铜缸铸造是一项传统技艺，其制作过程需要严格控制每个环节的质量和细节，那我们应该如何在铜缸铸造过程中避免划伤和沾灰呢！

Copper cylinder casting is a traditional craft, and its production process requires strict control of the quality and details of each link. So how should we avoid scratches and dust during the casting process!

1. 铸造时必须严格控制温度，过高的温度会导致铜缸变形或产生气孔；温度过低则会造成缩松现象。

1. During casting, temperature must be strictly controlled. Excessive temperature can cause deformation of the copper cylinder or the formation of pores; If the temperature is too low, it will cause shrinkage and looseness.

2. 浇注时必须保证铜液均匀注入模型中，防止出现未充满的现象。

2. During pouring, it is necessary to ensure that the copper liquid is evenly injected into the model to prevent underfilling.

3. 修整和抛光时要保持铜缸表面的平整度和光泽度。

3. When repairing and polishing, it is necessary to maintain the flatness and glossiness of the surface of the copper cylinder.

4. 包装前必须确保铜缸表面干净整洁，避免沾染灰尘或划伤表面。

4. Before packaging, it is necessary to ensure that the surface of the copper cylinder is clean and tidy, avoiding dust or scratches on the surface.

5. 在整个制作过程中，要注意安全，防止高温和尖锐的工具伤害自己或他人。

During the entire production process, attention should be paid to safety to prevent high temperatures and sharp tools from harming oneself or others.
