Thermal insulating materials for steelworks and foundries

Development, Products

Thermal insulating materials for steelworks can be divided into three groups:

1. insulation coverings,

2. cast stream protection coverings,

3. exothermic insulating agents.

They are based on highly refractory ¬fillers, fibers and binders.

Insulation coverings are pre-formed highly refractory models for thermal insulation of heads in classic ingot mold casting in shapes of segmented coverings, rings, plates and inserts. Material can be insulating or exothermic insulating.

Cast stream protection coverings are pre-formed refractory coverings that serve as thermal insulation and protection of casting stream in classic ingot mold casting.

Exothermic insulating agents can be produced in powder form or as solid covers, applied at the top of ingot heads. Products react highly exothermically in contact with melt, dissipating heat to inner side of the ingot head. Residual after burning is highly porous, ensuring good insulation characteristics.

Company EXOTERM-IT is producing all three types of thermal insulating materials. Products can be developed and produced according to special needs and requirements of customers, to obtain required shapes, dimensions and functionality of the products.

Benefits of the use of exothermic insulating materials during ingot casting process

Development, Innovation, Products

The benefits of the use of exothermic insulating materials during ingot casting process are presented on the animation below. Different insulating products were applied at the top of the mold during teeming and solidification. MAGMASOFT® casting simulation software was used to show the difference between uninsulated (left side of the animation) and insolated mold (right side). The difference is obvious. While uninsulated mold creates deep pipe, the well-insulated mold prevents occurrence of the pipe and create almost flat top surface.
