The Coal Mining Administration of Shaanxi Province was informed that: In the cold weather of the coal market in 2014, the production and sales of coal in Shaanxi Province increased in a contrarian fashion. The annual production of coal was 515 million tons, an increase of 21.8254 million tons, sales of 501 million tons of coal, and an increase in sales of 21,613,500 tons. , year-on-year increase of 4.34% and 4.51% respectively.
It is understood that in the last year, the downward pressure on the economy continued to increase, the coal market continues to be weak, and coal production and sales in other coal-producing provinces have generally declined. The third place in the country. There are four reasons for this: First, Shaanxi Province has taken effective measures to reduce the burden on coal companies, eliminate some unreasonable local fees and taxes, stop the coal price adjustment fund, reduce the toll of coal transportation vehicles by half, and so on; Market judgments and guidance, timely collection of timely release of coal production, sales, deposits and price dynamics information, introduction of coal price Shaanxi index; third quality promotion, strengthening "Yulin" coal, "Yulin blue carbon" and other high-quality coal promotion and marketing Improving the market share; Fourth, reducing intermediate sales, vigorously promoting network transactions, and producing and using direct meetings.
At the same time, Shaanxi Province has further optimized the coal industry structure. First, it has stepped up the elimination of backward production capacity. Last year, 22 small coal mines that did not meet safe production conditions were shut down, and 5.66 million tons of outdated production capacity was eliminated. The Shaanxi Coal Chemical Group took the lead in shutting down 7 mining conditions with a total capacity of 6 million tons, coal mines with poor coal quality and poor market prospects. The second is to accelerate the integration of resources and mechanization of small coal mines, and add 9.68 million tons of new production capacity. Third, the amount of large and medium-sized coal mines and high-quality coal resources has further increased, accounting for 93.2% of the province's total production. Fourth, the level of coal technology has been further improved. The province’s mechanized coal mining reached more than 90%, 9 sets of new gas drainage systems were established, the gas drainage capacity reached 30,000 cubic meters/min, and 60 mines met the first-class safety and quality standards, which strongly promoted the safe production of coal mines in Shaanxi Province. The one-million-ton mortality rate is only 0.1% lower than the state's issued control index and 60% lower than the national average.
BRIGHT STEEL BAR
Bright steel bar is carbon or alloy steel bar with shining bright surface which is improved by cold drawing, peeling, turning, grinding and polishing over hot rolled black surface bars. By cold drawing, the steel bar yield strength and tensile strength will be improved. By peeling and turning, the surface imperfections will be removed. By grinding, the diameter tolerance will be more precision. By polishing, the surface will be much more shining.
Except the shining bright surface, comparing with the hot rolled black surface bars, the bright steel bars has better surface roughness, better roundness, straightness, more precision size tolerance etc.
Heat treatment such as annealing, normalizing, quenching and tempering will be done before do cold finishing on the hot rolled bar to get bright steel bar, in such condition, the steel bright bar will get most suitable mechanical properties to meet different application requirement.
The advantages of steel bright bars we supply:
1) Big stocks of hot rolled round bars or wire rods as raw materials
2) Heat treating furnaces to adjust the mechanical properties
3) Full sets of testing equipment to test the sizes, mechanical properties and microstructure.
4) Multiple packages to avoid broken packages and anti-rusty
