How to Avoid Collision and Fall Damage of Graphite Crucible in the Process of Using?

In order to avoid the graphite crucible from collision and falling during the use, the following steps and principles can be followed:

Placement and Movement

Avoid dropping the graphite crucible from a high place or hitting it on other objects. When moving and placing, use appropriate tools and methods, such as using crucible clamps or soft cushions, to minimize the impact force on the crucible.

Do not place graphite crucibles directly on the floor, but place them on stacked boards or wooden racks to minimize direct contact and friction with the floor.

Avoid rolling horizontally when handling the graphite crucible, especially when it is pushed vertically to the floor, the floor needs to be padded with something soft such as thick cardboard or rags to prevent rubbing the bottom.

Precautions for Use

Before using, the graphite crucible should be checked whether there are obvious cracks or defects, if so, avoid using it so as not to cause safety accidents due to rupture.

When putting in raw materials, avoid using mechanical force or forcible holding to prevent impact and damage to the crucible.

During use, avoid pointing the flame directly at the bottom of the crucible, as prolonged high temperatures may cause damage to the bottom of the crucible.

Remove the remaining metals such as aluminum and copper as soon as possible after use to avoid residual liquid in the crucible, which can reduce corrosion and damage to the crucible.

Use of Acidifiers and Other Chemicals

When using acidifying substances (such as slag removers, etc.), care should be taken to use them in moderation; overuse may erode the crucible and lead to rupture.

Maintenance and Storage

The graphite crucible should be cleaned in time after use to avoid corrosion of the crucible by residue. When cleaning, you can use soft brush or cotton cloth to wipe, avoid using sharp tools to scratch the crucible surface.

Graphite crucible should be stored in dry, ventilated and lightproof place, avoiding direct sunlight and humid environment. When storing, it is better to place the graphite crucible on a wooden frame or soft cushion to reduce the external impact.

Regularly check and maintain the graphite crucible, if cracks, breakage and other problems are found, it should be replaced in time.
