Embodiment 1

[0027] Such as figure 1 As shown, the wear-resistant guide plate includes a matrix 1 made of cast steel plate material, and the outer surface of the matrix is ​​provided with a wear-resistant layer 2 made of an alloy material. The wear-resistant layer material includes the following components (weight percentage): Cu52.45%; Fe26.93%; Ni17.95%; Mn0.53%; Al0.36%; graphite powder 1.78%; The wear-resistant guide plate is made of copper-iron-nickel alloy, which has the advantages of high temperature resistance, wear resistance and low cost; at the same time, graphite powder is dispersed in the wear-resistant layer to increase the self-lubricating performance of the guide plate and has good mechanical strength. , can be used for a long time without the advantages of oil supply.

[0028] Such as figure 2 Shown is the manufacturing method of this wear-resistant guide plate, and it comprises the following steps:

[0029] a. Substrate annealing and degreasing: put the substrate into...

Embodiment 2

[0035] The base material of the wear-resistant guide plate provided in this embodiment is the same as that of Example 1, except that the material of the wear-resistant layer comprises the following components (percentage by weight): Cu52.6%; Fe25%; 20% Ni; 0.2% Mn; 0.6% Al; 1.5% graphite powder; the rest are impurities, and the graphite powder is 80 mesh graphite powder.

Embodiment 3

[0037] The base material of the wear-resistant guide plate provided in this embodiment is the same as that of Example 1, except that the material of the wear-resistant layer comprises the following components (percentage by weight): Cu51.5%; Fe30%; Ni 15%; Mn 0.8%; Al 0.1%; graphite powder 2.5%; the rest are impurities, and the graphite powder is 80 mesh graphite powder.

Abstract

The invention relates to a wear-resistant guide plate and a manufacturing method thereof, belongs to the technical field of machinery, and solves the problem that a wear-resistant guide plate is poorly wear-resistant in the prior art. The wear-resistant guide plate comprises a base body which is made of cast steel materials, and the outer surface of the base body is provided with a wear-resistant layer made of alloy materials comprising the following components, by weight, 25%-30% of Fe, 15%-20% of Ni, 0.2%-0.8% of Mn, 0.1%-0.6% of Al, 1.5%-2.5% of graphite powder and the balance of Cu powder and impurities. By the application of the wear-resistant layer made of the alloyed copper, iron and nickel materials, the wear-resistant guide plate has the advantages of high-temperature resistance, wear resistance and low cost; diffuse distribution of the graphite powder inside the wear-resistant layer allows the guide plate to be good in self-lubrication and mechanical strength and free of oil supply for long-term use.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to a guide plate during mechanical movement, in particular to a wear-resistant guide plate. Background technique [0002] The guide plate fits between the rolling mill stand and the roll chock to play a guiding role. The hardness range of the frame guide plate is usually HRC58-62, which is 4-5 degrees higher than that of the bearing seat guide plate. The hardness of the guide plate not only improves the wear resistance of the material, but also improves the tensile strength of the material, which can more effectively prevent scratches or nicks caused by friction. Since the guide plate is not only affected by the sliding friction of the bearing seat and the impact from the bearing seat, but also resists the corrosion and cavitation from the high-pressure water spray, the wear is extremely serious, and a single material can no longer meet the harsh requirements of the guide plate.
