Production Flow of Mild Steel Flat Bar

The Mild steel flat bar is made through three processes:

1.Feeding the material: Feeding the row material (the steel plate) to Slitting Line.

2.Slitting:The steel plate would be slitted into expected width by lengthways cutter.

3. Leveled and cutting: The plat bar would be ground into level by the grinder and then cut into required length

Q:The steel, steel and flat steel, round steel bar and what is the difference?
There is not much difference between round bar and steel bar, but the diameter range should be different. Can you hold it with hand?Inside the details of the difference, you can go to the tool book to see.
Q:Friction coefficient of steel pipe and flat steel on roller table!
Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (Xing Gang). the formerRefers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:How many years can hot dip galvanized flat steel be used?
Coastal areas usually refer to a region within a mile of the sea. The ocean atmosphere can spread deeper inland, especially on islands. The prevailing winds come from the ocean, and the climate is bad. If the wind is mixed with ocean fog, especially due to evaporation and accumulation of salt deposits, coupled with less rain and less frequent rain erosion, coastal conditions will be even more unfavourable. If there is any industrial pollution, there is more corrosive. Hot galvanized flat steel in such circumstances, usually 20 years or so.
Q:What is the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:Does the cable trench need grounding?
Cable trench grounding practices: ground pile using hot galvanized steel angle (50X5X2500), every 20 meters to hit a root. The pile top is 0.6 meters away from the ground, and the ground wire is made of galvanized steel flat bar (40X4). Cable grounding wire and cable groove on both sides of the main frame by welding, every 20 meters will ground wire leads and grounding pile welding, while the grounding cable trench on both sides of the ditch bottom connection, grounding wire used for 10 hot dip galvanized steel. All grounding devices need to be welded firmly at the joint, and the welding place is treated with asphalt.
Q:What's the meaning of ground flat steel -60*8 hot dip galvanizing?
- (minus) on behalf of 60 represents is flat; flat cross section length is 60mm, 8 represents the thickness of 8mm steel;
Q:What is the rolling range of the micro cold rolled flat steel production line?
Ferrous metals are alloys of iron and iron. Such as steel, pig iron, iron alloy, cast iron and so on. Steel and pig iron are based on iron, carbon as the main additive elements of the alloy, collectively referred to as iron carbon alloy.Pig iron is the product of smelting iron ore into a blast furnace. It is mainly used for making steel and casting.Put the casting pig iron smelting in cupola, to obtain iron (liquid), the liquid cast iron cast into casting, the cast iron is cast iron.
Q:The grounding electrode 50 angle steel and the ground wire 50, the flat steel lap welding, according to the specification 169 needs the flat steel to be late 90 degrees, bends close to the angle steel side, the overlap width is 4 times (200mm)?
GB50169-2006 in the 3.4.2 stipulates that the grounding body (line) shall be welded by lap welding, and its lap length shall comply with the following requirements:1. flat steel is 2 times its width (and welded with at least 3 edges);2. round steel is 6 times its diameter;3. round steel and flat steel connection, its length is round steel diameter of 6 times;
Q:Do lightning protection, lead out of the galvanized round steel, flat steel needs to be inspected?
No, when purchasing hot galvanized round steel and flat steel, please offer the factory certificate and inspection certificate.
Q:What are the standards for the use of galvanized steel angles and flat steel for grounding?
The top of the grounding body from the ground 0.5 ~ 0.8m, in order to avoid thawing soil, soil resistivity or steel angle as the root number of the ground around the body and decide, generally not less than two, each spacing is 3 ~ 5m
