Ladle Heaters
Industrial Ladle Heating Systems for Foundry Applications
ATD Engineering & Machine manufactures industrial ladle heaters and ladle heating systems custom-built to your ladle or pouring box design. Our Engineering team starts with your existing ladle or pouring box design and develops a new lid with various insulation and refractory linings to accompany the combustion system. Our modulated, unmodulated, and simple ladle heater models, also used as ladle preheaters, help prepare refractory-lined vessels for service by reducing thermal shock, minimizing refractory cracking, and limiting molten metal temperature loss. Designed for foundry applications, ATD ladle heating systems support refractory bake-out, ladle preheating, and temperature maintenance across a range of production environments.

Wide range of BTU’s
Ramp / Soak recipe control for refractory bake out and longer refractory LIFE!!
Modulated Ladle Heaters
ATD’s Modulated ladle heaters have fully automatic temperature controls and turn down. Once the heater reaches the temperature set point, it will throttle down and hold the temp. This is the most efficient ladle heater ATD produces, and we have worked with gas utility companies to determine cost savings for our customers. Some of these studies have shown that when using a Modulated ladle heater, you can reduce your gas and compressed air consumption by over HALF in comparison to a simple drop pipe.
Many customers use the ATD modulated ladle heater for baking out new refractory, as it also has full ramp/soak features that can be uniquely programmed for each ladle or pouring box

Unmodulated Ladle Heaters
Our unmodulated ladle heaters all have the same flame safety as our modulated versions, but the temperature is not controllable. We have implemented timers into these systems so that customers can avoid overheating a ladle or pour box.

Simple Ladle heaters
This type of ladle heater has minimal controls and safety features. The simple ladle heaters are compact and can be adapted to fit anywhere in your foundry.

Which Ladle Heating System Is Right for Your Foundry
Continuous Production
Modulated ladle heaters provide automatic temperature control and variable burner output for continuous production and controlled refractory bake-out.
Refractory Bake-Out:
Ramp/soak control provides programmable heating profiles for gradual temperature increases during new or relined refractory bake-out.
Simple, Timer-Based Operation
Unmodulated ladle heaters provide flame safety and timer-based operation for applications where automatic temperature modulation is not required.
Limited Space
Simple ladle heaters offer a compact, minimal-control solution for installations with space or layout constraints.
Energy Efficiency
Modulated systems adjust burner output as the set temperature is reached, helping reduce gas and compressed-air consumption compared with simple drop-pipe systems.
Applications of Ladle Heating Systems
ATD ladle heaters and ladle heating equipment are used across a range of foundry applications, including.
Ladle Preheating:
Initial heating of ladle refractory lining before molten metal contact.
Pouring Boxes:
Heated refractory vessels or equipment used for molten metal transfer and pouring applications.
Refractory Bake-Out:
Controlled heating of new or relined refractory to remove moisture and condition the lining.
Ladle Temperature Maintenance:
Controlled heating between heats or during extended production cycles.
Transfer Ladles:
Molten metal transfer between melting, holding, treatment, and pouring operations.
Ferrous Foundries:
Iron and steel casting operations requiring ladle preheating or refractory conditioning.
Pouring Ladles:
Molten metal delivery from ladles into molds during casting operations.
Non-Ferrous Foundries:
Aluminum, bronze, and non-ferrous casting requiring ladle or pouring equipment heating.

FREQUENTLY ASKED QUESTIONS
-
Modulated ladle heaters provide automatic temperature control and reduce burner output as the set point is reached. ATD customer studies have shown gas and compressed-air consumption reductions of more than half compared with a simple drop pipe. Unmodulated heaters use the same flame safety systems but rely on timers rather than automatic temperature control.
