Understanding Sinter and Sinter Plant Operations. Sintering is a process of agglomeration of fine mineral particles into a porous and lumpy mass by incipient fusion caused by heat produced by combustion of solid fuel within the mass itself. The sintering process is a pre-treatment step in the production of iron, where fine particles of iron ...
We have developed a number of pre-processes for sintering that contribute to cost and effort reduction of the overall process. These include hot mounting or tacking of semiconductors, but also dispensing of sintering paste and force-controlled placement of semiconductors or modules on heat sinks. These processes can be adapted to …

Basic sintering technology. The sintering technology is basically an agglomeration process for the iron ore fines which is dependent on heat to melt the surface of the smaller particles together to form larger …
Sintering. Sintering is the process of densification, where diffusion of particle surfaces take place and metal parts begin to bind together, closing off the voids where the binder material previously was. The part shrinks between 15-20% (linearly). There are 3 main stages of sintering: presintering, intermediate sintering, and final sintering.
Prevents volatile evaporation and undesirable interdiffusion due to short sintering time, unlike conventional sintering, Allows general and rapid synthesis and sintering of a broad range of ceramic (and metallic) materials by decoupling intrinsic properties of the material (such as the electric response) from the process, unlike flash …

Put your empty microwave kiln in the microwave. Run the microwave at lower power for 5 minutes, then test the temperature of the microwave kiln. Then do all of that again at medium power, then again at high power. As of this writing, the only material that has been debound and sintered using this method is Aluminum 6061 Filamet™.
Sintering 2 2.1 Introduction Sintering is a process that consists in the thermal agglomeration of a mixture of ... obtaining a preagglomerated product that is then fed to sintering machine, ensuring a suitable sinter bed permeability and thus improving the productivity of the sinter plant. † Fernández-González et al.

FGR sintering is the best available technology for use in the integrated iron and steel industry and it has already been applied in commercial sinter plants. However, …
Shrinkage, grain growth, dimensional changes and homogenization during liquid phase sintering of ceramics or metallic systems, are influenced by the presence of additives. Additives are intentionally added to control the microstructural and dimensional development during sintering. Additives may be present in solid state only or may form liquid ...
The emissions are reduced of 6 kg/t- (31%) sinter with a reduced electricity consumption of 8 MJ/t-sinter. In a plant in Ijmuiden with 1.2 MNm3/h of waste gas flow, the investment cost was €17 million with a payback time of 5 years. A similar plant named LEEP was developed and realized (Jeong et al. 2017 ).
Sinter quality begins with the mined iron ore and the proper selection and mixing of the raw materials. Inhomogeneous raw mix can affect permeability and cause an increase in fuel consumption. During the iron ore sintering process in iron and steel manufacturing, an online analyzer can be used to determine the elemental composition …

1. Introduction. The energy consumption in sintering process is about 10%–15% of the total energy consumed in iron and steel companies in China [1], [2], and nearly 50% of the energy consumption in sintering process is carried away by the flue-gas in sintering process and the waste gas in cooling process.Therefore, recovering the …
This paper gives an overall review of a variety of technologies developed worldwide to tackle the changing raw material characteristics and mitigate emissions from sintering operations. Given the high sinter usage and volume of their blast furnaces, most of the recent sintering technologies have originated from East Asia, particularly Japan.
The bonding material of power semiconductor devices requires high thermal durability, conductivity and reliability. Much is expected from Cu sinter materials for bonding because they can meet these requirements. In this study, we investigated bonding properties, die backside metallization compatibility and reliability of our Cu sinter paste. …

Advantages of Sinter-Hardening. There are a number of benefits of the sinter-hardening process compared with liquid quench-hardening of PIM materials. The need for a secondary quench-hardening treatment is eliminated. The reduced distortion of parts due to the less severe quench leads to better dimensional control.
