Description

Technical Field

[0001] The utility model relates to the technical field of steel strips, in particular to a cold-rolled longitudinally cut steel strip. Background Art

[0002] Steel belt is a narrow and long steel plate produced by various steel rolling enterprises to meet the needs of industrial production of various metal or mechanical products in different industrial sectors. The conveyor belt made of carbon steel is used as the traction and carrying component of the belt conveyor.

[0003] Cold-rolled steel strip is made of hot-rolled coil and rolled at room temperature below the recrystallization temperature. Cold-rolled steel has good performance, that is, through cold rolling, a thinner and more precise cold-rolled steel strip can be obtained, with high straightness, high surface finish, and easy coating and plating. When the steel strip is in use, the staff usually cuts the steel with a handheld cutting machine. Due to the high surface finish of the existing steel strip, manual cutting is prone to cutting deviation, and the existing cold-rolled longitudinal cutting steel strip is not strong enough.

[0004] For this purpose, we propose a cold-rolled longitudinally cut steel strip. Utility Model Content

[0008] The body comprises a first steel strip and a second steel strip, wherein the first steel strip and the second steel strip are connected by welding connection columns.

[0009] Furthermore, the aluminum layer is provided in two groups relatively parallel to each other, and the first steel strip-shaped body and the second steel strip-shaped body are both provided relatively parallel to the aluminum layer.

[0010] Furthermore, one side of the first steel strip and one side of the second steel strip are both fixedly connected to one side of the aluminum layer.

[0011] Furthermore, the first steel strip is provided with a first through hole, and the second steel strip is provided with a second through hole.

[0012] Furthermore, the first through holes are connected to the second through holes, and a plurality of groups of the first through holes and the second through holes are equidistantly arranged.

[0013] Furthermore, one end of the welding connection column is located in the first through hole, and the other end of the welding connection column is located in the second through hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects: through the design of the aluminum layer, the rust-proof and corrosion-resistant performance of the cold-rolled longitudinally cut steel strip can be improved; through the design of the first cutting dotted line and the second cutting dotted line, it is convenient to cut the cold-rolled longitudinally cut steel strip; through the design of the first steel strip and the second steel strip, the strength of the cold-rolled longitudinally cut steel strip can be improved; the first steel strip and the second steel strip are fixedly welded to the welding connecting column, so that the first steel strip and the second steel strip can be tightly connected.
