We all know that at the same height, the light channel steel is narrower than the general channel steel, the waist is thin, and the weight is light. Large channel steel, channel steel is medium channel steel. Imported channel steel indicates the standard of practice and related specifications. The import and export order of channel steel is generally based on the specifications required in the application after confirming the corresponding carbon steel (or low alloy steel) steel number.
In addition to the specification number, the channel steel has no specific composition and function series. The delivery length of the channel steel is divided into two types: fixed length and double scale, and the rule tolerance value is in the corresponding specification. The length selection of domestic channel steel is divided into 5 -12m, 5 -19m and 6 -19m according to the specification number. The length of the imported channel is generally 6-15 m.
Analysis of the optimization and modification of the shearing process: The 400mm unit in a steel plant is a profile unit mainly producing medium angle steel and channel steel, with an annual output value of 650,000 tons. The specification of channel steel products is 638~1208, and the output value accounts for the total output value. 25 percent. The segmentation of the product channel is carried out using a 400t cold shear.
The shear quality of channel steel has a great influence on the subsequent process, especially the welding quality. If there are shortcomings such as collapse shoulder, burr, tear, and skew at the shear fracture, there will be a large gap when the channel is butt joint, which will affect the welding. Quality, especially strength targets, then create a greater safety hazard.
The above is the relevant specification questions about imported channel steel that YanXinSenYu has summarized for you. If you have any comments or suggestions, you can consult our online customer service, we will serve you wholeheartedly!
