CERAL SHAPES & JOINING AIDS
The lining of metal transfer & metal handling systems, for aluminium and alloys
  • Foundry Ceramic Shapes

Product

It is a range of products made by the high alumino-silicate fibers &/or high alumina cement (asbestos free) in standard and non standard shapes like tundish, launders, distribution pans, spouts, troughs, transfer ladles etc.
Joining aids consist of  CERAL MASTIC's   &   CERAL CEMENT.

Function

CERAL SHAPES are having following advantages over other refractory materials :

  • They are non-wettable to molten aluminium.
  • They can withstand thermal shocks from 800C to room temperature without cracking.
  • They can be cut or machanined easily, so that lining of any curvature or critical shape is easy.
  • Pre heating is not required.
Comparison of CERAL SHAPES with normal refractory lining
Sr. No. NORMAL REFRACTORY LINING CERAL SHAPES
1 Wastage of metal due to sticking lowers down the yield of metal. Non wetting property gives maximum yield of clean metal.
2 Loose refractory material which is bounded with Binder &/or hydraulic bond leads to refractory inclusion which affects the quality. Pre shapes properly heat treated do not give any refractory inclusion hence pure metal is available.
3 Every time preheating is required which is a recurring cost. Preheating is not required hence more economical.
4 Very short life & repeated patching leads to higher consumption of refractory material & thus more down time. Life of lining is very high due to higher thermal shock resistance hence no recurring cost & down time.
5 Individual lining cost is less but cumulative hidden cost of down time, heating & labour is Higher with chances of inclusions. Basic cost is higher but still economical. No any further cost, Higher life & No Inclusions.
