(54) ФУРМА ДЛЯ ПРОДУВКИ РАСПЛАВА(54) MILLING TURMET
1one
Изобретение относитс к цветной металлургии и предназначено дл использовани при продувке расплавов в пирометаллургических агрегатах.The invention relates to non-ferrous metallurgy and is intended for use in purging melts in pyrometallurgical aggregates.
Известна фурма дл продувки расплава , включающа охлаждаемый корпус с фурменным каналом и фурмовочный клапан 1.A known lance for purging the melt, comprising a cooled housing with a tuyere channel and a tuyere valve 1.
Недостатком известной фурмы вл етс то, что при падении давлени или прекращении подачи поступающего газа (воздуха или кислорода) происходит аварийна заливка фурменного канала расплавом.A disadvantage of the known tuyere is that when the pressure drops or the supply of incoming gas (air or oxygen) is stopped, an emergency melt feed of the tuyere channel occurs.
Цель изобретени - предотвращение аварийной заливки расплавом фурменного канала.The purpose of the invention is to prevent the emergency melt pouring of the tuyere channel.
Поставленна цель достигаетс тем, что фурма, включающа корпус с фурменным каналом и фурмовочный клапан , снабжена расположенным над фурменным каналом карманоп с шариком из огнеупорного материала, стопором дл шарика, сильфонньтм устройством.This goal is achieved by the fact that the lance, comprising a housing with a tuyere channel and a tuyere valve, is provided with a pocket above the tuyere channel with a ball of refractory material, a stopper for the ball, and a bellows device.
св занным со стопором и фиксатором, .установленным в устье фурменного канала .connected to the stopper and the locking mechanism installed at the mouth of the tuyere channel.
На чертеже показана фурма, разрез.The drawing shows a lance, section.
Фурма включает охлаждаемый корпус 1, фурменный канал 2, фурмовочный клапан 3, карман 4, крышку 5, шарик 6 из огнеупорного материала, стопор 7, сильфонное устройство 8 и фиксатор 9.The lance includes a cooled body 1, a lance channel 2, a lance valve 3, a pocket 4, a lid 5, a ball 6 of refractory material, a stopper 7, a bellows device 8 and a latch 9.

Карман 4 расположен над фурменным каналом 2. В кармане 4 помещаетс шарик 6 из огнеупорного материала, который удерживаетс в нем с помощью стопора 7, св занного с сильфонным Pocket 4 is located above the tuyere channel 2. In pocket 4, a ball 6 of refractory material is placed, which is held therein by means of a stopper 7 connected to the bellows.
IS устройством 8.IS device 8.
В фурменном канале 2 установлен фиксатор 9, служащий дл удержани в устье фурменного канала 2 шарика 6 из огнеупорного материала, посту20 пающего в момент возникновени аварийной ситуации.In the tuyere channel 2, a clamp 9 is installed, which serves to hold in the mouth of the tuyere channel 2 a ball 6 of refractory material that is supplied at the time of the occurrence of an emergency.
Работа фурмы осуществл етс следующим образом.The operation of the tuyere is carried out as follows.
