Rail Free Steel Wire Rope Winch For Aluminum Billet Casting Machine

Rail-Free Steel Wire Rope Type Winch Aluminum Billet Casting Machine

Product introduction

The winch casting machine is a non rail steel wire rope type, and the supply includes the winch mechanism (drum, reducer, pulley, steel wire rope, etc.), caisson, wellhead frame, tilting mechanism, hydraulic cylinder, hydraulic system, and electrical control system.

The winch has a stroke greater than 6 meters and adopts a single drum with four steel wire ropes. The casting machine drum adopts

Made of welded seamless pipes with a diameter of 200, equipped with a 50 meter long multi strand all steel core steel wire rope specifically designed for lifting. The bolts used to adjust the length of the steel wire rope are stainless steel bolts. The maximum load-bearing capacity of the casting machine is 1 ton (at high water level). The motor power is 3.7kw.

FAQ 

1. What are the key points of daily inspection?

Aluminum liquid temperature/level, flow channel/filtration, crystallizer (water temperature/pressure/flow rate), casting speed/traction, and surface quality of cast rod.

2. What is the regular maintenance cycle?
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.
Every year: overhaul the furnace body (repair/reline the furnace lining); conduct a comprehensive inspection and maintenance of the casting machinery and electronic control system.

3. Safety precautions?
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.

4. The reason of the dimensions of the cast rods out of tolerance (ellipsoidal, bent, uneven diameter)?
Reasons: deformation/wear of the crystallizer, uneven cooling water, unstable casting speed, asynchronous traction machine, uneven base.
Solution:
Crystallizer: Regularly inspect the roundness/wear of the inner wall, and replace it promptly if it exceeds the tolerance; clean the scale from the water gaps to ensure uniform cooling.
Speed / Traction: Stabilize the casting speed, calibrate the synchronicity of the traction machine; ensure the base is level and reduce vibration.

5. The reason of cast rod porosity / shrinkage cavity (internal voids, poor density)?
Reasons: Excessively high pouring temperature, too fast casting speed, insufficient cooling, poor shrinkage compensation, and a wide solidification range of the alloy.
Solution:
Temperature / Speed: Reduce the pouring temperature, appropriately decrease the casting speed, and extend the solidification time.
Cooling: Enhance the cooling intensity of the crystallizer to ensure sufficient secondary cooling; optimize the water flow distribution in the crystallizer.
Shrinkage compensation: Design the runner reasonably, strengthen the riser for shrinkage compensation, and reduce shrinkage cavities.
