阅读说明：本技术 一种镶铸包套钎焊柱钉排的高密度柱钉辊套及其制造方法 (High-density stud roller sleeve of brazed stud row of cast-in sheath and manufacturing method thereof ) 是由 黄齐文 黄闻欣 张新枝 于 2021-08-04 设计创作，主要内容包括：本发明公开一种镶铸包套钎焊柱钉排的高密度柱钉辊套,镶铸包套钎焊柱钉排的高密度柱钉辊套由包套钎焊柱钉排和镶铸固持包套钎焊柱钉排的辊套基体组成,是辊套表层均匀分布、镶铸有直线排列的、长度与辊套一致的或圆周排列的、外径与辊套一致的圆环形包套钎焊柱钉排,且包套钎焊柱钉排之间有不大于包套钎焊柱钉排厚度的间隙间距,所有柱钉在辊套圆柱周面上的所占面积总和与辊套辊面面积之比大于百分之五十,即柱钉密度大于50%。镶铸包套钎焊柱钉排的高密度柱钉辊套的制造方法如下：将包套钎焊柱钉排之间留有不大于包套钎焊柱钉排厚度的间隙间距、均匀分布固定在辊套铸造型腔的辊套外壁的铸型面上,浇注钢水后,钢水进入柱钉排之间的间隙,冷却凝固后,包套钎焊柱钉排被镶嵌铸造、固持在辊套表层。(The invention discloses a high-density stud roller sleeve of an embedded sheath brazing stud row, which consists of sheath brazing stud rows and a roller sleeve substrate for embedding and fixing the sheath brazing stud rows, wherein the roller sleeve surface layer is uniformly distributed and embedded with annular sheath brazing stud rows which are linearly arranged, have the same length as the roller sleeve or circumferentially arranged and the same outer diameter as the roller sleeve, gap intervals with the thickness not more than the thickness of the sheath brazing stud rows are arranged among the sheath brazing stud rows, the ratio of the sum of the occupied areas of all studs on the circumferential surface of the roller sleeve cylinder to the area of the roller sleeve roller surface is more than fifty percent, namely the stud density is more than 50 percent. The manufacturing method of the high-density stud roller sleeve of the embedded sheath brazing stud row comprises the following steps: and uniformly distributing and fixing the sheathed brazing column nail rows on the casting surface of the outer wall of the roller sleeve casting cavity, wherein the gap interval which is not more than the thickness of the sheathed brazing column nail rows is reserved between the sheathed brazing column nail rows, the molten steel enters the gaps between the column nail rows after the molten steel is poured, and after the molten steel is cooled and solidified, the sheathed brazing column nail rows are embedded, cast and fixedly held on the surface layer of the roller sleeve.)
