Motor Chain Tilting Small Induction Furnace
FIXED-POINT POURING FOR SMALL INDUSTRIAL BATCHES
Motor Chain Tilting Small Induction Furnace
The COOLDO motor chain tilting induction furnace uses an electric gear motor and chain drive to rotate the crucible furnace around a controlled pouring axis. It is designed for repeatable small-batch melting and accurate mold filling where a fixed pouring point is more important than a heavy-duty hydraulic structure.

What Is a Motor Chain Tilting Induction Furnace?
A motor chain tilting induction furnace combines an IGBT medium-frequency power supply, water-cooled induction coil, crucible furnace body, geared motor and chain transmission. After the metal reaches the qualified pouring temperature, the motor drives the chain and rotates the furnace body so the melt flows into the prepared mold.
The main product advantage is the controlled pouring path. When the pivot and mold position are properly designed, the pouring point stays more stable as the furnace tilts. This supports repeated ingot or component casting in small and medium industrial workshops.
- Drive method
- Electric gear motor and chain transmission.
- Heating method
- IGBT medium-frequency induction.
- Primary metal basis
- Copper and compatible non-ferrous alloys.
- Main application
- Controlled small-batch mold pouring.
Chain-Drive Tilting and Fixed Pouring Point
The motor, reducer, chain, pivot and mold position must be engineered as one pouring system.
Why Use Motor Chain Tilting?
The geared motor applies controlled motion through the chain to the tilting furnace body. Compared with lifting and pouring a crucible manually, the operator can control the rotation from a safer working position and maintain a more repeatable pouring path.
- Fixed-axis movement supports consistent pouring position
- Remote tilt switch keeps the operator away from the immediate stream
- Compact mechanical layout suits small production cells
- Chain tension, guards, limit switches and reducer require scheduled inspection
Power, Temperature and Tilt Control
The original page describes 10-100 percent power adjustment, real-time power display, thermocouple or infrared temperature measurement and automatic tilting control. The correct temperature method depends on the metal, temperature range, emissivity, atmosphere and required accuracy.
Remote operation improves separation, but it does not eliminate molten-metal risk. Charge, crucible, mold and tools must be dry, and the pouring zone must be guarded and kept clear.
IGBT Power Supply
Provides adjustable medium-frequency energy for responsive small-batch melting.
Induction Coil
Water-cooled copper tubing requires stable water quality, pressure, flow and temperature.
Gear Motor
A geared drive supplies controlled torque for furnace rotation and pouring.
Chain Transmission
Chain, sprocket, guards and tensioning system transfer motor motion to the furnace body.
Crucible System
Graphite, silicon-carbide graphite or engineered refractory is selected for the metal.
Remote Controls
Power and tilt controls coordinate heating, positioning and mold filling.
Published CDO-CT Chain Tilting Furnace Specifications
The table below preserves the model-specific values published on the original page while presenting copper as the principal industrial capacity reference.
| Parameter | CDO-CT25 | CDO-CT35 | CDO-CT45 | CDO-CT70 |
|---|---|---|---|---|
| Rated power | 25 kW | 35 kW | 45 kW | 70 kW |
| Input supply | Three-phase 380 V, 50/60 Hz | |||
| Published maximum temperature | 1500°C | 1500°C | 1500°C | 1500°C |
| Published melting-time reference | 8-10 min | 15-18 min | 20-25 min | 30-40 min |
| Published crucible material | Pure graphite | Pure graphite | Silicon-carbide graphite | Silicon-carbide graphite |
| Published copper capacity | 20 kg | 30 kg | 30 kg | 50-100 kg |
Important: melting time depends on actual batch weight, charge form, starting temperature, target superheat, crucible, voltage and operating practice. The original page lists approximate overall dimensions without assigning them to individual models; request a model-specific layout drawing before installation.
Ferrous-metal projects: do not select a steel or stainless-steel furnace only from the 1500°C standard table. Send the exact alloy, liquidus range, pouring temperature and batch weight so the power, coil, lining or crucible, cooling system and qualified operating temperature can be engineered separately.
Motor Chain Tilting vs Hydraulic Tilting Furnace
Both designs automate pouring, but they serve different batch weights and production priorities.
