98.3---99.9% MgO Magnesia ceramic pipes tubes pin rod for cartridge heater


Description:


1) The product is ued in controllable aural various heat treatment furnace,to avoid the contact of elding burning outcome or to avoid the corrosion of furnace gas to heating element.The process(the conversion of elding burning or electric energy) is put into refractory steel tube and let amount of heat radiate by wall of tube.This device is called as heater tube.


2) Electrothermal heater tube will close the heating element in the jacket,after electrify and heat up,the heat is indirectly radiated to furnace liner and workpiece to be heated by bushing.The heat up of heater tube is used in furnace with going protecting aural and corrodent aural,such as continuous furnace,roller furnace, pit furnace.

..

Specification:


The material of tube:
The electrothermal alloy material that heating tube apply should be of higher resistance rate.The percent conversion of galvanothermy is high.Because the heating tube is put in the bushing,the process of heat transmission is different from that of open type heating element.Its heat shield is big.The temperature of element must be controlled at the course of temperature rise,to avoid temperature excursion of element.

When the heater tube is closed and heated,the surface temperature of heating element is higher roughly than temperature of hearth by 100 C~150 C.So temperature of furnace and atmosphere of temperature of furnace are needed to analysed.Choose correct heating material.

The heater tube produced by gongtao company often apply Cr20Ni80,Cr25A15,Cr21A16Nb,Cr27A17Mo2 ect.
