The experimental results indicated that the longer the po uring intervallic time of the two kinds of molten metal and the higher the heigh t of the molten iron to pour into the tip of dipper teeth , the narrower its tran sitional zone will be, on the contrary, the wider its transitional zone will be.

用不同粘度的流体通过水力模拟的方法近似地描述了双金属斗齿过渡区的混合状态。试验结果表明：两种液体浇注的间隔时间越长，先浇入的铁液液面越高，过渡区越窄；反之，过渡区越宽。生产中为了保证过渡区双金属的结合质量，应控制较高的铁液液面高度及一定的双液间隔时间

The main reasons are: the reaction+=Fe+CO also occur during molten iron drop passing final slag, the slag has lowlevel of FeO ,but it still has strong decarburizing capability. In addition, during molten irondrop passing final slag, the dynamic conditions of decarburizing reaction is well, it makethe carbon content of liquid iron reduce.

主要是因为铁滴穿过终渣时也发生+=Fe+CO 反应，此时渣中含量虽少，脱碳反应的动力学条件很好，具有较强的脱碳能力。

The treating process of blowing O_2、 N_2 Ar into molten cast iron and the dynamics and thermodynamics of the blowing process are studied. The effects of gas composite, blowing intensity, blowing form and molten iron temperature on molten iron composition and casting quality are analysed. And molten pig iron of the blast furnace is blown in 3t ladle.

用O_2、N_2、Ar气体对铁水进行吹炼处理，分析了吹炼处理的热力学与动力学原理，研究了吹炼处理的气体组成、吹气强度、吹气方式以及铁水温度对铁水成分与铸件质量的影响，并在3t铁水包中对高炉铁水直接进行吹炼处理。

Of raw materials to make ALE Series Stroke Stop and Stroke Switch use of carbon steel, ordinary gray cast iron or ductile iron back to BURDEN; reduce the liquid iron in the alloy elements such as Cr, Mn and other content, reducing its molten iron-containing gas; before the next core sand core all the overhead brush paint and the storage period to prevent the sand core to absorb moisture; in rainy days or high humidity of the season, the next best to use torch to the former core cavity, the surface of sand core baking again, in order to reduce sand-fat content; high-temperature casting a small valve in order to facilitate their own exhaust and the reduction of molten iron casting slag produced.

6原料尽量使用碳钢、普通灰铸铁或球墨铸铁回炉料；降低铁液中的合金元素如Cr、Mn等含量，减少铁液自身含气量；将下芯前的砂芯全部架空刷涂料且限期存放，以防砂芯吸潮；在阴雨天或湿度较大的季节，下芯前最好用喷灯将型腔、砂芯表面烘烤一遍，以减少砂型发气量；采用高温浇注小阀门，以利于铁液自身排气和减少铸渣产生。

The 120m3 BF foundation temperature is reduced from 950℃ to below 700℃ and the furnace life campaign is prolonged for more than 2 years by taking furnace maintenance measures such as batching schreyerite in burdens to deposit Tion hearth bottom to form a steady protective layer and make molten iron liquidity slower to slowdown the erosion on bottom, drilling holes to lay water-cooling pipes in heat resistant foundation to heighten the 1150℃ isothermal line of molten iron to make frozen metal layer thicker.
