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。

The law how these factors influence the joint"s property was pointed out. A formula about the relationship between extrusion times and contamination remainder was founded. Main reason to bimetal"s inharmonic deformation was the difference of their mechanical property.
