Ingot Casting car

Overview

We provide an Ingot Casting Car developed from 3 concepts in response to on-site demands for bottom pouring ingot manufacturing (casting) work.

・3 Development Concepts

3 Development Concepts
1.Safety

Conventionally, bottom pouring ingot manufacturing (casting) is done while suspending the ladle from an overhead crane. This conventional method has the following problems, which we have solved with the ingot casting car.

Before casting begins, an argon curtain must be attached to the outlet for the hot metal (sliding nozzle) to prevent oxidation from contact with the outside air. This is a very dangerous operation that involves going underneath the hanging ladle and requires the work of two crane operators.

With the ingot casting car, the ladle is not suspended by a crane, but is instead placed on a sturdy frame, significantly increasing the safety of the work.

2.Labor Reduction and Operability

The conventional method of working from a ladle suspended by crane led to the following problems related to work efficiency. The ingot casting car resolves these issues.

 

  1. Because a crane is used, both workers and crane operators are necessary.
    Also, workers are needed to route the hydraulic hose for the sliding nozzle and the hose for the argon curtain, which prevents oxidation. Thus, casting work requires at least three workers.

    By using the ingot casting car, workers can use a remote control to manipulate the car on their own, and furthermore, the hoses are all stored inside the car so that the work may be done by only one worker, providing for significant labor savings.

  2. Before casting begins, it is necessary to position the sliding nozzle over the pouring pipe.
    This work involves workers and crane operators signaling to each other while setting the position and it requires skilled technique to perform.

    The ingot casting car can perform the same functions as a crane (traverse, travel, lift), while it is also capable of being operated by a casting worker using remote control, making the positioning much easier.

Crane Type: 3 Casting Workers

Ingot Casting Car: 1 Casting Worker

3.Equipment Efficiency + Simplification = More Compact Layout

Conventional casting work using an overhead crane with the following factory layout requires a car between buildings to transport the ladle from the steelmaking yard to the ingot casting yard.

By properly arranging the ingot casting car, the car between buildings becomes unnecessary, as does the need to reposition the ladle.

Furthermore, the overhead crane becomes free for other work such as ingot extraction or mold preparation, allowing for more efficient use of the crane.
