Corundum Mullite Castable Specification

Corundum Mullite Castable Application

Corundum mullite refractory castable using in the lining of coal kiln before and after large cement kiln, coal injection pipe and other industrial kiln lining.
Corundum mullite refractory castables are widely used in large and medium sized cement kiln kiln mouth, coal injection pipe, kiln head cover, cooling machine low wall.
Corundum mullite refractory castable is widely used in circulating fluidized bed boilers, metallurgy, petrochemical, thermal power and other professional fields.
Corundum mullite refractory castable can be used for lining of large power station boiler wear linings and other high temperature furnaces

Corundum Mullite Castable Precautions

1. The surface temperature level of the sinter material is increased, the high temperature operation time is prolonged to obtain sufficient heat, castable corundum mullite is conducive to the consolidation of the surface powder and the strength and yield of the surface sinter. The current problems of the above methods are: the refractory material of the ignition and holding furnace is seriously washed by the airflow, the service life is short, the construction time of the removal and replacement is long, especially the oven is long.

2. In order to shorten the production stoppage time, researchers combined with the actual situation of production and construction, using a new material — sol combined with corundum mullite castables to replace the traditional mullite castables. The early strength is high, the curing time is short, and the production can be resumed simply by baking, castable corundum mullite greatly shortens the construction period and achieves good economic results.

3. Generally, the ignition holding furnace adopts a mullite castable and a heat insulating product to hang the refractory brick through the heat resistant anchor to form a composite composite refractory lining, castable corundum mullite has low price, high temperature performance, easy sintering, high strength, castable corundum mullite is not easy to crack and resist. Erosion, anti-wear. However, after stirring and shaking with water, castable corundum mullite takes 24 hours to remove the mold. After 48 hours of natural curing, the oven can be oven dried for at least 72 hours to ensure moisture discharge and no bursting.

4. Castable corundum mullite only takes 6 days from the mixing and pouring to the mold removal and then to the oven. Castable corundum mullite does not include the process of dismantling the original furnace body, setting up the scaffolding, laying the furnace wall and the top of the furnace, demolishing the mold. At least 15 days.

Corundum Refractory Castable Instructions

1.Corundum Castable Refractory Stirring
Stirring is carried out by a forced mixer. Each bag is an integral unit. It can be stirred in multiple bags according to the actual dosage. The construction temperature is 5 ℃-35 ℃. When the temperature is low or high, the heating or cooling measures must be adopted to meet the construction temperature requirements.

2.Corundum Castable Refractory Stirring Method
firstly put the refractory aggregate and the binder into the forced mixer, dry the dry material for 2 minutes, make the color of the material uniform, and then add water for 3-5 minutes until the material color is uniform. The agitated material can be agglomerated by hand but not leaking.

3.Corundum Castable Refractory Add Water
6-8% of the weight of refractory castable materials, can be properly floated according to weather conditions, water must be clean drinking water. Refractory corundum castables must be completed within 30 minutes after mixing with water. is strictly forbidden to return material and stir mixing construction and secondary water mixing.

4.Corundum Castable Refractory Vibrating
Corundum castables should be cast by insert vibrator or flat vibrator. The casting height of each layer shall not exceed 400mm. The vibration of each layer may cause the surface to be slurry. In one part, Corundum castable refractory material shall not vibrate for a long time to prevent the material particles from being graded or the template being displaced. Corundum castable refractory material must be vibrated by vibrator during construction, manual vibrating construction is not allowed.
The pouring material should be continuously carried out during construction. Before the initial pouring of the previous layer, the next layer of castable should be poured. If the construction gap exceeds its initial setting period, Corundum castables should be treated according to the construction joint requirements.

5.Refractory Castables Maintenance and Demoulding
After the pouring, natural curing can be demoulded after 24 hours. After the corundum castable is poured, Corundum refractory castables can be naturally cured. Castable refractory corundum can not be watered during curing, and the curing temperature is 5 ℃ – 35 ℃. After curing for 72 hours after demolding, castable corundum refractory can be baked according to the heating curve.
