Embodiment 1-7

[0055] The high-strength steel sheet for glass lining in the above-mentioned embodiment is prepared by the following steps:

[0056] (1) Smelting and casting: 300t top-bottom combined blowing converter is used for smelting steel, and molten steel is cast into slabs by continuous casting machine;

[0057] (2) Hot rolling: the heating temperature before the casting billet rolling is 1150~1250℃, the holding time=t×(0.5~1.5), where t is the thickness of the slab, the unit is mm, and the unit of holding time is min; control The rolling temperature of rough rolling is 1100~1200℃, and the deformation is ≥50%; after the rough rolling, water is sprayed to cool, and the finish rolling temperature is controlled to 920~1000℃, the final rolling temperature is 870~920℃, and the deformation is ≥60%;

[0058] (3) Cooling: control the average cooling rate ≤ 10℃ / s. The cooling method can adopt water spray cooling or slow cooling.

[0059] In addition, it should be noted that in other embodiments, in o...

Abstract

The invention discloses a high-strength steel plate with excellent double-face enamelling performance and used for glass lining. The high-strength steel plate with excellent double-face enamelling performance and used for glass lining comprises, by mass, 0.06 to 0.15% of C, 0.16 to 0.50% of Si, 0.6 to 2.0% of Mn, 0.010 to 0.035% of S, 0.001 to 0.05% of Al, Als<=0.05%, 0.15 to 0.25% of Ti, 0.0035 to 0.010% of N, 0 to 0.10% of Nb, and the balance Fe and other inevitable impurities. The microstructure of the high-strength steel plate possesses ferrite and TiN particles taken as a precipitated phase; the surfaces of the TiN particles are planes; and irreversible small cavities are formed between the TiN particles and the ferrite crystal grains with curved surfaces. The invention also disclosesa manufacturing method of the high-strength steel plate with excellent double-face enamelling performance and used for glass lining. The high-strength steel plate is excellent in double-face enamelling performance and strength, and no fishscaling is caused.

Description

Technical field [0001] The invention relates to a high-strength steel plate and a manufacturing method thereof, in particular to a high-strength steel plate for glass lining and a manufacturing method thereof. Background technique [0002] The glass lining process is a process in which glassy enamel containing high silica content is coated on the surface of the steel plate base after processing, and then after high temperature sintering, the enamel is firmly combined on the surface of the steel plate base to form a composite material. This composite material has the common advantages of glass stability and steel strength, good wear resistance, and good corrosion resistance to various acids, alkalis, and organic solvents. Glass-lined technology is mainly used in the processing and manufacturing of glass-lined equipment and glass-lined accessories, such as glass-lined reactors, glass-lined storage tanks, glass-lined stirrers, etc., and is widely used in petrochemical, medical and p...
