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: What does "M" mean?
- M section steel: sectional shape steel like M.
- 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: 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: Elastic modulus of section steel
- Generally speaking, the elastic body exerts an external function, and the elasticity experiences the change of the shape (called strain). The general definition of the elastic modulus is that the stress is divided by the strain. When the material is in the elastic deformation stage, its stress and strain should be changed into a positive proportion (that is to say, according to Hooke's law), and the coefficient of proportionality is called the elastic modulus.
- Q: What kind of steel is used in steel columns?
- Section I and H of steel reinforced piles belong to the common section shapes in steel reinforced concrete piles. I and H type steel piles can be used in horizontal load and vertical load bearing. The steel pile has stronger penetration ability in many kinds of strata, moreover, its disturbance to stratum is slight, it is a kind of partly squeezed soil pile. If the distance between the driving pile and the center is smaller, the H steel pile can be used to replace other piles to prevent the ground fault caused by piling operation, such as lateral extrusion, uplift and so on.
- 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: Can the section steel butt joint in the end?
- Bolt connection also requires lining plate, pay attention to bolt size, quantity and spacing. To calculate whether thin-walled steel itself will be crushing, the solution is solder paste board, and bolt holes. The principle is that the strength of the butt joint is not weaker than that of other parts, and there is no greater stress.
- 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: How to distinguish cold formed section steel and hot rolled section steel?
- The difference between cold-formed steel and welded steel tubes is that welded steel pipes are mainly used for conveying fluids, such as gas and tap water. Petroleum, liquefied petroleum gas, steam, etc. The steel tube is subjected to a certain amount of pressure, while the cold-formed steel is used to make the structure. Under the action of external force, the cold-formed steel is required for the section, shape, size and mechanical properties of the section steel.
