Abstract
The invention discloses a smelting method of a copper and magnesium intermediate alloy and belongs to the field of non-ferrous metals. The smelting method comprises the following steps: (1), preparing a covering agent; (2), putting magnesium in a crucible furnace to smelt, and covering the surface of the melt by using the covering agent; (3), preheating copper at a temperature of 500-600 DEG C; (4), adding preheated copper into molten magnesium in three batches; (5), continuously heating molten magnesium till copper blocks are fully melted; (6), stirring the melt till the melt is uniform in component and insulating for 4-5 hours; (7), forming the solution by pouring after removing slag. The method disclosed by the invention solves the problem that the yield of the intermediate alloy is relatively low as the covering agent is unreasonably prepared and short of operating method in the existing preparation method of copper and magnesium intermediate alloy, and has the advantages of simplicity, low cost and easiness in processing.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of method for the manufacture of copper magnesium master alloy.
Background technology
Copper and alloy thereof have excellent chemistry, physical and mechanical properties, solidity to corrosion in air, fresh water, seawater and non-oxidizable acids medium is good, thus Chang Zuowei functional materials and structured material, and being widely used in the fields such as aviation, shipbuilding, electrician, its consumption is only second to aluminium alloy in non-ferrous alloy material.
Copper alloy is in the process of smelting, and large multielement is all add in the mode of master alloy.Utilize the mode that master alloy adds, the melting loss of alloying element can be reduced on the one hand, thus realize the accurate control of alloy chemical composition; On the other hand, while reduction smelting temperature, also shorten smelting time, be conducive to the life-span of improving melting equipment, and save energy.
And for the manufacture of master alloy, conventional method has fusion process, reduction method, fused salt electrolysis process and powder method, although method is numerous, at present for the manufacture of copper magnesium master alloy, because insulating covering agent configuration requirement is higher, and make technology of preparing imperfection.
Summary of the invention
For existing copper magnesium master alloy in preparation process, because of insulating covering agent unreasonable allocation and working method shortcoming, and cause the problem that master alloy output capacity is lower, the invention provides a kind of melting method of copper magnesium master alloy, by reconfiguring insulating covering agent, and adjustment member working method, the output capacity of master alloy is improved.
For solving the problem, the present invention adopts following technical scheme.
A melting method for copper magnesium master alloy, comprises the following steps:
(1) preparation of insulating covering agent:
Insulating covering agent is by KCl, MgCl
2, BeCl
2, CaF
2composition, the mass percent of each component is: KCl:35%, MgCl
2: 35%, BeCl
2: 20%, CaF
2: 10%;
(2) put in crucible oven by magnesium and melt, and utilize insulating covering agent to be covered by bath surface, cladding thickness is 60-85mm;
(3) carry out preheating to copper, preheating temperature is 500-600 DEG C;
(4) copper after preheating is joined in magnesium liquid in three batches;
(5) heating magnesium liquid is continued, until copper billet melts completely;
(6) melt is stirred, until bath composition is even, insulation 4-5h;
(7) after slagging-off, solution casting is shaped.
Preferably, in described step (2), the cladding thickness of insulating covering agent is 70-80mm.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by reconfiguring insulating covering agent, and adjustment member working method, improve the output capacity of master alloy.
(2) the inventive method is simple, and cost is low, handling ease.
