SU59706A1 - Seal for arc furnace electrode - Google Patents

Description

In closed-type electric furnaces, electrodes are usually passed through openings specially made in the arches of the furnace. In those cases, when the gases formed in the electric furnace are the main product of the product: Vodstva, the loss of them through the rings of Zazo-p leads to a decrease in the productivity of the furnace units. In addition, the breakthrough of gases through the face gap makes it extremely difficult to maintain the furnace at the junction points of the electrodes, where electrode holders and all current carrying choi are usually concentrated. When it is necessary to bear in mind that in many industries, gases produced by the process of production are all made, explosive, etc.

Various designs have been proposed repeatedly to create a gas & permeable seal between the roof of the furnace and the electrode.

In particular, it was proposed to use seals around the electrodes in the form of an ovale with a different pack (powdered graphite with asbestos, various resins, etc.).

The proposed seal is also made in the form of an omentum containing liquid resins, pitches, etc., located in the gap between the electrode and the electrode, which electr01D with an annular cooler.

It differs from the known seals in that here, in order to efficiently use this kind of saline in furnaces with a temperature of about 500 (for example, in furnaces for the sublimation of phosphorus), a mixture of resins, tar and mineral lubricants with high flash point and asbestos cotton or graphite taps, the cooler is designed so that the mixture from the side of the cooler, due to intensive cooling, is in the solid state, and from the electrode in the liquid, which creates be slidably electrode through the seal.

The enclosed drawing shows the proposed seal structure in two projections.

The seal consists of a water-cooled hollow ring 1, which on the inner side is bounded by a truncated cone, which passes on the side facing the bottom of the furnace into a cylindrical section. The ring is mounted on a special, square shape, pipe 2, the transition is clicked on the side.

With a continuous power supply of the furnace, such a dissolution of the leakage allows you to keep the high level of the furnace in the furnace, thus preventing the heating I from ring I, on the one hand, and improving the operating coefficient of the heating system, on the other side. In the formed ccthium space, a cross section between the electrodes and the ring 1 is filled with a rasplet,: iopec, displaced from the asbestos wat: 1Y.