Motor Chain Tilting
- Gear motor and chain transmission
- Useful for repeated small-batch mold pouring
- Compact mechanical arrangement
- Published copper reference up to 100 kg
- Requires chain, sprocket and guard inspection
Hydraulic Tilting
- Hydraulic cylinder and pump system
- Suitable when load, torque or pouring control favors hydraulics
- Published separate CDO-HT product range
- Requires hydraulic hose, seal and oil maintenance
- See the hydraulic tilting metal melting furnace for model comparison
Final selection depends on metal, real batch weight, center of gravity, pouring height, mold arrangement, required stream control, production frequency and maintenance capability.
Typical Melting and Chain-Tilting Pouring Process
The operating procedure must be qualified for the exact metal, crucible and mold.
Inspect
Check crucible, chain, guards, reducer, coil, water, grounding and interlocks.
Prepare Charge
Use clean, dry, identified metal free from sealed or wet contamination.
Load
Charge without striking the crucible and remain below the approved fill level.
Melt
Apply power progressively and monitor bath condition and cooling water.
Prepare Mold
Position, dry and secure the mold at the approved fixed pouring point.
Tilt and Pour
Use remote motor control to rotate the furnace and fill the mold smoothly.

Motor Chain Tilting Induction Furnace FAQs
Direct answers for chain drive, fixed-point pouring, copper capacity, ferrous projects and installation.
What is a motor chain tilting induction furnace?
It is a crucible induction furnace whose gear motor drives a chain and rotates the furnace body around a controlled axis for mold pouring.
What is the main advantage of chain tilting?
The pivot and chain-drive arrangement can provide a stable pouring path and fixed pouring point, helping the operator align repeated small batches with the mold.
What standard power models are published?
The current published table lists CDO-CT25, CDO-CT35, CDO-CT45 and CDO-CT70 with 25, 35, 45 and 70 kW rated power.
What is the copper melting capacity?
The published copper references are 20 kg, 30 kg, 30 kg and 50-100 kg for the four standard models. Final usable capacity depends on crucible dimensions, safe fill level and process conditions.
How long does one batch take to melt?
The published table gives 8-10, 15-18, 20-25 and 30-40 minutes by model. Because the models carry different batch sizes, higher power does not automatically mean the shortest listed cycle. Actual performance must be evaluated at the quoted load.
Can this furnace melt brass and bronze?
Yes, when the crucible, temperature program, fume extraction and alloy practice are suitable. Zinc-containing brass requires controlled temperature and effective ventilation.
Can this furnace melt aluminum?
A chain-tilting furnace can be configured for aluminum, but the capacity must be calculated from aluminum density and the selected crucible volume. Do not use the published copper kilogram value as the aluminum capacity.
Can the standard 1500 degree C model melt steel?
Do not assume so. Steel grades have different liquidus and pouring temperatures, and the furnace needs adequate temperature margin, lining or crucible, power and cooling. COOLDO should verify the exact alloy and batch before quoting a ferrous configuration.
What is the difference between chain and hydraulic tilting?
Chain tilting uses a gear motor, chain and sprocket and is compact for repeated small-batch pouring. Hydraulic tilting uses a cylinder and hydraulic power unit and may be preferred where load, torque or motion control requires it.
Is remote chain tilting safe?
Remote control helps increase distance from the pouring stream, but it does not remove molten-metal hazards. Guards, limit switches, dry charge and molds, PPE, training and a clear pouring zone remain necessary.
Why must all charge and tools be dry?
Water entering molten metal can rapidly generate steam and cause a violent explosion. Scrap, molds, tools and additions must be inspected, prepared and dried under the site's qualified procedure.
What maintenance does the chain drive require?
Inspect chain condition and tension, sprockets, guards, reducer, fasteners, pivot bearings, limit switches and electrical controls at the intervals defined in the approved manual.
What utilities are required?
The installation normally needs suitable three-phase power, transformer capacity, closed-loop cooling water, grounding, fume extraction, floor space and a protected pouring area. Final requirements are model-specific.
What information is needed for a quotation?
Send the metal grade, kilograms per heat, charge form, required output, melting and pouring temperature, mold layout, available voltage, transformer capacity, cooling-water conditions and installation country.
Need a Chain Tilting Furnace for Fixed-Point Pouring?
Send the alloy, batch weight, daily output, mold arrangement and plant utilities for a matched furnace proposal.
