Guide roller of papermaking machine

Abstract

The invention discloses a guide roller of a papermaking machine. The guide roller comprises a roller body, wherein a hollow part is arranged in the roller body; a plurality of bulges are uniformly arranged on the inner wall surfaces at the two ends of the hollow parts; antioxidant coatings are coated on the surfaces of the bulgesare coated withantioxidant coatings; each bulge comprises is prepared from the following raw material components in parts by weight: 60-80 parts of titanium steel, 15-35 parts of ferric pyrophosphate, 5-15 parts of expanded vermiculite, 0.1-2 parts of cobalt, 0.1-2.5 parts of antimony and 0.5-2 parts of yttrium. The guide roller is high in hardness, is resistant to oxidization, is resistant to corrosion, is high in processing quality, is simple in structure, is delicate in design, is convenient to replace, is low in cost, and is long in service life.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a papermaking machine guide roller. Background technique [0002] In recent years, the paper machine has been widely used in the foundry industry due to the advantages of cost-saving sand cores, good air permeability of sand cores, smooth surface of castings with low gas generation, high precision, and good mechanical properties. The use of core shooters can not only save a lot of Auxiliary equipment and tools for core making can also reduce labor intensity, create conditions for mechanization and automation of the core making process, and have a good application prospect; however, the currently used rollers are generally used for rolling. The processed water products are uneven, which limits the overall performance of the core shooter during processing; in view of the above defects in the prior art, it is necessary to further improve the existing device to make it ...
