一、直送轧制与直接轧制近年来,炼钢技术在连续、高速、优质等方面有了显著发展,今后将会继续发展。由于连续铸造方法的出现,使铸坯过程实现了连续化,另一方面轧制过程的连续化也早已实现,因而,连铸与轧制之间的连续化,就成为急待研究的课题。铸造与轧制的连续化,大体可分为直送轧制和直接轧制两种。直送轧制是指把铸坯按照定长切断后,趁铸坯还没有完全冷却即送去轧制的一种方法。这种方法虽然与产品本身 First, the direct rolling and direct rolling In recent years, steelmaking technology in continuous, high-speed, high-quality has made significant development, the future will continue to develop. Due to the continuous casting method, the continuous casting process is realized. On the other hand, the continuous rolling process has long been realized. Therefore, the continuous casting and rolling becomes an urgent research topic. Casting and rolling of the continuous, generally can be divided into direct delivery and direct rolling two. Straight rolling refers to the slab cut in accordance with the fixed length, the slab has not been fully cooled that is sent to the rolling method. Although this method with the product itself
