1、Device Description of 0.5t induction melting furnace
Equipment: Medium frequency coreless induction melting furnace for casting workshop cast iron and cast steel smelting work
This 0.5t induction melting furnace is a power-saving product with the characteristics of fast heating speed, low energy consumption and stable and reliable operation. The service life of complete sets of equipment is designed and manufactured according to not less than 20 years, and the equipment control technology is in the leading position in the same industry within five years.
Two sets of 600kw series intermediate frequency power supply, two steel shell hydraulic furnace bodies, two sets of PLC auxiliary melting management system and so on. The PLC-assisted smelting management system not only displays the real-time data and information of the power supply operation, but also displays the operating status and information of the entire system, and has automatic oven, cold furnace start, fault diagnosis, fault information display and storage, and operation information display. , system status display and other functions.
When designing the equipment, the user's on-site working status is considered to be continuous, and the furnace is frequently discharged. The equipment selection of this scheme ensures the user's output index and meets the user's overall requirements for the equipment: the equipment is durable and performance. Stable, safe and reliable.
2、Project Description
Party A is responsible for the civil works and the construction of the high-voltage side of the transformer to the transformer connection. Party B is responsible for providing the drawings and materials required for the construction.
Party B is responsible for electrical construction and electrical materials (including materials required for waterways) below the intermediate frequency power supply.
Acceptance is divided into three times
Initial acceptance: In the factory of Party B, it mainly checks and accepts all the parameters and quantity models of the equipment. After the two parties confirm the correctness, they can sign the goods and ship them.
Pre-acceptance: In Party A's factory, after Party B's installation, Party A's acceptance of the equipment before commissioning is mainly the equipment layout and the acceptance of on-site installation materials and processes. After acceptance, both parties agree on the whole machine commissioning time.
Final acceptance: The equipment is operated for 24 hours or 24 times at full power according to the designed index parameters. The equipment meets the equipment standards and is qualified.
The final acceptance time is no more than 10 working days.
Within 30 days after the completion of the installation and commissioning, Party A cannot arrange for the final acceptance of equipment commissioning as the default final acceptance.
