Abstract (en)

[origin: EP0428964A2] The invention relates to a dome-forming sliding gate-sealant mass such as is used for protecting the closing gate of the outlet opening of casting ladles. It has been found that the flowability of a sliding gate-sealant mass based on quartz sand and chromium ore sand can be improved if carbon in the form of a carbon black of defined fine particle size distribution is added thereto. Improved flowability ensures that the sealant mass clears the casting opening without hindrance when the sliding casting gate is opened.
