What is sintered cementedcarbide (hardmetal)? Tungsten carbide (AKA sintered, cemented carbide) is one of the most important modern tooling material manufactured by a process of powder metallurgy.
Vacuum induction melting is indispensable in the manufacture of superalloys. Compared to air-melting processes such electric arc furnaces (EAF) with argon oxygen decarburization (AOD) converters, VIM of superalloys provides a considerable reduction in oxygen and nitrogen contents. Accordingly, with fewer oxides and nitrides formed, the microcleanliness of vacuum- melted superalloys is greatly improved compared to air (EAF/AOD)-melted superalloys.
Sintering furnaces that contain MoSi2 heating elements DO require maintenance or cleaning cycles. If not performed regularly, it is likely you can have a shift in color of the final product.
SIMUWU has been building heat-treating equipment for the global market. Its furnace designs are based on its heat-treating experience and have been proven through years of service.
Grinding steel ball heat treatment typically includes heating, insulation and cooling processes. These steps connect with each other and can’t be interrupted. Wherein, heating is an important step. There are many heating methods for heat treatment. Charcoal and coal are the oldest heat producer, which are generally replaced by liquid or gas fuels. The electricity application makes temperature control easier and no environment pollution. These heat fuels can be used to heat directly or indirectly by molten salt or floating particles.
Sintering is essentially the same process as that used for traditional die pressed Powder Metallurgy parts and can be done in continuous or batch type furnaces, either as separate units or integrated into a complete production line.
Industrial furnace used aluminum silicate fiber board, if the tensile strength is low, the surface will easily appear crack and wrinkle.This leads to layer and peeling when cutting, the cutting surface is rough, can not be cut into small panel.
The lining of introduction melting furnace is divided into four parts: furnace lid, furnace hearth, throat and and sensor. Especially throat,the most critical position’s refractory material directly affects the life and operating costs of the furnace.
Investment casting requires the use of a metal die, wax, ceramic slurry, furnace, molten metal, and any machines needed for sandblasting, cutting, or grinding. The process steps include the following:
GCr15 Bearing Steel Heat Treatment Is GCr15 bearing steel heat treatment better processed by vacuum gas quenching furnace or vacuum oil quenching furnace? GCr15 bearing steel is a widely used steel, although it is bearing steel, it is also usually used to manufacture cold stamping dies, measuring tools, tap, etc., So it is not appropriate…
