Refractory mixes, castables and masses
Unshaped refractories make it possible to create a jointless monolithic lining and quickly repair a damaged area. The mix is tempered with water or a binder and then cast, rammed or applied by gunning.
There is no single GOST for refractory castable mixes: they are made to manufacturers' specifications, while the classification of unshaped refractories is set by GOST 28874. We select the grade by installation method and operating temperature.
Grades and types
Refractory castable mixes
To manufacturer's specifications. Fireclay, mullite-corundum and corundum mixes for monolithic lining: they are tempered with water or a binder and cast into formwork. A jointless monolith is convenient for complex shapes and quick repairs; we choose the grade by operating temperature.
Ramming masses
To manufacturer's specifications. Masses for rammed lining of induction furnaces, troughs and repair of damaged areas. The mass is compacted by ramming, then the lining is dried and heated according to the manufacturer's instructions.
Gunning masses МШГТ, МТПФ, ТМПУ, ТМПК
To manufacturer's specifications. Gunning masses are applied with a gunning machine: this is how the lining is repaired without complete relining and with minimal downtime of the unit.
Dry refractory mixes
To manufacturer's specifications. Dry refractory mixes for laying, coating and repair. Before use they are tempered with water or a binder according to the manufacturer's instructions.

How to choose a grade
The mix is chosen by installation method and operating temperature: casting — castable mixes; lining of induction furnaces and troughs — ramming masses; repair without relining — gunning masses.
By composition, mixes are fireclay, mullite-corundum and corundum: the more alumina, the higher the operating temperature.
Frequently asked questions
To which standard are refractory castables made?
To manufacturers' specifications: there is no single GOST for refractory castable mixes. GOST 20910 covers heat-resistant construction concretes and does not apply to refractory ones.
How much mix is needed per 1 m³ of lining?
It depends on the density of the specific mix. Send us the lining volume and grade — we will calculate it from the manufacturer's certificate.
How does low-cement castable differ from conventional castable?
Low-cement castable contains less cement and therefore less calcium oxide. As a result it is denser and performs better at high temperatures. The bond type is stated in the mix certificate.
How can an enterprise order refractory castable?
Send a request with the grade, quantity and delivery city or attach a specification. We will prepare a commercial offer, sign a contract and deliver the mixes across Kazakhstan.
