Anonymous users2024-02-10The raw material used in the adapter ring produced by Shandong Ed is 23mnnimocr54 alloy steel, which is one of the top adapter link materials in China, with high strength, high toughness, good cold bending ability and high breaking tensile force, etc., to ensure that the finished adapter can withstand the test of harsh environment.
23Mnnimocr54 is the first high-grade chain steel invented and used by the German company Thiele. Advanced chain is mainly used in the traction of underground transportation equipment, due to the harsh working environment, the best damage of steel directly threatens personal safety, so the chain must have high strength, high toughness, good cold bending performance, welding performance and fatigue resistance.
23MnNimocr54 steel is based on low carbon steel by adding alloying elements such as MN, NI, MO, CR, AL, etc., through the solution strengthening, grain boundary strengthening and second-phase particle strengthening of these elements, to improve the strength, plasticity and toughness of the steel, and at the same time improve the fatigue life of the chain by controlling the harmful elements in the steel, such as S, P.
23mnnimocr54 steel is widely used to make high-strength mining ring chains, which are matched with large mining machinery. The chain produced with 23mnnimocr54 steel has the characteristics of good wear resistance, high fatigue life, high strength, strong impact resistance and large load.
The product design, manufacturing and inspection standards of Shandong Ide are MT T99-1997 "Flat Connecting Links for Mining Ring Chains", MTT463-1995 "Inspection Specifications for Flat Connecting Links for Mining Circular Chains", and Q AiD01-2013 "Technical Specifications for Flat Connecting Links for Mining Rings".
Verified by a number of large state-owned coal mining groups and cooperative customers, the mining flat link produced by Shandong Ed can completely replace foreign imported products, and compared with it, it has the advantages of faster delivery, more comprehensive technical support, more timely after-sales service, and more favorable service.

Anonymous users2024-02-06The three-ring chain used for the lifting of the minecart is made of steel. The specific production is achieved by butt welding with high-quality welding equipment.
The mining three-ring chain is to make high-quality steel to be forged by six fires: the first fire of the mining three-ring chain: upsetting, drawing, flattening, pressing the initial type, forging stuffy end ring, large double-edged chopping ring, small double-edged chopping ring, point punching punching, punching residual material, and separating chain links; The second fire of the three-ring chain for mining:
Remove the remaining material in the middle and end rings, check the flash and deburr; The third fire: forging the half-ring at the end of the forging end, and removing the flashing burr from the inner and outer rings; Fourth, or talk about the fire time: forging the full end ring, going to the inner and outer flash, and checking and deburring; The Fifth Fire Pure Regiment Dan Times:
Forging the boring intermediate ring, going to the inner and outer flash, checking and deburring; The sixth fire: precision forging three rings, go to the burr edge in each ring, go to the outer flying edge of each ring, check and remove burrs; Compared with the welding process, the technical indicators are obviously better than the welding chain, and the continuous performance of the fiber structure of the whole forging three-ring chain is good, and the test results show that its impact, tensile and bending properties are higher than the standard requirements, and the product performance is safe and reliable. By the way, I will show you a strong brand in the field of domestic welding equipment:

Anonymous users2024-02-05The three-ring chain for mining is made of high-quality materials through die forging, and its middle ring is processed and forged by special welding technology, and then strictly inspected for surface flaw detection, so as to ensure the safety of the use of the product. Three-ring chain making is made from a single piece of material that has been forged six times. The three-ring chain of minecarts is suitable for transporting coal, gangue, materials and other types of minecarts and forestry timber transportation connection YMJT01.
Description of the manufacturing process of the three-ring chain for mining.
The manufacturing process specifications of the whole forging three-ring chain are not high, and the mining three-ring chain is to forge the steel such as the excellent cracked base six times
Minecart forging three-ring chain one fire: upsetting, drawing, flattening, pressing the initial type, forging stuffy end ring, large two chopping rings, small chopping rings, point punching punching, punching residual materials, separating chain links;
Minecart forging three-ring chain and two fires: remove the remaining material of the middle and end rings, check the flash and remove the burr;
The third fire of the three-ring chain of the minecart is forged: the half ring of the forging end is removed, and the flash burr of the inner and outer rings is removed;
The fourth fire of the three-ring chain forging of the minecart: forging the full end ring, removing the internal and external flash, and checking and deburring;
The fifth fire of the minecart forging three-ring chain: forging the middle ring, removing the internal and external flash, and checking and deburring;
The sixth fire of the minecart forging three-ring chain: precision forging of the three rings, go to the burrs in each ring of Qingyuan collapse, go to the outer flying edge of each ring, and check and remove the burr.
Production cost under the two subjects, there are direct materials, that is, the raw materials consumed in the current period, if the company has two levels of accounting, the end of the month accountant will send you the inventory table on the production line, and the worker consumption is summarized on the table, we use the data is the usual consumption of workers, in the actual work of the best enterprises can not remember the material consumption, usually the accountant with the production department of the material minus the inventory on the production line to squeeze out, the financial to get the consumption table with ** to get the production cost - direct materials. The cost of production is the consumption of raw materials, not the requisition. Some companies are too small or have no inventory online and no accountants, then the picking is the consumption of materials. >>>More
In fact, in practice, it should be like this, if the material is used for production, whether it is raw materials, or low-value consumables, or semi-finished products, turnover materials, etc., if it is determined to be used for that product when it is used, then it should be directly included in the production cost of that product, on the contrary, if it is not determined that it is used for that product, or it is used for several products together, then it cannot be included in the production cost of a single product, but should be included in the manufacturing cost, which is apportioned at the end of the month.
Furniture hot melt adhesive is used for wood, furniture laminated wood edge, PVC, melamine resin, etc. It is suitable for all kinds of linear edge banding machines, curve edge banding machines, soft forming edge banding machines, post-forming edge banding machines, etc. Packaging hot melt adhesive is used for automatic carton, carton packaging production, food packaging, flexible packaging, medical packaging, bottle and can labeling, etc. >>>More
I occasionally think that the most important thing to replenish blood is to replenish ferrous ions, and anemia is because the body does not have enough iron.
The main raw material of steel is iron ore.
and coke. Among them, iron ore is the most important raw material, and coke is an important reducer in the process of steel processing, which requires a large amount. Therefore, in the manufacturing process of steel, iron ore and coke are the most important raw materials, and they are also the most important factors affecting steel. >>>More
