Steel strip

Hot-rolled steel strip belongs to the flat-rolled category and is a universal metal profile widely used in industry and construction. Long-rolled strip products are used as a blank for the production of metal products for various purposes (including hardware products), and as an independent material in the production of construction, installation and finishing works. Classification, size range, basic geometric parameters and maximum deviations for hot-rolled steel strip are established by assortment in accordance with GOST 103-2006, marking, packaging and logistics are carried out in accordance with GOST 7566-94.

Assortment according to GOST 103-2006, accuracy class and weight per linear meter

According to GOST 103-2006 (instead of GOST 103-76, which is inactive since June 13, 2009), hot-rolled steel strip is divided into categories:

1. According to rolling accuracy

: B - increased accuracy, B - normal, separately in width and thickness. Designation for strip with increased thickness rolling accuracy: BT1, BT2, BT3, designation for normal thickness rolling accuracy: VT1, VT2, VT3.

The width rolling accuracy is indicated in the same way: BSh1, BSh2, BSh3 (increased accuracy) and VSh1, VSh2, VSh3 (normal accuracy).

2. As intended

:

• general purpose band (GP);
• strip used for stamping nuts (GShG - hot stamping, KhGSh - cold stamping).

3. By sickle class:

• AC - crescent shape is no more than 0.2% of the length of the strip.
• BS - permissible sickling within the limits of up to 0.4%.
• BC - sickling up to 0.5%.

4. Length

: strip of measured length (MD), unmeasured (ND), multiple of measured length (CD), in rolls (RD).

5. According to maximum deviations in length

(only for strips of measured and multiple measured lengths): BD - group of increased accuracy and VD - group of normal accuracy.

GOST 103-2006 establishes the following size range of long rolled strip: strip width (b) from 10 to 200 mm, thickness (a) from 4 to 80 mm.

Hot-rolled steel bars GOST 103-2006, dimensions and weight of 1 linear meter

Weight of 1 meter strip

can be calculated independently using the formula:

M linear meter, kg=0.00785×a×b, where a and b are standard values ​​for the width and thickness of the tape in millimeters.

Hot rolled strip range

The production of hot-rolled strip products with a thickness of 4-80 mm and a width of 10-200 mm is regulated by GOST 103-2006.

The theoretical calculation of the mass of this metal product is carried out using the average specific gravity for steel - 7850 kg/m3.

Example notation

When designating a steel strip, the following characteristics are taken into account:

• above the fractional line, thickness and width, rolling accuracy, purpose, crescent class, current assortment GOST 103-2006;
• under the fractional line is the steel grade, GOST, which regulates the specifications.

For example: hot-rolled steel strip 4 mm thick, 40 mm wide, standard rolling accuracy in width, thickness and length with a crescent tolerance of up to 0.2% from ST3kp according to OST14-2-208-87.

Materials used in the production of steel strip

Depending on the material and manufacturing method, the range and specifications for rolled strip, in addition to GOST 103-2006, are regulated by the following regulatory documents:

• GOST 1435-99 . Relevant for strip, rods, ingots, sheets and other metal products manufactured by various methods - forging, hot rolling, rolling and sizing. The material for the manufacture of this product is unalloyed steel.
• GOST 5050-2000 . Defines technical conditions for rolled strip made from alloy tool steels.
• GOST 19265-73 . Regulates technical conditions for metal products in the production of which high-speed steel was used.
• GOST 4405-75 . Determines the range of forged and hot-rolled strip products made from tool steels.
• GOST 7419-90 . Regulates the assortment of hot-rolled metal used for the manufacture of springs.

According to rolling accuracy, strip products are produced:

• class B – increased accuracy;
• class B - normal accuracy.

Determination of the mass of a batch of steel strip

To develop estimate documentation and purchase rolled strips, it is necessary to calculate the required amount of rolled metal in kilograms. To do this, you can use an online calculator or calculate using the formula M = ρ*a*b*l , in which:

M – product mass, kg;

ρ – density (specific gravity of steel strip), kg/m3, the average value for steel is 7850 kg/m3;

a and b – cross-sectional sides, m;

l is the length of the rolled strip.

Another calculation option is to use a table that indicates the mass of 1 m of rolled steel of a certain section. When this value is multiplied by the total footage, the mass of the batch is obtained.

Features of steel strip

So, in comparison with other types of rolled metal, a strip is a flat and thin steel strip. The hardness of which is divided into especially high - PO; high - PV and normal - PN.

Also, during manufacturing, there are specific requirements for the source material; it must withstand significant loads. There is also a requirement for this metal to be sickle-shaped.

It can be high - AC; increased - BS and normal - BC.

In addition, the service life of hot-rolled steel strip is long, it amounts to tens of years. Therefore, this particular type of rolled metal is in great demand. The material undergoes anti-corrosion treatment, which also significantly increases service life.
