Description

Согласно изобретению внутренние стены вращающейс  печи облицовываютс  кремнистым материалом, например шлаком.According to the invention, the inner walls of the rotary kiln are lined with a siliceous material, such as slag.

Шлак дл  облицовки можно плавить во вращающейс  печи, мартеновской печи, или в какой-либо другой.Slag for cladding can be smelted in a rotary kiln, an open-hearth furnace, or some other.

Температура щлака, по выходе его из мартеновской печи, обычно близка к 1320-1370°С. Шлак выпускают в ковш, перенос т к вращающейс  печи и заливают внутрь ее. Температура шлака при выливании его во вращающиес  печи должны быть 1260-1320°С. Точка плавлени  щлака, в зависимости от его состава, колеблетс  в пределах от 1175 до 1230°С.The temperature of the slag, after it leaves the open-hearth furnace, is usually close to 1320-1370 ° C. The slag is released into a ladle, transferred to a rotary kiln and poured into it. The temperature of the slag when it is poured into a rotary kiln should be 1260-1320 ° C. The melting point of shlak, depending on its composition, ranges from 1175 to 1230 ° C.

Если вращающа с  печь, которую предполагаетс  облицовывать, относитс  к типу качающихс  печей, то ее можно слегка наклонить, чтобы облегчить заливку в нее расплавленного шлака. Желатель}10, чтобы печь вращалась во врем  заливки, а заливка шлака производилась со Скоростью около 6-7 т в минуту. Эта скорость  вл етс  наиболее подход щей дл  печи околО 8,5 м длиной и около 2,4 м диаметром . Шлак должен заливатьс  с такой скоростью, чтобы он не мог застыть и образовать твердую корку в том месте печи, где его заливают, раньще, чем он достигнет противоположного конца печи.If the rotary kiln, which is intended to be lined, is of the type of swinging kilns, it can be tilted slightly to facilitate pouring molten slag into it. Desire} 10, so that the furnace rotates during the pouring, and the slag is filled at a speed of about 6-7 tons per minute. This speed is most suitable for a furnace about 8.5 m long and about 2.4 m in diameter. The slag must be poured at such a rate that it cannot harden and form a hard crust in the place of the furnace where it is poured before it reaches the opposite end of the furnace.

После окончани  заливки щлака или немного раньше печь привод т в горизонтальное положение, если ее наклон ли. Печь вращают со скоростью, не превыщающей, по возможности, нормальной рабочей скорости , хот  вращение может быть и значительно более медленным.After the completion of potting or a little earlier, the furnace is brought to a horizontal position if it is tilted. The furnace is rotated at a rate not exceeding, if possible, the normal operating speed, although the rotation may be much slower.
