Abstract
The invention discloses a method for preparing aluminum bronze and belongs to the field of nonferrous metals. The method comprises the following steps: (1) preparing all ingredients of aluminum bronze; (2) loading copper to a preheated crucible, and enabling the copper to be rapidly melted; (3) further heating, adding phosphor copper and carefully stirring, so as to carry out deoxidation treatment; (4) adding preheated ferroaluminum intermediate alloy; (5) heating to the temperature of 1200 DEG C, adding a refining agent, of which the mass is 3-5% the total mass of a furnace charge, and stirring to deslag; (6) carrying out stokehole detection and test; (7) immediately drawing the charge if various detection is qualified after refining is completed, scumming, and spraying cryolite, of which the mass is 0.2-0.3% the total mass of the furnace charge; (8) casting. According to the method, the problem of the existing aluminum bronze that the quality is defective due to improper smelting methods during preparation is solved; the method has the advantages of simple method, 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 xantal.
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.
Xantal has higher intensity and good wear resistance, and be usually used in the higher screw rod of strength ratio, nut, copper sheathing, wear ring etc., its most outstanding feature is good wear resistance, and heat-treatable strengthened, and its strength ratio tinbronze is high, and high temperature oxidation resistance is also better.But in the use procedure of xantal, usually there is the problem that its quality is short of.
Summary of the invention
For existing xantal in the fabrication process, because smelting process is improper, and the problem causing quality to be short of, the invention provides a kind of manufacture method of xantal, by changing its smelting technology, its quality being improved, reach the object improving its quality.
For solving the problem, the present invention adopts following technical scheme.
A manufacture method for xantal, comprises the following steps:
(1) preparation of each component of xantal:
The mass percent of each component of xantal is: Al:9.5%, Fe:4%, all the other are Cu;
(2) copper is encased in the crucible of preheating, makes its rapid melting;
(3) continue heating, when temperature reaches 1100-1250 DEG C, add phosphor-copper and carefully stir, carry out deoxidation treatment, the percentage ratio that the phosphor-copper added accounts for furnace charge total mass is 0.5-0.7%;
(4) add the ferro-aluminum master alloy of preheating, pour into foundry returns after dissolving completely, and stir;
(5) temperature is risen to 1200 DEG C, add the refining agent of furnace charge total mass 3-5%, stir slagging-off;
(6) stokehold detection experiment, if air content is too high, then with the chloride dehydrate zinc refinery by de-gassing of bell jar press-in furnace charge total mass 0.2-0.5%;
(7) after refining completes, every detection is qualified, comes out of the stove at once, except removing dross, and is sprinkled into the sodium aluminum fluoride of furnace charge total mass 0.2-0.3%;
(8) pour into a mould.
Preferably, in described step (3), the percentage ratio that the phosphor-copper added accounts for furnace charge total mass is 0.6%.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention is by changing its smelting technology, and its quality is improved.
(2) the inventive method is simple, and cost is low, handling ease.
Embodiment
Describe the present invention below in conjunction with embodiment.
