The utility model has the beneficial effects that:
Existing cut deal, hot continuous rolling, steekle mill or Equipment for Heating Processing are made full use of, using rolling rear steel plate or strip
Residual temperature directly bends to the fashioned iron for meeting assembled architecture required thickness, expands the supply side product of existing production line, and release is existing
There is the ability of production line；The big thickness fashioned iron of production can be directly used for the steel construction production of assembled architecture, instead of existing steel
The portioned product that the attached production line such as structure factory Cold Bending Production Line and bevel and clod wash cannot achieve is (such as bending circle
Cracking etc. at angle), and then the cost of assembling type steel structure is reduced, improve competitiveness.
Hot bending fashioned iron breaches the limitation on specifications section, can produce all kinds of fashioned iron of big cross section think gauge, fill up this
The blank that class product passes through brake forming；The online roll-in thermoforming production line of hot plate/band is convenient for being arranged in cut deal (furnace
Volume), multiple positions of hot-strip or heat-treatment production line, the production without influencing existing production line is convenient for existing enterprise
Industry undergoes technological transformation.
Any person skilled in the art all can under the spirit and scope without prejudice to utility model, to above-described embodiment into
Row modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the revealed essence of utility model
All equivalent modifications or change completed under mind and technical idea, should be covered by the claim of utility model.
