Instruction
W steel belt is a kind of new structure material, W steel band using the thickness of 3, 5 mm width 180-320 mm steel plate, after cold bending into a W in the planting distance equal W steel belt in central processing out and bolt anchor hole of steel belt.W steel belt can be combined together with all sorts of all sorts of anchor rod anchor plate bracket, W steel band pass W steel belt scattered dogan anchor link together to form a whole bearing structure, W steel belt is widely used in the coal mine roadway, working face cut, chamber, and other fields of roadway support, to deal with instability of surrounding rock for better efficacy.
Advantage
W steel band and flat steel compared with the technology advantages:
1, W steel band bending section modulus increase 37 times.
2, steel increase about 70 times.
3, W steel belt hardening effect in the process of cold rolling, improve the tensile strength of 12% - 15%.
