Detailed Product Description
Electroslag remelting furnace (ESR furnace) provides optimal removal of sulphur, non-metallic inclusions and gases.

ESR furnace/electroslag remelting furnace is a current production of heat using molten slag into the pool from the power level, the metal droplet liquid washing through the residue, after crystallization in water-cooled crystallizer Into the ESR of special refining equipment. As the slag to the mixture of liquid crystal effects and good conditions for ESR metal with good Purity, cast structure is uniform, no white spots and the ring-like segregation, very low sulfur content, inclusion of small dispersion and other fine performance.

Therefore, ESR in the medium-sized forgings, rough blocks the production of a monopoly position in the high-quality tool and die steel, duplex steel billet, cold Rolling
Electroslag furnace is particularly Special steel production equipment is essential. ASMITA ENGINEERING electroslag furnace company making full use of the most mature technology design, manufacturing production stereotypes Products.

Metallurgy of the Electroslag Remelting Process

Due to the superheated slag that is continuously in touch with the electrode tip, a liquid film of metal forms at the electrode tip. As the developing droplets pass through the slag, the metal is cleaned of non-metallic impurities which are removed by chemical reaction with the slag or by physical flotation to the top of the molten pool. The remaining inclusions in ESR are very small in size and evenly distributed in the remelted ingot

* Its melting point must be lower than that of the metal to be remelted;
* It must be electrically efficient;
* Its composition should be selected to ensure the desired chemical reactions;
* It must have suitable viscosity at remelting temperature.

The ingot surface covered by a thin slag skin needs no conditioning prior to forging. Electrodes for remelting can be used in the as-cast condition.

Electroslag Remelting Furnaces

Significant advances have been made over the years in plant design, coaxial current feeding and particularly in computer control and regulation with the objective of achieving a fully-automatic remelting process. This in turn has resulted in improved metallurgical properties of the products. A fully coaxial furnace design is required for remelting of segregation-sensitive alloys in order to prevent melt stirring by stray magnetic fields.

Shielding of the melt space with protective atmosphere has been the latest trend in recent years. Remelting under increased pressure to increase the nitrogen content in the ingot is another variation of ESR. ESR furnaces can be designed for remelting of round, square and rectangular (slab) ingots.

* Homogeneous, sound and directionally solidified structure;
* High degree of cleanliness;
* Free of internal flaws (e.g. hydrogen flakes);
* Free of macro-segregation;
* Smooth ingot surface resulting in a high ingot yield.
