Refractory Monolithics

High purity dense castables are refractory castables suitable for high temperature applications, all of which contain high purity refractory cement CAL-AL-75 as the refractory binder.The impurity levels of all these castables are very low.These castables are available in various grades. Each grade of castables is suitable for a specific range of operational conditions.

These refractory castables are hydraulic setting and can be cast or moulded to any shape and can also be suitably modified for gunning of furnace linings. The WHYTHEAT range of castables are one of the most efficient in the market.

The high alumina binders, used for making refractory castables, are calcium aluminate cements. ACE produces three grades of high alumina binders - Calundum, Cal-Al-75 & Cal-Al-85. Calundum, a medium purity high alumina refractory binder, sets hydraulically and when used with refractory aggregates, provides a high strength refractory castable.

Cal-Al-75, a high purity refractory binder,sets hydraulically and when used along with refractory aggregates,provides a refractory castable of superior strength.

Calderys offers a range of insulating castables in the INSULYTE series to conserve heat in furnaces.They are light but adequately strong, and have low conductivity, thus serve as either hot face or back- up insulating refractory lining.

INSULYTE castables are produced in the density range of 400 to 1600 kg/m3.They are available mainly in two different grades - medium purity and high purity. In addition to standard products,tailor-made compositions are also supplied to suit customer requirements.

Medium purity dense castables are mainly the FIRECRETE brand refractory castables; these are suitable for use in medium temperature applications.This group of castables contains medium purity cement Calundum as the refractory binder.Depending on the type of refractory aggregates used in these castables, a series of FIRECRETE group of castable are manufactured.All these castables are used in oxidising atmospheres only. These refractory castables are hydraulic setting and can be cast or moulded to any shape,and can also be suitably modified for gunning of furnace linings.

MORTARS are joining materials for laying refractory bricks.Calderys produces a wide range of fireclay and high alumina mortars. These mortars are used as joining materials for various insulation and high alumina bricks. Mortars like Accoset 50,Mortar 70 are suitable for different types of insulation/fire bricks.

Some of the mortars are supplied as two component system,where liquid binder is separately provided with powder material. Where water is used as liquid component,the amount of water used should be such that it results in troweling consistency.

ACCMON is a series of low cement castables, having high PCE and high strength at all temperature levels.These castables are favoured in locations, where refractory abuses due to abrasion as well as application temperature are very high.These have low lime content, low porosity and high strength.
