REPCAST HR is a ceramic composite developed by ALEASTUR which combines a high temperature ceramic refractory with up to 30% weight stainless steel fibers. This combination result in a product with excellent properties in comparison with steel or cast iron shapes and other reinforce monolithic refractories.
REPCAST HR can be applied in different areas where metals are oxidized at high temperature and refractories do not wear mechanical impacts or abrassion.
REPCAST HR is designed for each industry using different combinations of ceramic materials and stainless steel fibers in a wide range of geometries according to each customer’s particular specifications.
REPCAST HR has some inherent properties that allow itself to work in most difficult conditions regarding high temperature and impacts. These properties are:
High Termal Stress Resistance
High Impact Resistance
High Thermal Shock Resistance
High Oxidizing Atmosphere Resistance
Instalación y colado
REPCAST HR is supplied as a precast shape according to customer’s design and geometries, but in some special applications it can be cast in situ.

Steel industry has many stages where impact and abrassion resistance is an essential need.
ALEASTUR has developed REPCAST HR to fully comply with such requirements, getting satisfactory results in applications like:
Drilling machine baking
Drilling machine support
EAF slag doors
Hot metal transfer ladle spouts
Ladle lip rings
Quenching car ramps
Torpedo car throats
Coke oven ramps
Non ferrous industries
EPCAST HR has been used successfully in the non ferrous metallurgical industries such as aluminium, zinc, copper, etc., and mineral industries including cement, lime, petrochemical, incinerators, etc., with a wide range of applications, like:
MG charging tools
Furnace door jambs, sills & lintels
Furnace door perimeters
Jambs, sills & lintels
Lime & cement kiln lifters
Thermocouple protection tubes
