Product details

1. Correct clamping position of electrode holder
The graphite electrode holder should not be clamped at the connection between the electrode and the electrode threaded hole.Sandwiched between white wires at each end of the electrode.At the same time, before clamping the electrode with the clamping device, the surface of the electrode and the clamping device is blown clean with compressed air to ensure the good conduction of current and heat flow between the electrode and the clamping device, to prevent damage to the clamping device due to arc, so as to prolong the service life of the cage limit.
2. What are the measures to reduce the oxidation consumption of eAF carbon electrode?
(1) Reduce the oxidation consumption around the electrode, strengthen the sealing of the furnace, reduce the air intrusion into the furnace, minimize the exposure time of the red hot electrode outside the furnace, and standardize the oxygen blowing operation.(2) For smelting furnace, if conditions permit, spray cooling technology can effectively reduce electrode side oxidation consumption.(3) The oxidation resistance of the electrode body can be improved by spraying antioxidant on the electrode surface in the steel plant or by using antioxidant impregnation technology before the electrode leaves the plant.(4) For the consumption of graphite electrodes, the use of hp graphite electrodes and uhp graphite electrodes in steelmaking can shorten the melting time of furnace charge, improve production efficiency, reduce electricity consumption and decrease the consumption of HP graphite electrode 3. What is the influence of electrode phase sequence on the use of electrode?
In the process of electric arc furnace (EAF) steelmaking, the jumping phenomenon of positive and negative phase sequence is very important.If the electrode phase sequence is clockwise, the carbon electrode will become loose after being energized for a period of time, which is easy to cause the electrode to become loose or the joint to break.The correct high quality graphite electrode phase sequence should be counterclockwise so that the electrodes are connected more and more tightly during use.
4. Why should the phase electrode be aligned with the top hole of the furnace cover when eAF steelmaking?
The electrode column should be aligned with the top hole of the furnace cover.The electrode column should avoid friction with the furnace cover.Otherwise, friction with the cover during lifting and lifting will cause the cover to squeeze and break the electrode.For AC furnaces, the three-phase electrode column should be kept parallel as far as possible.
