活性石灰是钢铁工业的基本原料，它作为炼钢的造渣剂，具有缩短冶炼时间、提高钢水纯净度及收得率、降低石灰及萤石消耗、提高转炉炉衬寿命等优点，还可以应用于钢水精练过程。

During the actual production, that the oxygen contamination from the crucible material by heat composition increases the oxygen content of molten steel will result in melting losses of the alloys in the molten steel, and will results in more heavier melting losses of the alloys, incontrollable exact chemical content of molten steel, increment of oxide inclusions and bad processability and serviceability, especially in the high strength(σb≥1600MPa) steels and alloys with special performance used in aerospace industry, manufacturing industry for precision instruments and meters, military industry, nuclear industry etc. because these steels usually have a high content of some active alloys such as Ti, V, Nb, Al, RE, etc. and a nearly zero content of dissolved oxygen.

实际生产中，如果炉衬热分解向钢液供氧，势必会造成钢液中合金元素的烧损，尤其是在航空航天、精密仪器仪表制造、军工及核工业部门使用的某些具有特殊性能的高强度(抗拉强度σb≥1600MPa)合金或钢材，因它们通常需要具有较高的活泼合金元素(如Ti、V、Nb、Al、RE等)含量，且钢中溶解氧含量接近于零，炉衬热分解供氧将造成这些合金元素的大量烧损，其结果是钢液化学成分难以精确控制，并增加了氧化物夹杂含量，恶化了钢的加工和使用性能。

MgO-C brick has a good erosion resistance but Al〓O〓-C brick is better. Corrosion mechanism for refractory without carbon is that FeO and oxides of molten slag take place chemical reaction with constituents of refractory and forming low fusing point compounds to be dissolved in molten slag. For those refractory containing graphite carbon is to be decarburized in advance and to form decarburizing layer and metamorphosis layer. The subsequent corrosion is decarburizing and taking chemical reaction to form low fusing point compounds and dissolved in molten slag at the same time.

铁浴中硅和钛的扩散是影响铁浴及熔渣与耐火材料作用的重要因素，耐火材料中添加的TiO〓和SiC受熔渣氧化和侵蚀，将被部分还原形成Si，Ti向铁浴中扩散，Si、Ti在铁浴中的扩散研究结果是： D〓=1.84×10〓exp（－5988.7/T） cm〓/S E〓=49766 J/mol D〓=7.76×10〓exp（－53225.5/T） cm〓/S E〓=442304 J/mol 铁浴式熔融还原熔体对粘土砖，高铝砖，镁砖的侵蚀速度很高，镁碳砖抗侵蚀能力比前几种耐火材料强，但不如铝碳砖；对不含碳耐火材料在熔体中的侵蚀是熔渣中FeO及其它氧化物与耐火材料组分的化学反应形成低熔点物熔蚀进入渣相，产生损毁。

Superimposing rotating magnetic field could reduce the total oxygen concentration of molten steel, in the situation of 80~120 r/min, the removal efficiency of total oxygen could be reached to 70% for molten carbon steel and 38% for molten stainless steel.

旋转磁场的施加使钢液中全氧含量迅速降低，在80~120r/min的转速下，碳钢可以获得约70％、不锈钢可以获得38％以上的全氧含量去除效率。

The flow of molten metal are the forefront of the lost foam pyrolysis products, it will happen with the liquid metal reflect and affect the quality of metal liquid, if the liquid metal filling process in pyrolysis products should not rule out smoothly, it is easy to cause stomatal , Cockle, by defects such as carbon.

金属液的流动前沿是热解的消失模产物，它会与金属液发生反映并影响到金属液质量，如果金属液充型过程中热解产物不能顺利排除，就容易引起气孔、皱皮、增碳等缺陷。
