High Alumina Refractory Castable Cement Maxheat K (1600 degrees) in Nairobi Kenya

Kenworks Ventures holds in stock High Alumina Refractory Castable Cement Maxheat K (1600 degrees) in Nairobi Kenya.

Castable refractory cement has chemical and physical properties used for creating heat-resistant structures that retain and insulate. Due to their high resistance to heat and thermal shock, you can use castable refractory cement and other products to build kilns and furnaces. Refractory castables can be used to create the monolithic linings within all types of furnaces and kilns.

Another common High Alumina Refractory Castable is MaxHeat A from Mahakoshal Refractories and PVT Limited which can withstand temperatures of 1750-1810 degrees. It has 90% Alumina Content.

Description

REFRACTORY CASTABLES

Castable refractory products are non-metallic materials that have chemical and physical properties used for creating heat-resistant structures that retain and insulate. Due to their high resistance to heat and thermal shock, you can use castable refractory cements and other products to build kilns and furnaces. Refractory castables can be used to create the monolithic linings within all types of furnaces and kilns. They can be further classified into the following sub-categories: conventional, low iron, low cement, and insulating for installation either by gunning or manually. There is a wide variety of raw materials that refractory castables are derived from, including chamotte, andalusite, bauxite, mullite, corundum, tabular alumina, silicon carbide, and both perlite and vermiculite can be used for insulation purposes.

  1. CONVENTIONAL DENSE REFRACTORIES

Conventional dense castables are created with high alumina cement, and can withstand temperatures from 1300oC to 1800oC. These refractory castables are great for common furnace applications, burner blocks, speciality muffle furnaces and boiler work. Resistance is a key quality that varies with the choice of materials, resulting in abrasion, thermal shock and slag attack. Casting and gunning techniques are the method of installing the materials. For the ease of castable placement, gunning materials and water are combined together at the gunning equipment’s nozzle. This is a great method of placement for bulk materials, in cases when circumstances make formwork overly time consuming or simply impractical. In general, the method of installation will depend on cost and accessibility.

  1. INSULATING 

Another product that we supply is the castable refractories that are low density. These insulating castables pose very low thermal conductivity and are utilized for either high temperature face work or when used for a backup lining, which is found behind dense castables or brick work. Here, the insulating castables are able to decrease the lining’s overall density or the cold face temperature. Their strength, which ranges from low to medium, is based on the fact that their density is low and is the main reason that they are not resistant to abrasion. They are most suitable where they do not have to stand up to much wear and tear.

iii.    LOW CEMENT

This type of refractory castable is prepared with a lower amount of cement than the standard dense castable is normally created with. Low cement castable refractories fluctuate in alumina content, which provides exceptional physical properties, including low porosity, great abrasion properties and high vigour. These products will commonly necessitate installation that is controlled, however, the big advantage of low cement castables is that they are easily pumped into position, and some may not require vibration, because they are free flowing.
