Abstract: Группа изобретений относится к способу получения сплавов, в частности к способу плавки с расходуемым электродом. По способу формования деформируемого продукта из исходного металла, такого, как тантал, ниобий или их сплавы, расходуемый электрод покрывают по меньшей мере одним слоем сплава с помощью средства, обеспечивающего его равномерную толщину. К телу электрода подводят мощность, достаточную для дугообразования, заставляющего плавиться исходный металл и слой сплава с образованием ванны расплавленного металла в тигле. Равномерный слой на теле электрода представляет собой средство подачи минимальных количеств сплава в большее количество исходного металла и облегчает равномерное и надлежащее дугообразование, которое способствует перемешиванию сплава и исходного материала в тигле. Тело электрода расходуется с повышенной скоростью без связанного с этим уменьшения выхода годной продукции по окончательному весу слитка. Расплавленному металлу дают затвердеть с образованием слитка. После этого слиток перерабатывают в деформируемый продукт. Желаемый технический результат - равномерное распределение желаемого количества сплава в большом количестве исходного металла одновременно с расплавом тела расходуемого электрода, создание гладкой дугообразующей поверхности электрода, на которой нет выступов и которая минимизирует дугообразование в направлении боковых стенок тигля. Кроме того, группа изобретений позволяет разработать средство перемешивания расплавленного сплава с расплавленным исходным материалом без внесения загрязнений из тигля в ванну расплава металла. 5 с. и 19 з.п.ф-лы, 12 ил.

Granted: 1998-11-10
Abstract: FIELD: electrical engineering. SUBSTANCE: capacitive transducer is formed by pointer indicator and immovable electrodes made of current-conducting material applied on scale. Electrodes are insulated electrically from both scale and remaining members of instrument construction. System of immovable electrodes is essentially one or several concentric arc- shaped layers with center on pointer rotational axle. Layers are separated from one another by grooves. Every layer is divided by radial grooves oriented relative to scale marks into several sectors combined electrically into two electrodes so that adjacent sectors of layer refer to different electrodes. Every electrode of every layer is connected to separate auxiliary terminal. Pointer position on scale is determined by means of capacitive transducer. Its output parameters indicate layer electrodes above which pointer is located. Since radial grooves separating the electrodes are oriented relative to scale marks, position of pointer on scale may be determined. Due to differential structure of variation of every layer output capacitances, use may be made of highly sensitive bridge circuits for their conversion. EFFECT: enhanced measurement accuracy. 4 dwg
