In coal mine roadway, the anchor rock bolt is one of the most important materials in a supporting role, Anyang Longteng heat treatment material co., LTD., a new heat treatment process, greatly improving the strength and impact toughness of ordinary steel anchor, to solve the ordinary rock bolt hit problem
Anyang Longteng annual production of high-strength and high-performance heat-treated steel 150,000 tons, has passed EN 10204 Type 3.1 Inspection Certificate for anchor bolt, stud bolt, structural tie rod products.
The main products are: high-strength stud bolts, wind energy anchor bolts, blade bolts, high-strength hexagonal head bolts, embedded sleeves and other high-strength fasteners.
If a metal material factory has passed the ISO 9001 certificate issued by an EU-authorized certification body, and the metal material meets the European material specifications, the factory can issue an EN10204-3.1 material certificate to its customers.
Most wind generator mainly used in wind farms adopt anchor cage foundation, main function of anchor plate is to connect the bolt and concrete structure
In the design and construction of mining roof bolts support, support forms and parameters are selected based on experience or engineering analogy, so there are some problems, such as difficult roadway maintenance, low coal production rate and tight mining replacement.
Here is a sample of small steel mill for rock anchor bolt production. Steel Mill adopts all rolling system, the air and gas – double heat furnace, use steel billet as raw material, with alternate arrangement of 6 roughing mills, and finishing mill group
