             輕燒鎂球中二氧化硅含量要控制在一定的百分比,如果硅含量超標,將顯著降低鋼的塑性和韌性。硅能降低鋼的密度、熱導率和電導率。能促使鐵素體晶粒粗化,降低矯頑力。硅能促使鑄鋼中的柱狀晶成長,降低塑性。硅能降低鋼的焊接性能。因為與氧的結合能力硅比鐵強,在焊接時容易生成低熔點的硅酸鹽,增加熔渣和融化金屬的流動性,引起噴濺現象,影響焊接質量。所以輕燒鎂球中一定要嚴格控制硅的含量,避免煉鋼時作為原料帶入。

            The content of silicon dioxide in light-burned magnesium balls should be controlled to a certain percentage. If the silicon content exceeds the standard, the plasticity and toughness of steel will be significantly reduced. Silicon can reduce the density, thermal conductivity, and electrical conductivity of steel. Can promote the coarsening of ferrite grains and reduce the coercive force. Silicon can promote columnar crystal growth in cast steel and reduce plasticity. Silicon can reduce the welding performance of steel. Because silicon is stronger than iron in binding ability with oxygen, it is easy to generate low melting point silicate during welding, which increases the fluidity of molten slag and molten metal, causing spatter and affecting welding quality. Therefore, the content of silicon must be strictly controlled in light-burned magnesium balls to avoid being brought in as raw materials during steelmaking.
