Description

Известные способы ведени  мартеновской плавки на высококалорийном газе с применением сжатого воздуха или кислорода дл  организации факела мало эффективны, так как не обеспечивают достаточно высокой температуры факела и хорошей теплопередачи.The known methods of maintaining open-hearth smelting on high-calorific gas using compressed air or oxygen for organizing a torch are not very effective, since they do not provide a sufficiently high torch temperature and good heat transfer.

Дл  устранени  указанных недостатков , а дл  снижени  расхода топлива предлагаетс , согласно изобретению, высококалорийный газ низкого давлени  перед подачей в головку печи предварительно нагревать в регенераторах, или рекуператорах .To eliminate these drawbacks, and to reduce fuel consumption, according to the invention, a high-calorific low-pressure gas is proposed to be preheated in regenerators or recuperators before being fed into the furnace head.

Нагрев газа предлагаетс  вести до температуры, обеспечивающей, с одной стороны, светимость факела и, с другой стороны, отсутствие выпадени  сажистого углерода в насадках регенераторов.Heating of the gas is suggested to be maintained to a temperature that, on the one hand, ensures the luminosity of the plume and, on the other hand, the absence of carbon black deposition in the nozzles of the regenerators.

Предлагаемый способ заключаетс  в использовании на существующих мартеновских печах или на печах иной конструкции одного высококалорийного газа (коксовального или природного) низкого давлени .The proposed method consists in using a single high-calorific gas (coking or natural) of low pressure on existing open-hearth furnaces or on other furnaces.

подогреваемого до температуры автокарбюрации в регенераторах или рекуператорах.heated to temperature autocarburers in regenerators or recuperators.

Факел такого газа организуетс  за счет кинематической энергии воздушной или кислородной струи, подаваемой дл  организации и интенсификации факела.The torch of such a gas is organized by the kinematic energy of an air or oxygen jet supplied to organize and intensify the torch.

Дл  промышленного использовани  предлагаемого способа необходимо на существующих мартеновских печах, работающих на смешанном газе, уменьщить сечение газовых пролетов с тем, чтобы снизить на 70-80- количество продуктов горени , пропускаемых по газовому тракту. Уменьщение продуктов горени  позвол ет предотвратить перегрев газовых насадок выше 1350 что приводит к потере светимости факела.For the industrial use of the proposed method, it is necessary to reduce the cross section of the gas spans in existing open-hearth furnaces operating on mixed gas in order to reduce by 70-80 the number of combustion products passed through the gas path. Reducing the combustion products helps to prevent overheating of gas nozzles above 1350, which leads to a loss of luminosity of the torch.

Дл  уменьшени  перерыва в подаче газа в период кантовки следует на период перекидки подавать доменный газ. Подача доменного газа должна при этом осуществл тьс  автоматически.To reduce the interruption in the gas supply during the period of turn-over, blast-furnace gas should be supplied for the period of transfer. The supply of blast furnace gas must be automatic.
