Flush the lines to remove all loose scale , dirt and other foreign matter that can damage or clog the valve 冲洗管线，清除可能损坏或堵塞阀门的所有疏松的氧化皮、污垢和其它外来物质。
Sand and rusts removing of largesized cast iron , cast steel , steel surface treatment of oxidized workpieces 0大型铸件、铸钢件、钢结构件、大型锻件、热处理件的清砂、除锈去除氧化皮表面清理等。
Sand and removing of large - sized cast steel , steel structures , large - sized forging and surface of oxidized workpieces 大型铸铁、铸钢件、钢结构件、大型锻件、热处理件的清砂、除锈去除氧化皮表面清理等。
Angular when new , this grit rapidly rounds off in use and is particularly suites for decaling applications 此种磨料新制成时，是尖棱状的，使用过程中棱角很快就被磨圆，特别适合于钢材表面去氧化皮预处理作业。
The treatment of pulsating electric current at room temperature can break up oxidation surface of grains and improve the conditions of reaction 提出了冷态下的脉冲电流处理可破碎粉粒表面的氧化皮，改善坯料的反应条件。
Sand and rusts removing of large - sized cast iron , cast steel , steel structures , large - sized forging and surface freatment of oxidized workpieces 大型铸铁、铸钢件，钢结构件、大型锻件，热处理件的清砂、除锈去除氧化皮表面清理等。
Blast cleaning of all except tightly adhering residues of mill scale , rust and coatings , exposing numerous evenly distributed flecks of underlying metal 喷砂除去所有附着的氧化皮、锈迹和漆膜，除了牢固附着的。露出大多数的有锈斑点的钢板。
Sg / gp steel grit ： angular when new , this grit rapidly rounds off in use and is particularly suited to removing sand of casting and scaling oxide Gp钢砂：此种磨料新制成时，是尖棱状的，使用过程中棱角很快就被磨圆，特别适合于落砂及去除氧化皮作业。
For steel members received these treatments , rolled scale , rusted attachments are erased into punctual blotch , and sliver gray metal is exposed instead 这样处理后的构件表面轧制氧化皮、锈和附着物残留在钢材表面的痕迹已是点状的轻微污痕，构件表面露出银灰色的金属光泽。
Although harder than gp steel grit , gl also loses its sharp edges during shotblasting and is particularly suited to descaling and surface preparation applications 尽管此类钢砂的硬度比gp钢砂要高一些，但在喷砂过程中仍会失去棱角，特别适合于钢材表面驱除氧化皮预处理作业。
