Monometer was approached by West Country Tiling to comment upon and try to resolve reoccurring failures in their furnace crucible, and a variable melting performance. The furnace in question was a 1-tonne lead capacity crucible supplied by another company. A very interesting and complimentary video was also included from the client showing their production and manufacture of lead-roof sheeting. http://www.youtube.com/watch?v=YxywudfRvTE Monometer assessed the furnace design including burner system, together with the process requirements. Following investigation, several problem areas were identified including:
Furnace modifications were therefore advised as follows:
All recommendations were implemented by the client, and ultimately the melt time was considerably reduced, fuel efficiency increased in proportion to the reduced melt cycle time and following a reduced normal firing rate, and issues concerning crucible longevity and reliability were entirely eliminated. Attractive economy of the work required to implement the proposed solutions was achieved by the client carrying out fabrication work locally and since the majority of the existing burner fabrication was reused and constituent parts retained. Additionally, Monometer was able to supply a competitively priced made-to-measure bottom-pouring cast iron crucible. After the furnace modifications at West Country Tiling had been completed, and the new pot had been fitted, Toby Pitt commented “Despite my unnecessary worrying the outcome is perfect. Thank you”. Monometer welcomes enquires for new furnace equipment as well as for assisting with updating or problem-solving performance issues whether process or furnace related. |
