How to use the trolley furnace specificallyPublished by：2022/8/2 Categories:News Viewed by: 5395 times The burner of the fuel heating trolley furnace should be installed along the tangent direction of the bath when using and repairing the trolley furnace. At regular intervals (such as weekly), the bath should be rotated by 30-40 degrees to prevent local overheating and burn through, thereby extending the lifespan of the bath. Seal the gap between the bath flange and the furnace panel with refractory cement or asbestos padding to prevent molten salt from flowing into the furnace. It is not advisable to use fuel to heat the nitrate furnace, in order to prevent explosions caused by the interaction between carbon black and nitrate after the furnace tube burns through. Salt discharge holes should be installed at the bottom of the trolley furnace to allow molten salt to be discharged in case of accidents. They should be plugged with appropriate materials during normal operations. The trolley furnace uses two thermocouples to separately measure the furnace temperature near the salt bath and heating elements.
When using toxic bath agents such as cyanide salts, lead, and alkali, strong ventilation equipment should be installed. The key skills for the application and repair of electrode salt bath furnaces are that newly purchased or repaired electrode salt bath furnaces should be baked using a resistance wire coil furnace, with segmented temperature rise and insulation to prevent cracking of the concrete bath. The exhaust equipment should be turned on during work, and the furnace opening should be covered when there is a power outage.
The furnace shell and transformer are grounded. The copper bar and electrode handle should have excellent contact. Check for electrical leakage and short circuits in the bath, electrodes, electrode handles, transformers, and water cooling equipment. Clean the sticky salt, oxide scale and other dirt in various parts of the furnace. The salt liquid level should be maintained at a certain height to ensure that the workpiece can be uniformly and quickly heated. Deoxygenation, slag removal, and sufficient new salt should be added in a timely manner.
