Production Flow of Hot Rolled Round Bar

We use advanced equipments like Electric Arc Furnace, Ladle Furnace and Vacuum Degasser to produce our products.

The common processes are preheated forging quenching, dual refinement solution process, cooling quenching and isothermal quenching. We use heat treatment for dual refinement solution process. The main measures process is high temperature solution and refinement cycle. High temperature solution can improve the carbide morphology and particle size. The aim is to make the loop refinement ultrafine austenite grains.

Preheated Round Bar

Q:Square steel and C steel which is better?
Then use the square. Beautiful C steel, general color steel is not used. See you square high-rise, is firmly with the 100 by 100.
Q:Building height is 5m, the main dry hanging stone square spacing value should be how much better?
Really not assured, spend some money to let people count, but as long as there is no special structure or shape, then you do not have to spend the wrong money.
Q:The steel structure material can do
Yes, if you are easy to do, you can
Q:How to ensure the steel paint off paint
The first thing to do (clean dust, oil removal, in addition to soluble salts), and then choose to kill or polish, then under suitable conditions (humidity is less than 85%, the substrate temperature is higher than the dew point of at least 3 degrees Celsius) and construction paint. Well done, the paint won't fall off.
Q:The difference between galvanized square and galvanized steel
The galvanized pipe with square tubes is galvanized steel strip processing, forming, anti-corrosion time, there is no hot galvanizing time, hot galvanized is processedThe black tube. Galvanized in galvanized square tube factory. After 1000 degrees of high temperature, the general wall thickness is relatively thin, can not do hot-dip galvanizing.
Q:What is the use of square steel keel or welding steel canopy
What material is most suitable for the construction of the canopySelect the canopy material, is the most important part of the awning construction, suitable materials, not only save money, and effort, but also worry. The awning material is usually divided into: "sunshine in canopy, canvas canopy, laminated glass awning, canopy tile".
Q:How to combine the paint and galvanized steel
You can spray paint directly. General zinc plating, basically do not need to paint, if galvanized can not resist the corrosive environment, you can use non galvanized just now, and then use the way to strengthen the anti-corrosion (primer + epoxy resin, or asphalt).
Q:Twist steel (twisting steel) there is no standard?
Because the steel plate for standard parts, CAD drawing without draw, only need to mark the type and size of the bearing flat steel lattice steel plate and the direction of the steel grid plate, the specific use of what types of bar, can be specified by the user, if the platform is too large, can be discharged from the layout of steel grid plate manufacturers, general row layout is free.
Q:4*4 steel welding frame tank do strong?
If you want to be firm, you can use the three and four sections. The middle slot can be clamped on the edge of the fish tank, and the tripod should be four. It's so convenient and strong!
Q:The difference between cold and hot galvanized steel hollow where
Hot rolling process is: the ingot directly into square tube, and then galvanized, also known as seamless pipe.Usually than cold-rolled steel hot-rolled square steel prices high.
