Description

Вследствие большего линейного удлинени  вставки при разогреве деталей достигаетс  плотное прилегание по всем соединени м контактного узла, что повышает надежность его в работе.Due to the greater linear elongation of the insert, when parts are heated, a tight fit is achieved over all connections of the contact unit, which increases its reliability in operation.

Формула изобретени  1. Неохлаждаемый контакт дл  присоединени  электрода к токоподводу дуговой электропечи по авт. св. № 460603, отличающийс   тем, что, с целью повышени  надежности работы,Claim 1. Uncooled contact for connecting the electrode to the current supply of an electric arc furnace according to ed. St. No. 460603, characterized in that, in order to increase the reliability of operation, он снабжен компенсационной вставкой, установленной между токоподводом и верхним концом электрода и выполненной из материала с коэффициентом линейного расширени  большим, чем у втулки.it is equipped with a compensation insert, installed between the current lead and the upper end of the electrode and made of a material with a linear expansion coefficient greater than that of the sleeve. 2. Контакт по п. 1, отличающийс  тем, что в нижней части вставки выполнена проточка нод электрод.2. A contact according to claim 1, characterized in that a notch electrode is formed in the lower part of the insert.
