Rail Free Steel Wire Rope Winch For Aluminum Billet Casting Machine

Daily: Clean the slag from the furnace mouth/flow channel; inspect the burner, ignition system, and seals.

Weekly: Verify thermocouples/temperature control instruments; clean the scale in the water gap of the crystallizer; check the integrity of the filter plate.

Monthly: Conduct a comprehensive inspection of the lining thickness/cracks; calibrate the casting speed and traction synchronization; replace aged sealing rings/gaskets.

Annually: Overhaul the furnace body (repair/reline the furnace lining); conduct a comprehensive inspection and maintenance of the casting machinery and electronic control system.

High temperature protection: Wear high temperature resistant clothing, protective face masks, and heat-insulating gloves to avoid burns.

Explosion protection: Leakage is strictly prohibited in gas furnaces, and regular leak detection is required; moist materials are prohibited inside the furnace to prevent explosions caused by water encountering aluminum liquid.

Emergency response: Equip with dry powder fire extinguishers and dry sand.

Reasons: Deformation/wear of the crystallizer, uneven cooling water, unstable casting speed, asynchronous traction machine, uneven base.

Solutions:

• Crystallizer: Regularly inspect the roundness/wear of the inner wall, and replace promptly if exceeding tolerance; clean scale from water gaps to ensure uniform cooling.
• Speed/Traction: Stabilize casting speed, calibrate synchronicity of traction machine; ensure base is level and reduce vibration.

Reasons: Excessively high pouring temperature, too fast casting speed, insufficient cooling, poor shrinkage compensation, and wide solidification range of the alloy.

Solutions:

• Temperature/Speed: Reduce pouring temperature, appropriately decrease casting speed, and extend solidification time.
• Cooling: Enhance cooling intensity of crystallizer to ensure sufficient secondary cooling; optimize water flow distribution in crystallizer.
• Shrinkage compensation: Design runner reasonably, strengthen riser for shrinkage compensation, and reduce shrinkage cavities.
