The Main Uses of High Alumina Mortar

For Construction

We can widely use calcium aluminate mortar in masonry and lining construction of high heat bricks, refractory castables, etc. Moreover, its excellent bonding performance and high temperature resistance enable it to play an important role in the lining construction of high-temperature equipment. Such as blast furnace, rotary kiln, melting furnace, etc.Refractory Mortar Used for Fire Bricks

For Maintenance

During the operation of high-temperature equipment, the lining material may be subject to thermal shock, chemical attack and mechanical wear, resulting in localized damage. What’s more, we can commonly use high alumina refractory mortar for the repair and maintenance of this equipment. This extends its service life and reduces downtime.Application of Ramming Mass

Kerui High Alumina Mortar Application Cases

Steel Plant Blast Furnace Lining Repair

At a large steel plant in Pakistan, the blast furnace lining suffered severe wear and cracks due to long-term exposure to high temperatures and chemical attacks. They used Kerui high-aluminum mortar to repair and reinforce the lining. Moreover, they say this avoids high replacement costs and greatly improves overall productivity.

Kiln Mouth Sealing of Cement Plant Rotary Kiln

The sealing effect of the rotary kiln entrance of a cement plant in South Korea was poor, resulting in heat loss and environmental pollution. After the successful implementation of the sealing renovation plan use of high alumina cement mortar lining, the heat loss at the kiln entrance was reduced by 20% and exhaust gas emissions were reduced.

Glass Factory Furnace Head Repair

The furnace head of a glass factory in Russia experienced peeling and cracks due to long-term high-temperature operation. After they use Kerui’s high alumina mortar to repair the kiln head, it enhanced the structural stability and reduced unexpected shutdowns. This improves glass product quality and extends the life of the furnace.

Cracking Furnace Refractory Layer Maintenance

The refractory layer of a cracking furnace in an Italian petrochemical plant cracked and fell off under the action of high temperature and chemical media. Through Kerui’s high alumina mortar maintenance program, the overall performance of the cracking furnace has been enhanced and the maintenance cycle has been extended.
