Water cooling device and method for indium casting

Abstract

The invention relates to a water cooling device for indium casting. The device comprises an elevated tank, a lower tank, a plurality of cooling discs and a plurality of cooling water collecting tanks,the elevated tank is provided with a cooling water inlet, indium is cast and cooled in the cooling discs, and the cooling water collecting tanks are in one-to-one correspondence to the cooling discsand are positioned below the cooling discs. The elevated tank conveys low-temperature cooling water into each cooling disc through a pipeline by using gravity or a centrifugal pump, the cooling discscollect the cooling water into the cooling water collecting tanks through holes in the bottoms of the discs, the cooling water collecting tanks convey the cooling water to the lower tank through a pipeline, and the lower tank conveys the cooling water to the elevated tank through the centrifugal pump. According to the cooling device and method, an automatic circulating water cooling manner is adopted for casting an indium ingot, the indium ingot can be rapidly cooled, compared with a cooling manner of natural cooling in the prior art, the purity of the indium ingot is guaranteed while the production efficiency is improved, and the indium ingot obtained after demolding is smooth in appearance and free of undesirable phenomena such as holes, shrinkage cavities and cracks.

Description

technical field [0001] The invention relates to the field of high-purity scattered metal preparation, in particular to a water cooling device and method for indium casting. Background technique [0002] Indium is an important scattered metal. Because of its unique and excellent physical and chemical properties, it is widely used in the fields of electronic computers, energy, electronics, optoelectronics, semiconductors, national defense, and aerospace. Metal indium ingots are mainly used to produce ITO targets, special solders for integrated circuits, high-performance alloys, etc. According to the indium standard YS / T257-1998, the purity of indium ingots obtained by casting must reach more than 99%, and the requirements for the casting production line are very strict . Most of the current indium ingot production enterprises still use natural cooling, which not only has low production efficiency, but also has a low pass rate of cast indium ingot purity, large weight error an...

AI Technical Summary

Problems solved by technology

Most of the current indium ingot production enterprises still use natural cooling, which not only has low production efficiency, but also has a low purity pass rate of cast indium ingots, and the weight error of each ingot is large and poor in consistency, which cannot meet subsequent production requirements.
