Abstract
A bullet-resistant structureal alloy steel cotnains C (0.08 or 0.40). Si (0.15 or 0.35), Mn (0.70 or 1.30), P (less than or equal to 0.03), S (less than or equal to 0.03), Gr (0.50 or 0.80), Ni (1.40 or 1.90), Mo (0.50 or 0.80), and V (0.05 or 0.15). Its advantages include high strength and toughness (resulting in smaller thickness), and good appearance.
Description
The present invention relates to the improvement of the production method of bullet-resistant structural alloy steel.
Bullet-resistant structural alloy steel not only is applied on military equipment, at present on civil equipment, for example: also be widely used on the armoured van, and the requirement to shellproof steel alloy mainly is that thin thickness is a little on the civil equipment, volume is light and handy, so that outward appearance is quite a lot of, but the thickness of existing bullet-resistant structural alloy steel is desirable not to the utmost.
Purpose of the present invention just provides the less bullet-resistant structural alloy steel of a kind of its thickness.
The object of the present invention is achieved like this: the present invention adopts conventional smelting process substantially, only is that the amount in the chemical ingredients of adding changes to some extent, and its concrete amount is:
C Si?Mn P S Cr Ni Mo V
0.18 0.15 0.70 ≤0.030 ≤0.030 0.50 1.40 0.50 0.05
0.40 0.35 1.30 0.80 1.90 0.80 0.15
Major advantage of the present invention:
Owing to adopted chemical ingredients of the present invention, make bullet-resistant structural alloy steel that melting comes out under the constant situation of intensity, toughness, its thickness can reduce, and therefore, volume reduces thereupon, makes image appearance better, provides convenience for using to install to wait.
Smelting process of the present invention:
Adopt electric furnace+VOD or electric furnace+LF technology;
Wherein VOD or electric furnace are furnace outer refining process.
Steel plate can adopt pad to roll as-annealed condition or Cold Rolled Strip.
The size of steel plate and franchise are pressed YB/T5132-93 and are carried out.
Surface quality requires: surface of steel plate such as must not have layering, crackle, bubble, scabs and be mingled with at defective.
Inspection rule: press YB/T5132-93 and carry out.
