Heat and batch number are equivalent to steel ID card. Heat number refers to the number of furnace. Each furnace is made into component analysis. Heat number refers to the quality of steel. The batch number is the heat treatment of the steel label. Mechanical analysis and technological performance test are performed for each batch of products. Heat and batch number are proof of traceability of steel.


The number of heat is the number of steelmaking furnaces. The quality and quality of steelmaking can be checked according to the number of furnaces, because the data of each steelmaking laboratory are recorded. Component testing and mechanical testing are done for each tapping furnace, and the composition and performance of tapping steel are different for different furnaces.


Batch refers to the same batch of steel production in the same batch, each batch of products have to do mechanical analysis, inspection process performance, batch number is the certificate of steel development. According to this batch of steel raw material data can be found, you can also find the number of heat according to the batch number. 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.


Sometimes, you will see the batch number: if Gr. B is a material manufacturer of many, it must produce a lot of stoves, and then shipped to the batch, each batch has one. Therefore, there may be the same batch number and different calories, but if there is a quality problem, you can look at the furnace in question. The same batch number, each furnace in the process, will be somewhat different within the allowable range. Furnace can have more than one batch, heat treatment process normalization treatment, plus a group of heat treatment.
