Description

Изобретение относитс  к черной металлургии , в частности к производству кладочных работ в купольной части высокотемпературных воздухонагревателей дл  доменных печей с внутренней камерой горени .The invention relates to ferrous metallurgy, in particular, to the production of masonry work in the dome of high-temperature air heaters for blast furnaces with an internal combustion chamber.

Наиболее близким к описываемому изобретению по технической сущности и достигаемым результатом  вл етс  способ кладки купола воздухонагревател  с теплоизол цией его слоем легковесного кирпича l1.The closest to the described invention by its technical essence and the achieved result is the method of laying a hot-air dome with its thermal insulation by a layer of light-weight brick l1.

Кладка теплоизол ционного сло  основного купола производитс  непосредственно на огнеупорную кладку. Такой способ кладки основного купола позволил достичь температуры купола 1450 С, температуры гор чего, дуть  1150 С.The laying of the heat insulating layer of the main dome is made directly onto the refractory laying. This method of laying the main dome allowed the dome to reach a temperature of 1,450 ° C, a hot temperature of 1150 ° C.

Однако такой способ кладки основного купола высокотемпературного воздухонагревател  не позвол ет избежать воздействи  сил термического расширени  огнеупорной кладки основного купола при разогреве .However, this method of laying the main dome of a high-temperature air heater does not allow one to avoid the effects of thermal expansion forces of the refractory masonry of the main dome during heating.

С повышением температуры купола до 140О-1550 С такой теплоизол ционнь 1Й слой не обеспечивает надежной илол дии брони кожуха воздухонагревател  в верхней его части.With an increase in the temperature of the dome to 140–1550 ° C, such a heat insulating 1st layer does not provide reliable illidium of the heater’s casing in its upper part.

Это приводит к коррозии или разрыву брони и, как правило, к преждеврюменной остановке воздухонагревател  на ремонт.This leads to corrosion or tearing of the armor and, as a rule, to a premature stopping of the air heater for repairs.

Целью изобретени   вл етс  избежание разрушени  теплоизол ции основного купола и сокрашение потерь тепла в верхней части высокотемпературного воздухонагревател  при термических воздействи х .The aim of the invention is to avoid the destruction of the thermal insulation of the main dome and the reduction of heat loss in the upper part of the high-temperature air heater during thermal effects.

Поставленна  цель достигаетс  тем, что по предлагаемому способу кладки, включающему огнеупорную и теплоизол ционную кладки, кладку теплоизол ционного и огнеупорного слоев выполн ют с зазором , который во врем  производства кладочных работ заполн ют древесными опилками.This goal is achieved by the fact that according to the proposed method of masonry, including refractory and insulating masonry, the insulating and refractory layers are laid with a gap, which is filled with sawdust during masonry work.

Древесные опилки позвол ют сохранить необходимый и достаточный зазор в период производства кладочных рибот, исклю-Sawdust allows you to maintain the necessary and sufficient clearance during the production of masonry work, excluding
