Castables is a dry materials that can be combined with water to form a homogenous mass which can be cast in formwork similar to concrete.
Castable refractories can be classified into four major groups - dense castables, lightweight or insulative castables, gunning castables, and special purpose castables - sometimes these classifications can be combined, such as lighhtweight gunning castables, or dense gunning castables.
Dense castables are designed for strength, abrasion and corrosion resistance and are primarily used as the working hot face.Lightweight insulating castables provide low thermal conductivity values behind dense castables, or in certain conditions as working hot face linings.Gunning castables are modified versions of the above castables that allow them to be effectively placed using pneumatic guns. Some grades are dual purpose, allowing both casting and gunning without change.Special duty castables feature specifically enhanced properties over conventional castables, such as the modern range of low cement castables and castables with less conventional binders.
As part of our range of materials we are able to offer a range of castables to complement most applications. The dense castable range of materials we supply are made from selected raw material, aggregates and cements. The careful selection of raw material provide goods in this range with a range of properties and characteristics.
Standard Dense Castables are ues in range of material to cover the range of temperatures from 1400 C to 1800 C. These products are the most suitable for a wide range of applications ranging from boiler work, general furnace applications, burner blocks to specialty muffle furnaces. As part of this range we carry 1450, 1600 and 1650 grades for the majority of general castables work.
Gunning Castables are selected of specialty raw material is used to produce a range of Gunning Refractory. This material is mixed with water at the nozzle of the gunning equipment to enable easy placement of castable. This method is very suitable for placement of bulk material in applications where conditions make formwork unpractible or too time consuming. The temperature range varies from 1400C to 1800C to suit most applications.
Low Cement Castables has range of castables with lower cement content than standard dense castables. Varying in Alumina content these products have excellent physical properties. Low porosity, high strength and good abrasion resistance are features of low cement castables. Generally these products require controlled installation including mixing, water addition and high frequency vibration placement.
Abrasion Resistant Castables are use where conditions are extreme a range of Abrasion resistant dense castables are available. These castables are available as Gunning and Low Cement as well as in the Conventional style of castable.
Insulating Castables as the name describes we supply a range of castables with specialty materials and low densities. These products range from materials with temperatures of 1000C and densities of 400kg/m3 up to 1750C with densities up to 1850 kg/m3. Insulating castables are used as either a back up lining or for hot face work. As a back up lining they can be found behind brick work or behind dense castables where protected they help to reduce the overall density of the lining or to reduce the cold face temperature to something suitable for people to work near. As a hot face they are used in areas where wear and tear is not generally a problem. There low density generally means that the insulating range of castables have only low to medium strength making them not suitable to abrasion or particle attack. As a hot face they are used in boilers and furnaces where they are not subjected to punishment.
This Castable is suited for Medium Castable Insulation, High Castable Insulation. This Castable is use by the Fire Bricks for constructing of the Kiln, Furnaces, Ovens, Tunnel Kiln, Shuttle Kiln, Oil Fired Furnaces etc and all types of Reractories and Refractory lining. Castable is also use for patching of certain area from where hot air can be sealed. Castable is also used in a place of Insulation. This all the Products are been Manufacturer, Export, Wholesale, Supply, with many Dealers.
