Requirements for various parts of materials for aluminum melting and holding furnaces
1. Furnace safety insulation lining
Need to be able to effectively prevent the penetration of aluminum melting;
Under the pressure of aluminum melting, it does not deform and shrink.
A, ULTRA-CAST 300AR: high strength and better resistance to aluminum water penetration; recommended forsubhearth of large melting furnaces;
B, ALU-LITE 26AR: Lighter than ULTRA-CAST300AR, good thermal insulation performance. It is usually used in subhearth of small furnaces or holding furnace bottoms.
2.The hearth of the furnace and lower sidewall contact with the aluminum melting
Need very good resistance to aluminum melting penetration;
Good resistance to growth of corundum tumors;
Aluminum abrasion resistance
A, ALU-FLO 94AR high performance products, according to customer requirements;
B, ALU-FLO 86AR main recommended products;
C, ALU-FLO 60AR is used for small furnace lining or customer specific requirements.
3.Upper sidewall and roof of the reverb furnace
High temperature resistance and corrosion resistance to alkaline atmosphere in the temperature range of 980 to 1150 °C
Excellent thermal shock resistance and good wear resistance
A, ALU-FLO 80 is a high-purity alumina-based low-cement castable with excellent wear resistance and thermal shock resistance;
B, ALU-FLO 60/70 is a mullite-based low cement castable;
4.Lintel area, burner area
Excellent thermal shock resistanc;Wear resistance;Mechanical shock resistance
ALU-FLO 80 is a high-purity alumina-based low-cement castable with excellent wear resistance and thermal shock resistance;
5.Tap hole blocks
Excellent abrasion resistance performance;
Aluminum melting permeability resistant
A, ALU-FLO 94AR
B, ULTRA-CAST SIC SiC-based low-cement castables
