[0004] 1. In order to reduce the cost in the process of using rare earth element R for chemical oxygen and nitrogen removal, the remaining amount of element R is strictly stipulated at 0-0.3%, and its burning loss rate should be controlled within 50% (burning loss of R element in 201210592488.2 The amount is 5-100% atomic percentage. In the actual manufacturing process, the excessive burning loss not only increases the cost, but also fails to achieve the purpose of removing oxygen and nitrogen). Under the condition of this addition amount, it is controlled by a suitable smelting process And a variety of rare earth options can also obtain zirconium-based amorphous alloys with greater forming ability and better physical properties, but in this case the oxygen content control level is not good. During the reciprocating use, with the oxygen nitrogen As the content increases, the performance parameters
