鑄鐵平臺的整修及行為偏差介紹

鑄鐵平臺（鑄鐵平板）工作表面應(yīng)無砂孔、氣孔、裂紋、夾渣及縮松等鑄造缺陷。各種鑄造表面應(yīng)清除型砂、且表面平整，涂漆牢固。各棱邊應(yīng)修鈍，在精度等級低于“00”級的平板工作面上，對于直徑小于15mm的砂孔允許用相同的材料堵塞。其硬度應(yīng)低于周圍材料的硬度。在工作面上堵塞的部位應(yīng)不多于四處，其相互之間的距離應(yīng)不小于80mm。

Cast iron platforms (also known as cast iron plates) and bed castings as a large casting must be heat treated to improve their performance and improve the intrinsic quality of cast iron plates. Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing methods, heat treatment generally does not change the shape of the workpiece and the overall chemical composition, but by changing the microstructure inside the workpiece or changing the chemical composition of the surface of the workpiece. Improve the performance of the workpiece. It is characterized by improved internal quality of work.
Cast iron platform (cast iron plate) working surface should be free of casting defects such as sand holes, pores, cracks, slag inclusions and shrinkage. All kinds of casting surfaces should be cleaned of sand, and the surface is flat and the paint is firm. Each edge should be blunt, and on a flat work surface with an accuracy level lower than “00”, sand holes of less than 15 mm in diameter are allowed to be blocked with the same material. Its hardness should be lower than the hardness of the surrounding material. There should be no more than four places on the working surface, and the distance between them should be no less than 80mm.
