Refractory concrete (thermoconcrete) ORBET-7 V with steel fibers
Product Description
REFRACTORY CONCRETE- ORBET-7 V with steel fibers
Product description and application: Refractory concrete ORBET – 7V is a mixture of high-alumina refractory raw materials, refractory cement and steel fibers, 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 and additives.
Preparation: Before wetting, dry mixing is recommended 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 humidity 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 temperature increase rate from 150-650°C is 15°C/h, and from 650°C to the operating temperature is 50°C/h.
