Description

II

Изобретение относитс к металлургии , а более конкретно к конструкци м устройств, предназначенных дл приема расплавленного металла из печи , транспортировки его к месту разливки и последующего выпуска.The invention relates to metallurgy, and more specifically to the design of devices designed to receive molten metal from a furnace, transport it to the place of pouring and subsequent release.

оabout

Наиболее близок к предлагаемому сталеразливочный чайниковый ковш, состо щий из металлического кожуха и футеровки, в которой имеетс два канала, сообщающихс с полостью ковша и сливным носком, в котором эти каналы сход тс друг с другом 1.Closest to the proposed teeming ladle, consisting of a metal casing and a lining, in which there are two channels connected to the bucket cavity and toe drain in which these channels converge with each other 1.

Недостаки известного устройства заключаютс в необходимости постепеннного наклона ковша по мере опорожнени последнего в течение всего .времени слива из него металла, а также в том, что при разливке весьма трудно получить ровную струю металла, что отрицательно сказываетс на качество слитка или отливки.The drawbacks of the known device are the need to gradually tilt the ladle as the latter is emptied during the entire time the metal is drained from it, and that it is very difficult to cast a smooth metal during casting, which negatively affects the quality of the ingot or casting.

Целью изобретени вл етс упрощение и повышение надежности процесг оа разливки.The aim of the invention is to simplify and improve the reliability of the casting process.

Поставленна цель достигатес тем, что в ковше, содержащем металлический кожух и футеровку, в которой выполнены два канала, сообщающиес с полостью ковша и сливным носком, каналы выполнены в виде сифона, в месте перегиба которого установлен аварийный клапан дл прекращени металла из ковша, а сливной носок размещен на днище ковша и сообщаетс с одним из каналов сифона.The goal is achieved by the fact that in the bucket containing a metal casing and lining, in which two channels are connected, communicating with the bucket cavity and drain toe, the channels are made in the form of a siphon, at the point of the bend of which an emergency valve is installed to stop the metal from the bucket and the drain The sock is located on the bottom of the bucket and communicates with one of the siphon channels.

Claims

The bucket consists of a metal casing 1, lined from the inside. In lining 2, a channel is made in the form of a siphon, one end 3 of which with a bucket cavity at its bottom, and the other end 4 of the siphon passes through lining 2 and the bottom of the bucket outside and ends with a replaceable drain toe 5- At the top of the siphon 6 (at the bend ) there is a valve 7 for depressurizing the siphon and for emergency termination of metal discharge from the ladle. The upper part of the bucket is made in such a way that the maximum level B of the metal in the bucket is below the upper part of the siphon 6 when the bucket is in the vertical position. When the bucket is tilted at a certain angle, the level of metal C in the bucket becomes higher than the top of the siphon 6. The bucket operates as follows. When the bucket is tilted at a certain angle, the level of the metal in the ladle becomes higher than the upper part of the siphon 6 and the molten metal, according to the principle of communicating vessels, fills a siphon in which when the metal part is lowered and the lower level of the siphon 6 is lowered, the pressure in siphon and on the surface of the molten metal in the ladle, i.e. The effect of the siphon and gave the metal a metal release occurs independently. When a situation is created (during the discharge of molten metal from the ladle), when it is necessary to immediately stop the discharge of metal, the upper part of the siphon is depressurized using the emergency valve 7, and the metal is drained from the ladle. is terminated. The implementation of the proposed bucket design will eliminate the need for a gradual tilting of the bucket during the entire time the metal is drained from it, as well as eliminating the possibility of independent departure of the molten metal from the bucket and thereby improving safety conditions when taking the molten metal from the furnace, transporting it to the site casting and subsequent release. Claims of the Invention A bucket for receiving, transporting and subsequently releasing molten metal, comprising a metal casing and a lining, in which two channels are made, communicating with the cavity of the bucket and the drain toe, in order to simplify and improve the reliability of the casting process, The channels are made in the form of a siphon, in the place of the inflection of which an emergency valve is installed to stop the release of metal from the ladle, and the drain sock is placed on the bottom of the ladle and communicates with one of the siphon channels.
