Description

Technical Field

[0001] The utility model relates to the field of reduction furnace ejector pin sealing, in particular to an ejector pin sealing device for a sponge titanium reduction furnace. Background Art

[0002] Sponge-like titanium produced by metal thermal reduction. It is divided into five grades according to different purities. It is the main raw material for making industrial titanium alloys. Sponge titanium production is the basic link of the titanium industry. It is the raw material for titanium materials, titanium powder and other titanium components. Turn ilmenite into titanium tetrachloride, put it in a sealed stainless steel tank, fill it with argon, and react with metal magnesium to get "sponge titanium". This porous "sponge titanium" cannot be used directly. It must be melted into liquid in an electric furnace before it can be cast into titanium ingots. When processing sponge titanium, a reduction furnace is needed to perform thermal reduction. During the thermal reduction process, the ejector pin of the reduction furnace needs to be sealed. At present, when the ejector pin of the reduction furnace is sealed, most of them use manual lifting of the pressing plate to seal it. The sealing efficiency is slow, which is easy to cause heat leakage and reduce the reduction processing efficiency of sponge titanium. For this reason, we propose a sponge titanium reduction furnace ejector pin sealing device to solve the above problems. Utility Model Content
