Changes in kinetics of hardening the furan-chromite mixtures exposed to extreme temperatures

In foundries of metallurgical character it is difficult to ensure an acceptable climatic working environment during winter season. It is connected with explosing the raw materials (binders, hardeners) and mixtures to extreme temperatures. The contribution deals with kinetics of harding the furan-chromite mixtures in the temperature range of +20 - -6oC, changes during storing, following fast heating (during drying the moulds), the mixture moisture and the action of water coatings, and also the changes of binding effects of furan binders when storing them under down to - 16oC.
