First why we need debinding in a sintering vacuum furnace ? After debinding machine there are still 2-3wt% high temperature binder in the products to keep it’s shape.so the first step of sintering furnace it to remove these rest binder(<600 degree).
The electric arc furnace has stronger ability in dephosphorization desulfuration and deoxidation than induction furnace. The slag in induction furnace is cold; furnace slag temperature is maintained by molten steel. Electric arc furnace has the hot slag that is heated by electric arc furnace
Usually, the vacuum graphite furnace is divided into three kinds: low-temperature graphite vacuum furnace, medium temperature graphite vacuum furnace, high-temperature graphite vacuum furnace .
Ceramic blanket suits for what kind of industrial furnace insulation
Thermal conductivity of ceramic blanket is only a quarter of the traditional heavy refractory, which makes ceramic blanket has a rising demand.Improving the technology of production equipment requirements more extensive use of ceramic fiber material in order to improve the technological content and level of light furnace kiln lining. Below to learn what kind of industrial vacuum furnace ceramic blanket can be used in also product advantages.
The heat treating process alters the alloy distribution and transforms the soft matrix into a hard matrix capable of withstanding the pressure, abrasion and impacts inherent in metal forming. Each step of the heat treating cycle is designed to perform a specific function, and, like links in a chain, the final product is only as good as its weakest component. Although it may only represent 10% or less of the cost of the tool, the heat treat process is probably the single most important factor in determining the performance of a tool. There is no such thing as an acceptable shortcut in heat treating tool steels.
It’s difficult to say how long a sintering furnace should last, or even how long it should run before needing repairs. There are things you can do to extend longevity of both the furnace and the components, such as heating elements and thermocoupler.
In the heat treatment furnace, whether the furnace lining’s material is reasonable or not, will affect the heat storage loss and temperature speed directly as well as furnace’s service life.
A vacuum furnace is a type of furnace that can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering and heat treatment with high consistency and low contamination.
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.
