Product Description 40KG Medium-Frequency Induction Iron Melting FurnaceI. Equipment OverviewDesigned for university laboratories, research institutions, and precision material R&D scenarios, the 20kg medium-frequency copper melting furnace achieves efficient melting and composition control of red copper, brass, bronze, and other copper alloys based on electromagnetic induction heating principles. Integrated with an intelligent temperature control system and electromagnetic stirring function, the equipment meets the strict requirements for melting precision in new material R&D, microstructure research, and other experiments, occupying less than 1 square meter to fit compact laboratory layouts II. Core Working Principles1. Medium-frequency Induction Heating MechanismA medium-frequency power supply (frequency range 1-20kHz) converts three-phase 380V power frequency electricity into alternating current, which is input into a copper induction coil. The alternating magnetic field generated by the coil excites eddy currents in the copper charge, using the resistance heating effect of copper to achieve temperature rise (thermal efficiency ≥85%). The cold furnace melting time from room temperature to 1100oC is approximately 30-40 minutes.2. Electromagnetic Stirring TechnologyLorentz forces generated by the medium-frequency magnetic field drive directional flow of the copper melt, with stirring intensity automatically adjusted with frequency to ensure uniform distribution of alloy elements. Test data shows that in the melting of Cu-30Zn brass, electromagnetic stirring can reduce the zinc element segregation rate from 12% to below 3%.III.

By adjusting the electromagnetic stirring intensity (5-15kHz), the dendrite spacing was successfully refined from 50μm to 20μm, with related achievements published in Materials Science and Engineering A.2. Cultural Relics Restoration FieldUsed for reducing melting of ancient bronze ware (such as Shang and Zhou Dynasty Cu-Sn-Pb alloys). Temperature control accuracy ensures Sn element loss rate ≤1.5%, meeting the composition matching requirements for cultural relic imitation.3. Electronic Packaging MaterialsPrepares high thermal conductivity copper-silver alloy (Cu-10Ag). Precise temperature control (±2oC) controls Ag phase precipitation, enabling the material to achieve a thermal conductivity of 380W/(m·K), suitable for R&D of high-power chip heat dissipation substrates.VII. Operation and Maintenance Guidelines1. Standard Operation ProcessPlace a graphite crucible (diameter 200mm×height 300mm) in the furnaceLoad the charge, close the furnace cover, and connect cooling water (pressure 0.15-0.2MPa)Input process parameters on the touch screen (e.g., brass melting: heating rate 10oC/min to 920oC, holding for 15min)Start the automatic program, and the system real-time displays temperature curves and power output2. Maintenance Key PointsWeekly inspection: Check if the induction coil waterway is scaled (deionized water is recommended)Monthly maintenance: Inspect furnace lining refractory materials for cracks (repair if exceeding 2mm)Annual calibration: Calibrate the accuracy of the temperature control meter (traceable to national standards)VIII.
