Question

What is the use of vertical lifting tongue in metal casting?

• A. to take out the crucible
• B. to pour the melted metal
• C. to separate the metal
• D. to clean the metal

Hint:

In a foundry, specialized tools are named for their specific function. "Lifting tongs" are for lifting the crucible, while a "pouring shank" is often used to hold the crucible for the actual pouring.

Answer 1

The Correct Option is A

Step 1: Identify the equipment. A crucible is a container used for melting and holding metal at high temperatures in a furnace. "Vertical lifting tongs" (often called crucible tongs) are specialized tools designed to handle this hot and heavy container.
Step 2: Determine the function of the tool. The design of vertical lifting tongs allows a foundry worker to securely grip the crucible and lift it straight up out of the furnace. This is essential for safely transporting the molten metal to the mold for pouring. Therefore, their primary use is to take out the crucible from the furnace.
