Raw materials for refractory products

Raw materials for refractory products. Refractory products generally consist of a mixture of coarse and fine grains and a binding agent. The aim is to achieve the highest possible packing density, i.e. low porosity and high solidity. Ideally, the formula should show a steady grading curve with directly adjacent grain classes.

Refractory

When refractory materials are fired, the individual particles do not melt but they do fuse together at points of contact.This type of bonding (where little or no glass formation is occurring) is called sintering. The fusion of particles can take place at relatively low temperatures to give the product adequate service strength.

Sintered

Sintered spinel MgAl 2 O 4 is a synthetically produced raw material available with an excess of either Al 2 O 3 or MgO and used in many refractory applications. MgO rich spinels are mainly used as alternative to magnesia chrome bricks in MgO-based refractory products, e.g. in cement rotary kilns, in order to avoid the emission of Cr VI during the break-out of bricks, which may be dangerous for

Understanding Refractory Failure—A New Perspective

Refractory has always been an integral part of steam-generating boilers. In the steam-generating industry, refractory materials are used for filling gaps and openings to help keep the fire inside the fire box, for lining ash hoppers (wet and dry) that collect ash and slag, and for the protection of lower furnace wall tubes inside fluidized bed, cyclone-fired, or refuse-derived fired boilers.
