Насто щим изобретением предлагаетс способ, позвол ющий практически устранить эти процессы и, таким образом, предотвратить порчу замесов обмазочной массы.The present invention proposes a method for virtually eliminating these processes and, thus, preventing the spoilage of the coating mass.
Этот способ заключаетс в пассивировании ферро-сплавов (ферро-марганца , ферро-силици ) путем нагрева мелкораздробленных ферро-сплавов в окислительной атмосфере при температуре 500-600°. Нагрев длитс в течение 20-30 мин. В результате этого мельчайшие зерна ферро-сплавов покрываютс оксидной пленкой.This method consists in the passivation of ferro-alloys (ferro-manganese, ferro-silicon) by heating finely divided ferro-alloys in an oxidizing atmosphere at a temperature of 500-600 °. Heating lasts for 20-30 minutes. As a result, the smallest grains of ferro-alloys are coated with an oxide film.
