Factory Quality Rebar-manufacture,factory,supplier from China

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.

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 ℃.

Ruiyu Company Held a Lecture on Rebar Anchor and Mining Anchor BoltsIn order to further promote the in-depth development of the activity of “Year of Improving the Grassroots Basis of Safety Production”, enhance the awareness of life safety of the whole staff, and create a strong safety propaganda atmosphere, Ruiyu held a speech contest with the theme of “Fear of Life, Safe Development, Starting from Me” on the morning of Nov. 26th. On the morning of Nov. 26, Ruiyu Company held a speech contest with the theme of “Respect Life, Safe Development, Starting from Me”.

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.

Current application of mining anchorThe original anchor retaining wall construction is completed and in use for a period of time, because in the planning of the unfavorable elements do not  part, the construction process of the construction of the quality of the construction is not controlled or not in accordance with the construction process of construction, in the process of application because of man-made or natural factors, etc.

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.

Comparison of left-handed anchors with other anchorsLeft-handed anchor is a kind of engineering structure used to support tunnels and rock bodies. Left-handed anchors are easy to make and transport, simple to construct, and can greatly improve the quality and safety of the project. This technology has been widely used in tunnel construction and coal mine support and other fields.Second, the structure of left-handed anchorLeft-hand anchor consists of steel bar, bundle rib and self-locking nut.

Shandong Ruiyu Carries Out Winter Fire DrillIn order to further strengthen the fire safety management and improve the fire safety awareness of the workers, Ruiyu Company organized 12 representatives from each department and workshop on November 18, 2024 to conduct a fire accident emergency treatment drill in the open space on the south side of A workshop.

Principle analysis of the collapse reduction effect of left-handed anchorsIf the unstable rock layer of the vault is regarded as the combined beam (plate) supported by the side wall, because the anchor hanging on the stable surrounding rock can be regarded as the fulcrum, the installation of left-handed anchor without longitudinal ribs is equivalent to adding the fulcrum, reducing the support span, and then reducing the bending stress and deflection of the support to maintain the stability of the support and the rock, so that the rock is not easy to deform and damage.

2024 Coal Industry Benchmarking Work Conference Held in JiningThe 2024 Coal Industry Benchmarking Work Conference was held in Jining City, Shandong Province, which was organized by China Coal Industry Association, co-organized by Shandong Coal Industry Association, and undertaken by Jining Energy Bureau and Jining Energy Development Group.
