Metallurgical furnaces are mostly used for (i) extraction of metals from ores, (ii) calcining and sintering of ores, (iii) melting, refining and alloying of metals, (iv) heating of metals, (v) carbonizing of coals, and (vi) heat treatment of metals etc. Energy sources for metallurgical furnaces are (i) combustion of fossil fuels, such as solid
Description: The TRENT M2-DKR High Temperature Furnace heating elements are silicon carbide type resistors located beneath a ceramic hearth plate, which protects against scale and breakage. The door is vertical lift counterweighted to provide a tight seal with the brick-lined furnace front.
Since the late 19th century silicon carbide has been an important material for sandpapers, grinding wheels, and cutting tools. More recently, it has found application in refractory linings and heating elements for industrial furnaces, in wear-resistant parts for pumps and rocket engines, and in semiconducting substrates for light-emitting diodes.
SiC Elements (Silicon Carbide) Our specialists at Keith Company design electric furnaces and kilns with a wide range of heating element choices. The fundamental operational limitation of any electric heating element is the maximum element surface temperature (MET).

The charge itself acts as the electrical resistance and generates the heat. The resistance furnace is used to melt metals such as ferroalloys at tempera- tures up to 6000 F. 6.13. A crucible furnace consists of a large, covered metal pot lined with refractory materials such as clay-graphite mixtures or silicon carbide.
muffle. Heating and cooling rates of 200-400C per minute were generally encountered and the sintering "times" that are presented are the time intervals that specimens are at the sintering temperature. They do not include the heating and cooling periods. Temperatures were measured with a micro-optical pyrom-eter**sighted directly on the specimens.
SiC (Silicone Carbide) Keith Company uses Silicon Carbide (SiC) elements in many of our high temperature furnaces and kilns. They are self-supporting, which enables them to be used in furnaces and kilns that are too wide or too long to be spanned by metallic or MoSi2 heating elements.
Literature data were used for specific heat of all phases as well as density and thermal conductivity of silicon and silicon carbide. The heat Q generated due to the exothermal reaction of carbon and silicon to silicon carbide is given by: (14) Q = Δ H c A R ∂ δ SiC ∂ t s (δ SiC), where ΔH and c A R are the enthalpy of reaction and the
Silicon carbide fibers can have potentials for a good catalytic support, gas-fueled porous radiation heater, ceramic fiber separators and filtration media for diesel particulate filter (DPF). For those applications, it is increasingly needed to fabricate smaller diameter fibers with an increased specific surface area. [1,2]
