As a highly automatic H-beam production line, Heavy-duty steel production line sees reducing the use frequency of overhead crane as its subject. Through using automatic machines as roller conveyor, turning machine and conveying machine to conveying, turning and moving H beam during welding process, which greatly improved user’s production efficiency. 

The General production process of heavy-duty steel production line as following:

Strip cutting- strip processing (joint—grooving)—T-beam assembling—H-beam assembling-- beam 90° turning–beam conveying-- beam moving-- beam 45 ° turning—welding by the first cantilever welder at the first welding section-- beam 45°returning – beam moving-- beam 45 ° turning --welding by the second welder at the first section-- beam 45 °returning -- Beam moving-- Beam conveying-- Beam 180 ° overturning-- Beam conveying-- Beam moving-- Beam turning 45°-- welding by the first cantilever welder at the second welding section-- Beam returning 45°-- Beam moving -- Beam overturning 45 ° --welding by the second cantilever welder at the second section  -- Beam returning 45° -- Beam moving -- Beam conveying-- Beam 90 ° overturning—the straightening of one flange -- Beam 180° overturning—the straightening of the other flange—welding of stiffened end-plates-- Beam’s secondary processing(Beam sawing – face milling-- Three-dimensional drilling)—shot blasting—painting.
