The mast arms holding the electrodes can either carry heavy busbars (which may be hollow water-cooled copper pipes carrying current to the electrode clamps) or be "hot arms", where the whole arm carries the current, increasing efficiency. …

AC EAF from Primetals Technologies is the ideal melting unit for the production of all types of steel, from standard carbon grades to high-alloyed and stainless steel grades.

The EAF/LF Electrode Arms are widely used in steel-making electric arc furnaces, ladle refining furnaces, electro slag remelting furnaces, etc. its structure is a rectangular frame, the outer layer is a copper steel composite plate, and the outer surface of the copper plate is used to conduct electricity, and the inner part is cooled by water ...

Electrode arms for AC-EAF, DC-EAF and LF manufactured from copper/steel For Ø 100-800 mm sized electrodes · low operating costs · minimal shutdown times · easy handling · optimum symmetry · highest efficiency level

2014年7月23日 · Experiments were based on a modal analysis performed through several accelerometers distributed over the three main elements of the EAF structure (mast, arm, electrode) and excitation was given in two sets of tests by the hydraulic actuator and through the turning table system used to substitute the electrodes, respectively.

Metech STG vessel design, furnace gantry and roof lifting systems allow fast and easy operations, thus reducing maintenance times. The sturdy-type construction of the masts permits high regulating speeds; arms are designed with the smallest electrode pitch circle diameters, very important for arc radiation.

2016年6月27日 · Clamping systems can be mounted external to the mast arm or can be mounted inside the arm. Most are now mounted inside the arm as this provides protection for the mechanism. A spring mechanism ensures that the shoes contact the electrode and a mobile yoke holds the electrode in place.

Hydraulics design capacity with proprietary software. Finite elements calculations if required. We can fabricate based on own or third party’s designs. We offer tailor made solutions for problems in specific components. Plate cutter bed of 10’x 50’. Pipe, shapes (angle, canal, beams, circular and rectangular seccionans) and plate rollers.

This document summarizes key aspects of electric arc furnace (EAF) design and developments. It describes the basic construction of an EAF, including the furnace body, roof, electrodes, and electrical equipment.

Conductive arms are directly connected to the secondary of the EAF’s transformer by long and flexible cables. The arm and the electrode are supported by a mast, which is kept vertical by a set of guiding rolls (Figure 1). The mast includes a single-acting hydraulic cylinder, which allows the electrodes positioning.
