Selection and quotation of Allied Mineral Products refractories: DRI-VIBE dry vibratables for induction furnaces, castables, precast shapes, gunning mixes and taphole clay.

DRI-VIBE and MINRO-SIL Dry Vibratables for Induction Furnaces

DRI-VIBE dry vibratables line induction furnaces melting zinc, aluminum, copper, iron and high-temperature steels. No cure or dry-out is needed: the mix is completely dry with a heat-set bond. Grades: alumina-magnesia for steel, MINRO-SIL silica for iron, non-wetting alumina for aluminum.

Steel: DRI-VIBE 682A, limit 1815 °C
Iron: MINRO-SIL 2001, SiO₂ 99.2%
Aluminum: DRI-VIBE 520A, 90% Al₂O₃
No dry-out: heat-set bond

Mixes for Channel Furnace Inductors

The DRI-VIBE line also lines channel holding and pouring furnaces and the channel inductors that heat them. Inductor grades include the spinel forming alumina DRI-VIBE 306A and magnesia DRI-VIBE 696M. Iron channel units take alumina MINRO-AL RAM A26 and DRI-ROK 2029A with SiC.

Refractory Castables for Foundries

Allied has made refractories for the foundry industry since 1961. The castable range covers conventional and low-cement, no-cement and colloidal silica bonded grades. Ultra-low cement V-CAST and no-cement TEK-CAST serve metal containment, METAL KAST and KAST TECH cover high-temperature duty.

METAL KAST 90: limit 1870 °C
KAST TECH 34: Al₂O₃ 95.8%
V-CAST 426A: limit 1705 °C
High fiber grades ARMORMAX, METAL-ROK

Aluminum Refractories: WAM AL, MATRIFLO, QUICK-FIRE

The WAM AL family serves aluminum melting and holding furnaces and uses high-purity synthetic materials with low silica content. MATRIFLO grades are high alumina, low cement castables for aggressive aluminum alloys. QUICK-FIRE mixes use a two-component liquid phosphate bonding system.

MATRIFLO 85ACX: limit 1540 °C
MATRIFLO: resistant to salt flux
QUICK-FIRE 88 veneer: 2+ years without wall repair
Previously a quarterly repair schedule

Precast Refractory Shapes

Allied makes custom-engineered precast, pre-fired refractory shapes. Its precast shape centers draw on over 1,000 refractory formulations and over 50 years of shape production. Foundry shapes include crucibles, launders and spouts; heat treat shapes include hearths, car tops and burner blocks.

METAL-ROK for aluminum furnace wear areas
Hearths, burner blocks, pier blocks

Plastics, Patching and Gunning Mixes

Allied plastics and patching materials extend refractory campaign life and bond to the existing refractory. FAST-DRY and REZIST ABRADE are low-cement gunning refractories heated up with no holds. ACTCHEM resists abrasion and is used in fluidized catalytic cracking units.

RAM MAX 85 P: 85% alumina, phosphate bonded
FAST-DRY: heat-up 120 °C per hour
REZIST ABRADE: heat-up 60 °C per hour
ACTCHEM 85: up to 3 cm³ loss at 815 °C

RSR Taphole Clays for Blast and Alloy Furnaces

Allied taphole clays span from siliceous grades for the alloy industry to high-alumina grades for high-production, multiple-taphole blast furnaces. Anhydrous RSR clays are chosen by hot metal output per day and drilling practice. A restoration clay fills cracks in the taphole clay column.

RSR 963 T: over 10,000 t of hot metal per day
RSR 902: two tapholes, up to 8000 t per day
RSR 1133: no coal tar products
RSR 101: 4000–6000 t, conventional drilling

Lightweight Mixes, Insulating Castables and Mortars

DRI-LITE and LADLE-VIBE lightweight dry vibratables give a joint-free backup lining behind bricks, crucibles or shapes. BETAMAX and INSULMIX insulating castables and gunning mixes offer fast dry-out and a wide range of installed densities. Mortars come in troweling or dipping consistency.

DRI-LITE 65A-L: 0.96 g/cm³, limit 1400 °C
BETAMAX 23 LT G: gunned, 1.23 g/cm³
ARMORSET 90 P mortar: limit 1815 °C
Joint-free backup lining

Coreless Induction Furnace: Products by Zone

Allied supplies refractories for all parts of a coreless induction furnace. The working lining for steel is rammed with alumina-magnesia DRI-VIBE grades; DRI-VIBE 975A covers low to high temperature steels and irons in all furnace sizes.

For gray and ductile iron, copper and brass, the high purity silica MINRO-SIL 2001 LD offers thermal shock resistance for single shift operations. The top cap takes DRI-VIBE 493A with magnesia addition, the spout takes RAM MAX 85 P plastic.

Vaporshield mica forms the slip plane, the coil is grouted with self leveling COIL-CAST 97A, and the cover is cast from INSULMIX 33100 insulating castable.

Channel Furnace: Inductor and Working Lining

Allied refractories for channel furnaces cover melting, holding and pouring of iron, copper, aluminum and zinc alloys.

The inductor is rammed with spinel forming dry vibratables: alumina DRI-VIBE 306A or magnesia DRI-VIBE 696M. The working lining of iron furnaces uses large grain DRI-ROK 2029A with SiC or low porosity TEK-CAST 712A with 12% SiC.

Receivers and pour spouts are cast from ultra low cement CAST MAX MB HP based on mullite and bauxite, and local wear is repaired with TEK-GUN 31A hot gunning mix.

Heat Treat and Forge Furnace Hearths

DRI-VIBE products for heat treating and forging are heat-set refractories for lining or restoring the furnace hearth surface. Dense DRI-VIBE 434A (54.9% Al₂O₃) and DRI-VIBE 88A (85.9% Al₂O₃) serve the hearth, lightweight DRI-LITE grades serve subhearths.

Steel fiber reinforced ARMORMAX withstands repeated thermal cycling, mechanical impact and abrasion and suits continuous exposure up to 1200 °C. Hearths, car tops, walls, burner blocks and pier blocks are also made as precast shapes.

Taphole Clay by Furnace Output

RSR taphole clays are selected by hot metal output, the number of tapholes and drilling practice. RSR 101 is an anhydrous clay for medium-size furnaces producing 4000–6000 t of hot metal per day with conventional drilling, and RSR 1170R-W is designed for gap times of 25–30 minutes.

RSR 902 extrudes easily and drills with low resistance on two-taphole furnaces producing up to 8000 t per day, while RSR 963 T serves furnaces producing over 10,000 t per day. A restoration clay fills cracks in the taphole clay column.
