What does "welding H" steel set "vertical" and "corrective processing" mean?
The steel plant produces H steel with a special machine to process a 500*300*12*10 H steel of a length of 12 meters
Since the H steel web needs to be machined is 10 thick, it can be easily welded to the submerged welding machine, so there is no need to break the seamAfter blanking, use the crane to lift the plate to the erection machine one by one, and clamp. Start the set, set the machine, adjust the position of the three plates, and fix the spot weldingNote: the assembling machine is specially used to assemble the H steel machine, three plates, processing it can clamp type H steel H steel will start the machine, by the end of the assembling machine to roll to the other end, through assembling the machine when the door frame, can be used to adjust the assembling machine accurate three plate position, is a period of adjustment of rolling.After erection, the crane is welded to the welding platform and submerged arc weldingAfter welding, lift to straightening machine for straightening and correctingNote: the straightening effect correction principle: after welding flange may be not perpendicular to the web, using roller flat. Because H type steel may also be in the length direction is not straight, also can use the pressure roller is adjusted. The general steel processing plant of the straightening machine only in H flat slab steel width flat with length up straight. Straight up the length function of flame correction, flame correction, H steel with roasted curved, roasted red with water, due to thermal expansion and contraction, H type steel straight up. But it must have some experience to master the operation.
According to the need of the project, can buy coil, coil length can be determined according to needs, here, flat, 12 meters long can be under the requirements of course, can also set foot flat, if you buy the flat plate is 9 meters *2 meters, is the longest length of only 9 meters, making H steel 12 meters long, feeding after docking, if the butt, butt joints need to stagger.
