Description

Technical Field

[0001] The present invention belongs to the technical field of copper alloy processing, and particularly relates to an integrated device for copper alloy melt filtration and processing. Background Art

[0002] Copper alloy is an alloy composed of pure copper as the matrix and one or more other elements added. Pure copper is purplish red, also known as red copper. According to the alloy system classification, it can be divided into non-alloy copper and alloy copper. Non-alloy copper includes high-purity copper, tough copper, deoxidized copper, oxygen-free copper, etc. Conventionally, people call non-alloy copper purple copper or pure copper, also known as red copper, while other copper alloys belong to alloy copper. Alloy copper is divided into brass, bronze and cupronickel. Small alloy systems are divided within the large categories. An integrated device for copper alloy melt filtration and processing is required in the continuous melting and casting production line of high-performance copper alloy ingots and the preparation process of copper alloy precision castings for aerospace.

[0003] When high-strength and high-conductivity copper alloy is melted, oxidation slag and gas inclusions are easily generated. The traditional process uses multiple impurity removal processes, with low efficiency and large composition fluctuations. When adding micro-alloying elements, they are easily oxidized and burned out, and the addition method needs to be accurately controlled. When adding alloy elements manually, the burn-out rate is high, the single filtration efficiency is ≤70%, and the composition fluctuation is ±0.1wt%.

[0016] The technical effects achieved by the present invention are:

[0017] The copper alloy raw material is added into the smelting furnace body, and the heating component of the smelting furnace body is turned on to heat and melt the copper alloy raw material. A permanent magnet array is arranged at the bottom of the smelting furnace body, and the rotation is driven by a variable frequency motor (the speed is adjustable from 0 to 200 rpm) to generate a spiral magnetic field to force the melt to convect and promote the floating of inclusions. The high temperature resistant motor is turned on to drive the first mounting rod to rotate, and then drive the first blade, the second blade, the third blade, the fourth blade, the fifth blade and the sixth blade to rotate. The melt convection velocity is filled at the position away from the permanent magnet array in the smelting furnace body, and the number of auxiliary blades on the first blade, the second blade and the third blade is reduced in turn. With the power generated by the permanent magnet array, the melt flow velocity in the smelting furnace body is similar as a whole, so that the smelting of the copper alloy raw material is more uniform. The delivery pump is turned on to pass the Ar-N2 mixed gas in the gas storage tank through The L-shaped delivery pipe is transported to the annular jet ring, and the Ar-N2 mixed gas is sprayed into the smelting furnace body through multiple jet holes, generating micron-level bubbles to absorb hydrogen and oxygen impurities. A double-layer air lock structure is adopted to prevent air from entering. The servo-driven wire feeder automatically adjusts the wire feeding speed (0.1-5m / min) according to the melt temperature (monitoring accuracy ±2°C). The installation of the graphite baffle prolongs the contact time between the alloy wire and the melt, and improves the recovery rate to more than 95%. A PLC controller is installed on the spectrum detector, and the PLC controller is electrically connected to the servo-driven wire feeder and the frequency conversion motor. The spectrum monitoring probe detects the Cu, Cr, and Zr contents in real time at the outlet of the liquid outlet pipe, and the data is fed back to the PLC controller. When the Zr content is lower than the set value, the servo-driven wire feeder is automatically accelerated and the electromagnetic stirring intensity of the frequency conversion motor is enhanced. The composition fluctuation is controlled within ±0.03wt%;

[0018] The handle is turned, and the first rotating member and the second rotating member cooperate to open the furnace cover. The first driving motor can drive the rotating rod and the first gear to rotate, thereby driving the two third mounting plates to move toward each other, so that the third mounting plate is disengaged from the slot, thereby taking the second mounting plate and the plurality of fan blades out of the smelting furnace body, which is convenient for cleaning the waste slag in the smelting furnace body, turning on the refrigerator to transport the obtained cold air to the dispersion plate, turning on the third driving motor to drive the third gear to rotate, thereby driving the sliding plate and the dispersion plate to reciprocate in the horizontal direction, thereby evenly distributing the permanent magnet array. Evenly dissipate heat to increase the continuous working time of the permanent magnet array. The cooperation of the ventilation pump and the ventilation fan blades is conducive to improving the ventilation efficiency in the first mounting plate. Turn on the second drive motor to drive the second gear to rotate, and then drive the baffle plate to move, so that the liquid outlet pipe is opened. The ceramic foam filter layer is a gradient aperture filter plate (upper layer 10PPI→lower layer 20PPI), which intercepts oxide slag and unmelted metal particles. Sealed wire feeding + in-situ reaction, the recovery rate is increased by 10%, the three-stage purification system, the inclusion removal rate is ≥92%, and the closed-loop control achieves ±0.03wt% accuracy.
