Electric Ceramic Bobbin Radiant Heater for Industial Furnace
Electric Ceramic Bobbin Radiant Heater for Industial Furnace
Product manual
The inner core of the electrothermal radiant Heater is composed of a U-shaped axially arranged end-welded resistance wire and a ceramic support frame, and the inner core and the outer protective sleeve are not shielded, and the heat dissipation is good. The electric radiant tube with rated working temperature of 1000 degrees, the material of the resistance wire is Cr20Ni80 or 0Cr21Al6Nb, the surface working temperature can reach 1200 degrees, the maximum working temperature of the electric radiant tube with this material can reach 1000 degrees, and the support frame is corundum ceramic parts. The outer protective sleeve is a cold-drawn seamless thin-wall heat-resistant steel tube. The material is 1Cr25Ni20Si2 or 1Cr25Ni35Si2. The material has good high temperature oxidation resistance, high temperature creep strength and certain anti-carburization performance. The radiant tube design and material selection safety factor Larger.
The electric radiant Heater with rated working temperature of 1200 °, the material of the resistance wire is 0Cr27Al7Mo2 or steel flower HRE, the surface working temperature can reach 1400 degrees, the maximum working temperature of the electrothermal radiant tube with this material is 1250 degrees, and the support frame is steel jade porcelain. Pieces. The outer protective sleeve is a cold-drawn seamless thin-walled heat-resistant steel tube. The material is Fe-Ni-Cr-Al-Re alloy. The material has ultra-high oxidation resistance and can work for 1300 degrees in an oxidizing atmosphere for a long time. Oxidation.
