Sintering is a process in which solid wastes are combined into a porous mass that can then be added to the blast furnace These wastes include iron ore fines, pollution control dust, coke breeze, water treatment plant sludge, and flux
The process of causing a mixture of materials to become a coherent mass by heating without melting See fritting
The bonding of adjacent surfaces of particles in a mass of powders, usually metal, by heating
Fusion of a spirally applied tape wrap jacket by the use of high heat to a homogenous continuum Usually employed for fluorocarbon, non-extrudable materials
Heating fine particles below the melting point to cause adhesion and densification
the formation of a solid mass by heating to the point of fusion, but without complete vitrification
densification of a particulate ceramic compact involving a removal of the pores between the starting particles (accompanied by equivalent shrinkage) combined with coalescence and strong bonding between adjacent particles
The generalized process by which high surface area materials lose surface area without melting
The welding together of powdered particles of a substance or mixture by heating to a temperature below the melting-point of the components The particles stick together and form a sinter
Welding together of small particles of metal by applying heat at temperatures below the melting point. The process is used to form complex shapes, to produce alloys, and to allow work on metals with very high melting points. Sintering is also used in the preliminary molding of ceramic or glass powders into forms that can then be permanently fixed by firing. See also powder metallurgy
The process of holding powders or granules at jus: below their melting point; the particles are then fused or stuo together but not melted
A process in which a finely divided ore is heated until it collects to form larger particles
A process where the temperature of PTFE is raised to the point where PTFE particles soften and form a bond with each other
The heating of a mass of fine particles (eg lead concentrates) below the melting point, causing agglomeration to form larger particles
{i} process of heating a material to just below the melting point so that it forms one solid mass
Fusion of a spirally applied tape wrap jacket by the use of high heat to a homogeneous continuum Usually employed for fluorocarbon, non-extrudable materials
One form of agglomeration of fines (iron ore fines, flue dust, mill scale, limestone and dolomite fines) produced by Mines and Steel Plants, by heating at lower temperature till clinker like aggregate is formed which is well suited as a blast furnace feed Skelp Steel that is the entry material to a pipe mill It resembles hot-rolled strip, but its properties allow for the severe forming and welding operations required for pipe production
A porous deposit formed in hydrothermal areas by the precipitation of amorphous opaline silica from silica-saturated waters erupted from geysers and derived from hot springs
Heat and press powder to form a solid object Powder is heated to a temperature below its melting point The combination of heat and pressure weld the individual particles into a strong solid
Any form of of hot spring deposit regardless of chemical composition See also siliceous sinter Sinter deposits form the characteristic gray rock formations seen in the geyser basins
v. Mineral deposit with a porous or vesicular texture (having small cavities). Siliceous sinter is a deposit of opaline or amorphous silica that occurs as an incrustation around hot springs and geysers and sometimes forms conical mounds (geyser cones) or terraces. Calcareous sinter, sometimes called tufa, calcareous tufa, or calc-tufa, is a deposit of calcium carbonate
