What is sintering process PDF?
Sintering is a thermal agglomeration process that is applied to a mixture of iron ore fines, recycled ironmaking products, fluxes, slag-forming agents and solid fuel (coke).
What is sinter used for?
Sinter is the primary feed material for making iron and steel in a blast furnace.
What is sinter in steel?
Sintering is defined as the agglomeration of the Iron ore fines (generally <8 mm) by incipient fusion of fine mineral particles with heat produced by burning of coke breeze, uniformly distributed in raw mix bed.
Why sinter is used in blast furnace?
Processing sinter helps eliminate raw flux, which is a binding material used to agglomerate materials, which saves the heating material, coke, and improves furnace productivity.
What are the types of sintering?
Basically, sintering processes can be divided into two types: solid state sintering and liquid phase sintering.
What are steps of sintering process?
ChinaSavvy’s metal sintering process, also commonly known as the powder metallurgy process, is divided into three main steps: Blending. Compaction.

What is the sintering temperature?
The densification or sintering temperature of the LTCC should be less than 950°C since the common electrode material, Ag, melts at 961 °C. In the case of Cu- or Au-based electrodes, the sintering temperature should be less than 1050°C.
What are the different types of sintering?
What is sinter made of?
Sinter is the primary feed material for making iron and steel in a blast furnace, and is made by mixing iron ore concentrate with several additives (such as limestone and silica to control the chemistry) and then igniting it at 1200°C in a continuous belt-fed furnace.
What is sinter process?
Sintering is a thermal process of converting loose fine particles into a solid coherent mass by heat and/or pressure without fully melting the particles to the point of melting.
