Can a steel furnace have more than one batch?Can a steel furnace have more than one batch?Heat can be divided into several batches, the same number of hot plate sizes can be the same, materials are different but must be the same level of steel; through heat treatment process, the furnace can have more than one batch.Difference between heat and batch number Heat or cast numbers - Metal and Metallurgy engineering Difference between heat and batch number rainbow steel

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.

What does a heat lot number tell you about steel?What does a heat lot number tell you about steel?The heat lot number identifies the steels chemical composition. Manufacturers can track individual steel lots back to the raw material suppliers based on this lot number.
