Product overview

Magnesia-alumina-carbon brick serves transition-duty and mixed-pressure zones between classic magnesia-carbon severity and more balanced AMC service. It gives buyers a practical middle route for refined ladle zoning where real heat distribution and wear rhythm do not fit a two-material simplification.

Where it fits best

Some ladle positions carry more pressure than standard wall sections but less than the slag line. In those zones, MAC brick helps avoid under-specifying the material while also avoiding unnecessary over-costing.

Typical application zones

Transition zones between slag line and wall
Selected ladle wall and bottom positions
Refining-related working-lining areas that need both thermal balance and corrosion control

Buyer value

MAC gives the project team finer zoning control. That means more accurate material matching, less overdesign, and a better chance of extending vessel balance instead of shifting failure from one area to another.

Purchasing review points

Exact section map, transition-zone temperature pattern, slag behavior, cycling frequency, and whether the vessel is being designed around MC / AMC / MAC combined zoning.

Product overview

Al2O3-SiC-C brick is designed for hot-metal transport service such as torpedo ladles and iron ladles, where abrasion resistance, anti-stick behavior, thermal shock resistance, and transfer-cycle stability must be managed together. It is not simply a hot-face brick. It is a transport-duty route.

Why transport service needs a different logic

Transfer vessels are judged by charging, transport, discharge, stand-by, and reheating behavior. Buyers therefore look beyond corrosion resistance alone. They need a lining that can resist scouring, reduce adhesion, and remain stable through frequent thermal cycling.

Typical application zones

Torpedo ladles
Iron ladles
Hot-metal transfer sections and severe scouring zones

Route value for buyers

What the buyer is really buying is a steadier transfer cycle, not an isolated brick. Cleaner discharge, lower sticking risk, and more predictable maintenance intervals all feed directly into vessel availability and turnaround speed.

Purchasing review points

Vessel type, metal-contact condition, transfer frequency, anti-stick requirement, whether the lining is full or zoned, and what maintenance interval the buyer is targeting.

Product overview

Calcium-magnesia-carbon brick is used in selected refining-ladle and LF-VD / VOD related positions where thermal behavior, atmosphere, and process discipline differ from ordinary steelmaking service. It is a targeted route for buyers handling vacuum or refining-sensitive conditions.

Why it matters

Refining units are often mis-specified when ordinary steelmaking brick logic is carried over without adjustment. Calcium-magnesia-carbon brick gives buyers a route with better fit for vacuum stability, thermal-shock control, and process-related structural behavior in the vessel.

Typical application zones

Selected refining-ladle wall and bottom sections
LF-VD related wall and bottom routes
VOD or similar refining-sensitive positions

Buyer value

This route helps plant teams move away from generic lining logic and toward a section-specific refining package that better matches the operating environment.

Purchasing review points

Refining process type, vacuum or atmosphere condition, steel grade sensitivity, expected relining cycle, and how the route interfaces with nearby magnesia-carbon sections.
