Cracks and chips in kiln refractory can be permanently sealed with AMACO Kiln Cement Mix water with the dry cement for a smooth plastic consistency The prepared cement is ready for immediate use When mixed with coarse grog or pieces of refractory cement may be used to repair large holes in firebrick

Calcium Aluminate cement and Lime will work the best as the cement in hot cooking conditions This applies to refractory concrete as well as to heat resistant mortars Lime is sometimes mixed into fire clays This is mixed like a normal cement based mortar but with half the cement replaced with the lime

Refractory Materials for Furnace are a kind of inorganic nonmetallic materials with various excellent performances on application for industrial furnace such as glass furnace cement kiln ceramic kiln and coke oven There are various high temperature refractory materials for refractory

The purpose of the refractory lining is to insulate the steel shell from the high temperatures inside the kiln and to protect it from the corrosive properties of the process material It may consist of refractory bricks or cast refractory concrete or may be absent in zones of the kiln that are below around 250 C
