Since 2020, the foreign trade industry has been significantly affected by the epidemic. In the first two months of this year, China's SM400B carbon steel plate sheet and so on steel exports totaled 7.811 million tons, down 27% year-on-year, the largest decline since March 2018. In terms of steel foreign trade, China is mainly a steel exporting country, with less steel imports.

Advantages of hot rolling: hot rolling can destroy the casting structure of ingot, refine the grain of steel and eliminate the defects of microstructure, so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction, so that the SM400B carbon steel plate sheet steel is no longer isotropic to some extent; the bubbles, cracks and looseness formed during pouring can also be welded under the action of high temperature and pressure.
