However, in order to fully cool, neatly collect, and efficiently remove the billets of double-length rebars, this process poses severe challenges to the cooling and collection equipment. There are two major problems in the existing technology: 1) Due to the thermal expansion and contraction effect of rebar, the steel will shrink from both ends to the center during the collection process.
