Refractory Castable for Repairing the lining of the kiln
What is the use method of refractory castables?
1. Generally, the mixer is used. The first step is to pour the castable into the mixer and ensure that the coagulant amount is 3% or 5%.
2. To add coagulant, it is necessary to add 3% of the amount (the amount can be increased to 5% by on-site operation), and it is necessary to ensure that the time used during on-site construction is controlled within 10 minutes as much as possible.
3. Before pouring, it is necessary to do cleaning work first, and then apply a layer of asphalt. If the thickness of the glue injection is controlled within 250 mm, it is necessary to ensure one-time pouring, and then vibrate to the secret chamber.
4. It is necessary to apply engine oil on the surface of the mold when sizing.
What should be paid attention to during the use of refractory pouring materials?
1. Before using refractory pouring materials, it is necessary to test the quality and bearing capacity of the pouring ladle. All construction must be built on a reasonable basis to ensure the completion of the later construction. Therefore, it plays an important role in the previous test before use to ensure that the subsequent construction can be formed at one time without any accidents.
2. We also need to pay attention to the inspection time. The method you can use is crane pouring or portable pouring, but it must be checked regularly. It is necessary to control the inspection time within two months, and pay attention to the deformation and expansion of each part during the inspection.
3. In addition, the environmental requirements during construction also need to be paid attention to, because there are strict requirements for the use and control of materials when used in different environments and weather. If the temperature will be around 20 degrees during the construction period in autumn or spring, you should control the injected materials and increase the dose a little..
