Product Description:

Uses
1,Fixed footbolt is also called short footbolt, it is poured together with the foundation and used to fix the equipment without strong vibration and shock.
2,Activity foot bolt also known as long foot bolt, is a kind of removable foot bolt, used to fix the work of strong vibration and shock of heavy machinery and equipment.
3,Expansion anchor anchor bolt is often used to fix the static simple equipment or auxiliary equipment. Expansion anchor anchor bolt installation should meet the following requirements: the distance from the bolt centre to the edge of the foundation is not less than 7 times the diameter of the expansion anchor anchor bolt; installation of expansion anchor anchor bolt foundation strength shall not be less than 10MPa; drilling holes shall not be cracked, and attention should be paid to preventing the collision of drilling bit with the reinforcement bars in the foundation and the embedded pipe; the diameter and depth of drilling holes should be matched with the expansion anchor anchor bolt.
4,Bonding anchor bolt is a kind of anchor bolt commonly used in recent years, and its method and requirements are the same

Applications

There are two main ways to judge the hardness of steel, which are Brinell hardness in HB and Rockwell hardness. Firstly, from the Brinell hardness, will be a hardness higher than the measured steel ball to the steel above, and apply a force F, then the ball will be in the measured steel will leave a dent, measured, the area of M, then Rockwell Brinell hardness will be F/M. Next Rockwell hardness is also convenient to explain the only difference between the latter and the former Rockwell hardness measurements is the force to force to divide by the depth of the small ball plunged into the.

Steel can be improved by mixing it with alloys, for example by adding carbon, known as carbon steel, which increases its hardness and rigidity but decreases its toughness and plasticity. By adding chromium, the hardness and rigidity of steel can be increased with less effect on its toughness. By adding titanium, the hardness and toughness of steel is increased.

The properties of steel can vary after different types of processing, with a focus on quenching and tempering, two of the earliest forms of steel processing that I learnt about as a child, both of which I learnt about through the game Ride and Slash. Firstly, quenching is the process of heating steel to over 723 degrees and then soaking it in water for a rapid cool down to increase the hardness and decrease the malleability of the steel. Tempering means heating the steel to over 723 degrees and then cooling it slowly to increase its strength and toughness at the same time.
