Project and Design of the Porcelain Enamelled Steel Composites

by Silvano Pagliuca - I.E.I. Secretary General
The knowledge of mechanical and thermal properties of enamelling grade steel and of porcelain (vitreous) Enamels and the Stress-Strain analysis of vitreous-steel composite are the pillars for a correct designing of enamelled parts.
Robustness of enamelled product throughout its in-use life requires that the design of the enamelled parts are developed according to specific rules and links aiming at reducing the stress / strain in the composites.
The presentation “Project and Design of the Porcelain Enamelled Steel Composites“ was prepared by Silvano Pagliuca, I.E.I. Secretary General as a lesson to Italian Enamellers on behalf of C.I.S.P. - Centro Italiano Smalti Porcellanati and for disseminating porcelain enamel technical information to Italian students of Milano and Faenza Universities.
This presentation could be available in power point version for all I.E.I.’s Affiliates Enamellers Associations upon request, if interested to disseminate this kind of technical information among their members in occasion of their national Congresses and technical trainings. The I.E.I.’ Secretary General, Silvano Pagliuca could be available to give the lesson, as well.

Enamels applied to steel have characteristics similar to bi-metallic strips. The stresses that are induced during the firing have a very practical value and can be beneficial to the after fired strength of the enamelled article. Understanding the limitations of the strains and stresses in enamels will aid in controlling the movement of parts that are exposed to high temperatures such as ovens and range tops.

The question most often asked of porcelain enamel technical personnel is, "What can be done to reduce chipping, minimize crazing, lower warping, and eliminate spalling on enamelled parts processed in various segments of the industry?"
