Heat Treatment & Furnace Industry
Application Based Centrifugal Casting Solutions
Application 1: Furnace Rolls
Application Overview
Furnace rolls are used in continuous heat treatment lines and steel processing plants. They support material movement at elevated temperatures and must withstand mechanical load combined with thermal stress.
Why Centrifugal Casting for Furnace Rolls?
Centrifugal casting provides superior outer density, structural rigidity, and uniform material properties along the roll length. This enhances load-bearing capacity and thermal fatigue resistance.
Casting Requirements
| Parameter | Requirement |
| Roll Diameter | 200 mm – 1500 mm |
| Length | Up to 5 meters |
| Material Grades | Heat resistant Cr-Ni alloys |
| Load Capacity | High mechanical load support |
| Straightness | Controlled post-solidification machining |

Application 2: Radiant Tubes
Application Overview
Radiant tubes are critical heating components used in heat treatment furnaces, annealing lines, and thermal processing plants. These tubes operate continuously at high temperatures and must maintain structural integrity under thermal cycling conditions.
Why Centrifugal Casting for Radiant Tubes?
Centrifugal casting ensures directional solidification, dense outer wall structure, uniform grain distribution and reduced internal defects. These properties enhance high-temperature strength and long operational life.
Casting Requirements
| Parameter | Requirement |
| Tube Length | 2 – 6 meters (customizable) |
| Diameter Range | 100 mm – 1200 mm |
| Material Grades | HK40, HU, 25Cr35Ni, Heat Resistant Alloys |
| Operating Temperature | Up to 1100–1200°C |
| Wall Thickness Control | Uniform centrifugal distribution |
