Large deformation in the energy-absorbing unit of a multi-row steel pipe structure under explosive loading is of great significance to the design of an explosion-resistant energy-absorbing unit.

Microstructure and properties of an MoSi_2 heating element modified by ceramic compound;

The content and microstructure of scale of Kanthal Super 1700 MoSi2 heating element were studied using scanning electron microscope(SEM) with energy dispersive spectrometer(EDS).

Based on the X-ray diffraction analysis(XRD),scanning electron microscope(SEM) with energy dispersive spectrometer(EDS),the composition and microstructure of Riken MoSi2 heating element after high-temperature application was studied.

By using CFD software FLUENT,numerical simulation for the three-dimensional flow of air between honeycombed plate heat transfer components is carried out.

Homogeneously heating can be obtained by employing the steel tiles as thermal balance medium in horizontal roller track style tempering oven and the steel tile can also act as a protector of heating element.

A trapezoid heating element used in plate film evaporator was presented in this article.

In the paper,the authors analyse the damage reasons of traditional Ni Cr Heating elements,and introduce both the advantages and the economic effects of adopting silicon carbide rods as heating elements.
