KALTEK ladle liners are an insulating ladle refractory system for use in iron and steel casting processes. They are available in two general configurations: board systems that can be easily assembled to form a multi-piece working lining and shank systems that comprise a one-piece monolithic ladle liner.

KALTEK liners offer superb thermal insulation compared to conventional refractory systems, with some systems offering increased suitability to a variety of application and thermal conditions.

The use of insulating liners allow foundries to adopt a lower tapping or holding temperature practice and/or to reduce the variation in metal pouring temperatures. This will result in a reduction in alloy consumption (increased alloy recovery), lower energy consumption, a reduction in furnace refractory consumption, and fewer slag inclusions and temperature-related casting defects. A reduction in ladle maintenance and assembly direct labor costs will also be realized through the use of KALTEK Ladle Linings. Most KALTEK linings can be installed quickly, with minimum training, and without the need for capital investment. The linings can be used for a single heat in batch processes or reused after repeated thermal cycles when proper care is taken to control the lining cooling rate. The lining can be deskulled after service with minimal effort.

Foseco’s KALTEK Ladle Lining products provide:

• Reduced defects, because foundries using lower tapping and holding temperatures and more consistent pouring temperatures will experience fewer temperature related defects. Further, use of KALTEK liners as part of a clean metal practice will lead to fewer slag inclusions.
• Increased productivity, since KALTEK systems are simpler and faster to install than other liner systems and require less maintenance. KALTEK systems are virtually always more economical than alternative practices when production rate and results are taken into account.
• Improved quality, because KALTEK systems are produced in a carefully controlled process, their use can help reduce the variability a foundry’s melt process. A more robust process at lower, more consistent temperatures, is an important tool in the effort to produce superior metallurgical and physical properties in the finished product.
