How to Configure the Power Distribution Cabinet for an Aluminum Melting Furnace?

A suitable power distribution cabinet is the prerequisite for safely and efficiently running an aluminum melting furnace. Therefore, we need to configure a matchable power distribution cabinet for every furnace. Then, how to do that? Here are a couple of suggestions for this.

Determine the furnace's input power: The input power of the furnace is determined by the voltage and current required by the furnace. You can determine the furnace input power by determining the required voltage and the operating current.

Determine the furnace's output power: The output power of the furnace is determined by the amount of aluminum it can melt per hour. You can calculate the furnace's output power by multiplying the aluminum melting rate by the specific heat of aluminum (0.22kWh/kg °C) and the melting temperature of aluminum (660°C).

Determine the operating voltage: The operating voltage of the furnace is usually between 440V and 660V. It's important to select the appropriate operating voltage based on the output power of the furnace to ensure that the furnace operates safely and efficiently.

Determine the operating current: The operating current of the furnace is determined by the output power and operating voltage of the furnace. You can calculate the operating current by dividing the output power by the operating voltage.

Select the appropriate circuit breaker: The circuit breaker should be chosen based on the requirements for current and voltage. It's important to select a circuit breaker that is rated to handle the voltage and current required by the furnace.

Choose a suitable contactor: A contactor is required to switch the furnace on and off. The contactor should be chosen based on the voltage and current requirements.

Select the appropriate transformer: A transformer is required to step down the voltage of the electrical power supply. The transformer should be chosen based on the input voltage of the furnace.

Determine the cable size: The cable size should be chosen based on the maximum current rating of the furnace. It's important to choose a cable that can handle the current without overheating.

Connect the components: Mount all the selected components and wire them together according to the wiring diagram or schematic that comes with the furnace. Make sure that all connections are tight and secure.

Test the power distribution cabinet: After configuring the power distribution cabinet, it's important to test it to ensure that it's functioning correctly. Turn on the furnace and conduct a few test runs to check the power distribution cabinet's performance.

It's important to consult with a qualified engineer or electrician when configuring the power distribution cabinet for an aluminum melting furnace to ensure that it's safe and meets all relevant regulations.
