Development of High Performance Magnesia-chrome Brick for RH Furnace;

Study of Corrosion Mechanism of Magnesia Chrome Bricks Used in RH Furnace;

RH furnace multifunctional oxygen lance control system

Comparison of corrosion resistance of magnesia-zirconia brick and magnesia-chrome brick to RH furnace slag;

The closed loop soft water cooling system for the RH refining furnace is consist of surface evaporative air cooler,degassing tank,the device of stabilizing pressure and making up water and automatic medicine feeder,etc.

It is processed in slag splashing technique synchronously, thus, with the result of the furnace life of 11397 heats, the flow of bottom blowing on the latter heats of 0.

It is concluded that the proper and uniform lining erosion is obtained and base furnace life is increased largely after the application of single-layer long bricks,which provides steadily base practice for slag splashing lining protection.

The measures in technical management for the strengthening furnace type control ectare briefly introduced,the furnace life of 30t oxygen top blowing converter has been increased.
