In the first quarter, the country produced 12,447,000 tons of steel, of which 9,182,700 tons (including flat furnace steel 2,393,500 tons, 1,052,200 tons of electric furnace steel and 5,212,300 tons of converter steel) were produced by key enterprises. The steel output includes 1,247,400 tons of low-alloy steel and 56,950 tons of alloy steel, both of which are the best in the quarter. The country produced 1,548,800 tons of continuous casting billet (continuous casting ratio of 12.08%), of which the key enterprises produced 1,213,100 tons of continuous casting slabs (continuous casting ratio of 13.19%), flat hearths and converter castings of static-insulated steel plates of 3,313,500 tons , Argon processing molten steel 2,881,600 tons, all over the same period last year level.
