Continuous furnace electrode adjustment - by programmer controlling release valve for brake ring adjustment cylinders

摘要

A continuous adjustment system for the electrode of an electric furnace which is raised and lowered by hydraulic cylinders includes a calibrated restrictor valve which is connected to a programmer and meters the return rate of the hydraulic fluid from the hydraulic adjustment cylinders. It is fitted between these cylinders and the spool valve for the pressure and return line of the hydraulic fluid. This saves 3 - 4 m in the height of the furnace bay building, compared with Wisdom or Tagliaferri systems. The adjustment operation can be fully automated. The new system can be added to existing installations. It ensures better carbonisation conditions for self-sintering electrodes. USed in ferrous and non ferrous metallurgy and in the chemical industry.
