It introduces the successful experience of gas and hydraulic pressure spring pressure maintaining load screw- down electrode holder applied to 16.

It introduced the structure and status of the electrode holder on submerged-arc furnace by the numbers in China.

The situation and effect of applying electrode holder without ring co llector to semiclosed ferroalloy electric furnace with low hood are introduced, its advantages and spread value are also affirmed.

Analysis and improvement of electrode clamper structure of baosteel group;

Aiming to the problems which are existed in the electrode holder at submerged arc furnace in China, such as, the asymmetrical pressure, the unsuitable control of the holder' s reduction and also the bad effect of the cooling water, we put forward the new ideas for designing new pressure ring holder.

Research construction design and parameters choice of the electrode holder,basing on the the key calculation on big and small water-cooling cashing pipe and pressure ring.

Submerged-arc furnace is a kind of primary equipment for ferroalloy smelting, and the electrode holder system is used for transferring powerful electric current to the electrode, clamping the contact shoe to the electrode, controlling the sintering of electrode.

An oblique hole through the glass pipette holder (above the lateral hole for cell seal suction) is drilled, through which a microcatheter (O.
