MONOMETER at GIFA

Monometer’s first appearance at the GIFA Foundry Show was in 1974.  The success of this event for Monometer led to the Company exhibiting at subsequent GIFA shows which are held every 4 or 5 years, all of which were partly sponsored by the UK government. 

GIFA 2011 saw a small decrease in the number of exhibitors from 793 to 723, although there is a total increase on space booked to 42,000 square meters. 

There was an extensive programme of events, seminars and trade symposia.  In addition there was an exchange of ideas and information at the “GIFA-Treff” and the World Foundry Organization Technical Forum. 
 
Monometer rotary furnaces for the reclamation of tin and lead, have been in particularly high demand, following a significant rise in commodity prices over the past few years.  In particular for tin dross processing, for which up to 99.5% of the metal-bearing material in a charge can be recovered as recycled tin. The smelting process is attractively simple and does not involve salt, so the environmental impact of final waste products is low and will typically pass for low cost disposal routes.
 
Monometer rotary furnaces are made in the UK to the highest standards of machining and fabrication to ensure reliable alignment of all drive train and furnace rotating components; and all welding, including the integration of spun dished ends, is checked to ASME and/or ISO certification. Following these standards furnace quality is guaranteed, and indeed proven by the many installations worldwide now having achieved in excess of 25 years continuous operation.
 

The Monometer smelting system extends to accommodate ores of lead, copper and tin, and has been applied in the reclamation of silver from charges of various mixed material. In each of these applications the unique bath depth and rotational programme retain metal fume within the reactive bed of the furnace chamber and effect a rapid cycle and high yield; recoveries of up to 99.5% are quoted in all offers where exhaust dusts are returned to the furnace and this performance is guaranteed subject only to a certified charge assay.
 
 
Both low NOx air-fuel and oxy-fuel burner technology are offered with Monometer deep bath smelting furnaces. This is in consideration for the varying needs of diverse processes and client circumstances. In particular, the attractions of the oxygen burner can include a lowering of emissions volumes by up to 75% with an accompanying reduction in the required size of filtration plant, cycle time reduction by up to 40% and reduced metal losses. However, these attractions are attainable for many, but not all processes. For example, a smaller and therefore less costly filtration plant requirement, (which can offset higher oxy-fuel capital costs), is typically only realised where emission volume is reduced by at least 50%, and cycle time is not always influenced significantly by flame temperature alone. This is why Monometer air-fuel systems, having been developed to maximise the heat recovery attainable from vortex recirculation (double pass) principles, remain a highly attractive option for all processes, particularly for tin and lead smelting, and are effective and economical in situations where the necessary oxygen supply is not always available locally at the site of installation.
