Refractory castables are one of the best things which are perfectly designed and developed to create the monolithic linking of almost all kinds of furnaces and kilns. With the increasing techniques and tools used in the manufacturing products; different castable refractory manufacturer are bound to provide you different kinds of refractory castables as per their needs by client’s side.
The most common categories of refractory castable are:
- Conventional refractory castable
- Low iron-refractory castable
- Low cement refractory castable
These refractory castable are basically used for the insulating purpose in furnaces as well as kilns which can be further installed either manually or by gunning process.
These refractory castable are usually constructed from different kinds of raw materials including chamotte, andalusite, bauxite, mullite, corundum, tabular alumina, silicon carbide, perlite, and vermiculite etc. the brief details of all of the three kinds of refractory castable provided by castable refractory suppliers are:
Conventional Refractory Castable:
These types of refractory castables are prepared with high alumina cement and are quite efficient of bearing high temperature i.e. from 13000C to 18000C. This refractory castable offers a great resistance to the furnace and hence is most commonly used in common furnace applications, burner blocks, specialty muffle furnaces and boiler work etc.
When it comes to the installation process; the conventional dense castables are being installed through gunning equipment.
Insulating Refractory Castable:
Insulating refractory castable is low-density castable which includes very low thermal conductivity. It is one of the best refractory castables which is perfect to bear high-temperature work and hence can be used in backup linking being used in dense castables or brickwork.
The insulating refractory castable is perfectly designed and developed to decrease the overall density of lining. Hence, in other words, we can also say that it is one of the finest kinds of refractory castable which can be used in such places which need to withstand much wear and tear.
Low Cement Refractory Castable:
As the name explains; this kind of refractory castable is being prepared by using a lower amount of cement that being used in dense castable. This kind of refractory castable includes different types of alumina content which offers exceptional physical properties, low porosity, great abrasion properties and high vigor.
This refractory castable is free-flowing and hence can be easily pumped into position.
