Rath Incorporated has the refractory lining solution for forging reheat furnace users that want to reduce maintenance downtime and costs, while improving energy efficiency. Widely proven in Europe, this lining system is now available in North America.

Roof Design

ALTRA® COMBI modules are rated for applications to 1600°C. The hot face fiber, ALTRA® 72, is far superior in resistance than 2300 or 2600 grade ceramic fiber to shrinkage caused by temperature and chemical attack. ALTRA® COMBI modules are also immune to thermal shock, a major cause of failure for castable or all-brick linings in reheat furnaces.

Burner Blocks

ALTRA® Burner Blocks are rated for applications to 1650°C. ALTRA® Burner Blocks are immune to thermal shock, eliminating the cracking, spalling and disintegration common with castable or vacuum formed burner blocks.

Car Refractory

Large blocks directly cast on the cars improve the flatness of the car and reduce the number of joints. Joints in reheat cars are well known as a source of problems due to the accumulation of slag from the steel castings. Carath castables are engineered for excellent thermal shock resistance and load bearing capabilities, making them ideally suited for this difficult application.

Sidewalls

Low mass Porrath Insulating brick are used in areas with potential for damage from contact with the casting. ALTRA® COMBI Modules are used in areas with no chance of contact. The two products give the best possible combination of durability, low maintenance and low heat loss.
