To reach above-mentioned purpose, technical scheme is as follows：
A kind of multi-functional roll piercing mill once perforated guide plate, its material includes according to mass percent：C:1.9%-
2.1%, Si:0.8%-1.2%, Mn:0.3-0.6%, Cr:25%-27%, Ni；8%-10%, Mo；0.5%-0.7%, Ti:
0.3%-0.5%, P<0.035%, S<0.035%, surplus is iron.
It is preferred that, the mass percent of the carbon is 2%
It is preferred that, the mass percent of the silicon is 0.9%-1.0%.
It is preferred that, the mass percent of the manganese is 0.5%.
It is preferred that, the mass percent of the chromium is 26%.
It is preferred that, the mass percent of the nickel is 9%.
It is preferred that, the mass percent of the molybdenum is 0.6.
It is preferred that, the mass percent of the titanium is 0.4%.
Beneficial effect：Using the guide plate of above-mentioned technique productions, matrix is austenite, and structure stability is good, and high temperature is strong
Degree, toughness, thermal fatigue resistance energy are good；The high high silicon of chromium ensures that guide plate has a high inoxidizability, higher carbon content and chromium,
The addition of molybdenum alloy, it is ensured that guide plate matrix has enough carbide reinforced phases, intensity and hardness are improved, and heat resistance, wearability are good.
Rational manufacturing process ensure that guide plate dense structure, crystal grain refinement, no casting flaw；Carbide reinforced phase particle is tiny, and
And be uniformly distributed, guide plate combination property is greatly improved.The guide plate manufactured using above-mentioned technique, uses effect on multi-functional roll piercing mill
Fruit is good, averagely wears steel number more than 1000, is twice of high chromium guide plate service life, close to the use longevity of nickelic guide plate
Life.Guide plate manufacturing cost is only 1/3rd of nickelic guide plate.
