Rectangular scraper,Its used for the Submerged Scraper Conveyor:

Origin: China

Brand: Qingdao Kechengyi

Introduction:

Rectangular scraper adopts channel steel and steel plate welding forming, article 65 Mn wear-resistant surfacing at both ends, quenching treatment, high strength, wear-resisting performance is good.

Features: scraper ontology for channel steel + web, channel steel + web form a closed rectangular section, channel steel flat stick welding wear-resisting plate up and down. The structure form of wear-resisting floor board the plane and conveying equipment contact, friction surface large (generally for 60-75 mm), greatly increases the wear resistance, scraper to the increase of time; For abrasion and plate without friction scraper ontology, the repeated repair technology is better, back to the chain across the head and slag shade, rectangular sweep scraper slag and slag basic vertical curtain working face, and slag shade can be more than 80% of the return slag into slag in the inlet.

Technical Characteristics:

The rectangular scraper has the same advantages with the triangular scraper, such as good rigidity, big bearing capacity, not easy to deform, and high return slag cleaning rate especially at the rear tension roller position. Meanwhile, it has improved the wear resistance performance and perfected the repeated repairing performance.

Forged Hinge Pin:

The hinge pin of the old type slag conveyor is fabricated by casting, which has deficiencies that may influence the safe operation, such as shrinking and loosening, air hole and sand hole, and easy to break. While the forged hinge pin is fabricated by the precision die forging forming technology, the structure is compact and strength is high, which has no the deficiencies of the casting hinge pin. The material of the forged hinge pin is CrMnTi alloy steel, taking carburizing and quenching to improve the wear resistance. In order to avoid the falling of pin shaft, the anti-rotating structure is used to connect the pin shaft and the hinge pin.
