TS1770 Silicon Steel Sheet Coating Adhesion Tester

1. Summary

TS1770 is a device specially used to test the coating adhesion of silicon steel sheets. It consists of a fixed bracket, 10mm, 20mm and 30mm brass cylinders. It can be used for coating adhesion rating on electrical steel. It can be widely used in iron and steel metallurgical plants, transformer/motor manufacturers, etc. It is an indispensable equipment for performance testing of electrical steel. Reference standard: GB/T 2522-2017 "Electrical steel strip (sheet) coating insulation resistance and adhesion test method".

2. Features

• Device: It is a smooth-surfaced brass cylinder with diameters of 10mm, 20mm, and 30mm, and a tolerance of -0.5mm ~ +0.1mm. All three cylinders are fixed on the same bracket.

• Specimen: Cut a representative specimen parallel to the rolling direction at a distance of not less than 40mm from the edge of the steel strip (piece), and the coating of the specimen must not be damaged. The size of the specimen width is 30 ± 0.2mm, length is 280mm~320mm. If there are special requirements, the supply and demand parties will negotiate and determine.
