A case study in a gravity die-casting industry

One of a cast house reached out to us for an issue that they have been facing for quite some times. A temperature drop in launder of a gravity die-casting department, on the H-line. The temperature is low in the launder between the first holding furnace and a second holding furnace where the aluminum is poured.

Problem encountered by the die-casting house:

High power consumption

Low productivity

Low aluminum quality

Initial launder’s specifications:

A roof heating system

32 kW radiation

Closed lids

aluminium furnace solution

Challenges for the aluminum handling in the launder:

The aluminum temperature in launder: 611°C

The roof heating system was not able to maintain nor improve the temperature they wanted to have in the launder (from 735°C up to 780°C).

The aluminum had to spend more time in the second furnace in order to reach the right temperature in order to cast quality parts.
