Technical characteristics and main configuration of hydrogen furnace

---

The hydrogen furnace is mainly used for the heat treatment of tool steel, die steel, high-speed steel, ultra-high-strength steel, magnetic materials, stainless steel, non-ferrous metals and other materials in a hydrogen atmosphere.

Technical characteristics of hydrogen furnace:
1. The furnace body is a horizontal, single-chamber, and horizontal charging structure, and the method of opening the furnace door is set according to user needs;

2. The furnace bladder has been modularized and optimized design, and the furnace temperature uniformity is good;

3. the all-metal heat shield adopts back insulation technology;

4. Multiple working modes of the equipment can be selected: positive pressure hydrogen; negative pressure dynamic balance hydrogen; negative pressure pulse hydrogen;

The main configuration of hydrogen furnace:

1. Opening method of furnace door: online type; offline type; vertical lift type; rotary type;

2. Furnace: composite structure of graphite heating element and graphite felt composite screen; composite structure of molybdenum heating element and full metal heat shield;

3. Vacuum pump set and vacuum gauge: imported; high-quality domestic;

4.vacuum degree: high vacuum, medium vacuum;

5. Hydrogen discharge method: positive pressure discharge, negative pressure extraction;

6. Recorder: paper recorder, paperless recorder;

7. Human-machine interface: analog screen; computer touch screen.

Features

1. The furnace body adopts a square structure, and the columnar structure of the furnace makes the airflow distribution of the cracking tube uniform, and the life is uniform, and the material is made of rare high-temperature heat-resistant alloys to ensure a long time in high temperature and strong corrosive environments. Service life.

2. The heating element adopts nickel-chromium alloy with excellent mechanical properties at high temperature, and its surface load is determined within a reasonable range. And the furnace body adopts a type structure, fast heat transfer, easy maintenance and replacement, and quick.

3. The core insulation material silicic acid fiber is molded by vacuum suction filtration and strengthened on the surface more than five times, so it is light in weight and high in strength; at the same time, its unique structure determines that the heat transfer coefficient of this material is lower than that of similar products.

4. The heat exchanger adopts a tube-in-tube structure, and the larger heat exchange area ensures the full use of thermal efficiency while ensuring a sufficiently long service life.
5. The drying tower adopts a cylindrical structure. Heat is conducted to the inner cylinder through the heating sleeve. At the same time, it has the two effects of air flow medium and cylinder wall to heat the molecular sieve layer. On the one hand, the molecular sieve in the drying tower is heated evenly, while avoiding Local overheating of the heating element.

6. This equipment has the advantages of low investment, low operating cost, simple installation, convenient use and maintenance, and high safety performance. Features such as good adjustment performance.
