What is Fire Cement?
The raw materials of the best fire cement are high erformance bauxite and excellent lime. Firstly, we mix the raw ingredients into the right amount of ingredients according to a certain fire cement recipe. Then, we grind the clinker containing aluminate as the main component obtained after sintering into fine powder. Finally, we made refractory cement, also called aluminate cement. In addition, The refractory degree of refractory cement is not less than 1580 ℃(2876℉).

Excellent Features of Kerui Fire Cement
Flexible fire cement maintains its physical and chemical properties in high temperature environments. Therefore, it can withstand high-temperature sintering and long-term high-temperature exposure and is not prone to thermal cracks.
Refractory cement has a strong resistance to chemicals such as acids and alkalis. What’s more, it can resist the erosion of corrosive gases, acidic or alkaline solutions and other chemical substances, maintaining the stability of the structure.
Our fire cement for sale resists physical wear and friction. So, this makes Kerui fire cement perform well in situations where it needs to withstand high pressure, high velocity fluids or particulate matter. In addition, we extend its service life.
It can be shaped into different shapes and sizes as needed to adapt to various complex construction requirements. That is to say, Kerui fire cement makes it easy to operate during the construction process, improving construction efficiency.
The Uses of Fire Cement
The fire cement is one of the main components of refractory castable. In addition, flexible fire cement is highly plastic, making it easy to construct and apply. This allows the refractory castable to be adapted to equipment lining needs of different shapes and sizes.
The lining of the furnace can be reinforced by using the best fire cement for furnace repair. This therefore restores its fire resistance and structural integrity. In addition, fire cement can resist the erosion of corrosive gases and ensure the safety of the furnace.
In the petroleum and chemical industries, fire cement is used to line storage tanks, reactors, pipelines and other equipment. Moreover, the high temperature resistance and chemical stability of cement for fire make it an ideal refractory lining material.
In metallurgical processes, refractory cement can be used to make karge refractory bricks. We use it for the lining and protective layer of smelting furnaces and converters. The wear-resistant properties of buff fire cement allow it to protect equipment from wear and tear.
How to Apply Fire Cement？
- Fire cement slurry Preparation: how to mix fire cement? Mix fire cement powder and clean water according to the fire cement instructions. Moreover, we need to control the fire cement mix ratio. Then, stir well until a homogeneous cement slurry forms.
- Apply the first layer: use spray equipment to evenly apply the first layer of waterproof fire cement to the base surface. Besides, we must ensure that the grout is tightly bonded to the base to avoid voids and cracks.
- Dry and cure: allow the first layer of refractory cement to fully dry and cure. Determine fire cement drying time according to the instructions we provide. Therefore, this can maximize the use effect of fire cement.
- Apply extra layers: apply additional layers of best fire cement as needed. Most importantly, ensure that each layer of grout is of uniform thickness to achieve the required fire resistance and protection.
- Final cure: after we applied all the layers, we allowed the buff fire cement to set and dry overall. Generally, it is important to avoid applying any load or stress to the refractory cement while it is curing.
