Open plate is a steel plate originally produced by a steel factory as a steel strip with a certain thickness and width, which is rolled according to user requirements. The original flat plate is rolled to the size required by the national standard when it leaves the steel factory. Generally, the original flat panel has strict dimensions, good performance, and high prices. Opening a tablet is relatively cheap, with slight variations in size.
The flat plate and the original flat plate should be respectively referred to as shear steel plate and single rolled steel plate. When the steel plate comes out of the steel mill, it is rolled into coils. The flat plate after these steel plates are flattened by the machine is called "open plate", just like the entire roll of toilet paper. The internal stress level of the flat plate is high, so the dimensional stability is poor.
advantage
1、 The price is cheap and the length can be freely determined;
2、 Convenient transportation without considering the size of the steel plate;
3、 Easy to cut, can be cut according to the actual size of the steel plate needed;
4、 It can effectively save materials. For example, a certain storage tank requires 6800 × one thousand and five hundred × There are 20 steel plates of 6, and the market steel plate sizes are generally 6000, 8000, and 9000 lengths. If market steel plates are used, there will be small leftover materials. By using a flat plate, 6900 steel plates can be directly used, saving materials, which is also the biggest advantage.
The disadvantage is that there will be significant welding deformation during welding, making it difficult to adjust. Therefore, components with high requirements for appearance quality cannot use split plates.
