One arc furnace with capacity of 180 tons is under construction now.It will produce 1 million 300 thousand tons of steel a year. 600 employees are working here.It will be launched in spring 2012.
No matter it is knot type furnace lining or fabricated furnace lining, when for long time working under the high temperature it is certain to change (mainly is expansion and contraction or oxidation).
不管是打结式炉衬，还是装配式炉衬，长期在高温下工作都会发生变化（主要是热胀冷缩和氧化）。
