To densify by heating without complete melting.
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.
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.
A process of forming a coherent mass of material by heating without melting.
the process of combining/fusing metals, (usually with pressure and temperature) by exposing them to a temperature just below their melting point – usually used to “fire in” Nickel plating
