Péter Bencze (66), original qualification: dipl. electrical engineer, currently technical consultant for F.I.C. (UK) limited.
He has been working in the glass industry for 42 years. In 1977, after graduating he started to work at the Nagykanizsa Glass Factory of the Hungarian Glass Works in the maintenance area. Two years later he got involved in a development project of implementing a cold-top all-electrically heated furnace for melting hard borosilicate glass.
This task basically determined his further professional career as in the following 26 years he was in charge for designing electrical electrode-boosters for fossil-fired furnaces for melting glasses of various types, and cold-top all-electric furnaces of 0.5 – 15 tpd melting capacity.
From 1984 he worked as chief technologist, from 1987 as chief engineer, and from 1990 as plant manager for 15 years.
The plant produced heat resistant laboratory and household glass products, thermo-bottle and thermo-jar inserts as well as ampoules and vials from neutral borosilicate glass tubing.
In addition to various managing tasks he was directly in control of the development of cold-top all-electric furnaces.
In his work, through connections with research institutes and in the well-equipped laboratory of the plant he had the opportunity to have the melting properties of various raw materials analyzed. Tests were made, among others, on how glass quality changes depending on the properties of the raw materials used for batch-making, on the surface load of the melter, flow of glass melt in various melter types subject to minimum and average residence time. A very motivating and professionally serious challenging project was melting neutral borosilicate glass in a cold-top all-electric furnace.
Since 2006 he has been working for F.I.C. and was involved in many interesting tasks including, but not limited to solving problems related to glass quality and operation, and the preparation of various projects.
As of January 01, 2014 company Glass Service in the Czech Republic has been the owner of F.I.C. This condition means considerable help in the work as precise theoretical explanations of technological details can be provided when practical experiences are supported by mathematical modeling.
“The presentation will examine the effect of the change in grain size distribution of sand on the quality of melting on an all-electric cold top and semi-hot top furnaces.
The presentation deals with the grain size distribution of silica and quartz sands normally used for fossil fired furnaces, a comparison of flow conditions in fossil fired and cold-top melters. The circumstances determining the minimum residence time in fossil fired and cold-top melters, melting problems caused by short minimum residence time and what possibilities are available to improve the quality of melting in the case of a cold top melter.
The presentation demonstrates by two examples, what improvement can be achieved by using sand of a technologically more favourable grain size distribution”.
