Refactory Cement/Fireproof cement
At Olinc Industrial Products & Equipment Ltd, we are the market leaders in the supply of fire cements in Kenya, and East African Region.
Refractory cement in Kenya is a type of hydraulic binder that is resistant to high temperatures and is used for applications that involve exposure to extreme heat or fire. This type of cement is designed to withstand and retain its structural integrity in environments where traditional cement would break down or fail due to the effects of heat.
Refractory cement contains high alumina content and other properties that make it possess thermodynamic properties suitable for high temperature conditions. The fire cements are made with minerals like aluminium oxide to bind the coarse aggregates in the cement thereby increasing the thermodynamic properties of the cement, making it temperature resistant and good formability.
Types of Refractory cement in Kenya
There are various types of refractory cement in Kenya. Olinc Products and Equipment Ltd supplies the 3 main types refractory/fireproof cement in Kenya. These are Fondu Cement, Maxheat K and Maxheat A. The three types of cement are classified according to their alumina content which determines the range of temperature which they can withstand.
Maxheat K -1600°C (60%-Alumina)
One of the most common refractory cement in Kenya is Maxheat K. It is premixed refractory compositions which can cast into any require shape and size. It is mostly preferred due to its high thermal and shock resistance.
MaxHeat K Specifications
- Material: – Refractory Castable
- Type: – 56% Min – 60% Max Alumina Dense castable
- Nature of Bond: – Hydraulic
- Installation: – Vibration Casting
- Service Temperature: – 1600°C
- Maximum Grain Size: – 5 mm
- Water required for casting: – 11 to 12.5%
Applications of Maxheat K in Kenya
Maxheat K fire cement in Kenya is applicable in General purpose uses, Blast furnace, Foundries, Forge furnace, Tunnel kilns, Heat treatment furnace car tops, Electro phosphorus furnace, Sock pit cover construction etc.
Maxheat A -1750°C
Maxheat A is a castable cement in Kenya suitable for high temperature applications. Just like Maxheat K It is premixed refractory compositions which can cast into any require shape and size. It is mostly preferred due to its high thermal and shock resistance.
MaxHeat A Specifications
- Material: – Refractory Castable
- Type: – 88% Min – 90% Max Alumina Dense castable
- Nature of Bond: – Hydraulic
- Installation: – Vibration Casting
- Service Temperature: – 1750°C
- Maximum Grain Size: – 5 mm
- Water required for casting: – 9 to 11%
Applications of Maxheat A in Kenya
Maxheat A is applicable in General purpose uses, Blast furnace, Foundries, Forge furnace, Tunnel kilns, Heat treatment furnace car tops, Electro phosphorus furnace, Sock pit cover construction etc. However, its service temperature is higher than that of Maxheat K.
Max-50 (Fondu Cement)
CIMENT FONDU® is a calcium aluminate-based hydraulic binder and contains calcium silicates, as opposed to Portland Cements. Its has the properties of high early strength and good refractoriness.
Fondu Cement Properties
- High temperature resistance (up to 1000°C)
- Has 3 to 30 minutes setting
- Corrosion Resistance (pH ≥ 4)
- Suitable in very temperatures (-10°C)
- Quick activity resumption (activities can be resumed after 6 hours
Applications of Refractory/Fireproof cement in Kenya
Fireplace Construction:
- Refractory cement is commonly used in the construction and repair of fireplaces and chimneys due to its ability to withstand high temperatures.
Kilns and Furnaces:
- Refractory cement is used to line kilns and furnaces in industries such as ceramics, glass, and metalworking, where high temperatures are involved.
Foundries:
- Foundries use refractory cement to create linings for crucibles, ladles, and other equipment exposed to molten metal.
Boilers and Incinerators:
- Refractory cement is applied in the construction and maintenance of boilers and incinerators to withstand the heat generated during combustion.
Industrial Ovens:
- Refractory cement is used to line the walls and floors of industrial ovens, a good example is Pizza ovens in Kenya, ensuring they can endure the high temperatures required for various manufacturing processes.
Metal Processing:
- Refractory cement is utilized in industries involved in metal processing, including steelmaking and aluminum smelting.
