Description

Известный способ обжига электроугольных изделий, загружаемых в печи в сосудах, например в термостойких тигл х,  щиках и т. п., предусматривает применение угольной засьшки.The known method of firing electric-coal products loaded into furnaces in vessels, for example, in heat-resistant crucibles, boxes, etc., involves the use of coal waste.

Особеннасть предлагаемого способа заключаетс  в осуществлении обжига без засыпки в закрытых сосудах, внутри которых восстановительна  среда образуетс  в результате выделени  летучих углеводородов из обжигаемых заготовок.The particularity of the proposed method lies in the implementation of roasting without backfilling in closed vessels, within which the reducing medium is formed as a result of the release of volatile hydrocarbons from the roasted blanks.

Применением закрытых сосудов и исключением засыпки обеспечиваетс  сокращение времени обжига, снижение брака продукции и улучшение санитарных, условий дл  обслуживающего персонала.By using closed vessels and eliminating backfilling, the burning time is reduced, product waste is reduced, and sanitary conditions for the staff are improved.

В качестве сосудов дл  загрузки изделий можно примен ть обычные luaMOTHbie или графитовые тигли с крыщками или же металлические сосуды (чугунные или стальные) в зависимости от типа и конструкции печи.Conventional luaMOTHbie or graphite crucibles with lids or metal vessels (cast-iron or steel) can be used as vessels for loading products, depending on the type and design of the furnace.

Дл  тоннельных печей целесообразно использовать сосуды в виде герметически закрытых металлических  щиков с р дом перекладин дл  укладки изделий.For tunnel kilns, it is advisable to use vessels in the form of hermetically sealed metal boxes with a series of crossbars for stacking products.

Загружаемые издели  необходимо располагать на некотором рассто нии от дна (примерно 50-70 мм). Дл  этого можно применить дополнительно дно с р дом отве|рстий или подставки.Downloadable products must be placed at some distance from the bottom (approximately 50-70 mm). For this, you can apply an additional bottom with a number of openings or stands.

Дл  удобства загрузки и выгрузки изделий можно использовать сосуды из тонкого железа (с отверсти ми), в которые помещаютс  издели . Эти сосуды затем вставл ютс  в сосуды, герметически закрываемые дл  проведени  обжига,For ease of loading and unloading products, thin iron vessels (with holes) can be used in which the products are placed. These vessels are then inserted into vessels hermetically sealed for calcining,

Дл  поглощени  газов, в отдельных случа х выдел ющихс  из со судов и угрожающих загр знению печи, могут примен тьс  адсорбентьГ. Адсорбенты могут располагатьс  в специальных приспособлени х над крышкой закрытого сосуда.Gel adsorbent may be used to absorb gases that, in some cases, are released from ships and threaten to contaminate the furnace. Adsorbents can be placed in special devices above the lid of a closed vessel.

Предмет изобретени Subject invention

Способ обжига электроугольных изделий, загружаемых в печи в-сосудах , например в термостойких тигл х,  щиках и т. п., отличающийс  тем, что, с целью сокращени  времени обжига, снижени  брака продукции и улучщени  санитарных условий дл  обслуживающего персонала, обжиг осуществл ют в закрытых сосудах без засыпки в газовой восстановительной среде, образуемой внутри сосуда в результате выделени  летучих углеводородов из обжигаемых заготовок.The method of firing electric-coal products loaded in furnaces in vessels, e.g., heat-resistant crucibles, boxes, etc., characterized in that, in order to reduce the firing time, reduce production waste and improve sanitary conditions for the staff, firing is performed in closed vessels without backfilling in a gaseous reducing medium formed inside the vessel as a result of the release of volatile hydrocarbons from the baked blanks.
