Intelligent control of high-temperature resistance furnaceScope of application: Equipment specially developed for the sintering, melting, analysis, and production of ceramics, metallurgy, electronics, glass, chemical engineering, machinery, refractory materials, new materials development, special materials, building materials, metals, non metals, and other chemical and physical materials in laboratories and industrial and mining enterprises of higher education institutions and research institutes.
All furnace lining materials are made of vacuum formed high-purity alumina fiber lightweight board material, which has high operating temperature, low heat storage capacity, no cracks, no slag falling, and good insulation performance (energy-saving effect is more than 60% of old-fashioned electric furnaces). The structure is reasonable, and the inner and outer double-layer furnace sleeves can greatly shorten the testing cycle.
Core points of daily maintenance:
Maintenance after each experiment:
Furnace cleaning: When the furnace temperature drops below 200 ℃, use a soft bristled brush to clean the residual powder and ash inside the sample, and prohibit scratching with metal tools. If there are stubborn attachments, use a clean cloth dipped in a small amount of anhydrous ethanol to wipe, let it dry naturally, and then close the furnace door.
Maintenance of furnace door and sealing surface: Use a dust-free cloth to wipe the inside of the furnace door and sealing gasket, remove oil stains and powder residues, and keep the sealing surface dry and clean; Check if the sealing gasket is flat, and promptly tidy up any wrinkles.
Appearance and environmental cleaning: Wipe the dust off the furnace shell to ensure that the ventilation openings and heat sinks are not blocked; Clean up debris around the equipment and maintain a dry and ventilated environment.
Regular weekly inspections:
Heating element inspection: Observe whether the heating element is broken, deformed, oxidized or blackened. If local damage or loose wiring terminals are found, tighten or mark them for replacement in a timely manner.
Circuit and wiring inspection: Check whether the power cord and thermocouple connection wire are damaged or aged, whether the plug and socket contact is good, and whether the grounding circuit is firm (grounding resistance ≤ 4 Ω).
Preliminary verification of temperature control system: Observe whether the temperature controller display is stable, without jumping or garbled characters, and whether the heating indicator light switches normally when heating up.
