Radiation tube

Radiant tubes—used in our company’s heating furnaces—come in three types of inner heating cores: Cr20Ni80, rare-earth alloy, and FeCrAl. As for the outer casing manufacturing processes, we offer three options: rolled-plate welding, seamless tubing, and centrifugal casting, ensuring that we can meet a wide range of customer needs. Depending on the material, radiant tubes are covered by a warranty period of 1 to 2 years.

Oxygen probe

Oxygen probes: Our company uses Oriental oxygen probes, an imported brand from Japan. These probes offer precise measurement of carbon potential inside furnaces, are easy to install, and boast a long service life. Available models include: OS-650, OS-750, OS-850, and OS-950. The oxygen probe warranty period is 1 year.

Thermocouple

Thermocouples—Our company uses thermocouples that offer accurate temperature measurement, simple installation, and convenient maintenance and upkeep. We provide thermocouples for various applications, including furnace temperature-control thermocouples, overtemperature-monitoring thermocouples, and thermocouples for general temperature measurement. (Available in both domestic brands and U.S.-imported brands.) Thermocouples come with a one-year warranty.

Material tray and tooling

We offer two types of material trays and tooling: heavy-duty reinforced trays and lightweight, energy-efficient trays. For customers with high production volumes and frequent furnace loading, we recommend the heavy-duty reinforced trays, which have a relatively longer service life. For customers with lower production volumes and lighter products, we suggest the lightweight, energy-efficient trays, which feature a faster furnace heating rate, lower energy consumption, and a more affordable price. The manufacturing processes for these trays and tooling include precision casting and silica sol investment casting, both of which come with a one-year warranty. We also provide customized services for material trays and tooling.

Stirring fan

Agitator fans—Our company uses integrally cast agitator fans, available in two material options: Cr25Ni20 and Cr25Ni35. The warranty period for agitator fans made of Cr25Ni20 is 1 year, while the warranty period for those made of Cr25Ni35 is 2 years.

Cylinder seal ring

Pneumatic Components: Our company uses pneumatic components such as solenoid valves and cylinders from two brands—CKD and SMC—and offers a one-year warranty period.
