Is there any thing about heat treatment
we can do for you?
I want to shorten delivery time.
It decreases some steps (before,after)
because of having little distortion.
You can do heat treatment whenever you want.
I want steady quality.
You can heat-treat your products with your
You gain knowledge of heat treatment.
I want to reduce the cost.
Reduction of processing steps
(before,after) makes processing cost low.
What kind of process
does your company want to do?
Utility and Incidental Facility
- Cooling water
- Furnace is double structure of mild steel and its
intermediate part is cooled by water.
Vacuum device is cooled as well.
- Emer-gency water
- Reserve-water for the time when the passing
water is cut off.
- Cooling gas and partial gas.
- Due to drive of each driving cylinder
- heater, Vacuum device, Control panel
Primary side Nitrogen gas recommended supply system
1 High purity gas bomb
- Arranged in parallel and supply
- Use high purity gas of 99.999%
- Exchange a few bombs at the same time
2 Vaporizer + ELF bomb
- Combine vaporizer and liquefied nitrogen bomb (ELF) and supply.
- Exchange bomb
3 Vaporizer + liquefied nitrogen tank lorry
- Combine vaporizer and liquefied nitrogen tank and supply.
- Supply liquefied nitrogen to liquefied nitrogen tank directly.
※Please consult with professional about filling frequency and
size of supply facilities.
※Buffer tank is needed for all supply system.
Cleaning method Comparison table
Vacuum furnace is relatively weak in the dirt.
Please clean work pieces before throw it into the furnace in order to use long term.
1 Cleaning spray
- Spray cleaning solution directly to the work pieces.
- Wipe cleaning solution with wes and remove it completely by Air.
- Increases labor’s work because of cleaning work pieces one by one.
- It may have fine places where is difficult to clean completely because of work by hands.
- Price is inexpensive because of using only spray.
2 Simple cleaning machine (Ultrasonic)
- Put work pieces into cleaning solution directly, then its dirt has lost touch by ultrasonic.
- Remove cleaning solution by wes and Air after putting work pieces out.
- It is possible to clean fine places in order to put work pieces into cleaning solution directly.
- Cleaning solution must be exchanged or liquid wastes regularly.
※Due to lead to reduce cleaning ability.
- Cleaning equipment is inexpensive to buy.
3 Vacuum cleaning machine
- Set work piece on jig and throw into cleaning machine. It cleans it in full automatic.
- Doesn’t need to remove cleaning solution because it completes drying it out.
- It is needed that cleaning solution supply and disposal of waste liquid.
- By interlocking with another equipment, it is possible to make all heat treatment automatic.
- Cost for equipment is needed as same as vacuum furnace.
- It may difficult to set up because of fire service act.
- Vacuum cleaning machine loads high efficiency distillation regenerator, and it recycles cleaning solution.
