Problems solved by technology

The tin layer can also be coated by hot-dip plating. The tin layer of the tin plate obtained by this method is thicker, and the amount of tin used is large. After tin plating, no purification treatment is required. The tin plate on the market is basically divided into two categories. Hard tinplate and soft tinplate, but most of the hard tinplates in the prior art have low hardness and cannot meet the needs of the market. Therefore, there is an urgent need for a new high-strength hard tinplate plate

Abstract

The invention relates to a high-strength tinned plate. The high-strength tinned plate is characterized by being composed of, by weight, 0.0045-0.0055% of carbon, 0.6-0.7% of manganese, 0.05-0.08% of aluminium, smaller than or equal to 0.025% of silicon, 0.025-0.03% of titanium, smaller than or equal to 0.015% of phosphorus, smaller than or equal to 0.025% of sulfur, smaller than or equal to 0.003% of nitrogen, and the balance iron and inevitable impurity elements. The hard tinned plate obtained by the technical scheme is relatively high in hardness, can meet various market requirements, and can be widely applied.

Description

technical field [0001] The invention relates to a tinplate, in particular to a high-strength tinplate and belongs to the technical field of tinplate production. Background technique [0002] Tinplate (commonly known as tinplate ） It refers to the steel plate with a thin layer of metallic tin on the surface. Tin plate is made of low carbon steel rolled into about 2mm thick steel plate, after pickling, cold rolling, electrolytic cleaning annealing, smoothing, edge trimming, and then cleaning, electroplating, remelting, passivation treatment, and oiling It is cut into finished products of tinplate, and the tin plating used for tinplate is high-purity tin (Sn>99.8%). The tin layer can also be coated by hot-dip plating. The tin layer of the tin plate obtained by this method is thicker, and the amount of tin used is large. After tin plating, no purification treatment is required. The tin plate on the market is basically divided into two categories. Hard tinplate and soft tin...
