Anchor-Tech 1500℃ type ceramic fiber composite module

Types of 1500℃ ceramic fiber composite modules

Chrome module

It is made of folded chromium-containing fiber blankets and has good high-temperature stability. The module density is ≥230Kg/m3.

Chromium + zirconium composite module

The outer layer of the hot surface is a chromium-containing blanket , and the inner layer is a zirconium-containing blanket . This form gives full play to the respective advantages of chromium-containing and zirconium-containing blankets and can save some material costs. However, the difficulty of production and processing increases. Module bulk density ≥220Kg/m3

Chrome+Felt composite module

Sliced module : taking advantage of the high temperature resistance of chrome blankets and the low shrinkage and good resilience of Felt products. Reduce the occurrence of shrinkage gaps. Module bulk density ≥220Kg/m3

Enhancement of 1500 composite modules

In order to improve the service life of the furnace lining , we will upgrade the 1500 composite module. The main measure is to treat the surface or expansion joints of the furnace lining with high-temperature coatings .

Particularly recommended application areas

1. Forging heating furnace

2. Coking oven door

3. Furnace types for 1250C working conditions in the metallurgical industry
