Embodiment Construction

[0018] Below in conjunction with embodiment and accompanying drawing ( Figure 1-Figure 2 ) to illustrate the present invention.

[0019] The product and method of implementing a silicon-vanadium steel plate with improved anti-ballistic performance of the present invention are as follows: smelting in a 180-ton converter, refining in an LF furnace and a RH furnace, and the chemical composition is shown in Table 1. Continuous casting is used for casting. The slab is hot-charged, the heating temperature is 1200°C, the furnace residence time is 180min, the final rolling temperature is controlled at 850-900°C, and air-cooled after rolling. The quenching temperature of the steel plate is 850-950°C, the holding time is the plate thickness × (2-3) min / mm, the tempering temperature of the steel plate is 150-220°C, and the holding time is the plate thickness × (3-5) min / mm, The specific process parameters are shown in Table 2. Table 3 is the test data of mechanical properties. The re...

Abstract

The invention relates to a silicon vanadium steel plate with promoted bulletproof performance and a manufacturing method. The bulletproof performance means the capacity of the silicon vanadium steel plate to resist against bullet shooting or glass breaking. The silicon vanadium steel plate can meet the practical requirements of stability and light weight. The silicon vanadium steel plate comprises the following chemical elements by weight percent: 0.28-0.43% of C, 0.3-2.0% of Si, 0.3-1.0% of Mn, 0.3-1.5% of Cr, 0.3-3.0% of Ni, 0.1-0.6% of Mo, 0.03-0.12% of V, not more than or equal to 0.03% of inevitable impurities and the balance of Fe.

Description

technical field [0001] The invention relates to bulletproof steel plate technology, in particular to a silicon vanadium steel plate with improved bulletproof performance and a manufacturing method thereof. The bulletproof performance refers to the ability of the silicon vanadium steel plate to resist bullets or fragments, and to meet the practical requirements of stability and light weight. The silicon-vanadium steel plate refers to the steel plate containing both silicon and vanadium, wherein vanadium can play the role of MC-type carbide precipitation strengthening and / or fine-grain strengthening of hindering grain growth, and the MC-type refers to metal Or the crystal structure of metalloid elements combined with carbon. The silicon vanadium steel plate with improved bulletproof performance of the present invention can respectively obtain a high-performance bulletproof steel plate with a tensile strength not less than 1700 MPa and a high-performance bulletproof steel plate w...
