Mainly used in stainless steel and iron-based powder metallurgy injection molding (MIM), hard alloy, high temperature alloys, high specific gravity alloys, cermets, magnetic materials, carbides, borides, oxides, intermetallic compounds, oxides before sintering Vacuum or carrier degreasing (wax).
Configure rapid cooling system, improve product quality, shorten the production cycle, improve production efficiency. Dedicated skim seal furnace gall and grease catcher to reduce the furnace wall, heat shield and heating body pollution, degreasing and fat collection more effective, dedicated seal furnace gall is conducive to improving the uniformity of the furnace. Directional air degreasing, enhanced degreasing effect, degreasing more thoroughly.

HSF Hydrogen Sintering Furnace
Product Features and Special Configuration
Hydrogen furnace temperature
The hydrogen furnace is divided into two types: high temperature hydrogen furnace (HHF) and medium temperature hydrogen furnace (MHF). The high temperature hydrogen furnace is used for powder metallurgy sintering and ceramic metallization. The medium temperature hydrogen furnace is used for welding, annealing, degassing and degreasing. , purification and other processes. The user can fully propose the highest temperature index of the hydrogen furnace according to the process requirements.
Hydrogen furnace heater
The heater has a variety of structures such as tungsten wire, molybdenum wire (belt, rod), graphite rod, etc., and the external heating type adopts ordinary electric heating wire, depending on the maximum temperature required by the user. The heater distribution method has four types of heating type and all-round heating, which ensures the user’s requirement for uniformity of temperature in the furnace.The heating and holding chamber is available in all metal type and composite type. The full metal type is composed of heat-resistant stainless steel and molybdenum screen. The composite type is made of heat-resistant stainless steel, molybdenum screen and carbon felt, mullite fiber or lead silicate fiber. composition. This depends on the user’s process conditions and the requirements of the process environment.
Hydrogen furnace temperature control
The temperature control adopts the imported intelligent temperature controller, which can realize the automatic control function of heating, constant temperature and temperature drop. It has the process curve storage function, can store multiple different process curves, has the adjustable temperature and accurate clock function, and can display at the same time. Various parameters such as actual temperature and set temperature, with PID parameter self-calculation and power-down protection.
Hydrogen furnace heating method
The hydrogen furnace is divided into two types: internal heating type and external heating type according to heating mode. The internal heating type is provided with a heater in the heat insulating layer, and the heater directly heats the workpiece. The external heating type is provided outside the furnace made of a high temperature resistant alloy. The heater indirectly heats the workpiece through the furnace wall, so that the workpiece is no longer contaminated by the volatile materials generated by the heating material and the thermal insulation material, and is allowed to be in any The workpiece is heat treated and thermally processed under a protective atmosphere (including flammable, explosive, toxic gases, corrosive gases), and the maximum temperature is limited by the furnace material.
