Lining engineering
Concepts for BOF converters, EAFs, ladles, tundishes and vacuum vessels, including zonal material selection.
REFRACTORY ENGINEERING FOR STEELMAKING
Built around the heat
Engineered around your process
Refractory solutions for primary steelmaking, secondary metallurgy and continuous casting — designed as a complete lining concept or supplied precisely to your technical specification.

01 / 05FROM TECHNICAL BRIEF TO LINING PERFORMANCE
Every furnace tells us what it needs
We combine refractory products with practical metallurgical engineering. Whether you start with operating data or a finished technical specification, the answer is matched to the temperature, slag, steel grade and maintenance window of your operation.

The grade follows the application
Material chemistry, density, porosity, strength and treatment conditions are defined by the lining zone and your operating regime — not by a generic product name.
For brick linings, performance is assessed by campaign life in heats or minutes and by refractory consumption per tonne of steel. Our objective is a stable lining campaign with low specific refractory consumption.

THE WORKING METHOD
A clear path from problem to lining
- 01
Understand the duty
Review vessel design, process route, service life target and repair strategy.
- 02
Select the system
Develop the zonal concept or verify the material package against your specification.
- 03
Deliver with discipline
Coordinate documentation, packaging and supply around the planned shutdown window.
- 04
Support performance
Assist the installation and use feedback from operation to refine the next campaign.
STANDARDS & DOCUMENTATION
Technical data that speaks the same language
Where required by the project specification, material grades and technical documentation are aligned with relevant EN, DIN EN, ASTM and GB/T standards. Final acceptance criteria are agreed for the specific application.
