Jan 20, 2006Depending on the steel supplier, this will be ~ 10 tons to over 200 tons. A cast number then identifies where this steel was cast. For steel suppliers that have multiple strand casting, one heat of steel can feed up to 6 casters at the same time. This means 1 heat number would then be divided into 6 different cast numbers.
A heat number can be divided into several batches, the same number with the same heat plate size can be different, the material is not the same but must be the same level of steel; a furnace can have more than one batch, with the heat treatment process. Sometimes, you will see the lot number If Gr.b this material manufacturers a lot, certainly produced a lot of furnace, and then shipped to be issued in lot, there is one for each batch number. Therefore, the same lot number, different heat Difference between heat and batch number rainbow steel
