Zircar Refractory Composites, Inc. has introduced its Type RS-202
refractory sheet cylinders. According to the company, this product
was developed as a cost-effective replacement for dense mullite
tubing in an induction-annealing machine. RS-202 is reportedly a
lower cost cousin of the company's RS-201 cylinders, delivering the
same performance but at a more cost-effective price. Both products
are medium density reinforced alumina composites with a maximum use
temperature of 1260C. Unlike RS-201, which has a smooth burnished
outer diameter, the exterior surface of RS-202 more clearly reflects
the weave of its reinforcing material. It was developed for use as a
high temperature, thermal shock resistant electrical insulation
material in an inductively heated tube-annealing machine. Market
reports show that RS-202 lasts three times as long as the dense
mullite tubing previously used, according to the company.
