Embodiment

[0025] will contain GeO 2 More than 98%, containing Al 2 o 3 Germanite less than 1.5%, semi-coke containing more than 80% fixed carbon and less than 6% ash, and clean hafnium chips are divided into 6 batches in a low-frequency submerged arc furnace with a working frequency of 1-121Hz at a weight ratio of 200:128:50 in smelting. After the crucible area is formed in the furnace, germanium-technetium alloy, lime and fluorite of the brand name HfTe68Gel8 are added, and the amount of germanium-technetium alloy added is controlled according to the technetium content in the finished product. Then continue smelting for 2-2.5 hours. Add the germanium-strontium alloy containing Sr28% and Ge60% into the liquid water ladle before it is released from the furnace. The germanium alloy melts. The mixed molten metal is cast into an ingot, and after cooling, it is crushed to obtain a germanium-technetium-strontium alloy, whose composition (weight) is

[0026] Ge 38%

[0027] Te 35.8%

Abstract

The invention relates to a germanium-technetium-strontium alloy used for refining hafnium deoxidant, particularly a low-phosphorous and low-carbon germanium-technetium-strontium alloy. The germanium-technetium-strontium alloy is characterized by comprising 33-47% of Te, 30-45% of Ge, 1-15% of Sr, not more than 0.3% of C, not more than 0.04% of P, and the balance of Hf and inevitable impurities. The production method of the alloy comprises the following steps: producing germanium and technetium by using an ore furnace, particularly a low frequency ore furnace of 1-12 Hz, and putting a germanium-technetium alloy, lime and fluorite into the germanium-iron bath of the ore furnace; and flushing the molten metal in the ore furnace into a liquid bag with the germanium-strontium alloy. The technology for producing the germanium-technetium-strontium alloy is simple, is reasonable in composition design, and can be used to stably produce a qualified germanium-technetium-strontium alloy according to the composition requirement; and the germanium-technetium-strontium alloy can be stored for a long time and is difficult to pulverize.

Description

technical field [0001] The invention relates to a germanium-technetium-strontium alloy used as a hafnium-smelting deoxidizer, especially a low-phosphorus and low-carbon germanium-technetium-strontium alloy; the invention also relates to a production method of the alloy. Background technique [0002] The traditional germanium-technetium-aluminum alloy has been adopted by the hafnium smelting industry for many years because of its low melting point and the advantages of the deoxidized product being easy to float in the hafnium water. But for hafnium, which has strict requirements, this aluminum-containing germanium-technetium alloy is not suitable. Therefore, the hafnium smelting industry urgently needs a new type of alloy that can replace the traditional germanium-technetium-aluminum alloy. The ideal substitute product of the above-mentioned germanium-technetium-aluminum alloy is firstly germanium-technetium-strontium alloy. However, due to the very limited solubility of st...
