Embodiment Construction

[0020] The chemical composition of the torpedo battery anode magnesium alloy is Mg-1.2-1.4wt%, Hg-0.5-0.7wt%, Ga-0.02wt%Ce. The batching of the alloy must consider the consumption of the melting process, and the burning loss is increased when the batching is easy to burn. The smelting adopts special technology to ensure the safety and environmental protection of the smelting process, and the composition of the alloy liquid is accurate.

[0021] The smelted magnesium alloy liquid is led from the crucible to the metal liquid distribution nozzle in front of the casting and rolling machine. The molten metal distribution nozzle is a refractory material with excellent thermal insulation properties, combined with an inorganic binder, the thickness of the flow channel of the molten metal is 20 mm, which can keep the molten metal flowing smoothly for a long time. The thin strip is directly introduced from the liquid metal into the internal water-cooled steel roll that rotates horizont...

Abstract

The technology of rolling a magnesium alloy anode plate of a military torpedo battery aims to obtain a magnesium alloy anode with high potential, high specific energy, high specific power and good storage status and operative mode. A thin magnesium alloy anode plate blank of the torpedo battery without gravity segregation is prepared by directly cooling a liquid metal and immediately applying plastic deformation with a high deformation degree. The finish rolling of the thin rolled cast plate blank adopts the rolling technology of cold-rolling of a heat roller under high pressure for the production of fine crystalline magnesium alloy plates and strips, and then the thin rolled cast plate blank is subjected to heat treatment under control to form the finished magnesium alloy plate with crystalline grains less than 10 micrometers. The production method has the advantages of low cost and short process flow; and the product quality of the magnesium alloy anode plate of the torpedo battery is high.

Description

technical field [0001] The invention relates to a production technology of a torpedo battery anode magnesium alloy plate, in particular to a rolling technology of a special magnesium alloy thin plate. Background technique: [0002] The battery is the main component of the power plant on an electric torpedo, providing energy for the propulsion motors. According to the use of the torpedo power unit, the torpedo battery should meet the following requirements: high specific energy, high specific power, long service life, low price, and convenient use and maintenance. The key to the development of electric powered torpedoes is to improve battery performance and reduce costs. Currently used for electric torpedo power batteries include: lead-acid batteries, cadmium-nickel batteries, silver-zinc batteries, primary silver-zinc batteries, magnesium / cuprous chloride torpedo batteries and magnesium / silver oxide batteries and other series. Magnesium has a high voltage, can work with hi...
