Method of manufacturing a gas injection element |
摘要 |
A method for producing a weak resistance injection element for introducing gases into molten metals. The injection element includes an assembly of at least two high density refractory components. At least the upper high density refractory component is made by isostatic pressing of ceramic powders followed by a double heat treating process which are selected according to the liquid metal to be melted/refined in the metallurgical vessel where the injection element is going to operate.
