GREEN TECHNOLOGY. The manufacturing process of sintered components is certified as ecological, because the material waste is very low, the product is recyclable, and the energy efficiency is good because the material is not molten.
Get PriceThe invention discloses a selective laser sintering (SLS) sintering precoated sand process, which selects 100% of cermic foundry sand as precoated sand, granularity of the selected precoated sand is that the selected precoated sand can penetrate through meshes of 140 70 sizes, and adopt a thermal template shell mould laminating method, wherein the added resin coated sand amount of the precoated sand .
Get Pricesand is not bonded together. Common to almost all forming techniques is the fact that the green body produced has a low density and little to no strength. To increase the density and strength of the ceramic, it goes through a process known as sintering. Sintering is the process of heating the
Get PriceSINTERING PROCESS Sinter making is a method of fusing iron ore fines into larger particles suitable for charging into the blast furnace. Predominant source of iron in many blast furnace processes. This technology was developed for the treatment of the waste fines in .
Get PriceSelective Laser Sintering (SLS) SLS generates a part by selectively bonding Inultiplelayers ofpowder to build a three dimensional part in a layerbylayer manner. The process has been comlnercially applied to ABS plastic, nylon, polycarbonate, and wax[5][6][7]. The process is very appealingfor applicationsinvolving 111etals and ceranlics.
Get PriceThere are two process of agglomeration for iron ore: 1. Sintering 2. Pelletisation Less than 100 mesh fine iron ore is used for sintering whereas more than 100 mesh is used for the pelletisation. Therefore, they are not competitor. They are complimentor of eachother. 2. DEFINITION OF SINTERING: Sintering is a process of agglomeration of fine mineral
Get PriceSintering was carried out on iron and iron‐SiC powder mixture using DMLS machine at laser speed of 50, 75, 100, and 125 mm/s. Microstructure, density and micro hardness studies were carried out on the sintered specimens.
Get PriceSintering of Iron Ores in a Millipot in Comparison with Tablet Testing and Industrial Process Abstract To explore the feasibility of smallscale sintering pot testing, a 'millipot' facility (diameter of 53 mm and height of 400 mm) was established and used to examine the sintering performance of iron ores and other nontraditional ferrous materials.
Get Pricesimulation of the sintering process that is dominated by grain boundary diffusion, which is recognized as one of the dominating sintering mechanisms. Specifically, a viscoelasticity model that accounts for the microstructural grain growth has been developed to simulate the thermal induced creep deformation in sintering. Sintering stress
Get PriceOutotec Traveling Grate Sintering is based on our extensive experience and continuous RD in fineore preparation and agglomeration. The process is suitable for sintering a wide range of raw materials, including iron, manganese, and nickel ores. Our innovative technologies, including industryleading process automation
Get PriceThe sintering process converts finesized raw materials, including iron ore, coke breeze, limestone, mill scale, and flue dust, into an agglomerated product, sinter, of .
Get PriceIronbase P/M parts can be infiltrated with copper or a copper alloy by placing slugs of the infiltrant (which has a lower melting point than the porous body) on the compact prior to sintering. Upon melting, the infiltrant is completely absorbed as a liquid into the pores by capillary action to produce a component with a composite structure.
Get PriceFeb 28, 2001· Sintering: Sintering is the process whereby powder compacts are heated so that adjacent particles fuse together, thus resulting in a solid article with improved mechanical strength compared to the powder compact. This "fusing" of particles results in an increase in the density of the part and hence the process is sometimes called densification.
Get PriceABSTRACT: The role of gas constituents in a sintering atmosphere is reexamined in order to optimize sintered properties of ironcarbon powder metal (PM) components. Property variations in sintered products are related to hydrogen concentration and dew point inside sintering zone.
Get PricePowder metallurgy uses sintering process for making various parts out of metal powder. The metal powder is compacted by placing in a closed metal cavity (the die) under pressure. This compacted material is placed in an oven and sintered in a controlled atmosphere at high temperatures and the metal powders coalesce and form a solid.
