什么是铸造轧辊，吊车轨哪家好，铸造轧辊主要有哪些种类？

铸造轧辊是指将冶炼钢水或熔炼铁水直接浇注成型这一生产方式制造的轧辊种类。

铸造轧辊按材质又可分为铸钢轧辊和铸铁轧辊两类；按制造方法又可分为整体铸造轧辊和复合铸造轧辊两类。

What are the casting rolls and what are the main types of casting rolls?

The casting roller refers to the type of rolls produced by direct casting of molten steel or molten iron.

The casting roll can be divided into two types: cast steel roll and cast iron roll according to material quality. According to the manufacturing method，吊车轨， it can also be divided into two types: integral casting roll and compound casting roll.

19世纪下半叶欧洲炼钢技术的进步要求轧制更大吨位的钢锭，无论是灰铸铁或冷硬铸铁轧辊的强度均已不能满足要求。含碳量为0.4%～0.6%普通铸钢轧辊相应诞生。重型锻压设备的出现更使这种成分的锻造轧辊的强韧性得到进一步提高。

In the second half of the nineteenth Century， the progress of steelmaking technology in Europe requires larger tonnage steel ingots to be rolled. Neither the strength of gray iron or chilled cast iron rolls can meet the requirements. The ordinary cast steel roll with a carbon content of 0.4% to 0.6% is born accordingly. The emergence of he***y forging equipment makes the strength and toughness of the forging roll of this component further improved.

轧辊由辊身、辊颈和轴头二部分组成。辊颈安装在轴承中，并通过袖承座和压下装置把轧制力传给机架。铂头和连接轴相连接，传递轧制扭矩。轴头有三种主要形式；梅花轴头、万向轴头、带键槽的或圆柱形轴头。

The roll is of two parts of the roller body，吊车轨价格， the neck of the roll and the shaft head. The roll neck is installed in the bearing and passes through the sleeve bearing seat and the press down device to the rack. The platinum head is connected to the connecting shaft to transfer the rolling torque. There are three main forms of the shaft; the shaft of a plum， a universal shaft， or a cylindrical shaft with a keyway.
