Embodiment 1

[0035] refer to Figure 1-2 , a high-performance alloy steel flange, including a connecting plate 1, the connecting plate 1 is arranged in a circle, the middle part of the connecting plate 1 is provided with a round hole 3 passing through the connecting plate 1, and both sides of the connecting plate 1 are fixed with ring plates 4. The diameter of the annular plate 4 and the diameter of the circular hole 3 are set to be the same, the center of the circular plate 4 and the center of the circular hole 3 are located on the same vertical line, and the outer side of the connecting plate 1 is uniformly provided with a plurality of connecting plates 1 The threaded holes 2 are distributed in a circular array, and the outer side of the connecting plate 1 is coated with a wear-resistant layer 5, and the wear-resistant layer 5 is specifically a zinc-chromium alloy layer, and the zinc-chromium alloy has good wear resistance. As a result, the protection effect on the side of the connecting...

Embodiment 2

[0056] refer to Figure 1-2 , The difference between this embodiment and Embodiment 1 is that the high-performance alloy steel flange includes a connecting plate 1, the connecting plate 1 is arranged in a circular shape, and the middle part of the connecting plate 1 is provided with a round hole 3 penetrating through the connecting plate 1, The both sides of connecting plate 1 are all fixed with annular plate 4, and the diameter of annular plate 4 is identical with the diameter size of circular hole 3, and the center of circle of annular plate 4 and the center of circle of circular hole 3 are positioned on the same vertical line, and connecting plate 1 A plurality of threaded holes 2 penetrating through the connecting plate 1 are evenly opened on the outer side of the connecting plate 1, and the plurality of threaded holes 2 are distributed in a circular array. The outer side of the connecting plate 1 is coated with a wear-resistant layer 5, and the wear-resistant layer 5 is sp...

Embodiment 3

[0077] refer to Figure 1-2 , The difference between this embodiment and Embodiment 1 and Embodiment 2 is that a high-performance alloy steel flange includes a connecting plate 1, which is arranged in a circle, and the middle part of the connecting plate 1 is provided with a through connecting plate 1, both sides of the connecting plate 1 are fixed with an annular plate 4, the diameter of the annular plate 4 is the same as that of the circular hole 3, and the center of the annular plate 4 and the center of the circular hole 3 are located at the same vertical On the line, a plurality of threaded holes 2 penetrating through the connecting plate 1 are evenly opened on the outer side of the connecting plate 1, and the plurality of threaded holes 2 are distributed in a circular array. The outer side of the connecting plate 1 is coated with a wear-resistant layer 5, and the wear-resistant layer 5 is specifically It is a zinc-chromium alloy layer, and the zinc-chromium alloy has a go...

Abstract

The invention relates to the technical field of flange manufacturing, in particular to a high-performance alloy steel flange. The high-performance alloy steel flange comprises a connecting plate, wherein the connecting plate is circular, a round hole penetrating through the connecting plate is formed in the middle of the connecting plate, a wear-resistant layer is plated on the outer side of the connecting plate, and the wear-resistant layer is specifically a zinc-chrome alloy layer. The invention further provides a manufacturing method of the high-performance alloy steel flange. The manufacturing method comprises the steps of raw material processing, shell membrane preparation, casting and heat treatment. When the high-performance alloy steel flange is manufactured, multiple metallic elements are added to be molten, a product formed by casting is subjected to heat treatment, and the performance and strength of the flange are greatly improved through updating of materials and the preparation process, so that the service life of the flange is prolonged.

Description

technical field [0001] The invention relates to the technical field of flange preparation, in particular to a high-performance alloy steel flange and a manufacturing method thereof. Background technique [0002] Flange is otherwise known as flange flange or flange. Flanges are parts that are connected to each other between shafts and are used for connection between pipe ends; they are also useful for flanges on equipment inlets and outlets, And can be used as connection between two equipments, example reducer flanges. Flange connection or flange joint refers to a detachable connection consisting of flanges, gaskets and bolts connected to each other as a combined sealing structure; [0003] Due to the low strength of the flanges on the existing market, the flanges may crack or even break after being used for a period of time, which shortens the service life of the flanges. Contents of the invention [0004] The purpose of the present invention is to solve the shortcomings...
