鋼水脱氧的好坏,对产品質量有很大影响。我們采用了用潮模砂做的砂型(如图1)做爐前檢查脫氧的方法。在鋼水还原末期,取出一勺鋼水注入砂型中做試块,如果鋼水脫氧良好,在泠却过程中試块表面要向下收縮成凹形如图2。如 The quality of molten steel has a great impact on product quality. We use tidal sand made of sand (Figure 1) to do before the furnace deoxidation method. At the end of the reduction of molten steel, remove a spoonful of molten steel into the sand to do the test block, if the molten steel deoxy well, in the process of cooling the test piece surface to shrink down into a concave shape in Figure 2.
