Four factors affecting the sintering of refractory materials

The sintering of refractory materials is a complex process that is restricted by many factors. The main factors that affect the sintering of refractory materials include the nature of the raw materials, additives, sintering temperature and holding time, firing atmosphere, and molding method and pressure of the green body.

Refractory sintering

Unshaped refractory materials in the process of gradually sintering. From a process point of view, sinter is a sturdy, low porosity (almost airless 7L) stone made from a powder at high temperatures. Refractories degree of flexibility of the signs, usually with the object size reduction (the so-called shrinkage), reduced porosity and bulk

J.L. Johnson, in Sintering of Advanced Materials, 2010 14.4 Sintering methods. High sintering temperatures are generally needed to process refractory metals due to their high melting temperatures, but specific conditions depend on the particular alloy, particle size and impurities.

Sintering or reaction sintering process for ceramic or

We claim: 1. A process for sintering ceramic or refractory materials wherein the improvement comprises injection of a combined primary plasma arc gas with a secondary colder gas from at least one plasma arc torch, directly into at least one gas port of a furnace, said secondary gas being injected into said plasma arc gas tangentially, thereby creating a swirl effect wherein the secondary gas

Refractory Manufacturing

Refractory materials form the crucial interface between the units of thermal process technology and the material to be heated. Their functionality influences the product quality as well as the cost of the heat processes. Refractory materials have to comply with the highest quality standards in critical application areas, such as metal, glass and ceramic production.

Sintering: A Step Between Mining Iron Ore and Steelmaking

Jun 11, 2019 Sintering: A Step Between Mining Iron Ore and Steelmaking. The USGS defines iron ore as a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). It’s a major ingredient in steel.

The Sintering Process of Iron Ore Fines IspatGuru

Mar 09, 2013 Sintering process helps utilization of iron ore fines (0-10 mm) generated during iron ore mining operations. Sintering process helps in recycling all the iron, fuel and flux bearing waste materials in the steel plant. Sintering process utilizes by product gases of the steel plant.

The Sintering Process in Powder Metallurgy GE Additive

The sintering process takes place in furnaces that cool materials at a rate consistent with the creation of martensitic, crystalline structures. At first, discrete particles remain because complete compaction or melting does not occur. In powder metallurgy, the selected sintering temperature is always lower than the melting point of the primary
