IBAR Refractories: MgO-C, Alumina and Fireclay Bricks, Castables, Ramming Mixes

Selection and quotation of IBAR refractories from Brazil: basic, alumina, silica-alumina and insulating bricks, castables, ramming mixes, plastics, mortars and anchors.

Basic Refractories: MgO-C, Magnesia-Chromite and Magnesia-Spinel Bricks

IBAR MgO-C bricks combine high-purity magnesium oxide and graphite bonded with phenolic resins, plus additives against oxidation. They line steel ladles, electric arc furnaces and BOF converters. Magnesia-chromite bricks with 55% to 81% MgO serve cement kilns, lead and copper plants.

MgO-C bricks bonded with phenolic resins
Magnesia-chromite: 55–81% MgO, fired up to 1550 °C
Magnesia-based bricks: 81–98% MgO
Magnesia-spinel bricks for cement rotary kilns

Alumina-Based Bricks: Fired and Resin-Bonded

Fired IBAR alumina-based bricks contain 46% to 99% alumina and use chamottes, fused alumina and high-purity sintered alumina. Resin-bonded Al2O3-SiC-C bricks are cured at around 200 °C for torpedo cars and hot metal ladles, while Al2O3-MgO-C bricks line steel ladles.

Silica-Alumina and Silica-Based Bricks

Dense IBAR silica-alumina bricks contain 22% to 46% alumina and use clay-based chamottes low in iron oxide and alkalis. They serve cement and lime, steel, aluminum and non-ferrous plants. Silica-based bricks with 65% to 97% SiO2 line coke ovens and glass furnaces.

Silica-alumina bricks: 22–46% alumina
Chamottes low in iron oxide and alkalis
Silica-based bricks: 65–97% SiO2
Deformation resistance above 600 °C

Insulating Bricks

IBAR silica-alumina insulating bricks are low-density products of 0.50 to 1.10 g/cm³, made by extrusion and pressing. They are used at temperatures up to 1400 °C. Low thermal conductivity and density make them the insulating layer of high-temperature furnaces.

Refractory Castables: Conventional, Low-Cement and No-Cement

Conventional IBAR castables contain over 2.5% calcium oxide from calcium aluminate cement, low-cement grades 1.0% to 2.5% and ultra-low-cement grades 0.2% to 1.0%. No-cement grades harden by chemical reactions. They are poured, vibrated, shotcreted or pumped.

Conventional grades: CaO above 2.5%
Low-cement grades: 1.0–2.5% CaO
Ultra-low-cement grades: 0.2–1.0% CaO
Shotcreting, pumping and dry gunning

Ramming Mixes: Dry, Wet and Dry Granular

IBAR dry ramming mixes are bi-component: a dry aggregate part and separate additives, typically phosphate-bonded. Wet ramming mixes come packaged at working consistency, including alumina-silicon carbide-carbon grades. Dry granular mixes are placed by dry vibration or rammed with special forks.

Plastics, Mortars and Coatings

IBAR plastics blend refractory aggregates of different particle sizes and come at working consistency in silica-alumina, alumina, alumina-chrome and silica-based grades. Mortars are wet or dry, air-setting or ceramic-setting. Coatings go on working linings by hand or by spraying.

Metal Anchoring Devices for Linings

The METALLICS division of IBAR machines metal anchoring devices that keep refractory masonry stable, plus composite metal and ceramic anchoring systems. Materials include carbon steel SAE 1010/1020, stainless steels AISI 304, 304S, 310 and 310S, Inconel, cast iron and cast steel.

Steel Ladle: Grades by Zone

IBAR lists steel ladle refractories by zone. The metal line takes IBAR MGC PA 6100 DS, PROMAG IBAR Q 84 LD-B, ALUMIBAR 70 PAC, SUPERIBAR SA 45, CASTIMAG IBAR 92 DC and BIOPLATE 1300. The slag line takes PROMAG IBAR Q 84 LD-B, IBARMAG 93, SUPERIBAR SA 45 and BIOPLATE 1300.

The rim takes SUPERCASTIBAR DD 70 FI-2%, and the slide gate valve and purging plug seats take ULTRACASTIBAR 92 SP E.

Electric Arc Furnace: Hearth, Walls, EBT

For the electric arc furnace IBAR lists grades by zone. The hearth takes RAMMAG DL S, the banks RAMMAG DL RO and the permanent lining IBARMAG 93.

The walls use the IBAR MGC FEA series: 10100 A, 10100 B, 10100 BD, 10100 BD OX, 10100 D, 1050 B W and 1360 W. The EBT taphole takes IBARMAG 13 CG EF, CASTMAG IBAR 90 DC and IBAR MGC FEA 8100 D.

BOF Converter: Bottom, Barrel, Taphole

For the BOF converter IBAR lists grades by zone. The bottom takes IBARMAG 5 CS, CASTIMAG 90 DC, IBARMAG 93 and CASTIBAR N. The first barrel ring takes IBARMGC LD 100 with IBARMAG 93, the second IBARMGC LD 70 with IBARMAG 93.

The taphole uses IBARMGC LD 100 and CASTIMAGIBAR 90 DC, the mouth CASTIMAGIBAR 90 DC. MgO-C bricks offer resistance to thermal shock and corrosion at high temperatures.

Cement Rotary Kiln by Zone

In the cement rotary kiln IBAR assigns grades as follows: nose ring SUPERCASTIBAR DD 85, lower transition zone MAGNIBAR 89, burning zones MAGNIBAR 86 and MAGNIBAR 89, upper transition zone ALUMIBAR 70, calcining zone SUPERIBAR SA, inlet cone SUPERCASTIBAR DD 65.
