Abstract
The invention discloses a secondary smelting method of tin bronze and belongs to the field of non-ferrous metals. The secondary smelting method comprises the following steps: (1) preparing components of tin bronze; (2) putting copper in a preheated crucible and quickly melting copper under a micro-oxidizing atmosphere; (3) after melting, heating to 1150 DEG C and adding 50% of phosphor copper in dosage; (4) after deoxidization, adding preheated foundry returns and stirring; (5) adding preheated Zn at 1100-1150 DEG C, then adding Sn and Pb and finally adding the rest of phosphor copper and carefully stirring and deoxidizing; (6) sampling at 1100-1150 DEG C for furnace-front detection; (7) discharging and pouring. The secondary smelting method disclosed by the invention solves the problem that in the existing manufacturing process of tin bronze, the quality is defective as the smelting method is improper, and has the advantages of high 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 tinbronze.
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.
Tinbronze has higher mechanical property, wear resisting property and solidity to corrosion, and Cutting free is processed, and soldering and good welding performance, shrinkage coefficient is little, nonmagnetic.Can be used as preparing the coatings such as bronze bushing, axle sleeve, magneto-resistive element.Because it has higher intensity, solidity to corrosion and excellent castability, be widely used in for a long time in each industrial sector.But in the use procedure of tinbronze, usually there is the problem that its quality is short of.
Summary of the invention
For existing tinbronze in the fabrication process, because smelting process is improper, and the problem causing quality to be short of, the invention provides a kind of secondary smelting method of tinbronze, 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 secondary smelting method for tinbronze, comprises the following steps:
(1) preparation of each component of tinbronze:
The mass percent of each component of tinbronze is: Sn:6.6%, Zn:6.4%, Pb:3%, all the other are Cu;
(2) copper is loaded in preheated crucible, rapid melting under micro-oxidizing atmosphere;
(3), after fusing, be heated to 1150 DEG C, add the phosphor-copper of a half-value dose, the total mass of phosphor-copper accounts for the 0.5-0.8% of alloy solution total mass, and carries out stirring deoxidation;
(4) add the foundry returns of preheating after deoxidation, and stir;
(5) add the Zn of preheating at 1100-1150 DEG C, then add Sn and Pb, finally add remaining phosphor-copper, and carefully stir deoxidation;
(6) 1100-1150 DEG C of sampling, stokehold detection is carried out;
(7) to come out of the stove cast.
Preferably, in described step (3), the total mass of phosphor-copper accounts for 0.7% of alloy solution total mass.
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.
embodiment 1
