SORG melting technology
There are currently more than 250 SORG melting furnaces in operation throughout the world. Most of these are conventional gas or oil fired units with either regenerative or recuperative waste heat recovery. An increasing number are oxy-fuel melters, and a significant number are all-electric melters.
During the past 20 years we have also developed a range of specialist furnace concepts for particular applications. The LoNOx® Melter gives low NOx emissions, whilst the FlexMelter® is used for extreme flexibility and high glass quality and the Boro-Oxi-Melter® offers optimum melting conditions for hard borosilicate glass (α = 32 - 40 x 10-7).
We have designed and built furnaces for most commercially produced glasses, including:
Soda lime glass for containers, flaconage, pharmaceutical products, stemware, giftware, glass bricks,
lighting ware, tubing and rolled plate
Soft borosilicate C glass for insulating fibre
Borosilicate E glass for continuous textile fibre
Hard borosilicate glass (α = 32 – 40 x 10-7) for tubing, blown ware and kitchen ware
Neutral borosilicate glass (α = 48 – 60 x 10-7) for containers
Fluoride opal glass for lighting ware and containers
Stonewool for insulating fibre
Lead crystal glass for stemware and giftware
Ceramic frit for refractory and metal glazing
Additional systems such as boosters and bubblers are common features of our furnaces.
