Project Description

Product Name INDUCTION FURNACE – NEUTRAL LINING 
Description The selection of refractory lining is a key for coreless induction furnace. SH Refractories has engineered the next generation Neutral Ramming Mass which enable induction furnace to reach the longest possible life with optimum cost in current harsh competition.

MEGATHERM RAM85A-CR2 the Top-Class High-Performance Neutral Lining Material with the addition of Chromium Oxide, has high refractoriness and excellent corrosion resistance in various environments.

Introduction of Neutral Lining: –

a. volume expansion and provide rigid structure.

b. hard sintered refractory surface layer resistance to metal bath and erosion.

c. The inner refractory layer remains as powdery form.

d. As soon as the top layer eroded, the next inner layer exposed to the metal bath and become sinter by in situ spinel formation.
