Precautions for medium frequency furnace charge

Firstly,Ultra-high-strength lightweight ramming mass should be mechanically stirred when mixing, and forced concrete mixing should be used. Mixers, upper hoppers, weighing containers, etc. should be cleaned. The mixing time and the amount of liquid to be added shall be strictly in accordance with the instructions for the construction of the medium-frequency furnace neutral refractory material in the medium-frequency furnace.

Second, the mechanical equipment should be installed firmly, and the distance between the mechanical equipment and the pouring place should be as short as possible. Mechanical equipment should be used after inspection and adjustment.

Thirdly, Ultra-high-strength lightweight ramming mass must be measured according to the mixing ratio. The scales, measuring cups and measuring cylinders used must be verified by calculation. The various appliances used in the various construction stages of the ramming mass must be in good condition and kept clean.

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.
