Control Pins and Spouts

from Rex Materials is the ideal material for control pins and spouts for rolling ingot and billet casting operations. Its extremely fine-grained, sintered composition of high purity fused silica provides both outstanding wear properties and excellent thermal shock resistance. Special non-wetting properties, plus a factory coating of BN, prevent metal sticking and attack by aluminum and other molten metals.

The lower thermal mass and conductivity minimize the chance of freeze-ups during the start or at low metal flow rates. Our special process allows us to offer this outstanding performance at a very reasonable price.

Features:	Benefits:
Low coefficient of thermal expansion	Excellent thermal shock resistance and dimensional stability
Low thermal mass and conductivity	Thermal insulation, minimizes temperature loss
Chemical inertness	Long life, corrosion resistance
High hardness	Long life, wear resistance
Unique cast technology	Cost effective, complex shape capability
Fine Grain Structure	High strength

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, including shapes with
complex internal features – typically without the need for costly machining.

is made from fused silica that has been sintered to a high temperature. Today it is used in many non-ferrous applications, including but not limited to, tapblocks, trough liners, filter bowls, flue port blocks, pour basins, spouts, control pins, dipping ladles, stalk tubes, and dosing tubes. Rex Materials’ ability to supply quality shapes, cost effectively, enables you to use parts in applications where ordinarily fused silica products have been too expensive. Our special process allows us to offer this outstanding performance at a very reasonable price.

pins and spouts come in a wide variety of shapes and sizes. Different designs are offered to give you the best sealing capability for your particular application.
