答:冷硬铸铁轧辊是利用铁水自身的过冷度和铸模表面的激冷作用获得的一种铸铁轧辊,它的碳含量一般为2.9%~3.2%,硅含量为0.25%~0.8%,冷硬铸铁轧辊的材料属于亚共晶铸铁,按合金含量和种类不同分为普通冷硬铸铁与合金冷硬铸铁轧辊。
A: The chilled cast iron roll is a type of cast iron roll which utilizes the undercooling of the molten iron and the chilling effect of the mold surface. The carbon content is generally 2.9% -3.2%, and the silicon content is 0.25% -0.8% The material of cast iron roll belongs to hypoeutectic cast iron, which is divided into common chilled cast iron and alloy chilled cast iron roll according to the content and type of alloy.
