There are many specifications of cold drawn flat steel. The most basic specifications of flat steel are the length, width, height, diameter, half warp, nominal diameter, diameter and thickness of cold drawn flat steel. One of the main parameters of flat steel. The legal measurement unit for the length of cold drawn flat steel is meters, centimeters and millimeters.
Cold-drawn flat steel and flat steel basic theoretical weight calculation formula:
Cold-drawn flat steel (kg / m) W = 0.00785 × b × d
b = edge width mm
d = thick mm
Example: For flat steel with a side width of 40 mm and a thickness of 5 mm, find the net weight per meter. Net weight per meter = 0.00785 × 40 × 5 = 1.57 kg
The scope and size of cold drawn flat steel specifications is a reasonable countermeasure for saving raw materials, that is, the length, length, and width are not lower than a certain type of specification, or the length, length, and width are within the range of specifications. Supply, manufacturing enterprises can carry out production and delivery in accordance with this specification.
Where the product specifications of cold-drawn flat steel are within the standard range without fixed fixed specifications, it is called an uncertain ruler; and those cut into fixed fixed specifications according to the ordering regulations are called fixed lengths; If the fixed size is cut to the full magnification, it is called the double scale.
The length of the cold-drawn flat steel to be paid must be an integer multiple of the length specified by the buyer in the order contract when supplying the product in multiples. When the scale is delivered, only positive errors are allowed, and no negative bias is allowed. There are also differences between short and narrow gauges for cold drawn flat steel.
In which the length is lower than the standard uncertainty ruler length lower limit, but not less than the minimum allowable length is called a ruler. For example, the processing industry, machining and manufacturing of cold-drawn flat steel specifications require that 10% (calculated based on the number of single cymbals) of cold-drawn flat steel with a length of 2-4m each time is allowed. 4m is the lower limit of the uncertain ruler length, and the minimum allowable length is 2m. The total width is lower than the lower limit of the total width of the standard uncertain ruler, but not less than the steepest total allowable width. When delivering by narrow gauges, it is important to pay attention to the relevant narrow gauge proportions and steepest gauges.
The above are some related introductions about the specifications of cold drawn flat steel. I hope it will be helpful to everyone!
