The electric foundry furnace uses an intermediate frequency induction furnace on the equipment used in the original foundry industry. The working principle is: the metal is smelted into a liquid that meets certain requirements and poured into the mold. After cooling, solidification, and cleaning, a predetermined shape is obtained. , size and performance of the casting process.

The casting blank is almost formed, and the purpose of free machining or a small amount of processing reduces the cost and reduces the time to a certain extent. Casting is one of the basic processes of the modern manufacturing industry. Casting is more efficient and energy-efficient, cost-effective and environmentally friendly using a medium-frequency induction furnace.Vacuum Brazing Technology of Static Guide Vane RingCasting is one of the most important and most basic processes in the machinery manufacturing industry. The most basic method is sand casting. The main processes include modeling, alloy smelting, pouring, and casting sand cleaning. The main occupational disease hazard factor is dust, which can exist in In many aspects of casting, including crushing, sand screening, sand mixing, molding, falling sand, sand cleaning, sand blasting, etc., long-term inhalation of foundry dust can cause pneumoconiosis in casters. Melting, pouring and hot castings are all heat sources. Melting workers and casting workers will be affected by high temperature and strong heat radiation. The smelting and casting process can also generate carbon monoxide, sulfur dioxide and metal fumes.

In addition, the mechanical equipment used in the process of shaking, compacting, falling sand and cleaning can also generate noise and vibration. Therefore, casting should first try to use molding sand with low free silica content, and reduce manual molding and sand cleaning operations, especially sand cleaning operations are the positions with the highest dust concentration in casting, and should be protected.Vacuum Brazing Technology of Static Guide Vane Ring
For example, install a high-power ventilation and dust removal system, implement spray wet operation to reduce the dust concentration in the workplace, wear dust masks that meet relevant national standards, and do a good job of occupational health inspections for workers in accordance with relevant regulations
