[0002] Angle steel tower is a plate tower with downcomers. Its bubbling area is composed of angle steels arranged side by side. The arrangement direction of angle steels is parallel to the direction of liquid flow. The sharp edge of angle steel is at the bottom, and the cross section is "V" shaped. There is a certain grid gap between two adjacent angle steels. The downcomers are the same as general tower plates. During the production process of angle steel tower, a swing shearing machine is needed to cut the raw steel plate.
