Product Description

MYREAL calcium silicate shaped blocks are machined from MY270 dense board, which carries 0.65 MPa compressive strength and 0.33 MPa flexural strength with dimensional stability within 1%. They are made to your drawing for furnace doors, burner openings, pipe penetrations and irregular equipment surfaces where a flat board cannot follow the furnace geometry, and hold their shape at 650 C service.

Application

Specified where the lining has to follow a shape that flat board cannot cover, and where the part must resist knocks during erection and service.

  • Furnace door and burner opening blocks
  • Pipe and duct penetration pieces
  • Irregular shell and casing lining segments
  • Support and spacer blocks in furnace lining
  • Replacement parts for worn lining on existing furnaces

Key Advantages

  • Machined to your drawing, so complex geometry needs no on site cutting.
  • MY270 grade gives 0.65 MPa compressive and 0.33 MPa flexural strength.
  • Dimensional stability within 1% holds the fit through thermal cycling.
  • Class A1 non-combustible with no flame spread and no dense smoke.
  • Low chloride ion content, safe for stainless steel adjacent parts.

Standards and Compliance

  • Manufactured to GB/T 5486 calcium silicate products standard under an ISO 9001 certified quality system
  • GB/T 8624 Class A1 non-combustible, no flame spread and no dense smoke
  • Low chloride ion content protects stainless steel and alloy pipework from chloride stress corrosion
  • Low water absorption, performance is not affected by humidity
  • Free of formaldehyde, benzene and other harmful substances

Installation Notes

  • Dry fit the block against the shell before fixing to confirm the shape.
  • Keep the designed expansion gap between adjacent blocks.
  • Fix with stainless steel anchors or ceramic studs matched to the block thickness.
  • Seal joints with a matching high temperature mortar where a continuous lining is required.
  • Do not cut or drill on site beyond the drawing allowance.

FAQ

Q: Can you machine the block to our drawing?
A: Yes. Shaped parts are machined from MY270 board to your drawing, including curves, steps and cut outs. Send a drawing with dimensions and we will confirm the block layout.
Q: What thickness can a shaped block have?
A: From 20 mm to 100 mm, taken from the MY270 board stock range. Thicker sections are built up from layers and fixed together.
Q: Why use a shaped block instead of flat board?
A: A flat board leaves gaps at curves, openings and penetrations, and those gaps become hot spots. A machined block fills the geometry exactly and keeps the lining continuous.
Q: Does the shaped block resist load?
A: Yes. MY270 carries 0.65 MPa compressive strength, so it can be used for support blocks and spacers as well as pure insulation.
