Description

Изобретение относитс к литейному производству и может быть использовано в техиологии рафинировани металлов газами.The invention relates to foundry and can be used in the techiology of refining metals with gases.
Известны рафинирующие устройства, подвод щие инертный газ на дно тигл или плавильной печи посредством трубки с керамической диафрагмой различной конфигурацииRefining devices are known that supply an inert gas to the bottom of a crucible or a melting furnace by means of a tube with a ceramic diaphragm of various configurations.

Недостатком известного устройства вл етс то. что оно не обеспечивает равномерного распределени газа по всему объему металла из-за возможности прохождени газа через швы между трубкой и керамикой и в результате неравномерной пористости по всей поверхности керамики, а также из-за большого отклонени пористости по размерам, низкой стойкости керамики ж резкому перепаду температур .A disadvantage of the known device is that. that it does not ensure uniform distribution of gas throughout the metal because of the possibility of gas passing through the seams between the tube and ceramics and as a result of uneven porosity over the entire surface of ceramics, as well as due to a large deviation of porosity in size, low resistance of ceramics and a sharp drop temperatures.
Целью изобретени вл етс повышение степени рафинировани .The aim of the invention is to increase the degree of refining.
Это достигаетс тем, что диафрагма выполнена из пористого титана.This is achieved in that the diaphragm is made of porous titanium.
На чертеже представлено устройство дл рафинировани жидкого металла газами.The drawing shows a device for refining a liquid metal with gases.
Устройство состоит из емкости 1 дл жидкого металла, трубки 2 дл подвода газа, пористой титановой диафрагмы 3, распределител 4 газа.The device consists of a container 1 for a liquid metal, a tube 2 for supplying gas, a porous titanium diaphragm 3, and a distributor 4 of gas.
Дл повышени газопоглотительной способности и во избел ание заполнени лор металлом перед работой титанова диафрагма протравливаетс раствором щелочи.To increase the gas absorption capacity and in order to bite the metal entrapment before working, the titanium diaphragm is etched with an alkali solution.
Использование предлагаемого уст1ройства дл рафинировани сплавов дает возможность повысить степень рафпнировапи , что особенно при .получении стабильных высоких свойств отливок, и снизить брак по пористости iB готовых издели х.The use of the proposed device for refining alloys makes it possible to increase the degree of refining, which is especially when obtaining stable high properties of castings, and to reduce the defect on the porosity of iB finished products.
