How to calculate the weight of a tin rod or a circle
The current GOST 860−75 provides for the production of a volumetric tin assortment of the following types and sizes:
- Round bars with diameters of 8… 15 mm;
- Tin rods of pyramidal section;
- Chushkovy metal (foundry tin).
The length of each tin rod should be within 400 ± 20 mm. The supply of tin rods is produced in packs weighing 10… 15 kg. At the request of the customer, it is possible to change the length of the rod, as well as its packing in any kind of packing.
To the number of bulk rolled tin also include anodic bars, which have a rectangular cross section. GOST 860−75 provides the following sections of tin anodes: 10x70, 5x70, 20x40, 30x55 at a length of up to 2 meters, 10x100 at a length of up to 1 meter, 10x200 at a length of up to 1 meter.
The mass of bars of a circular cross-section can be determined from the known dependence:
V = 3,14r 2 h, where r is the radius of the wire, and h is the length of the section of the tin rod or circle. Then the desired characteristic will be determined from relation
M = Vρ, where ρ is the density of tin.
For the most common brands of tin, the density indicators correspond to the following data:
- For tin of high chemical purity — 7290 kg / m 3 ;
- For basic solders based on tin — 8850 kg / m 3 ;
- For other tin grades — 7300 kg / m 3 .
The company Electrovek-steel offers to purchase at economically favorable prices of the manufacturer bars and a circle of tin in accordance with GOST 860−75. The supplier guarantees the timely delivery of the metal to any point specified by the customer.
The mass of the rods from the tin of non-circular cross-section is determined as follows:
The cross-sectional area of the pyramid is found from the dependence
F — (a + b) h / 2, where a is the length of the larger side of the pyramid, b is the length of the smaller side of the pyramid, and h is the height of the bar in the cross section.
According to GOST 860−75, the sizes of tin pigs in the plan are:
- A = 75 mm;
- B = 55 mm;
- H = 35 mm;
- The length of the piglet is l = 295 ± 5 mm.
According to the given data, taking into account the known density of tin ρ = 7300 kg / m 3, it is possible to establish the mass of one rod or pig. The following formulas are used: V = Fl; M = Vρ. Similarly, we can calculate the mass of tin anodes.
Buy at an economical price of tin in bars or pigs offers the company Elektrovek-steel. The supplier guarantees the operative transportation of the products to any point set by the consumer.
