Rotary Furnace

Filtech International offers state of the art Rotary furnaces. Used for melting all kind of metals with high energy efficiency, high metal yield, high productivity, the possibility of with low quality scrap including dross, high automation of recycling process, reduces or elimination of metal “contaminated” with harmful impurities (for example iron) 

Insulation Refractory Material

Insulation Refractory Bricks, also called insulating fire bricks, is a kind of hot-sale refractory fire bricks and also a kind of quality refractory insulation materials, which can be used to save energy for the insulation layer in the kiln or furnace. Insulation Refractory Bricks have low heat storage and low thermal conductivity.

Description for Insulation Refractory Bricks

Insulation Refractory Bricks are manufactured for as wide application in furnace, kiln, oven, ceramics, fire protection and other industries, which can resist high temperature from 1093~1760℃. Each type of insulation refractory bricks is formulated to meet specific thermal and physical requirements and is made of high purity fire clay and other ceramic raw materials through firing after molding in the high temperature. Different grades of insulation refractory bricks are made according to international standards, and are suitable to operate in various temperatures and atmospheres up to 3000º F.

Application of Insulation Refractory Brciks

Insulation Refractory Brick can be used in many fields of industries such as Iron & Steel Industries, Ceramics Industries, Glass Industries, Non-Ferrous Metals Industries, Power Generation Industries, Electrolytic Aluminum Industries.

Commonly Used Refractory Materials for Rotary Kilns

Aluminum-silica series refractory bricks mainly include alkali-resistant series bricks, high-alumina (anti-stripping) series bricks, silicon-mo series bricks and so on.

The upper transition zone of the rotary kiln is close to the firing zone and the firing zone. The flame temperature of the lining can reach up to 2000℃, and the temperature of the material can reach 1350~1400℃. In addition, it must withstand the penetration of sulfur-alkali compounds. Material melt (liquid phase) penetration and thermal shock, redox, cylinder elliptical deformation and other mechanical stress effects.

Therefore, this is the part where the lining bears the most severe stress, and only alkaline refractories can meet the requirements for use under this condition.

Mullite Insulation Brick has features of light weight, low thermal conductivity, thermal insulation and high compression strength and can be used for the top of hot blast stove, stack and bottom of blast furnace, regenerative chamber of glass melting furnace, lining of ceramic high temperature furnace and so on.

Silica Insulation Bricks can service in the high temperature between 1500~1550℃ for long term and are wildly used for the insulation of industrial furnace such as glass plant furnace and other furnaces & boilers with features of light weight, high strength and low thermal conductivity.
