Due to higher proportion in the production of domestic hot - rolled plate and coil, full production capacity. 2004 domestic hot rolling mill production of 47.4 million tons, representing a growth of about 30. 2005 first half of this new production of hot rolling mill includes 1500 1880 at Benxi steel, laiwu steel, sand steel mills such as 1700, added production capacity of 9.5 million tonnes, the current domestic hot rolling mill total to 57 million tons. 2005 - July total cumulative 31.59 million tons of hot rolling mill of hot rolling production, per cent increase of 5.48 million tons, an increase of 21. In addition to hot - rolled plate and coil outside 16.91 million tons, under the thin volume included for cold - rolling step 9.71 million tonnes, hot - rolled wide strips volume 4.93 million tons of goods. There will be general steel in China in the second half, Liu gang, Kunitoyo, eight steel production line completed, new capacity of 6.5 million tons is expected, that is, the hot rolling mill capacity throughout the country by the end of this year will reach 63.5 million tons. Domestic hot rolling production for the whole year is expected to be achieved 56.5 million tons, including 30 million tons in the coil, 26.5 million tons of sheet products. Under 1 sheet products in China import and export situation, class of domestic sheet steel imports for the whole year is expected to be 13 million tons, that is various domestic sheet class consumption to about 40 million tons of steel, basic and flat from a year earlier.
