Steel billets bars and rods britannica,steel steel billets, bars, and rods: billets are the feedstock for long products of small cross section. In cases when they are not directly cast by a continuous caster, they are rolled from blooms by billet mills. one method of rolling billets, which are usually to 125 millimetres square, is to use a three-high mill with box passes, as shown in in the figure.

continuous casting, also called strand casting, is the process whereby molten metal is solidified into a "semifinished" billet, bloom, or slab for subsequent rolling in the finishing mills. prior to the introduction of continuous casting in the steel was poured into stationary molds to form ingots.since then, "continuous casting" has evolved to achieve improved yield, quality jan 31, 2015 cement concrete floor section. first properly compact the earth in the plinth. while compacting, care has to be taken that a proper slope as required for the floor is provided. over this compacted earth filling, uniformly spread a layer of clean coarse sand about to cm thick.

this is often the case when casting thin cross-sections in short times using metal molds. mold thickness is usually large compared to the cross-section of cast metal. this situation is shown in fig. 1.11. In this case heat transfer in the ingot and mold are so fast that it is the interfacial heat transfer that controls how fast heat is transported.cement mill grinding mediapage of nov 01, 2017 re cement mill grinding media. there, these are just the basics if you want to accurately do it you have to fill it up to 80% BC and then do a longitudinal sieving and then correct the BC based on the results.
