High Quality Stainless Steel Square Washers-manufacture,factory,supplier from China

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 ℃.

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.

Shandong Ruiyu Mining Material Processing Co., Ltd. has 39 employees. It is a designated manufacturer of new mining material products, since the establishment of the factory, the support materials on the continuous introduction of advanced technology. While guaranteeing the production quality, we have improved the safety production efficiency.In 2017, we obtained the certificate of safety mark for mining products, and in 2018, we passed the iso 9001 quality management system certification.

In order to effectively improve the level of job skills of the company's employees and vigorously promote the smooth development of job training activities, the company carried out a job skills competition on November 28 in the anchoring agent workshop.The skills competition is divided into twisting tube, anchoring agent filling, cement filling three major projects, take the way of practical operation, the requirements of the specified time to complete the largest number of players and quality qualified for the first place in this project competition.

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.

The anchoring force test method of left-handed longitudinal ribless anchorsLeft-handed anchor without longitudinal rib has high strength, reasonable structure, large pre-tensioning force, can automatically adjust the direction of force, increase the binding force on the surrounding rock, and can realize mechanized rapid installation.Advantages of left-handed anchor:High strength anchor, reasonable structure, large preload, can automatically adjust the direction of force, increase the binding force on the surrounding rock, can realize the mechanization of rapid installation.

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

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.

33mm Split Tube Seam Anchor AdvantagesAs a kind of rock support equipment used in underground mining and civil engineering projects, 33 mm pipe seam anchor shows many advantages in engineering practice. First of all, its high load-bearing capacity is one of the main features of this anchor.

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.
