Abstract
The invention discloses a smelting method for a cast copper alloy. The smelting method comprises the following steps: cleaning a crucible, and preparing and cleaning various smelting operation tools; weighing a pre-prepared refining and deteriorating refiner according to amount needed for treating copper liquor, placing into an oven, and roasting for 4-6 hours at 200-300 DEG C for later use; feeding into a furnace and melting, namely adding 0.5% of niobium, 3% of phosphor copper alloy, 0.6% of rare earth; and finally, quickly casting at 1165 DEG C within about 3-4 minutes after standing for 20 minutes, standing for 5-10 minutes, checking fracture, and slagging off after the fracture is qualified. The smelting method disclosed by the invention is a casting method which combines copper refining, deteriorating and refining into one step, so that mechanical performance, density and pressure resistance (eight water pressures) are improved; according to the method, a zinc element is not added, so that cost is lowered, and service life is prolonged by 5-6 years.
Description
Technical field
The present invention relates to a kind of alloy melting method, a kind of smelting copper alloy method that while specifically relating to smelting copper alloy, essence melting modifying-refining one step completes, more specifically Melting Technique of Casting Copper Alloy method.
Background technology
Alloy melting is the important step that ensures alloy internal soundness and cast properties, alloy smelting process is in the past the method that adopts charcoal to cover to add the rotten and phosphor-copper exhaust (or adding a small amount of zinc) of ternary alterant (salt kind solvent) mostly, be that I am the technique that smelting copper alloy follows always, its technological principle is that charcoal removes refining the oxygen in copper in the process that covers burning.
Summary of the invention
Object of the present invention, be to provide a kind of by the castmethod of copper refining, rotten, the synthetic step of refinement three steps, to improve the mechanical property of copper alloy, density and compressive resistance (8 hydraulic pressure) thus reduce costs the work-ing life that extends product.
The technical scheme that the present invention adopted is for achieving the above object: Melting Technique of Casting Copper Alloy method, comprises the steps:
1) crucible is cleaned out, prepared smelting operation various tool, clean out;
2) the refinement and denaturation fining agent preparing is in advance weighed by the needs of processing copper liquid measure, put into baking oven, under 200-300 degree, toast 4-6 hour, for subsequent use;
3) shove charge fusing: first pack charcoal into, it adds the ratio of 1 kilogram of charcoal according to every 100 kilograms of copper liquid, reinstalls returns, then adds 300 kilograms of fine copper plates; If be full electrolytic copper, refining agent is increased to every 100 kilograms of copper, add 1.3 kilograms of refinement and denaturation fining agents, start melting, when copper liquid temperature reaches after 1200 degree, add subsequently 0.8% the niobium that accounts for above-mentioned substance total mass, 3.5% phosphor copper, 1% rare earth, after changing clearly, copper liquid temperature reaches after 1200 degree, adds the refinement and denaturation fining agent of drying to process 15-25 minute;
4) add again and account for the 3rd) 0.5% niobium of step total mass, 3% phosphor copper, 0.6% rare earth; Finally after static 20 minutes, in the time that 1165 spend, cast fast; Approximately within 3-4 minute, complete;
5) static 5-10 minute, checks fracture, skims after qualified.
The aforesaid smelting copper alloy method of making, is characterized in that: in described phosphor copper, phosphorus content is 7%.
The melting method of aforesaid cast copper alloy, is characterized in that: described refinement and denaturation fining agent is red copper refining agent, and the weight ratio of itself and copper is 1: 100.
The melting method of aforesaid cast copper alloy, is characterized in that: described returns is the offal of the product of last refining.
The present invention is the castmethod of copper refining, rotten, the synthetic step of refinement three steps, to improve the mechanical property of copper alloy, and density and compressive resistance (8 hydraulic pressure); The method does not add zinc element, reduces costs, and increases 5-6 work-ing life.
