A new type of converter process for steel making, i. e., the side-blownconverter process with oxygen tuyeres in double row is presented in thepaper. The advantage of dynamics and the rationality of process are laystress on theoretical analysis hereon, and formulae for the avereage horizontalvelocity of bath metal flow and the inclination applicable to tuyeres on upperrow both have been suggested. The practice of side- blown converter processwith oxygen tuyeres in double row indicates that the obvious improvementson the effects of slagmaking and splashing and the steel quality may be achie-ved as well as the manipulation improved, thus probably bearing out that sucha process would be a new kind of strengthened blowing process for melting.

Thus, they have advantages such as: quiet blowing, high metal yields, outstanding desulfurization and dephosphorization, intense mixing of the bath resulting in rapid carbon removal to very low levels. Since the installation of the first production unit to date, the new steelmaking process has reached an installed capacity of 35 million T/y, and new progress has been...

Bottom-blown converters have many tuyeres at bottom to blow in oxygen, and at the same time to inject lime powder through the tuyere with oxygen. Thus, they have advantages such as: quiet blowing, high metal yields, outstanding desulfurization and dephosphorization, intense mixing of the bath resulting in rapid carbon removal to very low levels. Since the installation of the first production unit to date, the new steelmaking process has reached an installed capacity of 35 million T/y, and new progress has been made in technology by Q-BOP/OBM. For example, at the Kawasaki Chiba works, gas recovery for Q-BOP is 125.5 Nm~3/T. The life of furnace lining for one campaign is 3150 heats and bottom life for one campaign 1646 heats. Turn-down performance of existing Q-BOP facilities is 96.1%. All these major advantages will certainly bring bottom-blown oxygen converter process a very bright future.

Hot metal from Baotou blast furnace contains about 0.08% of niobium and 1% of manganese. The openhearth slag accumulated at that steelplant also retains appreciable amounts of these metals. A process has been developed, using a small blast furnace and side-blown converter for collecting niobium and manganese in the OH slag into an enriched intermediate slag, which is used as raw material for the production of ferro-manganese-niobium.

Hot metal from Baotou blast furnace contains about 0.08% of niobium and 1% of manganese. The openhearth slag accumulated at that steelplant also retains appreciable amounts of these metals. A process has been developed, using a small blast furnace and side-blown converter for collecting niobium and manganese in the OH slag into an enriched intermediate slag, which is used as raw material for the production of ferro-manganese-niobium. Methods were also experimentally studied for the direct extraction of niobium and manganese from the hot metal. It was found that by properly treating the hot metal in a converter, be it top-blown, side-blown or bottom-blown, at least 80% of the niobium and manganese is oxidized, producing a slag which is in effect an artificial niobiferous manganese ore, that can be used for making niobiferous ferromanganese especially suitable for the production of niobium micro-alloyed high-strength steel. A bottom-blown converter is preferable to the side-or top-blown in that less of the phosphorous will go into the slag, thus simplifying the letter's subsequent processing. A neutral lining (e. g. high alumina brick) would have the advantage of longer life, and higher Nb and Mn as well as lower P content in the slag produced. Large scale tests of a continuous spray extraction process pointed towards considerable potential advantages over the intermittent converter processes.

包钢高炉生产的铁水含铌约O.08%,锰约1%,积存的废平炉渣也含铌、锰。通过试验研究发展了一种用小高炉一转炉将平炉渣的铌和锰加以富集的方法,以及从包钢铁水直接提取铌锰渣的各种方法。结果证明,不论用顶吹、侧吹或底吹转炉,只要将吹炼温度保持在1350℃左右,铁水中铌和锰均至少80%都被氧化,形成一种实际上可看作是含铌人造锰矿的铌锰渣,可用以炼制适于生产含铌高强度低合金钢的铌锰铁。为了降低铌锰渣的磷含量,从而简化下步工序,用底吹转炉比侧吹或顶吹都较为有利。为了同一目的,同时也提高渣中铌和锰的品位和转炉炉衬的寿命,可采用中性炉衬一如高铝砖。试验了从铁水提铌锰渣的连续操作工艺,发现它有许多潜在优点。
