Abstract
A thermite process for producing a pure metal or alloy by charging a reactor furnace with a mixture primarily containing a powdered metallic oxide and a reducing agent such as powdered aluminum, wherein a batch of the mixture of the starting materials is divided into a plurality of loading lots. The amount of heat generated by each of the loading lots of the starting materials is so regulated that the amount of heat generated by each loading lot differs from the amount of heat generated by other loading lots and the loading lots are sequentially arranged. The lots are loaded into a furnace to form layers for thermite reaction in an ascending order of heat generation.
Claims6
A thermite process for producing a pure metal or alloy metal by a thermite reaction after charging a reactor furnace with a mixture of a powdered metallic oxide and a reducing agent, the process comprising the steps of:
- dividing a batch of the mixture into a plurality of loading lots such that an amount of heat generated by each loading lot of the plurality of loading lots is regulated to produce a different predetermined amount of heat for each respective loading lot, and
- loading each loading lot sequentially into the reactor furnace for thermite reaction in an ascending order of heat generation.
