Improved container plate producing process
A production method and container technology are applied in the field of thin slab continuous casting and rolling process to produce hot-rolled container plates, which can solve the problems that thick-gauge products are prone to cold working cracks, the product strength cannot be reached, and the products cannot be produced, and improve cold working. performance, the effect of increasing the tapping temperature and finishing temperature, and increasing the strength
