Single Reduced Cold-Rolled Tinplate Steel

OVERVIEW

Overview of Single Reduced Cold-Rolled Tinplate Steel

Single Reduced Cold-Rolled Tinplate steel is a single cold-rolled tinplate, which is a steel produced by cold rolling process and tinned. Its production process involves material selection, production process, surface treatment, coating treatment, dimensional accuracy, performance testing and other aspects. Relevant international standards such as ISO 1111 - 1:1983 EN have clear provisions for its manufacturing and testing methods, which are applicable to the manufacturing and quality control of various types of products such as metal plates, coated plates, composite plates, etc.

Quality improvement and process measures related to Single Reduced Cold-Rolled Tinplate steel

1. The impact and improvement of hot-rolled plate quality on subsequent processing:

Take Q345 hot-rolled steel plate as an example. The cracks caused by cold bending can be avoided by adopting heating-cold bending process and improving steel purity. This has reference significance for the quality control of raw material hot-rolled plates in the production of Single Reduced Cold-Rolled Tinplate steel.

2. Process methods to improve the performance of hot-rolled plates:

Refining the grains of hot-rolled plates and improving the uniformity of hot-rolled plate structures can improve the cold rolling and repeated bending performance of hot-rolled plates, which helps to provide better quality cold-rolled base materials for the production of Single Reduced Cold-Rolled Tinplate steel.

3. Measures to reduce the yield strength of hot-rolled plates:

The reduction of the nitrogen mass fraction in steel can reduce the yield strength of hot-rolled plates and meet the requirements of cold-rolled base materials, which has important reference value for controlling the performance of raw materials in the production of Single Reduced Cold-Rolled Tinplate steel.


Application fields of Single Reduced Cold-Rolled Tinplate steel

1. Motor manufacturing field:

In motor manufacturing, this steel can be used for some structural components to improve motor performance. For example, the YC series motor uses cold-rolled silicon steel sheets (belonging to the category of cold-rolled steel plates) and high-quality bearings, and the vibration noise is far lower than the national standard requirements.

2. Resistance furnace manufacturing field:

This series of resistance furnaces are rectangular in shape, and the furnace shell is made of angle steel and cold-rolled plate welded, and the surface is electrostatically sprayed. The cold-rolled plate here contains the characteristics of cold-rolled plate similar to Single Reduced Cold-Rolled Tinplate steel.

3. Container manufacturing field:

Some equipment with shells made of cold-rolled plates, such as some container products, have shells made of cold-rolled plates, and the inner liner and upper cover are made of high-quality stainless steel plates stamped and welded, and the surface is electrostatically sprayed, which reflects the application of this type of steel in the manufacture of container shells.
