Refractory concrete (thermoconcrete) ORBET-4 V with steel fibers
Product Description
REFRACTORY CONCRETE- ORBET-4V
Product description and application: Refractory concrete ORBET – V is a mixture of high-alumina refractory
raw materials and refractory cement with the addition of steel fibers, it is very suitable for the production and maintenance of refractory linings of thermal
aggregates such as industrial furnaces or household furnaces, because they achieve high strength in a short time.
Composition: Refractory cement, fireclay, additives and steel fibers
Preparation: Before wetting, it is recommended to mix in a dry state for homogenization. Intensive mixing and wetting is carried out for 3-4 minutes in a clean mixer or on a suitable concrete surface, without residues from previous
mixing. The required addition of water depends on the installation method and ranges from 7-10%. For the production of more complex forms, the moisture content of the concrete is increased by 2-4%. Adding water in larger quantities is not recommended due to the formation of
possible cracks during drying.
Properties: High refractoriness, high strength and fast setting.
Installation: Installation of thermoconcrete is carried out by tamping or vibrating. Thermoconcrete is carefully tamped into
a set template, made of smooth boards and coated with a protective coating. The process of setting thermoconcrete
is accompanied by the release of heat, therefore it is necessary to cool the refractory wall with water. If the refractory wall rests on
a material that easily absorbs water, it must be insulated with plastic foil. Under normal conditions, concrete sets in
15-20 minutes, and hardens in 24-48 hours. Concrete should be installed at a temperature of 5-30°C. After the prescribed setting time, dry the lining for 2-3 days at 150°C. The rate of temperature rise from 150-650°C is 15°C/h, and from
650°C up to an operating temperature of 50°C/h.
