Rotary Flux Injector for Molten Aluminium Refining

1. EQUIPMENT FEATURES

 Rack

• The rack is made of rectangular tubes and welded steel plates. The frame structure must ensure stability, firmness, and good rigidity.

Mobile Traveling Mechanism

• The traveling mechanism of the mobile box includes rollers, mobile box, guide rails, chain transmission, and other parts. The suspension bolt is connected to the mobile box, and the chain drives the mobile box. The mobile box is equipped with rollers, which rotate on the guide rail.
• The walking guide rail is made of heavy-duty channel steel, and the walking      roller adopts a composite roller with bidirectional positioning. The bidirectional positioning between the roller and the guide rail ensures that the rotary refining device on the furnace side can move flexibly, smoothly, and without swinging; The internal bearing of the roller is a self-lubricating bearing, which is free from maintenance during equipment operation; This configuration of walking rails and rollers ensures the reliable operation of the furnace side rotating refining device in high-temperature and dusty casting sites.
• The electric motor, worm gear reducer, and chain sprocket form a chain transmission system to complete the movement of the mobile box; Select a worm gear reducer with good self-locking performance to ensure that the mobile box stops at any position within the walking range.
• The travel range of the mobile box is adjustable. Limit switches are installed at the front and rear limit positions of the mobile box to ensure reliable limit of the mobile box; The limit switch is installed inside the formed slide rail, which can conveniently adjust the travel limit position of the mobile box.

Trolley Travel System

• The equipment sits on a small car as a whole, which drives the equipment to rotate and walk, determining the refining position, and thus achieving refining and degassing in the furnace for two sets furnaces.

Rotor Rotary System

• The spindle rotation system includes rotating spindle box, spindle, rotating motor, pulley transmission system, and other parts.
• The spindle bearing is installed in the spindle box, which adopts a high-temperature resistant design to ensure that the spindle box can work continuously under high temperature radiation; The outer surface of the spindle box is coated with silicone high-temperature paint, the spindle is subjected to high-temperature quenching and tempering treatment, the bearings are high-temperature bearings, and the lubricating grease is high-temperature lubricating grease
•  The belt transmission system composed of an electric motor, a pulley, and a triangular belt ensures convenient adjustment and smooth transmission.
• The rotating spindle is finely processed through cylindrical grinding, and the maximum radial runout during the highest speed rotation is not greater than 0.1mm (measured at the rotor chuck)

Spindle Insulation Board

•  When the equipment is working, it protects the metal spindle and reduces heat intrusion;

Cooling System

•  External compressed air cooling； 
•  Circlulating heat dissipation design； 
•  Protection bearings； 
•  High temperature resistant graphite rod looseness；

Fluxing Feeding System

The rotary refining device on the furnace side is equipped with one set of powder adding device. The fluxing supply system adopts a rotating wheel for feeding, which can be used for conveying powder with a maximum diameter of 3mm. All powder supply components in contact with the powder are made of corrosion-resistant 316 stainless steel; An observation mirror is installed on the flux powder cylinder.
