  • When the temperature is running at the same temperature and the same heat is stored, the amount of iron dissolved is not the same. At around 500, the loss of iron increases sharply with the addition of temperature and insulation. It is lower or higher than 480~ 510c, and the loss of epitaxial iron is slower, and it is difficult to catch up with the duration. Therefore, everyone will call 480~ 510c the malignant melting zone.

  • The bonding and anchoring function between the cold rolled ribbed steel bar and concrete is outstanding. In reinforced concrete structure, the width of black iron wire processing crack is smaller than that of circular steel bar, even than that of hot rolled thread steel bar. Therefore, it is used in the component, which fundamentally eliminates the phenomenon of steel wire sliding and damage, and improves the load bearing ability and crack resistance ability of the component end.

  • Therefore, when the zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms are diffused with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with the iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with the zinc and sinks into the bottom of the hot galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • Hexagonal net in the landslide value is also quite high, many slopes through the baptism of the rain after this, there may be sediment flow and other disasters to the people’s property lead to a certain loss, with the existence of the hexagonal net, can fundamentally go up to solve the problem, sediment flow when it comes to it can implement effective protection, is the loss of many people to low. The hook mesh was installed on the hillside, still a nice view line. Under the irradiation of the sun, the metal material of the hexagonal net shines brightly, and its beautiful shape is combined, giving the mountain a kind of elegant feeling.
