How to avoid the electrode from breakage and tripping in the process of steelmaking?

Taking the following measures can effectively avoid electrode from breakage and tripping in steelmaking process: 

1) the phase sequence is correct, that is anticlockwise. 

2) steel scrap uniform distributed in the furnace and try to put large pieces of steel scrap at the bottom of the furnace. 

3) avoid non-conductive material in scrap. 

4) electrode column and the top hole alignment, and parallel to the electrode column. The top hole wall should clean up frequently to avoid accumulation of residual steel slag to force electrode to break. 

5) to keep the electric furnace tilting system in good condition, and keep the electric furnace tilting steady. 

6) the electrode holder should not be placed in the joint and sockets. 

7)choose to use high strength, high machining accuracy and high quality nipples. 

8)torque should be appropriate for electrode connection. 

9) to prevent the mechanical damage of electrode socket thread and nipple thread in and before the process of jointing. 

10) steel slag or foreign material shall prevent from embedding the socket and nipple which may affect screwing.
