subject: Steel Enterprises In The Next Big Challenge Coke Blast Furnace Iron Ore Followed The Steps - Large [print this page] Although high iron ore prices in China Steel Enterprises are the most troublesome problem, but after a few years, coke enterprises may be constrained by another steel major problem.
"Now a lot of steel building experts asked 5000,4000 cubic meters of blast furnace, coking coal, but most of China can only meet less than 1500 cubic meters blast furnace needs." May 12, Beijing University of Science and Technology, Professor Xu Zhongbo, said five years We do not talk about the possible iron ore, and to talk about coke imported.
Imports last year after a net increase of four times, the first two months of this year, China imported coking coal has surged nearly 4 times the volume. Xu Zhongbo worried that if the domestic large-scale construction of large capacity blast furnace, will inevitably lead to the already tight supply of resources becomes increasingly dependent on coke, coking coal could become "a second iron ore crazy."
Large volume of blast furnace Take into account Energy Environmental protection Demand, the state departments concerned to formulate the "Steel Industry Development Policy", iron and steel industry, the following should be phased out 1000 m3 blast furnace, blast furnace new furnace must be large. Currently, the domestic plot ratio from the largest private steel enterprises sand blast furnace steel group. Last year on October 21, Sha Steel Group 5.8 thousand cubic meters blast furnace official ignition, once the iron capacity by 500 million tons. Second, Shougang and Tangshan Steel in Hebei Caofeidian steel project launched, its blast furnace to 5500 cubic meters, the project has been put into operation last year. Comparing the two blast furnaces, old Bayuquan Angang Steel 4050 cubic meters of blast furnace project have been significant "backward."
Moreover, in order to reduce energy consumption, the scope of the domestic CP to blast out of a small volume. February 6, the State Council issued "on the elimination of backward production capacity to further strengthen the work of the notice" clearly provides that the end of this year, the steel industry will phase out 300 cubic meters and below blast furnace, 20 tons and below, converter and electric furnaces, will be the end of 2011 then out of 400 cubic meters and below blast furnace, 30 tons and below, converter and electric furnace.
"Blast furnace has advantages such as labor productivity, environmental costs declined significantly, but its fatal weakness is that domestic coke quality is unlikely to fully meet the large volume of the blast furnace." Anshan Iron and Steel Group's total original Project Master Dragon Spring, said in an interview.
High coke quality requirements Dragon Spring, said blast furnace requires a large floor area ratio of the coke drum index is relatively high, that coke strength and abrasion resistance to be high, especially for more than 5,000 cubic meters of blast furnace coke requirements for particularly high. High strength, must rely on high-quality coking coal and coke, fertilizers gas coal, fat coal, ratio of lean coal, etc., to get the maximum index of the real drum, and then get the real high-quality coke.
Joint metal coal Channel One analyst told the newspaper, more than 5,000 cubic meters of blast furnace, coke can not meet the domestic level, you must use the ultra-a coke. Shougang
two views of an expert opinion and consensus. As the Shougang Caofeidian launched in 5500 cubic meters of blast furnace, the most say in this company. Shougang experts told the newspaper, the project used Caofeidian not all dependent on imported coking coal, but must be part of high-quality coking coal imports, and domestic coking coal to match.
From last year, Angang Steel Company began importing coking coal resources from abroad. Prior to this, procurement of Angang Steel Company Limited mainly domestic coke. In this regard, Angang Steel Company secretaries to directorate told the newspaper will pay Kyrgyzstan last year, coking coal is mainly imported from abroad than domestic coking coal prices low, not technical reasons. In his view, the domestic coking coal project in the technology can meet the requirements of Bayuquan.
"However, domestic coal prices now almost." Fu Ji will say.
