| 铣削型钢纤维的母材是初扎钢锭,钢块,通过刀具铣削加工成型,由于受到母材自身抗拉强度的限制,所制成的钢纤维的抗拉强度通常为600Mpa.据有关资料研究显示,通常情况下,上述四种类型钢纤维抗拉强度在同等材质条件下（如碳钢）,以钢丝冷拉切断型为最好,以下依次是钢板剪切型,钢锭铣削型和钢水熔抽型.因此,工程实用中故需根据钢纤维类型,通过调整钢纤维的掺量来达到设计要求,或者采用锰钢作为母材来弥补强度的不足. The base material of milling profiled steel fibers is initial ingot and steel block. It is formed by milling with cutting tools. Due to the limitation of the tensile strength of the base material, the tensile strength of the steel fibers is usually 600 Mpa. According to the relevant data, the tensile strength of the four types of steel fibers mentioned above is usually the best under the same material conditions (such as carbon steel), and the cold-drawn and cut-off type of steel wire is the best one in the following order. xuanzhuang.89ix.comchengde.71ix.cngaonianji.07858.net shepiguan.89ix.combianyaqipd.37ix.com.cn laliji.07858.netIt is steel plate shear type, ingot milling type and molten steel pumping type. Therefore, in engineering practice, it is necessary to adjust the amount of steel fiber to meet the design requirements, or use manganese steel as base material to make up for the strength deficiency. 该品生产工艺没有超出税则第72章商品的范围，应根据其外观特征归入热轧相应品目,如带状波浪钢纤维,根据归类总规则一,可考虑归入品目72.11.由于其主要用途就是钢纤维混凝土的基本添加料,若贸然归入税号73.26是值得商榷的 The production process of this product does not exceed the scope of the goods in Chapter 72 of the Tax Rules. It should be classified into the corresponding hot-rolled products according to their appearance characteristics, such as banded corrugated steel fibers. According to the first general rule of classification, it can be considered to be classified into item 72.11. Because its main use is the basic additive of steel fiber concrete, it is worth discussing if it should be classified as Tax No. 73.26 rashly. |
