Abstract
The utility model belongs to an electric arc furnace, and particularly relates to an electron-beam technique (EBT) electric arc furnace for secondary slag-free tapping. The EBT electric arc furnace of the secondary slag-free tapping comprises a furnace body, an EBT tapping port and a fixed plate, wherein the EBT tapping port is level and arranged on the upper part of the furnace body, and the fixed plate is installed on the lower part of the furnace body. The fixed plate is connected onto the furnace body through a pin shaft. The furnace body is also provided with a fixed stop block. The horizontal slag-free tapping port with secondary tapping capacity is developed on the basis of the tapping of the traditional electric furnace EBT. By adopting the unique design, the secondary or multi-time slag-free tapping of the EBT electric arc furnace can be realized. In addition, the EBT electric arc furnace is simple in structure and convenient to operate and use; and the EBT electric arc furnace is low in cost and suitable for being popularized to use in relevant technical fields.
Description
Technical field
The utility model belongs to a kind of electric arc furnace, specifically a kind of EBT electric arc furnace that can the secondary slag free tapping.
Background technology
Along with the development of smelting iron and steel technology, the EBT electric arc furnace is used widely.According to different processing requirements, conventional EBT electric arc furnace can only be realized disposable slag free tapping, that is: in a single day the EBT mechanism that is positioned at furnace bottom opens, and requires the necessary disposable outflow of molten steel in the stove.Yet often require twice tapping of one heat steel moisture in the reality, one heat steel water will so, just require electric arc furnace to have secondary and go out steel functional with two ladle splendid attires in other words, and is at present domestic temporary without this type of technology.
The utility model content
The purpose of this utility model is in order to solve deficiency of the prior art, provide a kind of can secondary or the EBT electric arc furnace of slag free tapping repeatedly.
The EBT electric arc furnace of secondary slag free tapping comprises body of heater, EBT tap hole, retaining plate, and wherein, the EBT tap hole is level, and is arranged on the top of body of heater, and retaining plate is installed in the bottom of body of heater.
Described retaining plate is connected on the body of heater by bearing pin.
Also be provided with fixed stop on the body of heater.
Develop the horizontal slag free tapping mouth with secondary tapping ability on the tapping basis of traditional electric furnace EBT, unique design of the present utility model can realize the secondary of EBT electric arc furnace or slag free tapping repeatedly.In addition, the utility model is simple in structure, and handled easily uses; Cost of the present utility model is not high, is adapted at promoting the use of in the correlative technology field.
Description of drawings
Fig. 1 is structural representation of the present utility model
Among the figure: 1, body of heater; 2, EBT tap hole; 3, retaining plate; 4, bearing pin; 5, fixed stop.
Embodiment
For making the technical solution of the utility model and characteristics clearer, below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail.At this, following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the EBT electric arc furnace of secondary slag free tapping comprises body of heater 1, EBT tap hole 2, retaining plate 3, and wherein, EBT tap hole 2 is levels, and is arranged on the top of body of heater 1, and retaining plate 3 is installed in the bottom of body of heater 1.
Described retaining plate 3 is connected on the body of heater 1 by bearing pin 4.
Also be provided with fixed stop 5 on the body of heater 1.
The concrete secondary of the utility model is tapped as follows:
Once tapping
When body of heater 1 interior molten steel reaches the tapping condition, open first EBT tap hole 2, opener requires to calculate the angle that body of heater 1 tiling arrangement needs tilt according to tap, and ladle winched to connects package location, makes body of heater 1 tapping of tilting.After having connect molten steel, the angle of body of heater 1 is back to the smelting state, closes horizontal tap hole opener, hangs away ladle and casts.
The secondary tapping
In secondary when tapping,, steel tapping vehicle moves to and connects package location, opens furnace bottom EBT opener, and strengthens gradually body of heater 1 angle of inclination to body of heater 1 interior molten steel and flow in the ladle on the steel tapping vehicle.After having connect molten steel, the angle of body of heater 1 is back to the smelting state.Leave steel tapping vehicle, hang away ladle and cast.
Obviously, above-described embodiment of the present utility model only is for the utility model example clearly is described, and is not to be restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give all embodiments exhaustive.Everyly belong to the row that apparent variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
Claims (3)
1. the EBT electric arc furnace of secondary slag free tapping comprises body of heater, EBT tap hole, retaining plate, it is characterized in that the EBT tap hole is level, and is arranged on the top of body of heater, and retaining plate is installed in the bottom of body of heater.
2. the EBT electric arc furnace of secondary slag free tapping according to claim 1 is characterized in that described retaining plate is connected on the body of heater by bearing pin.
