Aluminum melting furnace is a very widely used equipment in industrial production, including rectangular aluminum melting furnace, circular aluminum melting furnace, double-chamber furnace, etc., and its use involves many aspects. In order to ensure a safe and stable production process, there are a few key things to pay special attention to when using an aluminium melting furnace. The following is a detailed description of what you need to pay attention to when using an aluminum melting furnace to help you better operate and maintain your equipment and improve production efficiency.
First, the heating process.
After starting the furnace, it is necessary to adjust the heating parameters to a stable state, which is the prerequisite for normal heating production.
Second, boot check.
Before starting the machine, it is necessary to conduct a comprehensive inspection of the pushing, discharging device, circulating water, air pressure, etc., to ensure that it is normal. At the same time, it is necessary to pay attention to the position of the limit switch and the manual automatic switch to ensure that it is within the required range. The material on the workbench needs to meet the forging requirements, and always pay attention to the cooling water to ensure that the outlet water temperature does not exceed 60.
Third, the loading process.
When loading, the aluminium needs to be placed correctly. Large pieces of aluminium need to be properly processed before loading the furnace with the irregular side facing up to avoid jamming the furnace lining.
Fourth, the first firing.
When firing material for the first time in a cold furnace state, the rated power should not be used immediately. It is recommended to use 60%-75% of the normal power for low-temperature heating to avoid cracks in the refractory lining of the furnace lining. When the temperature of the lining reaches about 90 evenly, the power can be increased to the normal process power and the formal forging operation can begin.
5. Material management.
Blanks of both parts should not be placed in front of the furnace and on the bench at the same time. Before leaving work, the furnace foreman needs to load the heated remaining blank into the bin and indicate the specification and status. The red material in the induction furnace should be forged. When the size and shape of the blank changes (such as shortening the length or adding a new size), the material cannot be discharged and pushed at will, and relevant calculations need to be carried out according to the design requirements of the inductor to ensure the heating quality of the blank and avoid heating defects.
6. Furnace structure design.
Rational design of furnace structure is the key to improving the efficient use of energy. The main factors include refractory materials, thermal insulation, furnace structure, control system, and burner system, among others. Refractory insulation materials have excellent heat resistance, which can reduce energy consumption and improve energy saving effect.
Therefore, in practice, strict compliance with the above regulations is the key to ensure the safe operation of equipment and the smooth progress of production. Be sure to operate the aluminium melting furnace in accordance with the above requirements to ensure safe and stable production.
