In foreign countries are not distingu

3、ishedLeokingson 2007-03-22, 18:41The domestic 10mm and 12mm rebar are delivered in straight bars on the bar line, and the same specifications for the rebar on line are delivered in coils. Even more large foreign thread steel can also be shipped by coil.Could it be said that the standard for distingu

4、ishing rod, wire, and wire is not the diameter of the product. No matter what the diameter and shape are, it is called bar as long as it conforms to the standard of bar. It is called wire according to the standard of wire rod. There must be no product. The two kind of standard conforms to it. Ha ha,

5、 how to see all like rubbish.Hzwhy 2007-03-22, 20:25Our units of bar from 12mm55mm, wire rod from 5.522mm, I think should be straight or reel?. But my units will soon be on the market volume, diameter to 25mm, so I am also confusedZhohoy 2007-03-22, 22:00Study!Jeff_song 2007-03-23 00:09Before, accor

6、ding to the method of delivery, and now the process improved, the boundaries become blurred LiaoNmwzz 2007-03-23, 19:47Wire rod is coilBar is straight barThe specifications are crossedThere are no specific restrictionsOf course, more than 40mm is difficult to roll, but there areDesire train, 2007-03

7、-25, 11:34Or in terms of specifications and uses?Old Putin, 2007-03-25, 13:280.5 the following is the wire, and the other is the bar.Anbaochi 2007-03-26, 14:24This is not clear, I feel the dish called wire, straight bar called barSmallwolf 2007-03-26, 15:05There seems to be a distinction between the

8、 following 15MM called wire, the above is called bar. The domestic market volume comparison as early as possible is the Xingtai iron and steel, Daye special steel, recently at nangang. Upstairs that you want to roll on the market, I ask which units you are?Mrb63 2007-03-27, 12:41To distinguish betwe

9、en good specificationsPrincess 2007-03-27, 13:24The first floor of the answer is straightforward, the bar is straight bar, disk like wireZerozou 2007-03-27, 13:48I am learningRoll life, 2007-03-31 10:17Specifications can only be distinguishedKingema 2007-03-31, 11:03Wire rods should be able to be ro

10、lled up, of course, bars can not be rolled, and their use is not the same.Goaheadhq 2007-03-31, 15:41Well, I had a vague idea, and I think its still in terms of delivery.Buffalo 2007-03-31, 15:44I havent been sure yet. Some standards say so, I dont know what the difference is,Now I know something ab

11、out it. TKSFox and wolf 2007-03-31 22:16I have been confused, and it seems that everyone is not very clear ahAddie 2007-04-10, 15:554 floor of the predecessor is that factory ah, our company needs big size wire rod, ah, 14-32 of theAddie 2007-04-10, 16:00We did a good job of wire rod, but I havent b

12、een able to separate the above concepts. Does the wire contain a lot of things, and what should it be?Billzhao 2007-04-19, 17:21Not quiteFcc66011 2007-04-19, 17:29Bar is straight bar,Wire rod is shipped by plate,The diameter is not necessarily, sometimes they cross each other,Such as: 8, 10, 12 may

13、be bar, there may be wire rod,The most critical thing is that if the wire rod to produce, the speed, efficiency and capacity,The disadvantage is that the latter needs straightening.Lihaitao001 2007-04-30, 10:36It is customary to have wires that can be coiledKuangyunqing 2007-04-30, 10:48The use and

14、reproduction of records To borrow and reproduction persons should fill out the document during reproduction Records (see document control procedures AWEC-QP-001 approval by the), relevant responsible person during and reproduction.B030204159 2007-05-13, 14:20The main difference is that the delivery

15、status is differentJjj123 2007-05-13, 15:08Wire rod is mainly wire rod, 12mm diameter about, also have HRB330 hard line, outside light is smooth surfaceButler2007 2007-05-13, 18:58This problem is obscure, our company produces bar diameter from 12-90, 90-130 also have, but very fewI feel there is a c

16、oincidence between the twoHFC 2007-05-16, 17:17Previously we think there is a difference, but foreign countries already have a large round, and now a lot of domestic, only in accordance with the state of delivery.Qsingdong 2007-05-16, 19:13In China, according to the specifications are not the same,

17、small specifications for the line, large specifications for the barNmwzz 2007-05-16, 21:39Simply speaking, wire is wire rodBar is straight barBars and wires are not distinguished in diameterAccording to GB 702, 5.5mm-250mm has straight barsAccording to the national standard 14981 said 5.5mm-30mm is

18、a wire rodIn fact, now more than 30mm also has wire rod, that is, when spinning, do not spin machine, spit into disk circleInstead, the reels are made from reelsAsdf116 2007-05-16, 21:43Wire rods are usually rollsXuzggxu 2007-05-17, 12:59This is mainly in accordance with the provisions of their own

19、enterprises, we plant more than 20MM for bars, 20MM below for wireLhzsyly 2007-08-13, 16:22It is divided by the production process and equipment, and the specifications are crossed.Langzi_star 2007-08-13, 21:15Agree with the upstairs, should be in terms of production equipment and delivery to distin

20、guish,Learned a lotJinrt 2007-08-15, 15:45For non-ferrous metals, the general will be less than 5 mm diameter known as wire. Diameter 5 mm and rod diameter 5 mm or more, known as bar. In the non-ferrous processing manual, bars are not available below 5 mm in diameter.This division is not absolute.Si

21、mply speaking, wire is wire rod.Bar is straight bar.Caoshizhong 2007-08-15, 15:57It has to do with diameter and delivery status. The most critical thing to see is to produce according to that standard.Sailingytm 2007-08-15, 22:34Good thing, I see. Thank you.Lql2686129 2007-08-15, 23:00Bar is one of

22、the hot rolled strip steel. According to its cross-section shape, generally divided into round bar, Fang Gang, flat steel, six angle steel, octagonal steel, etc., there are periodic section steel, such as thread steel. In special cases, there is also a coil bar rather than a straight strip. The prod

23、uct specifications for bars are not strictly defined.Bars are widely used in machinery, automobiles, ships, construction and other industries. Some are directly used in concrete (such as rebar), and some can be processed by two times to make all kinds of shafts, gears, bolts, nuts, chains, springs a

24、nd so on.Wire rod is one of the smallest section sizes in hot rolled material. It is called wire rod because the rolling mill needs to coil the coil in hot state and deliver it.The definition of wire is not only recognized by the coil state, but also varies in diameter, section and shape with the pr

25、ogress of wire rod production technology, and different countries are different. The wire diameter of the provisions of China GB701-65 standard in 1965 5 to 1986 9 mm; Ministry of metallurgy in China issued by the YB (T) 17-86 standard, wire diameter range is 5.5 19 mm, 1988 to the national standard

26、 of high speed wire diameter range of the column with 5.5 22 mm. The relevant standards in the United States stipulates that the wire diameter ranges from 5.5 to 18.7 mm; the diameter of British wire rod is 5.38 to 25 millimeters; some countries extend the diameter of wire to 542 mm.The cross sectio

27、n of a smooth wire rod is circular in shape, but may be oval, square, square, hexagonal, eight sided, semicircular, or otherwise. For example, Germany DIN standard wire: round (size: 5 - 30 mm), square (size: 5 - 30 mm), hexagonal (size: 6 - 28 mm), semi circular specifications: (7 - 16 mm), flat st

28、rip: (size 8 x 1.8 7 mm).The wire rod also includes thread reinforced bar coil.The use of wire rod can be divided into two broad categories: one is the wire products directly used, mainly used in reinforced concrete reinforcement and welded structural parts. The other is the wire as raw materials, after p
