Reducing furnace for preparing sponge hafnium

Abstract

The invention discloses a reducing furnace for preparing sponge hafnium. The reducing furnace comprises a hafnium tetrachloride subliming furnace, a magnesium ingot melting furnace and a communicatingpipe, wherein the communicating pipe communicates with the hafnium tetrachloride subliming furnace and the magnesium ingot melting furnace; the magnesium ingot melting furnace is provided with a lifting feeding pipe and a temperature control system; the magnesium ingot melting furnace comprises a furnace body and a furnace lid; the lifting feeding pipe is arranged on the furnace lid and is positioned in the magnesium ingot melting furnace; the communicating pipe communicates with the magnesium ingot melting furnace through the lifting heating pipe; the outlet of the lifting feeding pipe can move in the magnesium ingot melting furnace up and down; and the temperature control system can control the temperature in the magnesium ingot melting furnace to be less than the preset temperature. Therefore, the reducing furnace can improve the reducing efficiency, can prevent generation of low-price hafnium black powder to increase the product recovery rate, prevents the problem that the densityof the sponge hafnium product is excessively high and facilitates later crushing of sponge hafnium to increase the yield.

AI Technical Summary

Benefits of technology

This patented technology allows for efficient production of metal from melted metals without generating harmful waste or pollution during processing. It involves adding an elevated tube called a feeder with two ends: one end being connected to a source of electricity (the power supply) while another end connects to a reactor containing magnetic induction coils. When the material inside this device becomes hot enough to dissolve solidified metal, its surface falls down onto these inductors causing them to produce electrical current through their own resistance wire. By controlling how much energy flows across each component, such as the voltage applied to the wires, the amount of oxygen needed may also increase. Additionally, there are systems used to monitor temperatures at certain points along the process where the materials enter the fusion chamber. These monitoring devices help prevent damage caused by excessive pressure on the equipment' components like pipes and valving elements. Overall, this innovation helps optimize the efficiency and quality of producing highly pure iron products efficiently.

Problems solved by technology

This patents describes different methods for producing zirconia (Zr) hollow fibers called sponges made up mostly of zircite crystal grains. These can be useful because they have many applications such as use as fuel rods in atomic reactor systems. However, these existing processes produce unwanted impurities like iron, manganese, calcium, etc., making them challenging to recover products properly after being produced.
