Metal Heat Treatment Equipment Furnace for Non-Ferrous Metals (PMR,RAV)

Recommended Thermal Standard Series of Heat Treatment

Furnace for Non-Ferrous MetalsPMR and RAV

With advances in the mechanical precision of electronic and precision machinery parts, heating in a clean gas atmosphere has become an important requirement. HIROCHIKU's PMR and RAV are primarily used as clean heating furnaces for electronic parts made of copper alloys.

Target Works (Typical Examples)

Heat Treatment Methods

Solution heat treatment, annealing, age hardening, etc.

Examples

Non-Ferrous metals such as copper, aluminum and titanium alloys undergo heat treatment processes such as solutionizing, annealing and age hardening in a protective atmosphere such as hydrogen gas, nitrogen gas and argon gas.
This system is used in a wide variety of areas including contacting materials (such as connector parts), eyeglass frames, fashion accessories and automobile and aircraft parts.

Features

Since the inside of the furnace is evacuated first, oxygen and moisture are removed, enabling heat treatment in a protective atmosphere.

Evacuation enables great savings in the amount of atmospheric gas.

Hydrogen gas can be added depending on the target work type. In such cases, a separate safety circuit is required.

The heat circulation structure using an agitating fan achieves excellent temperature distribution.

PMR Pit Type (Vertical Type) Bright Annealing Furnace

The operating temperature of the PMR is 200 to 750℃, and its treated weight (gross) is 400 to 2,000 kg/charge.
After treatment, the work is left as is so that it slowly cools. Quick cooling with the gas circulation method using a heat exchanger is also available.

RAV Horizontal Type Vacuum Purge Bright Heating Furnace

The operating temperature of the RAV is 100 to 650℃, and its treated weight (gross) is 50 to 500 kg/charge.
The RAV has a programmed heating function and a mechanism for forced cooling after heating, enabling efficient unattended operation.
