Due to the typical recessed furnace shafts only a low crane hook height is required. The vertical treatment of long components minimizes changes of dimensions and shapes. A high heating and cooling rate with a uniform heat transfer to the components is achieved by a convection using circulation and a gas cylinder. <br><br>\nAlso different models of tower type melting furnaces with holding capacities from 600 to 5,000 kg and melting capacities from 300 up to 3,000 kg.\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Cuptoare cu ax Uterna offers an extensive range of shaft furnaces.
