Bulk Density Of Fused Cast series Block
2015-06-26
Bulk density is a useful property of fused cast series block, which can reflect the function for structure of blocks and influence the physical and chemical features such the resistance to slag, thermal shock resistance, cold crushing strength and corrosion resistance to glass liquid. What is called bulk density? Simply put, it is an indicator of weight for unit volume bricks, bulk density is that the weight of fused cast block divided by the total volume.
There are various of shaped fused cast series block which is not very evenly shaped and some of them has quite a rough surface. So, how can we measure the bulk density of fused cast series block? First of all, we need to know that bulk density is weight/volume, weight is relatively easy got as the brick can be weighed in air. As to volume, there is a method which is called water displacement method to measure.
Water displacement method
1. Load a certain amount of liquid into the appropriate vessel and record the volume(V1).
2. Put a fused cast block into the liquid and submerge it totally, accordingly the volume will increased, and record this volume (V2).
3. The volume of the submerged fused cast block is the same as the increased volume of liquid displaced which equals to V2 minus V1
After get the volume of fused cast block，the density can now be calculated
