Low-alloy steel plates have low carbon content, and because ferrosilicon is not used for deoxidation, the silicon content in steel is often <0.07%. The outer layer of rimmed steel is crystallized in a rimmed state, so the surface layer is pure and dense, the surface quality is good, and the Zhengzhou low alloy steel plate steel SA283 Gr.C+ar has good processing performance. Rimmed steel does not have large concentrated shrinkage cavities, uses less deoxidizer, and the cost of steel is low.
The correct choice of billet type, section shape, size and weight are of great significance to steel SA283 Gr.C+ar steel rolling production. Steel rolling production has certain technical requirements for raw materials, such as steel type, section shape, size, weight, and surface quality. The consideration of these technical requirements is necessary to ensure the quality of steel. It should also be specifically considered when determining and selecting the blank. The steel SA283 Gr.C+ar rolling method can be divided into cold rolling and hot rolling according to the rolling temperature.
On November 1st, our company organized some of company staff to visit Zhengzhou Children Welfare Institute, and gave children cookies and toys, as well as concerns to the Children. With the development of the society, disabled children gets increasing concerns and help from all walks of life. Fortunately, Chinese Government gives high concern to the handicapped children and has built Children Welfare Institutes all over the country to guarantee their lives.
