Product introduction:

The electric furnace series mainly includes arc furnace transformer, ladle refining furnace transformer, electric slag furnace transformer, ore heat furnace (ferroalloy furnace, calcium carbide furnace, yellow phosphorus furnace, etc.) transformer, power frequency induction furnace transformer and other AC furnace transformers. Electric furnace transformer refers to the power transformer for industrial electric furnace smelting. It is a special transformer designed according to the load characteristics and operation characteristics of various electric furnaces.

Process and characteristics:

The iron core is made of high-quality cold-rolled oriented silicon steel sheet, and is sheared and formed by longitudinal shearing line and transverse shearing line. The shearing burr is small, and the iron core stacking adopts full oblique seam multi-stage stepping process, which effectively ensures the low no-load loss, no-load current and noise of the product.

The coil is wound with high-purity semi-hard oxygen-free copper paper wrapped flat wire, and the turn insulation is made of high-quality insulating paperboard, which effectively improves the coil's ability to resist sudden short circuits. The inner coil is directly wound on the insulating cylinder, and all coils use inner and outer stays. All stays and pads are chamfered, the electric field is uniform, and the reliability is enhanced. The coil assembly adopts a synchronous lifting system, which effectively controls the axial size of the coil, ensures the axial clamping force of the coil, and effectively reduces the wire loss.

The oil tank adopts a folded plate flat-top oil tank, and the box wall adopts a wide steel plate, which reduces the welds, makes the transformer beautiful and simple as a whole, and improves the mechanical strength. The oil tank can withstand the mechanical strength test of positive pressure and vacuum specified in the standard.

Low loss, low noise, low temperature rise, high reliability, no hanging core, no leakage.

Electric furnace transformers are mainly used for steelmaking, copper smelting, production of calcium carbide, ferroalloys, siliconized special, melting pig iron, etc.
