Abstract

The invention discloses a guide roller and a preparation technique thereof. The guide roller comprises the raw material components by weight percent: 3.1-3.45% of C, 0.1-0.9% of Si, 0.1-0.4% of Mn, 0.01-0.03% of P, 0.01-0.03% of S, 24-25% of Cr, 0.4-0.6% of Mo, 0.9-1% of V, 2-3% of W, 0.05-0.1% of rare earth and the balance of Fe. The preparation technique of the guide roller comprises the steps of: firstly, making the guide roller by precision casting, treating by the guide roller by annealing, rough machining, quenching, tempering and finish machining, and obtaining the finished product. The prepared guide roller is low in cost, long in service life and good in high-temperature oxidation resistance, and has the advantages of high-temperature strength, shock resistance, high-temperature toughness and high-temperature frictional wear resistance.

Description

Technical field: [0001] The invention mainly relates to an alloy material and a processing method thereof, in particular to a guide roller and a preparation process thereof. Background technique: [0002] The guide roller is an important part of the rolling guide device for rolling steel, which is used to transport the profiles and wires to make them enter the rolling mill smoothly. The working environment is very bad. The red-hot steel above 900°C passes through the guide continuously, and at the same time it needs to be sprayed with water to cool it. Rolling production efficiency. In addition, when the guide roller is in use, it is easy to cause steel sticking, which affects the quality of rolled steel. The root cause of sticking steel is that under the high temperature, rapid cooling and rapid heating working conditions of the guide, it will weld with the red steel passing through quickly, which requires that the material of the guide roller must have high thermal stre...
