Abstract
A treatment agent and method to introduce magnesium into ferrous material. The treatment agent includes a mixture of high melting temperature particles and magnesium particles. The content of high melting temperature particles in the particle mixture is present in an effective amount to inhibit the complete conversion of the magnesium particles into molten magnesium prior to the magnesium particles entering the ferrous material. The method describes the efficient treatment of molten ferrous material with these particles.
Claims77
A treatment agent for a molten ferrous material comprising a mixture of high melting temperature particles and magnesium particles, said high melting metal temperature particles content of said mixture present in an effective amount to inhibit the conversion of said magnesium particles into molten magnesium prior to said magnesium particles entering said molten ferrous material.
A method of alloying a ferrous material comprising:
- a) melting a ferrous material;
- b) inserting a lance into the molten ferrous material until the end of the lance is at least partially submerged beneath the surface of the molten ferrous material;
- c) injecting particles though said lance and into said molten ferrous material to alter the composition of the molten ferrous material, said particles having a composition which at least partially inhibits the melting of said particles prior to said particles entering said molten ferrous material thereby reducing the occurrence of plugging the end of said lance by melted particles.
