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 heavy forging equipment makes the strength and toughness of the forging roll of this component further improved.

由于轧制过程是连续的过程，圣霖国际吊车轨报价，因此操作人员需要不断检测轧辊状况，使生产出来的产品满足用户对更严格的公差和表面质量的要求。

As the rolling process is a continuous process， the operator needs to continuously detect the roll status to meet the more stringent tolerance and surface quality requirements of the products produced.

实践表明，圣霖国际吊车轨价格，带双镀槽的轴头在使用过程中，镶槽壁容易崩裂，目前常用易加工的带平台的袖头代替双因槽的抽头。

直径超过400mm的冷轧轧辊，在锻造后，多半在中心馒一个670一250mm的通7L。这样，一力面可以使轧辊经热处理店的内应力分朽均勾；另一方面在轧辊表面淬火时，可对轧辊通水冷却，提高淬火效果。

Practice shows that，圣霖国际吊车轨批发， with double bath head is in use， insert groove wall is easy to crack， at present common processing platform with the cuff instead of double slot for tap.

Cold roll diameter of more than 400mm，圣霖国际吊车轨， after forging， mostly in the 7L center. A 670 250mm. So， on one hand can make the roller stress heat treatment shop allocation hook are; on the other hand， the roll surface quenching， the water cooling roller， improve the quenching effect.
