Production Flow of Q235, A36, SS400 Hot Rolled Steel Flats 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:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
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:The distinction between flat steel and steel strip
Flat bar is strip, mostly 30*3, 40*4, 50*5 and so on. Strip: Blue (sometimes called black) is a chemical treatment, the surface to form a dense oxide film, corrosion and decoration;
Q:What is the difference between 60X6 and 50X4 flat steel in grounding?
The contact resistance varies with the return current.
Q:Where can I buy ground level bending machine?
Galvanized flat steel and galvanized steel (or steel) for welding, reliable connection, should be in addition to the contact regions on both sides of the weld, should also direct the flat curved (or rectangular) and steel (or steel) and steel pipe welding, when welding on the steel pipe wrapped around the welding length 2 times less than the width of flat steel.
Q:How many steel tubes can be used instead of 60 * 10 flat steel?
Stainless steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded pipe (seamed pipe) two kinds of NO.320 stainless steel plate fine grinding NO.2D and NO.2B material, grinding of stainless steel 301 - good ductility with 320# abrasives abrasive belt, used for molding products.
Q:Why is it better to use round steel than that of flat steel in lightning protection?
Presumably, it's a discussion, not an answer.At the same length and with the same cross section,(1) the contact area between flat steel and earth is slightly larger.(2) flat steel is easier to bend than round steel, so it is more convenient to construct.(3) flat steel is easier to connect with bolt by connecting bolt.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
Water is to protect the wall foundation using cement mortar width not less than 600 of a circle along the walls of the cement ground, if the main part of the project before the electrical engineering, auxiliary grounding length less than in bulk water, auxiliary grounding, ditching to destroy the water, so that the design requirements of 1 meters water is conducive to the construction of welding, may be more than one meter in order to facilitate their work.
Q:Galvanized steel flat welding occurs after the material itself crack.
Reheat cracking: when welding in the heat affected zone near the fusion County Office is heated to 1200 DEG C, the heat affected zone of grain boundary of vanadium and molybdenum and titanium carbide in austenite when welding; postweld heat treatment of re heating, the heating temperature in the range of 500 degrees to 700 degrees Celsius in the welding, there is a big the welding residual stress in the joints, stress exceeds the plastic heat affected zone near the fusion line of the metal, will produce crack;
Q:Does the cable trench need grounding?
According to the design requirements of excavation and masonry, the groove side wall welding force angle, steel frame and required to ground, covered with the cover of the underground channel, that is, cable ditch. Its purpose is to lay underground tunnels for cables.
