AZ31B Extruded Magnesium Anodes Rod Replacement Casting

Continuous Drawing Production Process Extruded Magnesium Anode Meets High Cathode Current Requirements

Introduction:

The high current output/weight ratio of the rod anode allows for its wide application in circumstance that demands a small anode diameter and high cathodic current.

we provide two types of extruded magnesium alloy anode: Mg-Mn alloy with high potential and AZ31 alloy with standard potential.

Features:

The extruded magnesium alloy anode rod adopts a continuous drawing production process. The surface of the product is smooth, without pores and slag inclusions, the potential is greater than 1.48V, the efficiency is greater than 55%, and the bar yield is over 98%.

Production Process:

1. Casting equipment

The use of a high-power resistance furnace can realize automatic temperature control, and the efficiency of stretching equipment is greatly improved.

2. Melting and pouring process

The charging materials should be placed as densely as possible to reduce the gap between the charging materials. Then gradually increase the temperature. When 1% of the total charge is melted, the furnace temperature is adjusted to 730 °C for metamorphism treatment, and samples are taken for fracture inspection.

The key to adopting the low-pressure oxygen-free casting process is the coordination and synchronization of the casting speed, the stretching speed and the cooling water volume. Otherwise, there will be under-pouring and interruption of the stretch rod.

3. Inspection and sawing

After the drawn bar products pass the sawing gate and the appearance inspection, the necessary heat treatment is carried out in the heat treatment furnace, and then the second sawing is performed according to the length required by the user.
