2.Low heat storage results in rapid cooling and heating operation
3.Low iron and impurities to enhance reducing atmosphere
4.thermal shock resistance in preventing spalling
5.Non standard sizes and shapes are available upon request

Application:

Ceramic shuttle kilns
Metal heat treatment furnaces Steel billet reheating furnaces Oil refinery heaters
Laboratory furnaces
