Abstract

The invention provides a preparation method for a high-content aluminum-boron alloy, and relates to the technical field of alloy production. The preparation method comprises the following steps: (1) taking and putting 40-60kg of pure aluminum into a smelting furnace for heating the smelting furnace; (2) adding potassium fluoborate for making the potassium fluoborate to be in contact with pure aluminum; (3) using a mixer to mix; (4) mixing the added potassium fluoroaluminate with potassium fluotitanate, and continuously mixing; (5) scumming off; (6) heating a setting mould; (7) pouring a metalmixed solution in a molten state into the mould, and cooling and forming to obtain the aluminum-boron alloy. Pure aluminum is used to replace conventional aluminum alloy powder, so that purity of aluminum is improved; and a mechanical rotary blade type mixer is used to mix a mixture of the potassium fluoborate and the pure aluminum, so that the potassium fluoborate and the pure aluminum completelyreact; and potassium fluoroaluminate and potassium fluotitanate are beneficial for making content of boron of the obtained aluminum-boron alloy higher, so that high-content aluminum-boron alloy can be obtained. The preparation method is high in practicability.

Description

Technical field [0001] The invention relates to the technical field of alloy production, in particular to a method for manufacturing a high-content aluminum-boron alloy. Background technique [0002] An alloy is a mixture of two or more metals and metals or non-metals with metallic characteristics synthesized by a certain method. It is generally obtained by melting into a homogeneous liquid and solidifying. According to the number of constituent elements, it can be divided into binary alloy, ternary alloy and multi-element alloy. [0003] Aluminum-boron alloy is also a kind of alloy, mainly used for high-conductivity aluminum alloy, high corrosion resistance aluminum alloy, high thermal conductivity aluminum alloy intermediate alloy. [0004] At present, most of the manufacturers in my country use AlTi5B And AlB It is mainly produced, and the boron content is relatively low. The production of high-content aluminum-boron alloys is still blank. Summary of the invention [0005] The...
