The operation of corundum castable

We usually do not know how many of corundum castable understand, then give you some tips and tricks, discuss with you today is the knowledge of its sample. The following summarizes the four o’clock related content, you can carefully read this:

1. When the sample production and maintenance, the ambient temperature is 20 ℃ ± 1 ℃. Using 40mm × 40mm × 160mm mold making.
2. When the ingredients must first aggregate, (A + B) and part of the cement binder Stir respectively, and then press the 93:7 (A + B): 0.15 Weigh aggregates, cement binder. The weighed aggregates, cement and additives used in the experiment into the dry mix mortar mixer for 2-3 minutes, then add clean tap water, add water to the total weight of material 4.8 to 6% (press the lower water, in pourable performance guarantee provided to minimize the amount of water), stir 3 to 5 minutes until construction material has good plasticity, can be cast.
3. Good material into the wet mix tryout, on the vibration table to make it sufficiently dense vibration.
4. Forming complete specimen placed 20 ℃ environment conservation with mold release after 36 ~ 48h, after stripping the sample before drying treatment after 48 hours and then the Nature Conservancy.

These are the relevant content corundum castable sample operation, we can refer to, and I hope to help you understand the product. Today’s content introduced here, want to know more you can continue to focus on our product knowledge.
