Description
Technical field
The invention belongs to machine-building and metal material processing and field shaping techniques, and in particular to a kind of hot rolling decorative pattern H
Shaped steel and its roll and milling method.
Background technology
Hot rolled H-shaped to be used as a kind of novel architecture steel, H profile steel cross sectional shape economical rationality, mechanical property is good, during rolling
On section each point extension it is more uniform, internal stress is small, compared with common I-steel, have modulus of section it is big, it is light-weight, save metal
The advantages of, building structure can be made to mitigate 30-40%；Again because in its leg outside it is parallel, leg end is right angle, assembling combination into component,
Welding, riveting work amount can be saved up to 25%.It is usually used in that requirement bearing capacity is big, good heavy construction (such as factory of cross-sectional stability
Room, skyscraper etc.) and bridge, ship, handling machinery, Equipment Foundations, stent, foundation pile etc..In large-scale, high-altitude
When the construction platform of operation is built, to improve the antiskid effect on surface, generally use welded add again after platform checkered steel plate,
The anti-skidding anti-skid mesh of steel plate etc. modes, increase difficulty of construction and production cost.
Although there is corresponding patent to disclose corresponding solution for channel steel in the prior art, according to respective party
During channel steel prepared by method can be used for the Facilities Constructions such as subway, trestle, parking systems, abrupt slope track, room channel, Yi Ji
Rob and repair roads, build disaster area sidewalk and cover plate of the temporary platform when facilities are constructed of constructing, but for more common and
For the more urgent H profile steel of demand, there is not ripe report but.
At present, the hot rolled H-shaped of domestic production is smooth surface or spends face entirely, in use, if the web of H profile steel
Be smooth surface with wing plate, then there are adhesive force it is too small the defects of, and for entirely spend face it is hot rolled H-shaped, then there are welding difficulties
The problem of.Also, since the application scenarios of these H profile steels have strict requirements for H profile steel, the prior art is in production wing plate
Be all to roll comprehensively during web, and be aided with the overwrought decorative pattern in later stage, currently on the market there is no only with regard to the portion in a face
The situation that subregion is rolled.
