Embodiment Construction

[0008] In the working part of the guide plate, a layer of wear-resistant alloy layer is prepared by casting infiltration technology, and the non-working part of the guide plate is formed by casting ordinary medium-carbon low-alloy steel; the wear-resistant alloy layer is made of high-carbon Ferrochrome powder 65%-75%, ferrovanadium powder 8%-12%, ferro-titanium powder 2%-6%, rare earth ferrosilicon powder 1%-1.2%, stir evenly, then add nickel-coated alumina particles 12%-18 %, finally add 2%-2.5% resin of the total weight of the above alloy, and further stir to make the resin evenly distributed in the alloy powder and nickel-coated alumina particles, and then apply it to the working part of the guide plate. After the resin is cured for 35 minutes , the temperature of 1560 ℃ -1600 ℃ medium carbon low alloy steel molten steel is directly poured into the casting mold, the alloy powder is under the action of high temperature molten steel, and after the molten steel around the ...

Abstract

Provided is a processing method for materials of a foreplate on a rolling mill. Materials of a non-working portion of the foreplate are formed by ordinary medium-carbon low-alloy steel in a pouring mode, a wear-resisting alloy layer is formed on a working portion of the foreplate in a cast-infiltration mode, and the wear-resisting alloy layer is made of a cast steel parent body. The foreplate produced by the processing method for the materials of the foreplate on the rolling mill is simple in production process, the service life of the foreplate is greatly prolonged, and production cost is reduced.

Description

technical field [0001] The invention relates to rolling equipment, in particular to a method for processing guide plate materials on a rolling mill. Background technique [0002] In the production of profile rolling mills, the guide plate is one of the auxiliary devices of the rolling mill and an indispensable mold. They bear the thermal load, impact, high-speed wear, extrusion and cooling of the hot billet during use, so the material is required to have high mechanical strength, hardness, wear resistance, impact toughness and oxidation resistance. and thermal fatigue resistance. Improving the life of the guide plate can not only increase the output of rolled steel, but also improve the surface quality of rolled products and reduce the labor intensity of workers. In my country, only guides and guards cost more than 2 billion yuan. Developing a suitable surface alloying technology for guides and guards and applying them to steel rolling equipment will surely promote the...
