Maintenance of ramming mass for EAF bottom

1.The slag resistance of EAF bottom ramming mass is not very good, ensure slag line above the slope when charging scrap.

2.If there is pit on the bottom, lean the furnace backwards, use compressed air to blow the remaining steel and slag onto the slope, after furnace cooled down, fill the pot with ramming mass and make it flat, then make it compact with pneumatic rammer. If there is pit on the slope, repair it with the same method.

3.If cold maintenance is not possible, mix ramming mass with water and then do a hot repair, press until it’s compact.

4.Daily maintain the water cooling components, if there is a water leakage, handle it in time to avoid the furnace to be affected with damp, which could cause serious accidents.
