In the metal casting industry, melting copper is a demanding process. Copper's melting point of 1084°C imposes demanding standards on the performance of smelting equipment, especially in terms of high temperature resistance and heat transfer efficiency. With its excellent physical and chemical properties, silicon carbide graphite crucible has become the ideal crucibles for melting copper, bringing more efficient and economical melting solutions for enterprises.
Why choose silicon carbide graphite crucible?
Sic graphite crucible not only meets the needs of high temperature melting, but also outperforms traditional crucible in terms of service life, energy efficiency and maintenance cost. The following is a detailed breakdown of its core advantages:
1. High thermal conductivity
The thermal conductivity of silicon carbide graphite crucible is significantly higher than that of ordinary materials, which means:
Fast heating: can quickly transfer heat to the inside of the crucible, improve melting efficiency.Significant energy savings: reduced heating time, lower gas or electricity consumption, thus reducing energy bills. 2. High temperature and thermal shock resistance Silicon carbide graphite material can withstand high temperatures above 1300°C, while having excellent thermal shock resistance:
Heating stability: In the process of repeated high temperature melting and cooling, not easy to crack or deformation.Longer life: Withstand frequent temperature fluctuations, especially suitable for high-intensity production environments. 3. Excellent corrosion resistance During copper smelting, acidic or alkaline slag will be produced, which may cause corrosion to the crucible. The characteristics of silicon carbide graphite crucible are:
Chemical erosion resistance: It can effectively resist slag infringement and maintain structural integrity. Longer service life: Reduce the frequency of replacement due to corrosion and save costs for enterprises. 4. Extend service life Compared with the traditional clay-graphite crucible, the service life of silicon carbide graphite crucible can be extended by 20%-30%. This not only reduces the frequency of replacement, but also reduces maintenance costs.
Choosing high-quality crucibles for melting copper: How to evaluate and select?
1. Determine the size and specifications
Select the appropriate crucible size according to the production requirements to ensure that it can meet the requirements of equipment capacity and copper melting amount.
2. Focus on technology
The crucible using isostatic pressing process has higher density and stronger crack resistance, which is a symbol of high quality crucible.
3. Material quality certification
Ensure that the crucible uses high-purity silicon carbide and graphite materials to provide a more stable melting effect.
4. After-sales service guarantee
Choose a supplier with a comprehensive after-sales service, such as a company that provides technical support, customized solutions and replacement recommendations.
How to melting copper in a crucible: A practical guide
In order to give full play to the performance of silicon carbide graphite crucible, the correct use method and maintenance are crucial. Here's some professional advice:
1. Preheat properly First use: Preheat the crucible at a low temperature of 200°C-300°C for 2 hours, and then gradually rise to the working temperature. Daily use: Avoid sudden cooling and sudden heating to reduce the impact of thermal shock on the crucible. 2. Control the melting temperature Recommended temperature range: 1100°C to 1300°C to ensure that the copper is fully melted, while avoiding premature aging of the crucible material due to excessive temperature. 3. Cleaning and storage Timely cleaning of slag: After each use, remove the surface and internal residue of the crucible to keep its performance stable. Storage conditions: The crucible should be stored in a dry, ventilated environment to avoid moisture or chemical damage.
