产品概述

硅钢也叫电工钢,是一种铁硅合金,其中硅元素具有磁性。硅元素的添加改善了钢材的软磁性并增加了电阻率,主要用作电机、变压器、电器以及电工仪表中的磁性材料。硅钢一般是低碳钢,碳含量则不高于0.08%,硅含量在0.5%-4.5%之间。硅钢可进一步分为取向硅钢和无取向硅钢,其中取向硅钢还可细分为常规取向硅钢(RGO)和高导磁率取向硅钢(HGO)。硅钢以其高磁导率和低铁损率而闻名,这使其在电力行业用途中备受青睐,例如大小型电机、继电器、螺线管、电器电机、风力涡轮机、变压器铁芯、新能源电动车、发电机设备等。


产品特性

  • 1

    由于硅钢的高磁导率,低矫顽力和高电阻系数等特性,因而有较低的磁滞损耗和涡流损耗


  • 2

    为了制造电器时满足冲剪加工的需要,还要求有一定的塑性。为了提高磁感性能,降低磁滞损耗,要求其有害杂质含量越低越好,并要求板型平整,表面质量好


  • 3

    热轧硅钢的生产工艺目前在中国已经被淘汰,目前生产提供的都是冷轧硅钢。中联物产供应的硅钢的铁损性能远远超出各国的标准上的铁损要求
