The Application Value of Kerui High Alumina Mortar
Its main components are high-purity alumina and aluminum silicate. Therefore, Kerui high-aluminum mortar has excellent fire resistance and corrosion resistance. Use it to reduce the frequency of repairs and replacements. So, this reduces the company’s operating costs and improves production efficiency.
Although the raw material cost of Kerui calcium aluminate mortar is relatively high, it has a long service life and good fire resistance. This can effectively reduce equipment maintenance costs and downtime. Therefore, taken together, the overall cost of Kerui’s high-aluminum mortar is relatively low in long-term operations.
You can pour or spray the Kerui best mortar for firebrick according to specific construction needs. The construction process is relatively simple and quick and does not require highly complex equipment and processes. So, this reduces the construction period and labor costs and improves construction efficiency.
The Main Uses of High Alumina Mortar
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.
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.
Kerui High Alumina Mortar Application Cases
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.
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.
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.
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.
