Description

Arc furnace electrode regeneration device

Technical field:

The utility model relates to a kind of electrode assembly, relates in particular to a kind of arc furnace electrode regeneration device.

Background technology:

Electric-arc furnace steelmaking is to utilize the high-temperature electric arc that produces between electrode and the metal charge to come the deposite metal, the electrode material conductance is high and high temperature resistant, when the electrode burning shortens in steelmaking process, stretch less than in the body of heater, for guaranteeing the requirement of steel-making quality, the electrode that must will shorten is more changed, because of the electrode expense higher, increase operation cost of enterprises as frequent replacing, the electrode that burning shortens can not re-use, and causes the wasting of resources.

Summary of the invention:

The utility model provides a kind of arc furnace electrode regeneration device at the deficiencies in the prior art.

For realizing the above object, the technical solution adopted in the utility model is:

Arc furnace electrode regeneration device is made up of fixed electrode support, rise fall of electrodes controller, electrode supporting cross bar, electrode jaw, new electrode, electrode nipple, old electrode, electrode sealing ring; The rise fall of electrodes controller is housed on the fixed electrode support, electrode jaw links to each other with the rise fall of electrodes controller by the electrode supporting cross bar, new electrode and old electrode two ends are provided with screwed hole, and inside is connected new electrode by electrode nipple with old electrode, and the electrode sealing ring is equipped with in old electrode lower end.

Described arc furnace electrode is to adopt conductance height and resistant to elevated temperatures graphite to make, and is shaped as pole.

The utility model adopts new electrode and old electrode two ends to be provided with screwed hole, inside is connected new electrode by electrode nipple with old electrode, electrode jaw is clamped new electrode, utilize the rise fall of electrodes controller to regulate old electrode and new distance between electrodes, realize that old electrode nipple connects the specification requirement of new electrode, make old electrode be deep into fully burning in the body of heater, economize on resources, reduce cost.

Description of drawings:

Fig. 1 is the utility model structure chart;

Embodiment:

As shown in Figure 1, arc furnace electrode regeneration device is made up of fixed electrode support 1, rise fall of electrodes controller 2, electrode supporting cross bar 3, electrode jaw 4, new electrode 5, electrode nipple 6, old electrode 7, electrode sealing ring 8; Rise fall of electrodes controller 2 is housed on the fixed electrode support 1, when old electrode 8 burnings shorten, unclamp electrode jaw 4, old electrode 7 slips into body of heater along electrode sealing ring 8, the electrode nipple 6 that utilizes graphite to make is connected on the old electrode 7, after new electrode 5 is put into electrode jaw 4 and stepped up, regulates old electrodes 7 and the new distance between the electrode 5 by rise fall of electrodes controller 2, electrode nipple 6 connects new electrode 5, and old electrode 7 can pass electrode sealing ring 8 and goed deep into body of heater and continue to use this moment.

In order to guarantee that old electrode 7 is connected the requirement of regeneration with new electrode 5, old electrode 7 afterwards must be more than or equal to the height of electrode nipple 6 with the screwed hole degree of depth of new electrode 5, and old electrode 8 equates with the cross section same diameter of new electrode 6.

The utlity model has easy to operate, overall structure simple, economize on resources, reduce cost, prevent to pollute advantage such as bad border, have great promotional value.
