Troughs and Launders

Rex Materials' High Performance Metal Delivery System™ utilizing Pyroform™ or Pyrolite® refractory technologies allow producers to eliminate launder pre-heating, avoid the need to “super-heat” the metal in in-line equipment and, most importantly, reduce holding furnace temperatures by as much as 122°F/50°C (or more in very long launders and/or low flow applications). Rex Materials' Metal Delivery Systems are extremely abrasion resistant and are good where thermal losses are less critical. Due to its superior thermal shock resistance and high modulus of rupture, , far outlasts standard fused silica materials in launder applications.

Superior Thermal Performance...
Exceptional Value

The top metal casting companies in the world demand the best. That's why they choose Pyroform HP™, the leading refractory, for use in their launders and other metal delivery systems.

Because of its thermal insulating properties and durability, Pyroform HP is the only refractory material specified by Wagstaff for their billet casting systems and LaundAir low-warpage ingot casting launders. Rex Materials' High Performance Metal Delivery System™ utilizing Pyroform HP or Pyrolite refractory technologies allow producers to eliminate launder pre-heating, avoid the need to "super-heat" the metal in in-line equipment and, most importantly, reduce holding furnace temperatures by as much as 50°C.

Bottom line. Choose Pyroform HP for superior thermal performance and exceptional value.

Superior Wear Performance...
Exceptional Properties

When your process calls for superior wear and durability, preformed fused silica shapes are the ones to choose. represents a family of high purity fused silica materials tailored to achieve optimum properties required for molten metal applications. products are precision cast into a wide variety of sizes and shapes, from small and intricate to extremely large - even shapes with complex internal features, typically without the need for costly machining.

preformed shapes provide superior wear resistance in your most critical high flow/high velocity applications. In addition, its excellent thermal shock resistance and thermal insulation make ideal for molten metal handling.
