Sinter

Concept of sintering: the process of mixing and pelletizing all kinds of powdery iron bearing raw materials with proper amount of fuel and flux, adding proper amount of water, making a series of physical and chemical changes in the materials on the sintering equipment, and bonding the mineral powder particles into blocks.

At present, the belt type suction sintering machine is widely used to produce sinter. The technological process of sintering production mainly includes the preparation of sinter, batching and mixing, sintering and product processing.

The sintering cup in the workshop of Metallurgical Building is equipped with leaf type 5 fan, high-efficiency ignition system with national patent, high combustion temperature, wide adjustment range, high-efficiency barrel mixer with adjustable rotation speed, filling rate and time, which can carry out sintering experimental research under different negative pressure, different material layer height and other conditions, and can also be used for different ignition temperature, ignition strength and hot air burning The experimental research work of sintering can also effectively simulate the production and complete the research work of mixture mixing and granulation in sintering experiment.

The service of iron ore powder sintering can be carried out.

Hot pressing sintering

Hot pressing sintering is a kind of sintering method which fills the dry powder into the model, and then heats it from the uniaxial direction while pressing, so that the forming and sintering can be completed simultaneously.

The vacuum tungsten wire two-way hot pressing furnace of special ceramics powder metallurgy research room is vertical periodic operation type, which can be used for functional ceramics, cemented carbide and powder metallurgy materials to carry out hot pressing sintering or hot treatment under the condition of high temperature and vacuum or under the condition of inflation protection (non carbon and nitrogen elements).

External service: 300 ℃ ~ 2000 ℃, no volatilization vacuum degree of material is required to reach 5 × 10-3pa

SPS by spark plasma sintering

Spark plasma sintering system (SPS)

It is a new technology for the preparation of functional materials. It has the distinct characteristics of fast heating speed, short sintering time, controllable structure, energy saving and environmental protection. It can be used to prepare metal materials, ceramic materials, composite materials, nano block materials, amorphous block materials, gradient materials, etc.

Sintering atmosphere: atmosphere, vacuum or shielding gas (AR) maximum sintering temperature: 1700 ℃ heating rate: about 100 ℃ / min
