FIELD: production of building materials.
SUBSTANCE: method of ceramic article treatment in shaft-furnace includes row-by-row charging articles on sole with firming parallel through channels; feeding coolant to charge and unloading the ready articles. Charge is formed such that articles of each next row are offset relative articles of previous row. Upper article is places on lower article such that contact area between two articles includes projected article centers of gravity. Charging scheme is repeated along charge height. Articles are unloaded in row-by-row manner. Unloading device has mechanism for charge fixation formed as frame with inner support members arranged under charge channels and following mechanism. Following mechanism is made as lifting-dipping panel with holders arranged on lifting-dipping panel such that pattern of holder distribution over lifting-dipping panel repeats distribution pattern of contact areas between articles in charge. Unloading device includes article extraction means formed as set of leaf chains located under panel such that holders may pass under leaf chains.
EFFECT: increased article quality.
