Brown corundum Furnace
Corundum smelting furnace overview:
Corundum is generally made of industrial alumina or bauxite after sintering or electric melting. When industrial alumina is electromelted, white corundum is obtained, and its Al2O3 content is greater than 98.5%; When bauxite is used as raw material, common corundum is obtained, and its Al2O3 content is 91~93%, and after treatment, the Al2O3 content is greater than 97%. When iron filings are added, brown corundum can be produced; When zircon or zirconia is added, zircon corundum is obtained. That is to say, corundum can be divided into sintered corundum and fused corundum two major varieties, and can be divided into white corundum, brown corundum, zirconium corundum, black corundum, chrome corundum and so on. White corundum can also be divided into ordinary fused corundum and low porosity or dense fused corundum. In amorphous refractories, the use of white corundum and brown corundum as refractory aggregate and powder has been more and more applied, and remarkable results have been achieved.
Brown corundum melting furnace process overview:
Equipment Overview:
1. The furnace cover is fixed, and the furnace cover is provided with 3 feeding ports, observation devices, dust removal ports and electrode holes. ;
2. Each phase uses a large section of internal water-cooled cable, compensator, wall through copper pipe, copper pipe conductive cross arm (trolley lift type) to form a space triangle arrangement of energy-saving short network. Three-phase impedance unbalance ≤4.5%. Water-cooled cable and water-cooled copper pipe section current carrying ≤4.5A/m㎡; The current carrying capacity of the copper bar section of the short network is less than 1.5A/m㎡.
3. Electrode lifting automatic regulator adopts full hydraulic proportional valve control automatic lifting regulator. The electrode lifting can be operated automatically and manually, and the electrode response time is less than 0.25S. Arc current setting range: 25%-130%, electrode response time: 0.15S.
4. The furnace body tilting, electrode lifting, electrode holding brake adopts hydraulic transmission, integrated block hydraulic valve;
5. The electrode holder adopts copper forging structure, stainless steel belt type disc spring clamping, hydraulic release, reliable use, long life.
6. The electrode automatic lifting regulator is controlled by Siemens S7PLC.
7. The electric furnace transformer adopts low-loss energy-saving transformer, which can be overloaded by 20% for a long time, on-load electric voltage regulation, strong oil-water cooling, transformer primary voltage 10KV, secondary voltage 170-380V. On-load electric voltage regulation, top out line mode, and equipped with perfect oil temperature and gas protection device.
8. The high voltage electrical control adopts KYN28 new switchgear, equipped with a special microcomputer protection device for electric furnace transformation, with a complete range of voltage, current, power and electrical measurement and relay protection, zinc oxide arrester to absorb operating overvoltage, and a simple rectifying power supply for switching.
9. The cooling water system has pressure and water temperature monitoring, sound and light alarm. In order to prevent power failure, the user needs to set up a high water tank.
10. Electric furnace parameters to implement industrial computer monitoring and management. Advanced and perfect upper computer, the central centralized control system to achieve the integration of the production line, intelligent, control, warning, protection system, to ensure the safe and reliable operation of the production line, can provide the possibility for the user's data management network (can be combined with the network communication module, through the mobile phone remote monitoring of the electric furnace operating status).
