The refractory materials for acid furnaces produced by our company mainly include the following types:
Corundum Refractory Castable
Corundum refractory castable is made of fused corundum, ultrafine alumina powder, pure calcium aluminate cement and various additive binders. It is a high-grade high-purity refractory castable that can only be used after on-site vibration construction and baking.
Corundum Mullite Castable
Corundum-mullite castable is made of fused corundum, mullite, special high-alumina bauxite, industrial chromium oxide, ultrafine alumina powder, pure calcium aluminate cement and various additive binders.
Lightweight Insulation Castables For Acid Furnaces
Lightweight insulation castable, also called insulation castable, heat-insulating castable, is a refractory insulation castable carefully formulated with lightweight aggregate, high-aluminum porous aggregate, high-temperature binder, admixture, etc., with a bulk density generally less than 1.8g/cm3.
Benefits of Refractory Materials For Acid Furnaces
You Cannot Get a Better Heat-Resistant Cement Than This
Refractory materials for acid furnaces is very popular among oven and furnace designers for its heat-resistant properties. This stuff can handle temperatures at which other regular cement or mortar breaks down.
You Will Get Flexibility In Design
As this cement mixture has a texture like any other cement, thus can be easily molded, poured, or made into any shape you wish. You can get a specific shape or line an area with heat-resistant refractory materials for acid furnaces like never before.
Durability That Lasts For Years
In addition to its heat resistance property, the texture of this cement is also resistant to extreme wear and tear which makes it one of the best choices for industrial settings and high-working areas. With that, it is also thermal shock resistant meaning it won’t crack or break with quick temperature changes.
Saves Lots Of Money
Refractory materials for acid furnaces traps heat inside the structure which makes it more energy-efficient. Imagine, installing a kiln or oven with this material and saving a lot of your resources by keeping the furnace hot for longer. A good choice for both your wallet and environment!
Application of Refractory Materials For Acid Furnaces
Steel Industry
Refractory Materials are heavily utilised here. For lining blast furnaces, converters and even ladles. They protect them from the extreme heat that is required to process molten steel. Without these linings, equipment would deteriorate rapidly, leading to costly repairs and downtime.
Cement Industry
And this reciprocates to where they are used, for example, in rotary clins. They help maintain structural integrity and prevent wear and tear. It ensures a seamless production cycle in one of the most demanding industrial processes.
Glass Manufacturing
The glass industry relies heavily on these materials for suitable results. They are used extensively to line furnaces & tanks.To protect them from thermal stress in the production phase of course. These materials can easily withstand high temperatures that are commonplace in this industry.
