cold layer, arch temperature, glass melt temperature, and the electrical resistance of the melting area. But people are still vital. "In spite of considerable progress, melting of glass in an all-electric furnace is not possible without an operator," Mr Slezak says. Another leading Czech glassmaker, Preciosa, uses an electric furnace with
Since the day of our inception, we have been successfully trading and supplying our clients with Electric Melting Furnace. For wining the trust and confidence of our customers, we also carry out management, consultancy and engineering services for all these furnaces.
The J. stan~k, J. MatOj / Electric melting of glass 355 output of the power supply or the input to the furnace is usually controlled according to the temperature required in the furnace. Trier  pointed out that for the thermal stability of an electric furnace not only the electrical but also the thermal properties of glass melt are of major
Glass melting electrodes must withstand extremely high temperatures and aggressive glass melts. Molybdenum from Plansee is the right material for these challenging conditions.
LumaSense Technologies has developed a complete solution for monitoring the glass melt furnace. Improved monitoring of the glass temperature can help ensure product uniformity and improve efficiency by reducing cycle time by controlling the melting process.
It is shown quite generally that this maximum temperature, T-asterisk, must occur above the Kauzmann temperature and that the T-asterisk is such that T-asterisk is greater than T(m)/3, where T(m) is the melting temperature. Also, it is demonstrated tha T-asterisk may be considered to be approximately dependent upon two parameters: gamma, the
GF-25 Furnace / Glory Hole Combo. Perfect for the weekend warrior! Have glass to blow within the hour. The glory hole section is 12" x 15" deep and sits above the 25lb. crucible. It is made from a 2600° F (1,427° C) vacuum cast ceramic fiber tube. The crucible section is made of 3000° F (1650° C) insulating castable.
This technique is still extremely valuable in the analysis of hydrocarbon mixtures of high volatility and has become an important analytical tool in the petroleum industry. With the development of high-temperature columns the technique has been extended to mixtures of low volatility, such as gas oils and some residua.

Place silica dish or crucible into muffle furnace for about 15 minutes at 3500C. Remove after one hour and cool to room temperature, weight the crucible (W 1 ). Add enough sample into the crucible (0.5 – 2g) the quantity will depend on texture and source of sample) and weigh content (W 2 ).
Electric Metal Melting Furnaces - For casting, reclaiming, alloying, and refining gold, silver and other metals with similar or lesser melting temperatures. Equipped with electronic temperature controls with digital displays, these melters can reach a maximum temperature of 2010° F
pellets, flat glass, rolled plate, water glass and, of course, all types of containers. 4 GlasE/10.08/V2.2 SORG® has long been renowned for furnace development. This programme has led to significant improvements in conventional furnace technology and to the development of completely new furnace concepts. This brochure contains information

if the furnace temperature equals or exceeds the high limit set point of the controller The circuit breaker is used to turn the furnace on and off and also protects the electrical supply in the event that the furnace draws too much electrical current. The pilot light indicates that the circuit breaker is ON and
This range of furnaces offers several advantages and is suitable for firing and sintering of advanced ceramics and high temperature glass melting. Excellent temperature uniformity is obtained by the inclusion of molybdenum disilicide heating elements which are positioned around the walls of the chamber ensuring uniform heating of the sample.
Furnace Systems Technology Workshop Monday, March 13 through Wednesday, March 15 Register to attend this workshop designed for cast house managers, melt shop operators and engineers, and furnace operations personnel responsible for operating, specifying and purchasing melting and process heating equipment.
