Foil bag, carbon containing nipple, nipple kit, carbon containing electrode, electrode kit, electrode-nipple system, furnace and method of operating the furnace

A method for producing an electrode/nipple system comprising the steps of:

• providing a nipple kit, containing:
• at least one carbon-containing nipple for carbon-containing electrodes, the carbon-containing nipple having at least one nipple thread with at least one inlet formed therein being a groove running across the nipple thread in a substantially perpendicular direction to the nipple thread, the carbon-containing nipple being a cylindrical double-thread nipple or a double-conical double-thread nipple;
• and
• at least one adhesive container disposed in the inlet, the adhesive container containing a liquid or pasty thermally and/or chemically curing adhesive for securing of an electrode/nipple connection,
• the adhesive container having at least one of at least one weakening area or at least one weakening line extending from one end of the adhesive container to an opposite end of the adhesive container and/or formed on a same side of the adhesive container;
• providing a carbon-containing electrode having a socket thread;
• screwing the at least one carbon-containing nipple into the socket thread of the carbon-containing electrode, the screwing step resulting in a destruction of the least one adhesive container thus releasing the liquid or pasty thermally and/or chemically curing adhesive;
• distributing a released adhesive during the screwing step over a surface that is larger than a surface covered by the inlet between the nipple thread and the socket thread;
• and
• hardening the released adhesive at a given temperature in a range between room temperature and up to 250° C. over a time period of at least five minutes.
