Rotary kiln electric furnace nickel

Apr 13, 2021

Electric heating rotary kiln heated by alloy furnace wire heater. The heating elements of the electric rotary kiln use nickel-chromium alloy (1Cr18Ni9Ti or Cr25Ni20Si2) or iron-chromium aluminum alloy (0Cr13A14 or 0Cr25A15) to make spiral heating elements, which are generally installed on both sides and bottom of the electric heating rotary
