Rolling Margin of Steel |What is rolling margin of steel?|How to calculate Rolling Margin of Steel?

Today we will be discussing a very important topic Rolling Margin of Reinforcement Steel As soon as they heard these words many people became excited What is Rolling Margin And where is this used Or how do you calculate it You can also use this in Billing or Reconciliation So what is Rolling Margin Rolling Margin is a difference that is Actual Weig The actual weight of the steel received is as the steel we receive And after receiving its lengthwise We take the actual weight And the Standard Weight is Standard Weight means unit whatever the Running Weight is Running Weight per kg The unit standard running weight per kg is steel His weight is 120 kg The difference between the two is 10 kg We call this Rolling Margin Now in today's video See details about Rolling Margin Rolling Margin of Reinforcement Steel Learn the Rolling Margin of Reinforcement Steel First of all we need to What is rolling it is very important to know Rolling is a type of manufacturing process that results in sheets and cross sections Like Large Length Beam I-Beam Rail Boards it is about Reinforcement Bar This is their extended version In Metal The forming process also speaks in which there is a separate term for Metal Work The metal work pieces that are in separate compartments are Roles are cooperated and it is Their lung capacity increases the process is this The cross-sectional area decreases then their length increases The production rate is very high during the process The surface finish is also good and the grain structure is good It is also very suitable for metal forming It also includes larch trees for the lake Cross-sectional work is followed It is used again but it has a high setup cost The roller machine's cover or the other one its alternative We can also use the process How do they classify rolling It has different types of rolling such as Thread and Gear rolling is done in which followed by Shape rolling Then Ring Rolling then Tube Piercing Then there is Skews Rolling then there is Transverse Rolling We are all doing this right now Right now its roots are still shallow There is no need to be attached to it What is the main concern the production of steel It has quality it has durability we need to look at it What is a rolling margin Rolling margin is a percentage of deviation the sectional weight of reinforcement steel Alaw Visa is I-Score in the I-Score Steel's difference Actual Weig And the difference in Theoretical Weight His I-Score percentage is 75 He has a leave of absence We are the rolling margin So this is the rolling margin the steel that is A tie that is Pass or fail in that by passing And the roller to him It is manufactured Any record diameter required it is this one They manufacture it As I said that If you want to speak The difference that arises in this is The one who is the ala'abillah deviation We call it the rolling margin It has a fourth deviation We refer to it for him It contains a tab in the window in the middle Nominal cross section area Who are the ones who are different types of Diameter is steel As 4 mm 5 mm 6 mm 8 mm 10 mm 12 mm 16 mm 20 mm 25mm28 mm32 mm 36 mm 40 mm The purpose of doing this is to ensure that the translation is accurate and meets the required standards This is a steel casting The process of Reverse is a unique one It includes diameter As time goes by The diameter with Or else shape changes occur Then his result instead of the exam The diameter of the left steel is also Changes happen and these are both in the process Difference is better than loss It makes a difference in the weight of steel Now it tells the size of the diameter It's as if he's very small Then from his mou A rolling margin becomes negative In the initial stage and in this case If you ask after you it is more or less close to It approaches theoretical weight or else it is negative And now if the size of the diameter is They increase then It contains a table the tolerances of normal mass It is close to 6.2 and 7.2 2 serial number nominal size tolerances up to and including 10 in Batch wise is given plus or minus 7 individual sample is given minus 8 And an individual sample for coils the one that remains from the coils plus or minus 8 is given up to over 10 and including 16 mm as specified plus or minus 5 for the batch Individual sample minus 6 and individual sample for coils plus or minus 6 is given over 16 mm The batch is plus or minus 3 the individual sample is minus 4 and the individual sample for coils is plus or minus 4 For individual samples plus tolerance is not specified plus tolerance is not specified and single sample taken for a batch as defined in 3.1 What I have mentioned here shall not be considered as an individual sample For coil batch Tolerance is not specified Here there is no calculation for rolling margin so how does it work So rolling margin is the percentage of deviation in sectional weight of reinforcement steel as per IS Reinforcement steel is extruded from a mold for a particular size For example if it is 8 mm in diameter When this mold remains the sectional weight of 8 mm steel extrusio Then they take the remaining from the mold exactly as per It is standard weighing 8 mm 0.395 kg per mm from whic It comes less Then when mold gets a little bigger After using Jaira Then after that after a certain period Any quantity of production we take one And then they measure it later Now same if it's 8 mm Then it is extruded into the same mold into the same mold its Later the weight that comes is 0.400 kg per meter instead of 0.395 kg as per IS This is more mass per meter length same length is required this is that is more mass per meter length meter per length Now this deviation They have different diameters Whatever is its percentage is mentioned Now how do ruling managers calculate there is a formula for it He calculates it along with this A sample report is available Then it will appear Then they will appear first eoretical weight 1.5750 actual weight 1.517 difference-0.0583 percentage of difference-3.698 this is 16 mm percentage This is the second time it has a 16 mm 1.5 specified unit weight actual length 1.002 theoretical weight 1.583 actual weight 1.527 difference 0.0562 3.547 percent difference this is the second time 16 mm in size It also has a specified unit weight of 1.58 actual length 1 m theoretical weight 1.58 actual weight 1.523 difference 0.0570 percentage of difference 3.608 This is a 27 mm bar with a specified unit weight of 2.469 and an actual length of 0.998 eoretical weight 2.464 actual weight 2.418 difference between both 0.0461 -1.869 percentage of difference It is the second time its specified unit weight is 2.469 actual length 0.997 theoretical weight 2.462 actual weight 2.421 Both have a difference of 0.0406 percentage of difference 1.649 Third time 20 specified unit weight-2.469 theoretical weight-0.996 eoretical weight -2.459 actual weight-2.42 difference-0.0391 -1.591 percentage difference This is how they calculate the percentage based on this calculation We will see now steel reconstruction in the rolling margin How is it used first we will see The standard weight of steel is 1.58 kg per meter and the length of steel received His weight has come 1.63 kg on the scale Then if 1 divided by 1 steel came then 1 divided by 1.63 divided by 1.63 is equal to 1 61349.693 meters but what is the actual length of steel according to standard weight 1 divided by 1 58 is equal to 63291.139 meters the weight loss in it such as differences exist 1.63-1.58 divided by 1.58 then what is the total 3.16% this is the rolling margin of reinforcement steel as we have seen the rods What is reinforcement steel in rolling margin How to remove it How do they do it What is its importance And with it The Isabes of the Ice Code What is it What percentage is it So friends how did you like this video Please leave a comment If you're watching my channel for the first time Then definitely subscribe And the side bell
