- Q:What does "billet" mean?
- Steelmaking and continuous casting of steel products are mainly used for steel rolling, such as round bar, wire rod, sheet metal and so on
- Q:Billet market trend
- 3, Tangshan billet inventory declineIt is understood that in April, the Tangshan region began to decline in the stock of major steel warehouse, as of April 28th, Tangshan billet inventory at about 1 million 250 thousand tons, a drop of about half higher than the high point. But some vendors have revealed that some of the resources are being transferred from the warehouse to the traders. In fact, inventories are much larger than statistics, and the inventory of 1 million 250 thousand tons of steel is about 2.5 times that of the same period of last year.In addition, network analyst China industry insight believes the macroeconomic situation, the weakening of steel and steel industry more negative news of the credit crisis will be unfavorable to the billet market outlook. But considering the steel production has been at a loss, the billet has a certain resilience; and before the May Day holiday billet prices fell rapidly, it is possible to pull up the opportunity to play after the manufacturers in a certain way.
- Q:What are the common defects in billet? What's the cause?
- Five, X ray inspection, porosity, ultrasonic testing:One, 5, magnetic particle inspection, the back of the dent; 6, overheating and over burning: 1, penetrant inspection;Four. 2. The size of the weld does not meet the requirements and slag inclusion; 3 high-energy X-ray inspection, lamellar tearing and R ray flaw detection; 2;Five;Two: 1, arc crater;Methods for inspection of weld defects;
- Q:What is the approximate cost of billet to cold rolling?
- The cost of billet to cold rolling is about 1000Galvanized to color coated sheet costs vary greatly, generally around 300, a high of 500
- Q:Billet heating furnace billet temperature reached, steel will be adhesion
- As soon as the melting point is reached, the part melts before sticking. But heating will swell a lot, you need to leave enough space.
- Q:Continuous casting billet has slag inclusion and air hole
- In the production process of steel castings, the appearance of quality defects is unavoidable. It is essential to take reasonable measures to avoid the inclusion of slag in the cast steel. It is necessary to understand the reason why the porosity of the cast steel is caused by slag inclusion so that the quality of the cast steel can be improved.In order to solve the pinhole of slag phenomenon, the first thing to do is to understand the cause of steel casting porosity slag phenomenon, and take corresponding measures according to the original material,
- Q:Difference between billet, slab and billet
- Steel billet is a product made by steel-making furnace by casting. The billet can be divided into two kinds from the manufacturing process, mould blank and continuous casting billet. At present, the casting process has been basically eliminated. The classification is mainly divided into two kinds: slab: large cross section, high ratio, mainly used for rolling plate. Billet: cross section width, height equal, or difference is not big, mainly used for rolling steel, wire. Use billet is steel, through processing can be used as mechanical parts, forgings, processing all kinds of steel, steel, Q345B, channel steel, wire is the role of billet. Billet is used for the production of semi-finished steel products, generally can not be used directly for society. Billet and steel are strictly divided into standard, and can not be determined by the final product of the enterprise, but should be carried out according to the uniform standard of the whole society. Usually, billet and steel is relatively easy to distinguish, but for some billets, with the same specification and the same purpose (such as rolling and steel tube), whether for other industries by use, whether through steel processing process, whether after finishing mill processing to distinguish. Continuous cast steel square and rectangular billets are mainly made of plain carbon steel, low carbon and low silicon cold rolled material, high quality carbon structural steel, low alloy high strength steel, special steel and so on.
- Q:What does the billet of the steel plant refer to?And steel what is the difference?
- The main deformation of reinforced by ribs, binding capacity larger and concrete, so it can better withstand external force. Steel is widely used in all kinds of building structure, especially for large, heavy, light and thin wall structure of high-rise building.
- Q:Who knows the diamond is?Who knows the diamond is carbon? Is it C60?
- It is also called the diamond diamond, crystal, it is not the molecules themselves, so the formula does not apply to.C said it is only by this kind of carbon elements. While C60 is footballene is another matter, the 60 is because it is a molecular crystal, each molecule consists of 60 carbon.
- Q:What does the billet of the steel plant refer to?
- The steel billet is the continuous casting machine by smelting steel plant casting into the blank, in the middle of products before entering the rolling process, the section size will be decided by rolling steel. When rolling the long material, the square billet is poured, the rolled plate is cast, the rolling pipe is cast into round billet, and the rolled narrow strip steel is poured into the rectangular billet, etc..
