摘要： A method for melting and reducing chrome ore, which comprises charging chrome ore and carbonaceous material, and blowing in oxygen gas under a pressure ranging from 1 to 600 Torr, while molten metal is being stirred by a stirring gas blown in. In this method, a reaction vessel capable of allowing top blowing and bottom blowing onto the molten metal and decreasing pressure within the vessel is employed. Chrome ore and carbonaceous material can be used in the form of lumps or powder. When powdered ore and material are used, they can be injected through a lance or a tuyere into the vessel.

摘要： Molten metal is put under pressure of up to 10 atmospheres in a covered ladle and a gas soluble in the metal is bubbled through the melt. Some gas goes into solution, while the remainder rises in bubbles and brings inclusions suspended in the molten metal up to the surface. Then the pressure is lowered, after which gas comes out of the solution in fine bubbles which also bring impurity inclusions up to the surface. In another method molten steel is refined at pressures not exceeding atmospheric pressure in a covered ladle equipped for evacuation and equipped for bubbling gas through the molten steel bath. Bubbling followed by pressure reduction can then be performed to form two stages of cleaning. Heat may be added for compensating the cooling effect of gas expansion. Instead of a closed ladle, an open ladle may be used, into which there can be dipped a chamber fitted for evacuation and having two large tubes at opposite sides of the chamber extending downwards to orifices that may be lowered into the molten metal in the ladle. The melt is then drawn up into the chamber by atmospheric pressure as the chamber is evacuated. Then bubbling may be performed in one connecting tube by injection of gas from the bottom of the ladle, or at a mid-level of the tube, to produce circulation of the molten metal up into the chamber and down through the other tube.
摘要翻译：在覆盖的钢包中将熔融金属置于高达10个大气压的压力下，溶解在金属中的气体通过熔体鼓泡。一些气体进入溶液，而其余的气体会上升，并使悬浮在熔融金属中的夹杂物直到表面。然后降低压力，之后，气体从微细气泡中排出，这也使杂质夹杂物直到表面。在另一种方法中，在装备用于抽空并且用于鼓泡气体通过钢水浴的装备的覆盖钢包中，将钢水在不超过大气压的压力下精炼。然后可以进行鼓泡，然后进行减压以形成两个阶段的清洁。可以添加热量来补偿气体膨胀的冷却效果。可以使用开放的钢包，而不需要一个开放的钢包，其中可以浸入一个适于抽真空的室，并且在室的相对侧有两个较大的管子向下延伸到可以放入钢包中的熔融金属的孔中。随着室被抽真空，熔体随后通过大气压被拉入腔室。然后可以在一个连接管中通过从钢包的底部注入气体或在管的中间层进行鼓泡，以产生熔融金属向上流入腔室并向下通过另一个管的循环。

摘要： A method for economically manufacturing an iron-boron-silicon alloy through simple steps, which comprises the steps of: adding a boron raw material and a carbonaceous reducing agent to a molten iron received in a vessel; blowing oxygen gas into the molten iron to reduce the boron raw material in the molten iron by means of the carbonaceous reducing agent to prepare a boron-containing molten iron; continuing the blowing of oxygen gas to decarburize the boron-containing molten iron until the carbon content in the boron-containing molten iron decreases to up to 0.2 wt. %; and adding at least one of silicon and ferrosilicon to the boron-containing molten iron while stirring the boron-containing molten iron, thereby manufacturing an iron-boron-silicon alloy.
