Continuous casting slabs or primary rolling slabs are used as raw materials, heated by a stepping furnace, and dephosphorized by high-pressure water, and then enter the roughing mill. The rough rolling material is cut through the head, tail, and then into the finishing mill, and computer-controlled rolling is carried out. After the final rolling, it will go through laminar cooling (computer-controlled cooling rate) and take-up by the coiler to become a straight hair coil. The head and tail of straight hair curls tend to be tongue-shaped and fish-tailed, with poor thickness and width accuracy, and often have wavy, folded, tower-shaped and other defects on the edges. The coil is heavier and the inner diameter of the steel coil is 760mm. (Generally used in the pipe-making industry.) After straightening the hair through the cutting head, tail cutting, trimming and multi-pass straightening and smoothing finishing lines, and then cutting or re-rolling, it becomes: hot rolling steel plates, flat hot rolled steel coils, slitting tapes and other products. If the hot-rolled finishing coil is pickled to remove scale and coated with oil, it will become a hot-rolled pickled coil.

The reporter learned from the national coal contract summary meeting that in 2007 the national coal, chemical fertilizer, coking and other industries used coal contracts have all been signed, non-electric coal average price increase of 3% to 5%. Coal prices in Heilongjiang Province rose by 25 yuan, coal prices in Shaanxi Province rose by 20 yuan, and coal prices in Shanxi Province rose the most. Datong Coal Group plans that the price of electric coal vehicles has risen from 265 yuan per ton to 305 yuan per ton, up 40 yuan, an increase of up to 15%.
China's five major power group coal contracts have been basically completed, the national tons of coal rose an average of about 30 yuan, with an average increase of about 8%.
The data from the coal contract summary data center shows that 1.2 billion tons of coal ordering contracts were entered into this contract summary meeting, of which the signed amount of thermal coal contracts reached 723 million tons, both exceeding the national coal capacity distribution framework plan for inter-provincial regions in 2007. The regula- tory targets set at 738 million tons and 531 million tons have achieved remarkable results.
Ou Xinxuan, deputy director of the National Development and Reform Commission, said in an interview with reporters: “We have changed the way in which the government has organized continuation of the ordering meeting between the supply and demand sides for more than 50 years. We have adopted the state’s macro regulation and control, and the enterprises have autonomously connected resources and negotiated pricing. The new mechanism, this move is in line with the development of the times. The National Coal Contract Meeting held in Guilin marks that China's Coal Ordering Association, which has lasted for more than 50 years, has completely bid farewell to the historical stage and is dying."
Since the full marketization reform of coal orders was implemented this year, the supply and demand sides of coal basically agree with the increase in coal prices at the National Coal Contract Meeting. Zheng Dong, secretary-general of the East China Coal Sales Consortium, said that in the past, the power generation company “held the group†monopolized the price discourse. This year, all contracts were directly signed by coal sales companies and purchasing companies. Power plants under the power generation group also negotiated directly with coal companies. Everyone is "quiet and talks very well." Zhong Juen, general manager of China Energy Power Co., Ltd. said that coal companies now have a price discourse, and power companies can only accept coal prices.
Coal prices in China are on the rise this year
At the just-concluded National Coal Contract Meeting, relevant experts pointed out that China's coal prices have generally risen this year. Among them, Shanxi coal has the highest price increase, with an average increase of 40 yuan per ton.
