The car bottom resistance furnace is used in the metallurgy industry for various applications. The following are some of the most common car bottom resistance furnaces with distinctive features.
Industrial Electric Car Bottom Resistance Furnaces
This kind of industrial electric car bottom resistance furnace is popular among many industries for metal heating and melting. Generally speaking, its design features strong resistance coils in the furnace bottom. These coils provide uniform heat distribution for materials placed inside the furnace. In addition, the capacity of medium-sized furnaces usually meets average production demands. Moreover, electric power is the most common source of energy. So, it is applicable to many situations where electricity is available. What's more, the automatic temperature control system allows operators to precisely adjust and maintain the required heating temperature. This helps to improve the consistency and quality of the final product. Therefore, this type of car bottom resistance furnace can be used to melt and heat metals.
Small Bottom Resistance Electric Car Furnaces
Similar to industrial electric ones, small bottom resistance electric car furnaces are ideal choices for small workshops and labs. Their compactness makes them space-saving. Meanwhile, they are usually easy to operate and quick to set up. Therefore, small businesses can choose to use them without too much initial investment. Additionally, the energy consumption of small bottom resistance electric car furnaces are lower. This is helpful for companies to cut costs and improve economic efficiency. Although the capacity is smaller than that of large industrial ones, they can still afford small-scale production needs.
Oimura Model Bottom Car Resistance Furnaces
The Oimura Model bottom car resistance furnace is a specific design based on the original Oimura models. Its structure and functioning elements might be slightly different from standard bottom car resistance electric furnaces. Generally, Oimura models use an electric resistance method to heat up metals. They achieve uniform and exact temperature control through bottom resistance heating. This provides good quality for metal processing needs. The Oimura model bottom car resistance furnaces are usually used in particular industrial fields and are preferable choices for some specific production lines.
The specifications of car bottom furnaces can vary based on the model and intended industrial application. Generally, these furnaces have a heating capacity of around 1,000-3,000 kg/h, which is suitable for different melting points of metals like aluminum, copper, and alloys. The power supply can be electric or gas, with an electric power ranging from 100 to 500 kW, while gas involves a flow of 50-150 m3/h. The temperature controlling system is highly sensitive, with a control deviation of about ±1%, allowing the furnace to function optimally and meet the requirements for processing various materials at precise temperatures. The operating environment of the furnace can be atmospheric or a vacuum of 10-3 mbar or less. The furnace can also withstand temperatures of up to 1,000-1,600 °C for heating elements like refractory lining, which depends on the materials used.
Although car bottom resistance furnaces are heavy-duty and robust pieces of industrial equipment, regular maintenance and care can help them work longer. This includes cleaning the furnace regularly to remove soot and debris, recalibrating the temperature control system to ensure accuracy, and routinely inspecting the refractory lining and replacing it whenever necessary. Users need to establish a preventive maintenance schedule, which includes inspections and standard servicing, and ensure all moving parts are lubricated. During operation, operators must be aware of the signs of potential problems, such as unusual noises, drops in temperature, or overheating, and they should address them immediately. Regularly, the electrical and mechanical components of the furnace should be checked, and the furnace's cooling system must be inspected to avoid overheating.
