Q3: What’s the Processes Flow of Flat Steel Bars?

A3:The 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:Are there any differences between flat iron and flat steel?
There are many kinds of iron ore, magnetite, hematite, corresponding to the main components of the ore should all know, or in a similar "write reaction equation" with the topic of carbon monoxide reduction of magnetite occurs, will be at a loss what to do. Next should mainly reflect the principle on iron smelting to understand the reducing agent for iron reduction, must pay attention to the test of the formulation of the phenomenon - "red brown powder into black" (which is often the examination content). From here, the principle of blast furnace ironmaking is approximately the same. For some knowledge in actual production, we should understand the basic structure of the blast furnace five furnace two, three import and export ", and each part of the chemical reaction, the slag formation reaction, the need to pay attention to is: the composition of blast furnace gas is a mixture of gases such as carbon monoxide, carbon dioxide and nitrogen, after purification to it is a gas discharge, good fuel.
Q:Lightning protection grounding, what is called three surface welding?
The grounding position of the grounding body shall not be less than 3m; when the ground is embedded in the garbage or ash, it should be changed and compacted.The grounding body (line) shall be connected by welding, the welding seam should be full and adequate mechanical strength, no slag, undercut, crack, weld, welding defects such as pores, knocking the net after a drug paper, brush asphalt anticorrosive processing.
Q:How is three grade steel connected to ground flat steel?
HRB400 can be directly welded by hand arc welding with Q235 flat steel into electrical circuit. (I have done two sets of tensile tests last year, qualified).
Q:The technological process of flat steel
The spring flat steel is made by converter smelting process. Compared with the prior art, the utility model has the following advantages and positive effects:1. refining flat steel with converter, mainly using hot metal as raw material, less harmful elements in molten iron, the quality of flat steel produced is guaranteed.2., because of the high rate of finished products and less power consumption, the cost per ton is lower than that of the electric furnace.3. the molten steel is directly cast into billets, omitting the cogging process and reducing the cost.4., continuous casting billet, fixed rate is high, can ensure flat steel fixed rate, to meet the needs of users.
Q:Is medium plate steel flat?
No, the production process is different.Flat steel can replace a small part of the plate (steel), flat steel is generally fixed rolling, length can be fixed, 1 meters, 30 meters can also do.
Q:The difference between galvanized flat steel 40*4 and galvanized flat steel 80*8 is the difference on the material list!
Here, your galvanized flat steel refers to the basic matrix is carbon content less than 0.18% carbon steel (Q235), after galvanizing (general hot plating), play the role of surface oxidation resistance, corrosion resistance. Generally used in the power sector, what you mention is the difference in size.
Q:How can copper clad steel ground electrode and galvanized flat steel be welded?
If you want it to work well, use heat release welding, and if you take into account the cost budget, there are connectors, connectors that are just mechanical connections
Q:What is the difference between steel band and steel ring? The steel strip is flat steel and the steel ring is made of steel. Am I right?
Steel rolls are also called steel belts. There is no difference between them. They are not flat steel
Q:Where is the use of flat steel in electrical use?
Other equipment or cable bracket parts connected with bolts, flat width of less than 25mm with a 8mm bolt or two 6mm bolts. The width is less than 40mm by using two 10mm bolts, width 40-50mm uses two 12mm bolts, all bolts are galvanized, double single elastic gasket. In fact, all electrical components should be hot-dip galvanized (except welded steel pipe).
Q:How to grounding lightning protection grounding?
The main rib of the column is larger than 16MM in diameter and is connected with the galvanized steel bar which is connected with the ground.
