Embodiment Construction

[0012] A hard tinned thin steel plate, characterized in that the chemical composition (weight percentage) of the original plate is C: 0.05-0.07%%, Si≤0.1%, Mn: 0.20-0.30%, P≤0.020%, S≤0.020%, Alt: 0.010-0.060%, N≤0.0060%, the balance is Fe and some unavoidable impurity elements; its production methods include: steelmaking→continuous casting→hot rolling→combined acid rolling→continuous annealing→double stand leveling→ Electroplated tin.

[0013] Below in conjunction with embodiment and comparative example the present invention will be further described:

[0014] (1) Steelmaking: Steelmaking organizes conventional production according to the design requirements of the composition. The production process is as follows: after smelting in the mixed iron furnace, it enters the pouring station for desulfurization, slag removal, converter, argon blowing station, CAS treatment, continuous casting, plate The billet surface quality is good. The chemical composition of molten steel is a...

Abstract

The invention relates to a hard tinned sheet steel produced from low carbon aluminium killed steel so as to solve the technical problems of easy appearance of local edge waves during current pickling rolling production of tinned sheet steel, high incidence of surface iron oxide scale during continuous annealing production, high yield ratio of tin plates, undesirable stamping processing and the like. The hard tinned sheet steel and its raw sheet comprise the following chemical components (by weight): 0.05-0.07% of C, less than or equal to 0.1% of Si, 0.20-0.30% of Mn, less than or equal to 0.020% of P, less than or equal to 0.020% of S, 0.010-0.060% of Alt, less than or equal to 0.0060% of N, and the balance Fe and some inevitable impurity elements. The production method of the hard tinned sheet steel includes: steelmaking, continuous casting, hot rolling, combined pickling rolling, continuous annealing, double-stand tempering, and electrotinning. The hard tinned sheet steel produced in the invention has the advantages of small production control difficulty, excellent appearance quality, thin specification, stable hardness, and good stamping processing performance, etc., can meet the use requirements of high-speed canning, and can be widely used as a food cans, beverage cans, aerosol cans and other packaging materials.

Description

technical field [0001] The invention relates to a thin steel plate, in particular to a hard tinned thin steel plate and a production method thereof; the hard tinned thin steel plate and the production method thereof can improve product quality and stamping processing performance. Background technique [0002] Tinplate, commonly known as "tinplate", refers to cold-rolled low-carbon thin steel plate or steel strip coated with commercial pure tin on both sides, which combines the strength and formability of steel with the corrosion resistance, weldability and beautiful appearance of tin In one material, it has corrosion resistance, non-toxicity, high strength and good ductility, and is widely used in packaging fields such as food cans, beverage cans, aerosol cans, and chemical cans. [0003] The phase diagram of Fe—C binary alloy shows that: with the increase of C content in steel, the solid phase transition temperature Ar3 of γ→α decreases. At present, the C content of this k...
