Steel for excavator bucket teeth and preparation method of steel
The invention discloses steel for excavator bucket teeth and a preparation method of the steel. The steel comprises the following components including C, Cr, Si, Ti, Mn, Ni, Nb, Mo, V, W, Zr, RE, B and Fe. The preparation method of the steel comprises the steps that a blank obtained through raw material smelting, pouring and cooling is heated to 800-850 DEG C, heat preservation is conducted for 8-13 min, after cooling is conducted to 450-500 DEG C, the temperature is increased to 730-770 DEG C, heat preservation is conducted for 25-45 min, cooling to 400-430 DEG C is carried out, the temperature is increased to 700-730 DEG C, heat preservation is conducted for 40-60 min, heating to 950-1100 DEG C is carried out after air cooling, heat preservation is conducted for 5-12 min, air cooling iscarried out to 500-650 DEG C, then water cooling is carried out, heating to the temperature T1 is carried out, heat preservation is conducted for 50-100 min, furnace cooling is carried out, heating iscarried out to the temperature T2, heat preservation is conducted for 60-150 min, and air cooling is carried out, wherein T1 is equal to 210-350 DEG C, and T2 is equal to the sum of T1 and 30 DEG C.
本发明公开了一种挖掘机斗齿用钢及其制备方法，所述钢的成分包括C、Cr、Si、Ti、Mn、Ni、Nb、Mo、V、W、Zr、RE、B、Fe。所述钢的制备方法包括：将原料熔炼、浇注、冷却得到的坯料加热至800‑850℃保温8‑13min，冷却至450‑500℃后升温至730‑770℃保温25‑45min，冷却至400‑430℃后升温至700‑730℃保温40‑60min，空冷后加热至950‑1100℃保温5‑12min，风冷至500‑650℃后水冷，加热至温度T1后保温50‑100min，炉冷后加热至温度T2后保温60‑150min，空冷；T1＝210‑350℃，T2＝T1+30℃。
