Perforated Steel Sheet Metal-manufacture,factory,supplier from China

Alloy Steel Industry Market Analysis to 2025China's alloy steel steel production overall shows a steady rise, which is mainly due to the rapid development of China's automobile and other fields. Data shows that China's alloy steel steel production in 2019 was 47.0243 million tons, and by 2023 it will be close to 61 million tons.

Common sense maintenance of right-handed equal-strength threaded anchorsTo introduce you to the maintenance of right-handed equal-strength threaded anchors: Mining anchors have irreplaceable advantages compared with traditional metal anchors.

Borehole diameter of anchor rods is related to soil conditionsWhat is the typical drilling diameter of anchor rods?Anchor bar is a common foundation reinforcement material used in construction projects. It is made by pre-burying steel bars in the soil, and then pre-stressing and mechanically drilling them, so that the steel bars are tightly bonded with the soil, thus the strength of the soil and foundation can be improved.

What is the anchor beam system of anchor rods?At present, in the production mines of various companies in China, some of the mining depth has reached more than 500-1000 meters, and the ground stress, surrounding rock force and deformation are complicated and diverse, a single anchor support can no longer meet the requirements of support for the broken roof plate, composite roof plate, and the roadway with high roof plate pressure, and the anchor beam system, which is composed of the anchor rods and the W-beam steel belt, can effectively control the roof plate, and it can be used in the support

Recently, our company has newly developed a new type of support material, and the effect is obvious after use."Now there is a new type of support material, so that coal mines use lighter and more durable support, both to save production costs, but also to reduce the labor intensity of workers, the cost savings can be used for more innovative investment." A mine digging work area technician Li Ming said.It is reported that the new support material is an ultra-high strength support network.

Factors affecting the quality of anchor tray determinations(1) Environmental temperature change, due to thermal expansion, the balance of the unequal arm and other reasons, will make the balance of the zero point and the equilibrium point of change, the value of the occasional deviation can be up to a number of times the balance of the sensibility. Thus, the balance room should be a constant temperature, first-class, second-class standard balance and first and second-class laboratory balance should be 20 ℃ ± 2 ℃ under the conditions of work, the accuracy of a little lower to reach 20 ℃ ± 5 ℃.

Prestressed anchor flexible support technology and its applicationDeep foundation pit support technology has always been a popular and difficult point of concern in the academic and engineering circles.

What are the elements that affect the decrease of anchoring force of mining anchor rods?With the development of mine support technology, anchors and anchors are used in conjunction with each other. However, in the detailed underground use process, due to the quality of the anchoring material itself, irrational design, improper operation process, underground geological conditions and many other factors, the anchoring force will be greatly reduced. This will lead to deformation of the roadway, and even topping and roadway collapse accidents.

Anchor rods are a type of support equipment commonly used in civil engineering and mining projects to enhance the stability and safety of underground structures. Here are some key points about the development trend of anchor rods:Advances in material technology: with the continuous development of material technology, the application of new materials is changing the performance and reliability of anchor rods.
