Low Cement Castable Properties

Low-cement, ultra-low cement refractory castables refer to castable refractories with a calcium aluminate cement addition of less than 8%. According to the American ASTM regulations, the CaO content in low cement castables is less than 2.5%, generally between 1.0% and 2.5%. When the CaO content is less than 1.0%, it is called an ultra-low cement castable. Unlike ordinary refractory castables, some or most of the calcium aluminate cement in the matrix of low cement and ultra low cement castables is replaced by ultrafine powder with the same or similar chemical composition as the main material. At the same time, an appropriate amount of dispersant (water reducing agent) and a certain delayed coagulant are added.

Low cement castables refractory material has the merits of high density, low porosity rate, good hot strength, high refractoriness and high refractoriness under load. Besides, the low cement refractory castable has strong mechanical spalling resistance, shock resistance and corrosion resistance ability. 

• High density
• Low porosity rate
• Good high temperature strength
• High refractoriness
• High refractoriness under load
• Strong in mechanical spalling resistance, shock resistance and corrosion resistance.

Lightweight Insulating Castable Refractory

The Lightweight Castable Refractory is a castable unshaped refractory material prepared by adding water or a solution containing a binder during construction by using light refractory aggregate, refractory powder, binder and admixture. It is generally used as a thermal insulation lining for thermal equipment to reduce energy consumption by heat preservation. Therefore, it is also called Lightweight Insulating Castable Refractory.

Lightweight Insulating Castable Refractories Features

Lightweight Insulating Castable Refractories have good thermal insulation properties due to their small bulk density and low thermal conductivity. At the same time, lightweight insulation refractory castables have other unique features for thermal insulation lining of various thermal equipment, and some lightweight castables can also be used directly for work lining.

• Feature 1: Light weight, high compressive strength, acid and acid gas corrosion.
• Feature 2: heat insulation, heat preservation, low water absorption
• Feature 3: Simple construction, it is the most ideal product for the construction of alkali corrosion resistant parts under high temperature.
• Feature 4: Good workability, strong adhesion, long initial setting time and long operation time, strong strength growth, strong impermeability, no need for acid treatment, easy to ensure the dense and fullness of masonry gray joints, can significantly improve The airtightness and integrity of the lining wall of the chimney and the corrosion resistance of the lining are ideal cementing materials for high chimneys, high temperature flue and duct lining, and can also be used for acid resistant pools in petroleum, chemical, nonferrous metallurgy and other industries. Acid resistant engineering such as tanks.

Lightweight Insulating Castable Refractory can be classified according to the use temperature:

• Low temperature lightweight refractory castable with a temperature of 600-900°C;
• Medium temperature lightweight refractory castable with a temperature of 900-1200°C;
• High temperature lightweight refractory castable, use temperature greater than 1200°C.

This kind of lightweight insulation castable has the properties of lightweight, good performance of insulation, and low thermal conductivity.

Castable Refractory Cement Manufacturer

The raw materials of high-quality bauxite and high-quality lime are mixed in a certain proportion; after sintered, the clinker with aluminate as the main component is obtained; the clinker is further ground into fine powder; Finally, a fire-resistant hydraulic cementitious material called Castable Refractory Cement is produced. Refractory Cement has a refractoriness of not less than 1580°C. According to the composition, it can be divided into alumina refractory cement, low calcium aluminate refractory cement, calcium magnesium aluminate cement and dolomite refractory cement.

Use of Refractory Cement

Refractory cement is also be called furnace cement. Refractory cement can be used to bond various refractory aggregates (such as corundum, calcined high alumina bauxite, etc.) into refractory mortar or concrete for lining of cement rotary kiln and other industrial furnaces.

Precautions after Construction of Refractory Cements Lining

After the refractory cement lining is completed, an boiler-drying is required to evaporate excess water. Avoid the explosion of the boiler when start-up operation, and extend the service life of the refractory lining.

When the refractory cement lining is on baking, it should be slowly heated to avoid excessive temperature rise to prevent local bursting. When it comes to cooling of the refractory cement lining, it should also be slow, and avoid forced ventilation.
