Electric furnace, heating chamber with electricity as the heat source for achieving very high temperatures to melt and alloy metals and refractories. The electricity has no electrochemical effect on the metal but simply heats it. Electric furnaces produce roughly two-fifths of the steel made in the united states. They are used by specialty steelmakers to produce almost all the stainless steels, electrical steels, tool steels, and special alloys required by the chemical, automotive, aircraft, machine-tool, transportation, and food-processing industries. Electric furnaces also are employed, exclusively, by mini-mills, small plants using scrap charges to produce reinforcing bars, merchant bars (e.G., angles and channels), and structural sections. The german-born british inventor sir william siemens first demonstrated the arc furnace in 1879 at the paris exposition by melting iron in crucibles. In this furnace, horizontally placed carbon electrodes produced an electric arc above the container of metal. The first commercial arc furnace in the united states was installed in 1906; it had a capacity of four tons and was equipped with two electrodes. Modern furnaces range in heat size from a few tons up to 400 tons, and the arcs strike directly into the metal bath from vertically positioned, graphite electrodes. Although the three-electrode, three-phase, alternating-current furnace is in general use, single-electrode, direct-current furnaces have been installed more recently.

Lance tip is associating with the central iron and steel research institute, we can optimize the lance nozzle by your steelmaking practice. This would be suitable for your high-efficient oxygen blast demand and shorten the time of blowing, then you will get a better steelmaking efficient. The nozzle produced by the technology of vacuum casting has high-density organization with high copper purity, good thermal conductivity and long service life. With reliable welding technology of copper, and steel, the products, adapt to high temperature and high strength working conditions. The life of the nozzle used at the 250t bof of the second plant of baosteel increases by 30% than that the ordinary nozzle. The assembled nozzle made by forging has the properties of closely grain, high-density organization, high temperature resistance and strong resisting fatigue. By optimal designing the nozzle's inside passage of cooling water, the passage has smaller water resistance and good cooling effect.
We provide the clients with comprehensive and high-quality products by our exquisite and perfect technologies and offer specialized service support by highly efficient and rapid response capabilities, so as to spare no efforts in creating the utmost scientific and technological values for the clients. We sincerely hope that we can get ;;win-win;;¨¤ ending with insightful men from home and abroad hand in hand.
1200c muffle furnace is a ce certified high temperature furnace using high quality ceramic fiber board and resistance wire heating elements. The temperature of 1200c muffle furnace is controlled by high precision controller with accuracy +/-0.5 c and 51 segments programmable up to 1200c. This type of furnace is widely used for materials or chemical lab to sinter all types of new materials samples. It is an ideal box furnace for sintering high purity ceramic material at high temperature without element contamination. Muffle furnace features: 1) three sides resistance wire coil for fast and uniform heating serve as heating element 2) maximum energy efficiency is achieved by surrounding the chamber with thermal-efficient high purity alumina fiber ceramic insulation. 3) double layer steel case with air cooling to ensure low surface temperature 4) design of sliding down door is for loading materials easily 5) furnace chamber: 250x320x450mm 6) built in precision digital temperature controller is 51 segments programmable to control heating rate, cooling rate and dwell time. Temperature control unit can be separated from furnace, and make moving at easy. 7) the furnace temperature is controlled by precision scr (silicon controlled rectifier) digital controller with accuracy +/-1c and 51 segments programmable up to 1200c Muffle furnace applications 1.
