Argon oxygen furnace is fireproof of li of line mar and of area differentiate

Design of the choice of fireproof material, body of heater and build by laying bricks or stones build each aspects such as the technology is to help us optimize the important step of lining of argon oxygen furnace.

Argon oxygen furnace

The experience that inchoate applying already made clear: The mechanical wear that every area gets mixes lining of argon oxygen furnace eroding is each are not identical. In general, its are fireproof what liner gets is main wear away and erode as follows:

1, because decarbonization is mixed,reduce what slaggy alkalinity place gets to erode greatly;

2, of two kinds of backset that get in blast tuyere area erode;

3, the thermal shock that arises in change of the temperature in whole smelt process;

4, because be the same as strong reducer and incendiary agent (chemistry of Si, Al) happening reacts place generation is eroded.

For example, blast tuyere brick and fender should suffer the thermal shock that cold air produces, produce unripe wear awaying by eddy current, of the limiting temperature effect that by oxidation reaction produces and reaction child erode.

Additional, area of liner tall corrode is the division of broken bits line of argon oxygen furnace, especially trunnion position, this area is in from beginning to end with slaggy contact condition. If slaggy alkalinity is inferior, erode in eddy current while, also happen to erode what what cause to mar by chemistry.

Furnace of balance argon oxygen is different of the fireproof liner of place mar mode and reducing a method that fireproof cost of raw materials uses ton of steel is fireproof to argon oxygen furnace liner undertakes area carefully differentiate, execute line of integrated build by laying bricks or stones, in order to achieve balanced mar, raise the goal of lining service life.

The quality of the composition that delimits divisional region needs a basis to mar mode, brick, brick and ply (the composition that should consider a brick at the same time and quality) . The magnesian chromium that serves as different quality is qualitative fireproof data is comprehensive a typical case of furnace of build by laying bricks or stones, what can use magnesian chromic qualitative fireproof liner as furnace of design argon oxygen is referenced.
