Abstract

The invention discloses a wear-resistant filter plate special for slag and a preparation process of the wear-resistant filter plate. The preparation process specifically comprises the following stepsthat firstly, a filter plate substrate is manufactured; secondly, material mixing operation is carried out; thirdly, the surface of the substrate obtained in the first step is covered with the mixtureobtained in the second step, the substrate is preheated, the preheating time duration is controlled to be 10-20 min, the substrate is fed into a rotary furnace to be subjected to sintering operation,the sintering time duration is controlled to be 1-3 h, and finally the substrate is taken out and cooled to normal temperature; fourthly, after the filter plate obtained in the above steps is cleaned, polished and deburred, the filter plate is manufactured into a porous structure, and the thickness of the filter plate ranges from 30 mm to 50 mm; and fifthly, the manufactured and formed filter plate is dipped in a graphene coating, so that a graphene coating layer is formed on the surface of the filter plate, the dipping time duration is controlled to be 20-30 min, and then the filter plate istaken out. Tensile strength, compression resistance and wear resistance of the filter plate are enhanced, aging of the filter plate can be avoided, and the service life of the filter plate is prolonged.

Description

technical field [0001] The invention relates to the technical field of slag filtration, in particular to a special wear-resistant filter plate for slag and a preparation process thereof. Background technique [0002] Slag is a by-product of the blast furnace ironmaking process. In industrial production, slag plays an important role, especially in some large-scale factories; it is made of slag and processed into slag cement, slag powder, slag powder, and slag silicic acid. Salt cement, slag cotton, blast furnace slag, granulated blast furnace slag powder, copper slag, slag vertical mill, saving energy consumption; [0003] Therefore, when the slag is used for secondary use, the impurities in the slag must be filtered first. The slag filter plates currently used have low compression resistance and wear resistance, which greatly shortens their service life, and these filter plates cannot Effectively filter dust.
