Abstract

The invention relates to the field of production machinery of ferrous metallurgy industry, and particularly discloses a rotary scraper and a manufacturing method thereof. The rotary scraper comprises a tool bar and a tool bit connected through a bolt. The rotary scraper is characterized by also comprising a jacket which is sleeved outside the tool bar and the tool bit. The method comprises the following steps of: manufacturing the tool bar; fixing the tool bit on the tool bar by using the bolt, and coating adhesive between the tool bit and the tool bar; sheathing the jacket outside the tool bit and the tool bar; drilling a hole on the bolt from the jacket at the part of deepening the bolt to the tool bar; and jacking a jackscrew into the hole, and vertically fixing the jackscrew on the bolt. According to the technical scheme provided by the invention, the service life of the scraper is prolonged, the integral toughness and the firmness of the scraper are enhanced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of production machinery in the iron and steel metallurgical industry, in particular to a rotary scraper for a sintering machine disc pelletizer and a manufacturing method thereof. Background technique [0002] In the iron and steel metallurgy industry, the process of producing sintered balls by the disc pelletizer requires extremely high wear resistance of the rotating scraper. At present, the rotary scraper usually consists of a connected blade head and blade shaft. Among them, the cutter head is usually made of hard alloy or ceramic wear-resistant material, and its wear resistance is insufficient, which reduces the service life of the cutter head, generally about three months. Moreover, the connecting bolts between the cutter head and the cutter bar are easy to loosen and fall off, which requires regular maintenance, which increases the labor intensity of the workers and reduces production efficiency; Rotary scrap...
