Detailed description of the invention
Below the invention will be further described for the description by detailed description of the invention, butThis is not limitation of the present invention, and those skilled in the art are according to of the present invention basicThought, can make various amendments or improvement, but only otherwise depart from base of the present inventionThis thought, all within the scope of the present invention.
The preparation of embodiment 1 abrasion-resistant stee
The consisting of of abrasion-resistant stee (in % by weight):
0.40% carbon;
0.60% chromium;
0.80% silicon;
0.70% manganese;
1.5% nickel;
0.8% molybdenum;
0.25% vanadium;

The 50kg steel material with mentioned component composition is placed in to 50kgSS81-22 intermediate frequencyMelting 6 hours in coreless induction furnace, in view of alloying element can be sent out in fusion processRaw oxidization burning loss, adds cobalt and niobium in last hour of melting, and molten steel temperature reaches1600 DEG C, cast subsequently, in this casting cooling velocity be 1.8 DEG C/min withForm ingot. Ingot is kept 8 hours at 900 DEG C, then at 550 DEG C, protectHold 60 minutes. After this use 500 tons of hammer forging machines to carry out forge hot, make like thisAbrasion-resistant stee 1.
The preparation of embodiment 2 abrasion-resistant stees 2
Prepare abrasion-resistant stee 2 according to the mode identical with embodiment 1, difference isDo not use cobalt.
The preparation of embodiment 3 abrasion-resistant stees 3
Prepare abrasion-resistant stee 3 according to the mode identical with embodiment 1, difference isDo not use niobium.
Experimental example 1
Measure the Brinell hardness of abrasion-resistant stee 1-3 according to GB/T231.1-2009. Result is as follows:The Brinell hardness of abrasion-resistant stee 1 is 289HRC, and the Brinell hardness of abrasion-resistant stee 2 is 216HRC,The Brinell hardness of abrasion-resistant stee 3 is 232HRC. The Brinell hardness of abrasion-resistant stee 1 and abrasion-resistant stee 2 withAbrasion-resistant stee 3 is compared, and has significant difference (P < 0.05).
