Production Flow of High Quality Round Bar
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.
- Q:How to distinguish cold formed section steel and hot rolled section steel?
- Cold-formed steel is one of many varieties of steel in the strip width, under normal temperature conditions after the roll, a group of vertical deformation gradually, to meet the requirements of the use of shape and size, then determine the size of the corresponding shear length. This product is cold-formed steel. Of course, it is also possible to obtain cold-formed steel by stamping, bending or drawing. But the roll bending forming method is suitable for industrial production in large quantities. Its product quality, processing cost and production efficiency are incomparable with other methods, and it is the main production process of cold-formed steel. If the equipment is equipped with welding equipment (such as high-frequency welding, argon arc welding, etc.), it can also produce cold rolled steel with closed section.
- Q:What kind of steel is used in steel columns?
- The steel sheet pile has various forms, and the sides of the steel sheet and the joint groove are different in shape. The second plate, after the first one is in place, takes the front sheet of the sheet pile and the side notch is used as the driving point. As a result, a plurality of sheet piles may form relatively complete sheet pile walls along the coast (or bank of the river). In addition, a group of steel sheet piles can be used for temporary retaining protection when the foundation pit is excavated or excavated.
- Q:What does "BH" mean?
- In accordance with the different smelting quality of steel, steel is divided into ordinary steel and high quality steel. According to the current catalogue of metal products, ordinary steel can be divided into large section steel, medium section steel and small section steel. The section steel can be divided into I-beam, channel steel, angle steel, round steel and so on according to its sectional shape.
- Q:Does the profile include H?
- Profiles include section H steelThe online quote H steel and profiles in the angle of groove separate quotation, mainly because H steel has great use compared with the other, and the demand is relatively more, but in some cases, and H type steel I-beam can also substitute for each other.
- Q:Elastic modulus of section steel
- The elastic modulus of steel is 2.1 * 10^7N/cm L.
- Q:What are the common types of profiled steel?
- Complex section steel has: I-beam, channel steel, steel, elevator rail, steel sheet pile, and various kinds of agricultural machinery, machinery manufacturing and construction of special-shaped steel.Section steel according to production methods are: hot-rolled steel, cold-formed steel, welding, H steel, etc.
- Q:What is special steel?
- Agricultural steelAgricultural steel is the main means of agricultural production and agricultural private or semi private steel, mainly are: Farm steel: Farm steel is commonly used steel for rural primary system of small tools and general civil tools. Main is a small section of round steel, flat steel and other varieties of composite steel composite steel billet, billet and hoe sickle knife blank, used in the manufacture of sickle, hoes and other small tools and other tools (such as knife, etc.). This kind of composite steel consists of two same components of the carbon steel hot rolled, low carbon steel is outside the body, soft and tough body steel seismic, good adhesion, easy sandwiching a layer of grinding. Leaf blade steel containing carbon, manganese, hard and wear-resistant, polished production tool edge is very sharp.
- Q:What does "M" mean?
- The former refers 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:Can the section steel butt joint in the end?
- If welding, it is mainly worried that the welding is not strong and the welding stress is too large. The wall thickness of the section steel is thin, and the butt welding itself is the most unreliable. So, in the joint lining board, fillet welded. Attention is paid to reducing stress in the process.
