4, The calculation method of stainless steel
Calculation method for theoretical weight of stainless steel plate:
Plate weight = specific gravity × thickness (mm) × width (m) × length (m) (mm is the unit of millimeters, m is the unit of meters)
In the field of engineering machinery, due to the precision of the dimensions, the world uses millimeters as 1000 mm = 1 m and 1 mm = 100 filaments.
The weight obtained by this formula is kilogram (KG), which is accurate to two decimal places. Because the price of stainless steel is high, the transaction volume is large, and the number after the decimal point is very important, so the money should be accurate to two decimal places. Bit.
Calculation formula for stainless steel:
Stainless steel tube: (outer diameter - wall thickness) × wall thickness × 0.02491 = Kg / m
Stainless steel plate; thickness * (width × length) × specific gravity == Kg / square centimeter
Round bar: (diameter × diameter) 0.00623 = Kg / M
Volume Price: Flat Price * Theoretical Thickness / Actual Thickness - Opening Fee
Flat plate price: volume price * actual thickness / theoretical thickness + opening fee
Theoretical calculation formula:
Coil: Weight, weight, thickness (actual thickness) × theoretical thickness = weight
Coil open plate: length, width × width × thickness × density = weight
Medium plate: length × width × theoretical thickness × density = weight
Roll length: actual weight ÷ width ÷ thickness (parameter thickness) ÷ density = roll length
Actual thickness of the roll: trimming roll = roll weight ÷ width ÷ roll length ÷ density
Burr roll = (volume weight - edge weight) ÷ width ÷ roll length density
Flat price: flat price = (volume weight * market base price - edge wire amount + opening fee) / total tablet weight
Example 1: Calculating the cost per ton of raw edge rolls
Such as, 4 * 1535 * C, reference thickness 3.5mm, volume of 9876 kg volume, the price of the flat plate 18,500 yuan / ton, Kaiping fee 80 yuan / ton, calculate the cost?
Solution: raw edge volume cost price = market base price * actual thickness / standard thickness + opening fee + edge wire cost
Example 2: Calculating the cost per ton of a trimmed roll
Such as, 6 * 1500 * C, reference thickness 5.6, volume of 8566 kg volume, the market price of 18700 yuan / ton on the day, Kaiping fee 60 yuan / ton, calculate the cost per ton?
Solution: cutting edge cost price = market base price * actual thickness / standard thickness + opening fee =18700*5.6/6+60=17513.33
Example 3: Calculating the actual thickness
Such as, 304/NO1, 10*1500*C, the volume weighing 8682 kg, the specific gravity is 7.93, now open, 10*1500*8.195, three; 10*1500*6200, one piece; 10*1500* 7.85, two pieces; 10*1500*6000, five pieces; 10*1500*2050 tail plate piece, now calculate the actual thickness?
Solution: actual thickness = total weight / width / total length / specific gravity = 8682 / 1.5 / 78.54 / 7.93 = 9.29
