Compression roller, steel surface treatment device and surface treatment production line for steel

The utility model provides a compression roller, a steel surface treatment device and a surface treatment production line for steel. The steel surface treatment device comprises a compression roller.The surface treatment production line comprises a steel surface treatment device. The pressing roller comprises a roller body and embossing protrusions. The embossing protrusions are arranged on the outer surface of the roller body, the embossing protrusions are made of alloy, and the hardness of the embossing protrusions ranges from 85 HS to 100 HS. The compression roller can be used for rollingsteel, so that an oxide layer on the surface of the steel is broken, the crushing rate of the oxide layer on the surface of the steel can be effectively improved, the production and manufacturing costis saved, and the production and manufacturing efficiency of the steel is improved. 本实用新型提供了一种压辊和钢材表面处理装置以及用于钢材的表面处理生产线。钢材表面处理装置包括压辊。表面处理生产线包括钢材表面处理装置。压辊包括辊本体和压纹突起。压纹突起设置在辊本体的外表面，压纹突起的材质为合金，且压纹突起的硬度为85HS至100HS。根据本实用新型的压辊，可用于辊压
