Cold Rolled Lamination Steel

Electrical steel is usually manufactured in cold rolled strips less than 2 mm thick.

Cold rolled lamination steel.

Cold rolled motor lamination sheet is a special type of cold rolled steel sheet product that is produced to maximize the performance of the products for use as electro magnetic core materials for electrical equipment components. It is a semi processed sp material produced via batch annealing and temper rolling rather than on dedicated continuous decarburizing and annealing lines as emphasized in fig. These grades are specifically developed for magnetic applications not requiring extremely low core losses or for those applications not requiring magnetic characteristics of high silicon electrical steel. Also called cold rolled lamination steel this material is the lowest cost material for volume applications.

1 integrated mills lacking the specialized continuous annealing lines required for noes were provided. The steels used for these applications are designed to. In terms of tonnage this is probably the most common material in use today. Cold rolled steel has been rolled at room temperature below its recrystallization temperature which enables better control over finished product shape thickness dimensions and surface finish.

Our crml meets astm a726 standards for use in the electromagnetic core of fractional motors and other electrical equipment and components. We also offer thin gauge low loss grades for special applications with technical support to better understand customer needs and recommend most cost effective. View product details of cold rolled transformer steel laminations non oriented transformer core laminations from jiangyin chuangjia electrical appliance company manufacturer in ec21. Lamination crml will remain a priority far into the future.

Ease of stamping and low tool wear help to contribute to the low cost of finished laminations. Cold rolled transformer steel laminations non oriented transformer core laminations id 10475949. Big river steel has taken our cold rolled manufacturing capabilities even farther by providing crml steels. Crml steel development was enabled by improvements to the production practices for low carbon cold rolled steel.

Small hysteresis area resulting in low power loss per cycle low core loss and high permeability. Crml is an electrical grade of steel containing low amounts of alloy. Cold rolled motor lamination crml astm a726. Electrical steel lamination steel silicon electrical steel silicon steel relay steel transformer steel is an iron alloy tailored to produce specific magnetic properties.

1 1 this specification covers cold rolled carbon sheet steel used for magnetic applications. These include electric motors generators and transformers. Motor lamination steel is a specific cold rolled product tailored to create electromagnetic core materials for electrical equipment and components.
