Abstract
The utility model discloses an electrode clamp of an electric arc furnace, which comprises an electrode clamp head and a connecting seat used for fixing the electrode clamp head, wherein the electrode clamp head comprises an outer wall and an inner wall which are parallel to the axis of a clamped electrode, and a water channel is formed between the outer wall and the inner wall; a graphite gasket is arranged between the electrode clamp head and an electrode contact part; the inner wall is formed by connecting a stainless steel plate and a common steel plate; and the graphite gasket is attached on the common steel plate. The electrode clamp of the electric arc furnace has the advantages of good conducting effect and long service life.
Description
Technical field
The utility model relates to a kind of electrode jaw, refers to a kind of electrode jaw that is used for arc furnace particularly.
Background technology
Arc furnace is a kind of widely used industrial furnace, is exactly wherein a kind of as the ladle refining furnace of one of capital equipment in the steel industry.The electrode jaw of arc furnace is made by stainless steel usually, thus the situation that can block eddy current effectively, cut down the consumption of energy and generate heat.But,,, cause electrode jaw to be leaked and lost efficacy by arc through in the heavy current impact bottom electrode and the usually starting the arc of electrode jaw contact site because the electric conductivity of stainless steel own is relatively poor.Existing electrode jaw is very short useful life, only is about one month.Need one to two hours and change electrode jaw, have a strong impact on production and increased the weight of working strength of workers.Therefore, need a kind of improved arc furnace electrode clamper badly to overcome aforementioned disadvantages.
Summary of the invention
The purpose of this utility model is exactly to provide that a kind of conductive effect is good, the arc furnace electrode clamper of long service life, uses this kind electrode jaw to enhance productivity, and reduces production costs.
For achieving the above object, the designed arc furnace electrode clamper of the utility model comprises terminal clamp and the Connection Block that is used for fixing described terminal clamp.Described terminal clamp comprises outer wall and the inwall with the parallel axes of the electrode that is held, form aquaporin between described outer wall and the described inwall, described terminal clamp and described electrode contact portion are provided with Graphite pad, described inwall is formed by connecting by corrosion resistant plate and general steel plate, and described Graphite pad is attached on the described general steel plate.
Advantage of the present utility model is: the part that designed arc furnace electrode clamper contacts with electrode adopts Graphite pad, and Graphite pad is attached on the general steel plate, have good electrical conductivity, thereby eliminate the phenomenon of the starting the arc, and then prolong the useful life of arc furnace electrode clamper.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the utility model arc furnace electrode clamper;
Fig. 2 is the A-A line cutaway view of arc furnace electrode clamper shown in Figure 1.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As depicted in figs. 1 and 2, arc furnace electrode clamper of the present utility model comprises terminal clamp 20 and the Connection Block 10 that is connected with described terminal clamp 20, and this Connection Block 10 is connected described terminal clamp 20 on the clamper body (figure does not show).Described terminal clamp 20 comprises outer wall 21 and the inwall 23 with the parallel axes of the electrode that is held (figure does not show), form aquaporin 22 between described outer wall 21 and the described inwall 23, described terminal clamp 20 is provided with Graphite pad 30 with described electrode contact portion, described inwall 23 is formed by connecting by corrosion resistant plate and general steel plate, the most handy stainless steel welding.Described Graphite pad 30 is attached on the described general steel plate.Aforementioned general steel plate is preferably the A3 steel.As the preferred embodiment of the utility model arc furnace electrode clamper, described terminal clamp 20 is cylindrical, the parallel axes of its axes O and the electrode that is held.That is to say that described inwall 23 and outer wall 21 are cylindrical so, the position of the pairing central angle a=90 of its general steel plate part ° and described general steel plate is relative with described Connection Block 10.
In the present embodiment, be provided with press strip 24 around the described Graphite pad 30, described Graphite pad 30 is stuck on the described inwall 23 by described press strip 24.Particularly, described press strip is common A3 steel bar, is welded on the described inwall 23.
