an arc-shaped frame and a tilting device, wherein the middle portion of a square beam body of the main platform is provided with an eccentric octagon beam structure, and the square beam body forms a gap. The novel steelmaking arc furnace is characterized in that one side of the gap of the square beam body of the main platform is further provided with a moving beam, one end of the moving beam is articulated with the main platform, and the other end is a free end. The utility model discloses a novel arc furnace steelmaking device which can use an EBT furnace body and also can use a steel spout furnace body, solves the problem that a steel spout type arc furnace and an eccentric furnace type arc furnace can not be unified, thereby leading two kinds of different furnace bodies to be capable of applied on the same tilting device, being capable of effectively producing quality steel and high additional value special steel, increasing the operation rate of equipment, leading adjustment of steel plant product structures and production arrangement to be more flexible, and reducing the initial investment of equipment.
Description
Technical field
The utility model relates to a kind of arc furnace equipment that is used to make steel, and belongs to the electrometallurgy field of mechanical technique.
Background technology
Since modern electric furnace arrangement for producing steel method invention, electric-arc furnace steelmaking has obtained extensive use.Arc furnace equipment can be divided into lander tapping electric arc furnaces and eccentric stove (EBT) tapping electric arc furnaces two big classes by furnace binding, in electric arc furnace smelting, because the appearance of eccentric stove (EBT) type of furnace, electric steelmaking process has produced radical change along with the new variation of steelmaking equipment, the EBT electric arc furnaces becomes thick furnace substantially, reduction in the steel-making and alloy fine setting are placed in the refining furnace to be handled, and makes the productivity ratio of electric arc furnaces obtain significantly improving.
The EBT electric arc furnaces becomes the main type of furnace of production high-quality steel, its advantage is that to make the old three phases work simplification of original steel-making be better simply scrap melting, the alloying of steel-making and reduction process are placed in the refining furnace and handle, thereby shortened smelting cycle, improved productivity ratio greatly, liberated the smelting work of electric arc furnaces, but the EBT electric arc furnaces also has its limitation, there are many special rolling-mill sections still to need the production of lander electric arc furnaces, in current intense market competition, along with development of science and technology, China's steel market needs a large amount of high-quality, high value-added product such as Aero-Space, nuclear power, industries such as military project, make lander formula electric furnace arrangement for producing steel equipment become the irreplaceable type of furnace, and tapping slot type electric arc furnaces is that with the main distinction of eccentric stove formula electric arc furnaces the structure of tiling arrangement is different.
Fig. 1 is the structural representation of traditional tapping slot type electric arc furnaces, and Fig. 2 is the structural representation of the main platform of traditional tapping slot type electric arc furnaces; Fig. 3 is the structural representation of traditional eccentric stove formula electric arc furnaces; Fig. 4 is the structural representation of the main platform of traditional eccentric stove formula electric arc furnaces.
As depicted in figs. 1 and 2: traditional tapping slot type electric arc furnaces comprises main platform 1, arc frame 1 and tiling arrangement 3, arc frame 2 is positioned at the bottom of main platform 1, itself and tiling arrangement 3 are hinged, wherein, the main platform 1 of traditional tapping slot type electric arc furnaces is a main spar body, and the middle part of main spar body then is an octagon girder construction; As shown in Figure 3 and Figure 4: the middle part of the main spar body of the main platform 1 of traditional eccentric stove formula electric arc furnaces then is the octagon girder construction of an off-centre, promptly wherein the position of a contact beam 4 is inner mobile to octagon, therefore, also can't realize tapping at present slot type electric arc furnaces and the unification between the two of eccentric stove formula electric arc furnaces.
The utility model content
In order to overcome the deficiencies in the prior art, the novel electric furnace arrangement for producing steel that the purpose of this utility model is to provide a kind of simple in structure, high efficiency, can effectively reduces production costs.
The utility model is achieved through the following technical solutions:
A kind of novel electric furnace arrangement for producing steel, comprise main platform, arc frame and tiling arrangement, wherein, the middle part of the main spar body of main platform is an eccentric octagon girder construction, and the main spar body forms a breach, it is characterized in that, side at the breach of the main spar body of main platform also is provided with a walking beam, one end and the main platform of walking beam are hinged, and promptly a side of an end of walking beam and above-mentioned breach is hinged, and the other end is a free end.
The beneficial effects of the utility model are: the utility model is a kind of electric-arc furnace steelmaking equipment that can use the EBT body of heater can use the lander body of heater again, it has solved the problem that tapping slot type electric arc furnaces and eccentric stove formula electric arc furnaces can't be unified, make two kinds of different bodies of heater all can be applied on the same tiling arrangement, steel of production high-quality expeditiously and high added value special steel, improved the operating rate of equipment, make steel mill product restructuring and scheduling of production more flexible, and reduced equipment and get one-time investment.
