For example, it is not known whether similar types of furnaces were constantly operated throughout the last two millennia. Excavations at two sites in northern Ziabwe, one Gokomere-Ziwa (800 - 1200 cal AD) and one Ziabwe tradition (1500 - 1700 cal AD), have shown differences in iron pyrometallurgical debris, tentatively suggesting that they represent separate metal working practices.

Furnaces No. 1 and No. 2 had a hearth diameter of 9,1 m. Because of the lack of a deep-water iron ore unloading terminal the iron and steel making facilities, including the three 175 t converters of the BOF shop, where closed down in 2001 after producing steel
At no other place in the steel mill is process reliability as important as at the blast and arc furnaces. For once it is commissioned, a blast furnace is used around the clock over the course of years. Continuously and reliably managing high temperatures and magnetic
the volume ranges still remained the same, but the total nuer of blast furnaces increased from 196 to 475. After 2006 the Chinese iron production capacity in blast furnaces with an inner volume of less than 1000 m3 went from 41% to the current level of 19%.
They, therefore, had to manufacture a large volume of efficient iron cannons at low cost, and accordingly reverberatory furnaces were constructed at several places in the country. However, only two of them remain in two places (Nirayama and Hagi) at present, and the one at Nirayama is the only one that retains most of its original form.
