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 tin plate and a production method thereof. The high strength tin plate is characterized by comprising the following components in mass percentage: 0.0040-0.0055% of C, 0.5-0.7% of Mn, 0.04-0.08% of Al, less than or equal to 0 .025% of Si, 0 .025-0 .03% of Ti, less than or equal to 0.015% of P, less than or equal to 0 .025% of S, less than or equal to 0.003% of N, and the balance of Fe and inevitable impurity elements; the processing technology comprises the following steps: steelmaking, continuous casting, hot rolling, acid rolling, annealing, leveling and tinning, wherein the hot rolling temperature is 1500 DEG C, the finishing temperature of hot rolling is 1000 DEG C, and the annealing temperature is 800 DEG C. The rigid tin plate prepared by adopting the technical scheme is higher in hardness, can meet various requirements in the market, and has a wide application range.
Description
technical field [0001] The invention relates to a tinplate, in particular to a high-strength tinplate and a production method thereof, belonging 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 categori...
