Hot Rolled Plate Sizes

In order to improve the corrosion resistance and decoration of extra thick and medium plate processing and cutting, electroplating or coating protective layer on the processing surface of plastic medium and heavy plate has become electroplating and coating steel, which is also an important content of medium and heavy plate production method. The materials of the protective layer are divided into metal and non-metal. The metal protective layer adopts electroplating, hot plating and electroless plating. Coating metals mainly include zinc, tin, copper, aluminum and chromium, among which zinc plating and tin plating are the most common. The cutting process of extra thick and medium plate has the advantages of high efficiency, large output, low cost and thick coating. Continuous plating method is often used for tin plating of thin, medium and heavy plates. Compared with hot-dip tin plating process, thin, medium and heavy plate processing tin plating process has the advantages of high cost and thin coating, but it has the advantages of uniform coating and good finish. The non-metallic protective layer is coated with one or two organic coatings (such as epoxy ester, polyester, acrylate, plasticizer sol, etc.) or cold-rolled medium and heavy plates, galvanized medium and heavy plates Plastic film on welded pipe, etc.

According to the arrangement of super thick and medium plate, there are four kinds of rolling mills: single stand rolling mill. The rolled piece is rolled in only one stand, a constant rolling mill. Several racks are lined up and driven by one or two motors. The rolled piece is rolled once or several times in turn in each stand, and the rolling mill is connected in series. Several stands are arranged in a row according to the rolling direction, and the rolled pieces are rolled in each stand in turn, but not in several stands at the same time, or although they are rolled in several stands at the same time, they do not form a continuous rolling relationship.

According to the principle of flame plate cutting, the high temperature formed by gas combustion is heated and melted by the cutting torch in a local range to achieve the purpose of cutting. However, it is not difficult to find the characteristics of carbon plates made from Q235 and other materials. The transition time from liquid to solid is usually very short, especially outside a certain temperature range, it will solidify rapidly. This will lead to serious slag inclusion in the cutting process of medium and heavy plate.

Firstly, from the formation position of slag hanging, the general flame cutting slag hanging can be divided into two types: upper edge slag hanging and lower edge slag hanging. The reasons for these two kinds of slag hanging are different, which will be described in the following categories.The slag hanging on the upper edge is mainly in the cutting part, especially in the lower half. The main reason for slag hanging on the upper edge is that the alloy content in the material is too high. Generally, flame cutting is mainly applicable to carbon plate made of Q235, carbon plate made of ordinary carbon and low alloy plate made of similar materials, such as Q345. However, if the alloy content is too high, slag hanging on the upper edge may occur.

The most common problem of flame cutting medium and heavy plate is slag hanging on the lower edge, which is mainly caused by continuous slag hanging on the lower edge of the cutting section. In order to solve this slagging problem, we only need to suit the remedy to the case and solve the causes of slagging one by one.
