Abstract

Under study was the reaction of the basic operating performance of the cold low-shrinkage ramming paste (CRP) on the pre-heating conditions of the rammed joint. It was found out that the uncontrolled high-rate heat-up of the cold ramming paste (CRP) loosens the macrostructure and intensifies impregnation of the rammed layer. The controlled delayed rate in the temperature rise of the inter-block joint up to 400 °С enables to obtain a high-quality layer of paste with the improved barrier properties against its impregnation with electrolyte

Исследовалась реакция основных эксплуатационных свойств массы холоднонабивной низкоусадочной МХНУ на режимы предварительного разогрева уплотненного шва. Установлено, что неконтролируемый высокоскоростной разогрев МХНУ разрыхляет макроструктуру и интенсифицирует пропитку уплотненного слоя. Контролируемый замедленный темп подъема температуры межблочного шва до 400 °С позволяет получить качественный слой массы с улучшенными барьерными свойствами против пропитки электролитом
