Description
Существующа промыщленна практика обжига анодов и подин алюминиевых электролизеров, заключающа с в том, что обжиг производитс только после окончани всех монтажных работ серии (82) электролизеров, имеет следующие недостатки: обжиг производитс дорогосто щим посто нным током; разрыв во времени между готовностью электролизеров к обжигу и готовностью преобразовательной подстанцип длитс иногда несколько мес цев; одновременное включение на обжиг всей серии электролизеров или отдельными ее группами в 2-3 очереди св зано с болыпим объемом работ но временной ощиновке и нереключс-ни м схемы ошиновки дл постепенного подъема силы тока и приводиi к сильной загазованности электролизного цеха возгонами пека, что создает т желые услови труда дл обслуживающего персонала и затрудн ет качественное ведение процесса обжига.The existing industrial practice of burning anodes and bottom aluminum electrolysis cells, which means that the firing is performed only after all the installation work on the series (82) of the electrolysis cells is completed, has the following disadvantages: firing is performed by expensive direct current; the gap in time between the readiness of the electrolyzers for firing and the readiness of the converter substation lasts sometimes for several months; simultaneous switching on the roasting of the entire series of electrolyzers or its individual groups in 2–3 queues is associated with a large amount of temporary work and non-switching of the busbar circuit to gradually increase the amperage and lead to a strong gas content of the electrolysis plant with subkeys of pitch, which creates The desired working conditions for the service personnel make it difficult to maintain the firing process.
Описываемый способ исключает эти недостатки, так как обжиг анодов и нодин алюминиевых электролизеров производитс постепенно в процессе монтажа при помощи форсунок, работаюнпх на жидком или на природном газе.The described method eliminates these drawbacks, since the firing of the anodes and the nodes of the aluminum electrolysis cells is carried out gradually during the installation process with the help of nozzles working on liquid or natural gas.
На фиг. 1 приведена схема обжига анода и набивных швов подины алю.миниевого электролизера в поперечном разрезе; на фиг. 2 - то же, зид сбоку.FIG. 1 shows a diagram of the firing of the anode and stuffed seams of the bottom of the aluminum-aluminum electrolyzer in cross section; in fig. 2 - the same, side view.
Сущность способа заключаетс в том, что в период монтажа электролизеров , после окончани футеровки подины и набивки щвов углеродистой массой, подину ванны выстилают слоем / листового асбеста толщиной 10 мм и укрывают слоем 2 огнеупорного кирпича толщиной 65 мм всухую, без раствора. Затем на кирннчные тумбы 3 сечением 250X250 .i;.u и высотой 500 мм кладут донный стальной лист 4 анода, на который устанавливают анодный кожух 5 и загружают анодную массу 6. В анода под донньп- лист устанавливают но одной форсунке 7 и пачиtaiOT обжиг, который продолжаетс в течение щести суток, после чего элПчтролизер готов дл промыщленной эксплуатации. Общий расход ди::ел1 )ного топлива на один электролизер составл ет 6 г.The essence of the method lies in the fact that during the installation of the electrolyzers, after the lining of the bottom and the jaws are filled with carbonaceous mass, the bottom of the bath is lined with a layer / sheet of asbestos 10 mm thick and covered with a layer 2 of 65 mm refractory brick dry, without mortar. Then, the bottom steel sheet 4 of the anode, on which the anode casing 5 is installed, is placed on the crown pedestals 3 with a section of 250X250 .i; .u and a height of 500 mm, and the anode mass 6 is loaded into the anode but one nozzle 7 and a pactiiOT roasting are installed which lasts for a day, after which the elPhtrolizer is ready for industrial operation. The total consumption of di :: el fuel for one cell is 6 g.
