General Info

ZIRCAR Refractory Composites Inc., provides a variety of non-asbestos calcium silicate structural insulations that combine high strength and excellent thermal insulating characteristics for use in a variety of heat processing, fire protection and electrical resistance applications. The unique calcium silicate structure provides excellent thermal shock resistance as evidenced in its typical use as a direct contact board for non-ferrous metals and in fire training burn rooms. They are fire resistant to temperatures approaching 1100°C(2012°F). They also exhibit low thermal conductivities that remain relatively constant over a broad range of operating temperatures.

ZIRCAL-95

ZIRCAL-95 is ideal for machining to tight tolerances.

Type ZIRCAL-95 Refractory Board is produced from a combination of natural organic fibers and inert reinforcing fillers in a high density calcium silicate hydrate matrix. Designed as a substitute for asbestos cement boards, ZIRCAL-95 is useful as structural and electrical insulation in applications with temperatures to 1100°C(2000°F).

ZIRCAL-95’s surface is sanded smooth. It has a uniform consistency making it a useful source for custom machined insulating parts.

ZIRCAL-95 combines low thermal conductivity and good dielectric properties with high mechanical strength. It is hygroscopic and contains a small amount of moisture. For certain high temperature electrical insulation applications, ZIRCAL-95 should be thoroughly dried for 24 hours at 100°C-150°C. It is ideal for use as press platen insulation, foundry core and blow plates, induction furnace casing, electrical resistance insulation, hot glass handling, as well as many others.

Composition

  • Thermal shock resistance and stability – will withstand continuous heat up to its full temperature limit.

  • A consistently low thermal conductivity means high energy savings.

  • High structural strength at elevated temperatures – retains full integrity across a broad range of temperatures.

  • Incombustible – ideal for personnel protection, cable trays, fire doors, and marine applications.

  • Easily machined to tight tolerances with conventional tooling.

FABRICATION INFORMATION

Zircal-95 has unique machining characteristics. It is easily cut with hand held woodworking tools using slow cutting action. Operator will notice the rate of material removal decreases as increased force and tool speed is applied. When sawing by hand, a slow steady motion works best. Zircal-95 has been successfully machined using power equipment with the following parameters:

  • Sawing: Diamond wheel, approximately 250 mm diameter with 12 mm long teeth spaced 25 mm apart, 1800 RPM.
  • Milling: Double edge carbide end mill, speed approximately 4000 RPM , feed rate – 4 m/min.
  • Turning: Carbide tipped tools used on 50 mm diameter part at 1200 RPM, feed rate – 4 m/min.
