Centrifugal Casting of Refractory Concretes
· The investigation revealed that the major controlling factor in the production of the centrifugally cast pipe was the workability of the refractory concrete. Coal gasification processes require refractory linings in the gasifier unit transfer lines between the preheaters and the gasifiers and exhaust lines leading to the gas scrubbers.

Materials Free Full-Text The Effect of Refractory Wall
The effect of high emissivity coatings on the radiative heat transfer in steam cracking furnaces is far from understood. To start there is a lack of experimental data describing the emissive properties of the materials encountered in steam cracking furnaces. Therefore spectral normal emissivity measurements are carried out evaluating the emissive properties of refractory firebricks before

Understanding Refractory Failure—A New Perspective
Failure to properly cure a cement-bonded refractory material is the number one contributor to refractory failure and lack of longevity. Curing allows the chemical action to take place inside the refractory and helps ensure that the refractory can reach its maximum strength when properly dried. It is recommended that the surface of the
