Barter is the present and the future of international trade, especially for people who is starting in the import export business. Barter and more: Triangular operations.
Scraper as coal mine coal transport equipment, the daily workload is still very large, especially the larger annual output of coal mines. As for the beam of the scraper, the heavy load will also make its wear faster. When the beam of the scraper wears badly, it will be timely updated and replaced.
The function of the beam of scraper conveyor is equivalent to that of E-type and U-type bolts, which mainly fix the scraper through single-head bolts to form the chain of scraper. In the middle trough, the chain scraper chain is driven by the sprocket shaft group to do circular movement to complete the coal transport.
Most scraper conveyor beam material is 40Cr. There are two main production techniques for the beam of the scraper conveyer: forging and casting. Casting is the casting of molten metal liquid poured into the mold, cooling and solidifying to obtain the desired shape and performance of the parts. Casting is a common manufacturing method in mechanical manufacturing. But the products produced by casting process may have cracks, pores, slag holes, sand holes, shrinkage holes and so on. Forging can avoid the loose phenomenon in the casting process and optimize the metal structure. Forged parts have better strength and toughness. Therefore, the mechanical properties of forgings are better than those of castings of the same material.
As the transmission parts of the scraper conveyor, the cross beam is connected with bolts, which has large load, severe working conditions and easy wear and tear.
Do you know the 15GL3-2 beam of the scraper conveyer after reading it? Double of henan machinery equipment co., LTD., production of major host manufacturers supporting the scraper conveyer beams, elaborate threaded hole shape, size, and form a complete set of forging connecting bolts, threaded hole and the bolt clearance reduction, reduced beam string, the connection between the beam and scraper and firm, to prolong the period of beams, reduce consumption of scraper conveyor accessories for the general customers.
