Our products

Product category: Regenerative systems


Regenerators packings are truly the lungs of the glass furnace. They decisively influence furnace performance and the quality of the glass produced.

Since 1973, SEFPRO has developed successive generations of innovative electrofused solution using the CRUCIFORMS® product range which enable each glassmaker to design their own personalised regenerator packing for every type of glass.
CRUCIFORMS® checker performance actively participates in lowering production cost:

  • Thermal efficiency results in both fuel savings and lower fume volume
  • The good resistance to physico-chemical attacks assures stable operating conditions and high quality glass. Therefore glassmakers can maintain regular production
  • Sustained thermal characteristics over time reinforce fuel savings and also facilitate a rapid return to previous fuel setting after changes in glass colour, composition or pull rates
  • High resistance to corrosion avoids intermediate repairs
  • Reduced risk of plugging enhances performance stability and lowers maintenance
In addition to supplying the features described above, CRUCIFORMS® product regenerator ensures rapid and reliable assembly.

The term Fused Cast refers to a manufacturing process in which the ceramic bonding is obtained by the solidification of a mixture which has been melted in an electric furnace and cast in liquid state into molds.

SEFPRO places particular emphasis on three fundamental properties of fused cast products which affect their use:

  • Oxidation level of the melted liquid: The oxidation level strongly influences compactness, blistering tendency, exudation, stoning and corrosion resistance. The optimal oxidation level depends on the melting process and proper control of the melting parameters within the furnace.
  • Compactness, cohesion and homogeneity of the crystallographic structure: The level of oxidation-reduction in the cast liquid and the solidification conditions strongly influence the quality of the crystaline structure and the compactness of fused cast products. These determine product behavior during utilization.
  • Size and position of the shrinkage cavities: In order to provide the best possible quality in terms of product end-use, the material contraction which occur during the solidification process must be carefully controlled, as it affects the homogeneity of the piece, the volume and location of the shrinkage cavity, and the residual stress.

The term of Sintered refers to a wide range of products in which the ceramic bonding is generally obtained by firing at high temperature. Occasionally a few products have only a hydraulic bonding and therefore the ceramic bonding is obtained in situ at working temperature.

SEFPRO provides high quality level sintered products specifically dedicated to the construction and equipment of glass furnaces. Several manufacturing processes are currently used:

  • Mechanical press process for the production of standard shapes in large quantities
  • Vibrocasting process, mainly utilized for the production of expendables for glass manufacturing
  • Isopress process well adapted for the production of high value special shapes for dedicated applications.
