Metal Production

SOL designs, manufactures and offers its customers different kinds of burners for oxy-combustion from a few hundred kilowatts to more than 3 MW, specific for the various usage sectors and adaptable to different melting plants and the differing process and application needs and requirements. These are sold under the SOLMET trademark and can work with all kinds of fuel (methane, GPL, oil…).

For the production of cast-iron in rotary kilns, SOL produces burners with watercooled sleeves, fitted with specific nozzles specially designed to produce suitable flame fluid dynamics and fast and uniform heating of the content of each rotary kiln. They can also be used to preheat ladles with clear and demonstrated benefits in terms of shorter heating times and fewer defects in the castings thanks to the greater fluidity of the molten metal.

For the aluminium sector, specific burners for fixed or tilting axis rotary kilns with single or double passage are available that can work in difficult conditions such as processes and salt, re-melting of process waste, the melting of contaminated and low quality scrap.

For reverberatory melting furnaces with single or double chambers, the offer ranges from burners that can be installed in the crown, on the wall or in special fume recirculation ducts that help to obtain high productivity and yield while limiting fuel consumption and losses through oxidation. Special burners make it possible to use a dynamic flame that ensures high thermal efficiency and effectively reduces the formation of local overheating which tends to produce dross and reduce productivity.

Among the principal models available for wall installation, usable also in the glass sector, “flat” flame burners can produce a broad flame that heats the surface of the bath energetically but uniformly.

For forges and rolling mills, regenerative and self-recuperative SOLmet burners can operate in oxy-combustion or only in oxygen enrichment, guaranteeing rapid and uniform heating and significant fuel savings.

Numerical and thermo fluid dynamic (CFD) modelling carried out in collaboration with the principal research and university centres is used to verify the applications proposed in the design phase.
