Copper Brass Bronze Melting Furnace

A copper, brass, and bronze melting furnace is a device that can heat and melt metals with high melting points, such as copper (1085°C), brass (900-940°C), and bronze (850-1000°C).?There are different types of furnaces that can be used for this purpose, such as gas, electric, induction, or microwave.?Some factors to consider when choosing a furnace are the capacity, efficiency, safety, and cost of the equipment.Today we talk about the induction melting furnace used in the copper brass broneze melting casting applications.

Induction melting furnaces use electromagnetic induction to heat and melt metals without direct contact.?They are more energy-efficient, environmentally friendly, and precise than other types of furnaces.

How to melt the copper brass bronze with induction melting furnace?

copper brass bronze melting furnace working process

To melt copper, brass, and bronze with an induction melting furnace, you need to follow these general steps:

• Prepare the metal and the crucible. You can use scrap metal or ingots of copper, brass, or bronze. Make sure they are clean and dry. You also need a crucible that is compatible with induction heating and can withstand high temperatures. You can choose from graphite, ceramic, or clay-graphite crucibles.
• Place the metal and the crucible inside the furnace. Make sure the crucible is centered and secured in the furnace. The metal should fill about 80% of the crucible’s volume.
• Turn on the furnace and set the desired temperature. The furnace will use electromagnetic induction to heat up the metal without direct contact. The temperature will depend on the type and amount of metal you are melting. For example, copper melts at 1085°C, brass melts at 900-940°C, and bronze melts at 850-1000°C.
• Monitor the melting process and stir the metal occasionally. You can use a pyrometer or a thermocouple to measure the temperature of the metal. You can also use a graphite rod or a ceramic spoon to stir the metal and remove any impurities or slag that may form on the surface.
• Pour the molten metal into a mold or a casting machine. When the metal is fully melted and reaches the desired temperature, you can turn off the furnace and carefully lift the crucible with tongs or a lifting mechanism. You can then pour the molten metal into a preheated mold or a casting machine to produce your desired shape.

How long does it take to melt copper, brass or bronze with an induction furnace?

The time it takes to melt copper, brass, or bronze with an induction furnace depends on several factors, such as the power of the furnace, the size and shape of the crucible, the amount and purity of the metal, and the ambient temperature. However, as a general estimate, you can use the following formula to calculate the melting time in minutes:

where:

·???????? t is the melting time in minutes

·???????? m is the mass of the metal in kilograms

·???????? c is the specific heat capacity of the metal in J/kg°C

·???????? T_m is the melting point of the metal in °C

·???????? T_a is the ambient temperature in °C

·???????? P is the power of the furnace in watts

·???????? e is the efficiency of the furnace (usually between 0.5 and 0.8)

For example, if you want to melt 5 kg of copper with a 10 kW induction furnace at an ambient temperature of 25°C, and assuming an efficiency of 0.7, you can plug in the values into the formula:

This means it will take about 27.6 minutes to melt the copper. However, this is only an approximate value, and the actual melting time may vary depending on the conditions of your furnace and metal.

How to choose the suitable and commercial induction melting furnace?

Choosing a suitable and commercial induction melting furnace requires careful consideration of several factors, such as:

• Your production goal: You need to determine the amount and type of metal you need to melt per hour or shift, and the desired process time. Furnaces come in various capacities and frequencies, depending on the volume and melting point of the metal.
• Your energy efficiency: You need to choose a furnace with sufficient power and features to melt your metal efficiently and reduce energy consumption. Induction furnaces are generally more energy-efficient and environmentally friendly than other types of furnaces.
• Your desired features: You need to look for furnaces that offer features that cater to your specific needs, such as tilting mechanism, automatic temperature control, vacuum capability, safety features, etc.
• Your manufacturer and service: You need to choose a reputable and experienced manufacturer that offers a good warranty and service support. You can also compare the prices and quality of different products and brands.
