During steel solidification volumetric contraction occurs inside of an ingot mold, resulting in a cavity know as pipe. To minimize a depth of the pipe insulating materials are applied at the top of the ingot. To form hot top feeder head, insulating or exothermic coverings are used, in the form of plates, rings, segmented plates
Exothermic-insulating materials are used as auxiliary materials in steel foundries, cast iron foundries, non-ferrous foundries and elsewhere. Materials with exothermic and/or insulating function differ in composition, exothermic effect, insulating ability, ignition temperature, method of manufacture and other properties. For effective use of such materials, the manufacturer should be familiar with thermal properties and experimental techniques
Being aware of our responsibility towards the environment and community in which we work, we respect and strictly comply with environmental laws and regulations. All our products and services are planned, developed, produced and carried out with environmental concerns in mind. We promote and demand responsible environment management, striving for permanent improvement of environmental conditions,
Thermal insualtion coverings are pre-formed highly refractory models for thermal insulation of heads in classic ingot casting. They are made on the basis of highly refractory fillers, fibres and binders. For special needs and requirements of our customers, we develop and produce insulation coverings in insulation or exothermic-insulation quality, adjusted to reuqired shape, dimensions and
Refractory coatings are applied to sand moulds and cores in foundries (steel castings, grey cast iron and ductile iron, and non-ferrous metals). By creating a high temperature barrier over the entire coated surface between casting and substrate (mould or core), these coatings reduce the thermal shock caused by sand substrate. Coatings ensure a smooth mould
We produce insulation protective caps for steelworks. We are able to create forms and structure of insulation based on your needs – contact us with your needs on komerciala@exoterm.si Insulation protective caps are pre-formed refractory coverings that serve as thermal insulation and protection of casting stream in classic ingot mould casting.
