CRC

Steel material specifications and usage
 
Background:
With the rise of industry in Indonesia especially in the automotive industry and accompanied by the development of the state of development in Indonesia, particularly steel material needs increase. Where the presence of steel into something material or material that can not be separated to support such developments. Business opportunities in the field to become a major steel in the country indonesia.dan dlihat from year to year increase. And until the steel producers to meet the unmet needs of domistik ultimately in particular industries using steel material steel material brought from abroad (imports). Material is to come from: Japan, Korea, Taiwan, china, thailand, and vietnam.
  Various kinds of steel products:
1. Include Steel Rolling Steel Rolling Hot and cold rolling
2. steel Forging
3. steel extrusi
Here I will explain the kinds of steel-making process:
1. steel Rolling
Steel produced by the rolling process, and carried out the heat and cold. The material is a material that can be produced in the form of coil and wire. Material yag form of coil there are 2 types, to hot rolling in the call HRC (Hot Rolling Mill) and cold rolling called CRC (Cold Rolling Mill) and To Wire called SWRM and SWCH
2. steel Forging
Dihasil a steel forging process (forging)
3. steel extrusi
Steel that produced by the extrusi.

Cara Menghitung Berat Baja



In the steel business in the field we have to know the density of iron as it is very important to be able to calculate the weight of the material we sell and also can estimate the material that we will need.
By knowing the specific gravity of iron we can know the weight of material per piece or a total weight of how many pieces of material. And also to determine the price perberat or per piece.
Here I'll show you how to calculate weight of iron to iron a different dimension, as follows:


1    . Steel Plate/Sheet

 Rumus : 
 Thickness( mm ) X Width( mm ) X Length (mm ) X Density = Weight ( KG )
 Density                                 : 7,85 ( Gr/dcm3 )
                                             : 7,85  ( g/(100)^3 mm                   
 Example 
 Plates have a size                 : thickness: 3,0 mm, Width : 1219 mm, Length : 2438 mm,
                                             How    Much weight?  
 Weight Plates                       : 3,0 mm x 1219 mm x 2438 mm x 7,85/1000.000 =  69,988 Kg




2.       . Steel Round Bar/Solid

 Rumus :
 Weight Round Bar ( Kg )     : 3,14 x Radius x Radius x Length  x 7,85/1000.000

Examples:
Round Bar Diameter             :  100 mm,  Length : 6000 mm, How Much Weight?
Weight   Round Bar              : 3,14 x 50 x 50 x 6000 x 7,85/1000.000
                                            : 370 Kg

Alternative                           : Diameter x Diameter x 0,006165 x length
                                           : 100 x100 x 0,006165 x 6000
                                           : 370 Kg



3.       .Steel Pipe

 Rumus:
 Weight Pipe ( Kg )              : Diameter-Thickness x Thicknessx 0,02466 x Length

Example :
Pipe Out side Diameter        : 100 mm, Thickness : 1,2 mm, Length : 6000 mm , How Much weight ?

Weight Pipe Per Pieces        : 100 mm -1,2 mm- 1,2 mm x 0,02466 x 6000/1000
( Kg )                                  : 14,4 Kg




Thank you, good luck
