Lining Concept

Refractory Protection for Steel Ladle Service

A steel ladle lining must withstand molten-steel contact, aggressive slag, thermal cycling, impact during filling and mechanical wear throughout repeated heats.

Magnesia-carbon bricks are particularly suitable for slag-line applications. The supplied information lists MgO-C grades with 97% MgO and fixed-carbon levels from approximately 5% to 14%. For the bottom impact area, alumina-magnesia-carbon bricks are recommended in the source material.

Main Advantages

Advantages of the Ladle Refractory System

Cost-Effective Selection Zoned product selection can balance lining performance and refractory consumption.

Flexible Magnesia Source The product concept allows selection between sintered and fused magnesia formulations where technically suitable.

Resin-Bonded Structure Resin-bonded MgO-C products are used for selected ladle working-lining applications.

Oxidation Resistance Formulations are selected to support carbon retention and lining performance in service.

Lining Zones

Main Areas of the Steel Ladle Lining

Each ladle area experiences a different combination of slag attack, metal contact, impact, heat loss and structural loading.

Closing Ring Upper structural refractory zone around the ladle rim.

Freeboard Upper lining above the normal steel and slag level.

Slag Line Severe chemical-wear zone commonly lined with magnesia-carbon bricks.

Sidewall Main vessel wall exposed to molten steel, heat and repeated operating cycles.

Insulating Layer Layer intended to reduce heat loss through the ladle shell.

Ramming Mix Monolithic material used in selected joints, backing and bottom zones.

Bottom Lower working-lining area exposed to molten steel and structural load.

Impact Area High-wear zone receiving the initial impact of incoming molten steel.

Product Range

Refractory Products for Ladle Working & Safety Linings

The supplied pages identify five principal product groups for working linings, impact zones, safety linings and monolithic installation.

Magnesia-Carbon Refractories

MgO-C bricks for ladle working linings, especially slag-line and other basic high-wear zones.

Alumina-Magnesia-Carbon Bricks

AMC bricks for the metal zone, impact pad and bottom areas requiring resistance to impact and thermal cycling.

High-Alumina & Chrome-Magnesia Safety Bricks

Refractory bricks for permanent and safety lining behind the hot-face working lining.

High-Alumina Low-Cement Castables

Monolithic refractory castables for selected ladle installation, repair and transition areas.

Magnesia-Dolomite Refractories

Basic working-lining products based on magnesia and dolomite for compatible ladle operating conditions.

Magnesia-carbon and alumina-magnesia-carbon refractory bricks for steel ladles

Brick Grade Range

MgO-C and MgO-Doloma-Carbon Ladle Bricks

The listed magnesia-carbon grades contain 97% MgO with fixed-carbon levels from 5% to 14%. The supplied table also includes two magnesia-doloma-carbon grades containing 50% MgO and 48% CaO.

The final grade should be selected according to the slag line, sidewall, metal zone, bottom, impact exposure and the customer’s approved ladle-lining design.

5–8% Carbon Lower-carbon MgO-C grades listed with 97% MgO.

10–14% Carbon Higher-carbon MgO-C grades for technical comparison.

MgO-Doloma-C Grades containing 50% MgO and 48% CaO.

Technical note: The table applies to the listed MgO-C and MgO-doloma-carbon grades. It should not be assumed that the same values apply to the alumina-magnesia-carbon bricks, safety bricks or low-cement castables. Final selection must be based on approved technical data sheets, ladle drawings, slag chemistry, operating temperature and wear history.
