The other one is material can be linear, isotropy or anisotropy, constant or relating with temperature in model analysis[1-3].
Rigid connection method is adopted between the supporting pillar with the main structure beam and strengthen beam of the supporting platform, and hinge node connection is adopted between corner steel constituting a stable system with edge support column and supporting pillar; All steel structure materials adopted in simulation are assumed to rational elastic materials; All steel structure component materials are assumed to linear elastic materials, and meet Hooke’s law, at the same time, in the simulation process Skin effect of steel plate is ignored.
To sum up, it can be seen from the analysis result statistics, all the calculated data is in the safety range of materials allowed, namely, the integral design that the coke powder tank supports platform can satisfy the requirement of production.

Since these conditions are beyond the limits of general fluid lubricant, one have to find new lubricating materials and explore new lubrication method.
The ball-on-disk matches was used and Al2O3 ceramics ball (Φ materials Ra0.05 μm, 1.27 mm) was the up sample, while 1Cr18Ni9Ti austenitic stainless steel disks after laser texturing and plasma molybdenizing/plasma nitriding treatment were used as the lower sample.
When the MoS2 lubricant is added to improve friction and wear properties of materials, especially at high temperatures, the low friction coefficient and wear rate is obtained.
