Common causes of refractory failure Engineer Live

Dissimilar refractory materials adjacently located are common particularly surrounding openings such as doors (fibre and brick) peep sights (IFB castable fibre modules) burner blocks and pressure relief doors. Because dissimilar materials have different refractory properties at elevated temperatures this makes a homogenous design difficult.

Refractory Selection Guide for Secondary Aluminium Smelting

Apr 28 2011 · Refractory Selection Guide for Secondary Aluminium Smelting. Secondary aluminium smelting differs from primary smelting in that it uses recycled aluminium from scrap rather than refining it from ore. Producing one ton of aluminium from scrap uses about 5 of the energy of that required to produce it from bauxite.

Controlling refractory erosion in induction furnaces the

Aug 01 1991 · Refractory melting in an induction furnace is abnormal but unfortunately not uncommon. It is not a normal erosion mechanism but rather is a consequence of buildup clogging or bridging. Entrapped metal in a high-energy induction field can easily reach the failure temperature (melting point) of the refractory material.
