Abstract

The fluid blowing roller of the present invention includes a rotating unit having a through hole formed on an outer circumferential surface; a disk unit fastened to an outer circumferential surface ofthe rotating unit and having an outlet for discharging fluid flowing in from the through hole to the outside; a blocking unit disposed inside the rotating unit to block the flow of a fluid of a portion of the through hole.

Description

technical field [0001] The present invention relates to a fluid jetting roll capable of conveying steel plates or plates without causing wear. Background technique [0002] Following the trend of strengthening safety regulations worldwide, automobile companies are expanding the use of high-strength steel in order to reduce fuel consumption and ensure crash stability. For this reason, steel companies use a method of increasing the strength of steel by using a phase transformation structure in order to manufacture high-strength steel. This is because it is difficult to cope with this tendency only by existing mechanisms such as solid solution strengthening and precipitation strengthening. [0003] In order to increase the strength of steel utilizing a transformation structure, it is necessary to add a large amount of alloy elements such as Si, Mn, and Cr. However, Si, Mn, etc. are oxidizing elements, which combine with oxygen during the hot rolling process and continuous ann...
