Metal melting furnaces can accurately control the temperature of materials, which helps improve the quality of finished products and ensure that the performance of metal materials meets expected standards; The automation operation of equipment reduces labor costs, simplifies operation, reduces the impact of human factors on the production process, and improves production efficiency and stability.

Maintenance and upkeep are relatively easy, with a long service life, reducing equipment downtime and repair costs, and saving operating costs for enterprises; Equipped with comprehensive safety devices and protective measures, the risk of accidents during use is low, ensuring the personal safety of operators; It can adapt to different production requirements and be customized according to customer needs. Whether it is precious metals, common metals such as copper, iron, aluminum, or special alloys such as alloy steel, it can be melted. It can also meet the specific needs of various industries such as jewelry processing.

Measurement steps for metal melting furnace:

1. Preparation work

-Equipment inspection: Check whether there are cracks or deformations in the furnace body, and whether the refractory materials of the furnace lining are intact; Confirm that the temperature sensors and controllers in the temperature control system are operating normally, and that the temperature display matches the actual heating power; Check whether the smoke exhaust duct is blocked or leaking, whether the ventilation equipment meets the standard for air volume, and ensure that the concentration of harmful gases in the work area is lower than the national standard; At the same time, check the integrity of the load-bearing components, lifting devices, and valves of auxiliary equipment such as cranes, ladles, molds, and other tools.

-Cleaning up residues in the furnace: Check if there are any residual materials left in the furnace from the previous batch. If there are, they should be cleaned thoroughly to avoid affecting the effectiveness and quality of this smelting process.

2. Loading operation

-Choose a suitable crucible and place it stably: Based on the type and quantity of metal to be melted, select a crucible of appropriate specifications and place it smoothly in the melting furnace to ensure that it will not move during subsequent heating processes.

-Adding metal materials: Slowly pour the pre treated (such as crushed, screened, etc.) and qualified metal raw materials to be melted into the crucible, taking care to avoid damage caused by metal impact on the furnace wall or other components.

3. Heating process monitoring

-Start the equipment to start heating: Turn on the power switch and other related control devices of the melting furnace, and start the heating function according to the preset program or parameters.

-Real time monitoring of temperature changes: Use temperature sensors to closely monitor the temperature rise during the heating process, ensuring that it can accurately reach the desired melting temperature. The melting points of different metals vary, for example, aluminum has a melting point of about 660 ° C, copper has a melting point of about 1085 ° C, and gold has a melting point of about 1064 ° C. The heating strategy needs to be adjusted according to the specific metal.

-Observing the state of the molten pool: During the heating process, pay attention to the formation and development of the molten pool, including fluctuations in the liquid level, the generation of bubbles, etc., in order to promptly detect abnormalities and take corresponding measures.

4. Component detection and adjustment (optional)

-Carbon content detection: Analyze the content of carbon elements in materials to prevent product quality from being affected by carbon pollution.

-Metal impurity detection: Detect the content of metal impurities such as iron, nickel, chromium, etc. to ensure that they meet production requirements.

-Non metallic impurity detection: detect the content of non-metallic impurities such as sulfur and phosphorus, and perform corresponding impurity removal treatment if necessary.

5. Conclusion and Sampling Analysis

-Stop heating and cooling: When the metal melts and reaches the expected level of refinement, turn off the heating device and let the molten metal cool naturally or use appropriate forced cooling methods to solidify it.

-Sampling and testing: Select representative samples from the solidified metal ingot for chemical composition analysis, physical property testing, etc., to verify whether the melting effect meets the process standards.
