When you need a new vacuum heat treatment furnace to start a new project or meet the requirements of a new product, the first question is often the initial investment cost of the equipment. Next is operating costs (operating costs). As a professional manufacturer of vacuum furnaces for various applications, ULVAC would like to offer a few tips.
I. PARTS IN VACUUM HEAT TREATMENT FURNACE:
A vacuum furnace is a type of furnace in which the product requiring heat treatment is placed in a vacuum or inert gas environment with the purpose of preventing oxidation and heat loss from the product during convection, and eliminating pollution sources infected. The price of a vacuum furnace depends on many factors such as materials, quality of the furnace (safety level, tightness, precise temperature control, operating costs, longevity…), furnace capacity, whether provide solutions or transfer technology or not, after-sales service, etc.
Vacuum furnace includes furnace chamber, heating elements, power supply and temperature control system, control system, vacuum generation system, cooling system.
Vacuum system:
- Vacuum furnace chamber includes: stainless steel chamber, ceramic, molybdenum or carbon material chamber. The maximum temperature ranges from 750 ° C to 2200 ° C. With different materials of parts in the vacuum chamber, the price will be different.
- The vacuum generation system includes a vacuum pump system, includes a primary vacuum pump (usually an oil ring vacuum pump), a booster pump and a diffusion pump (if a deeper vacuum level is needed) depending on requirements. bridge with vacuum valve system. The deeper the vacuum, the higher the price.
Control system:
- The temperature control system of a vacuum furnace mainly includes a temperature sensor, a temperature controller and a power semiconductor power supply, usually an SCR (Thyristor). PID algorithm controller (Derivative+linear proportional+integral) controlls temperature and pressure are two parameters. It is very difficult for a vacuum heat treatment furnace to create a uniform heat zone with an error of less than 5 degrees Celsius at a temperature range of 1,000 degrees Celsius. This is solved by Ulvac thanks to R&D research institutes located in Japan.
- PLC and HMI control system:. PLC controlls and monitors all furnace operations . Communication between operator and furnace via HMI.
Cooling system:
- For the cooling system, there are 2 parts. Cool the product with N2 gas and cool the furnace with water. The higher the maximum allowable N2 gas pressure, the higher the furnace price. With a water furnace cooling system, we usually design the water pressure at 1.2-2.0 Kgf/cm2.
- N2 gas supply system (gas tank): depending on the tank’s capacity, prices vary.

The safety factor is something that few manufacturers can guarantee. But we commit to absolute safety when customers use Ulvac vacuum heat treatment furnace products.
Depending on the investment plan and project of each business, it will last for 2-3 years or 10-20 years. Product durability requirements also vary. For ULVAC, we specialize in providing products with furnace lifespans of 20 years or more.
Mechanical breakdowns or errors are sometimes unavoidable. Can be objective or subjective. We heard from some customers about their experiences. When using certain furnace brands that are not as advertised, they often encounter major problems that can only be temporarily fixed, causing immeasurable damage in the future. Real people doing real work right in Vietnam, Ulvac is ready to take you to directly visit factories using Ulvac vacuum heat treatment furnaces to hear from the users themselves.
