Formula of austenite heat-resisting alloy mesh belt wire for continuous mesh belt furnace and preparation method of mesh belt wire

Abstract

The invention discloses a formula of an austenite heat-resisting alloy mesh belt wire for a continuous mesh belt furnace and a preparation method of the mesh belt wire. The austenite heat-resisting alloy mesh belt wire consists of the following components in percentage by weight: 0.01-0.20% of C, 0.005-3.5% of Si, 0.01-2.5% of Mn, less than or equal to 0.035% of P, less than or equal to 0.030% of S, 22-27% of Cr, 18-26.0% of Ni, 0.05-2.5% of Co, 0.05-1.0% of Nb, 0.05-0.25% of Mo, 0.02-0.50% of N, 0.05-1.0% of W, added mixed metal rare-earth alloy that contains 0.003-0.50% of rare earth, and the balance of Fe and inevitable impurities. The austenite heat-resisting alloy mesh belt wire is provided in order to overcome the problems of a mesh belt wire for an existing continuous heat treatment furnace which is short in service life and is easy to become deformed and to cause brittle fracture. The austenite heat-resisting alloy mesh belt wire can further improve the high-temperature strength of austenite heat-resisting alloy, prolong service life and significantly reduce an effect of embrittlement.

Description

technical field [0001] The invention relates to the technical field of manufacturing austenitic heat-resistant alloy mesh belt wire, in particular to a formulation of austenitic heat-resistant alloy mesh belt wire for a continuous mesh belt furnace and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, the demand for continuous production lines of automated heat treatment equipment in the industrial field is becoming more and more important. Continuous mesh belt heat treatment furnace is an electric furnace that carries out continuous heat treatment by mesh belt conveying workpieces in a controlled atmosphere.

Problems solved by technology

With the influence of temperature and atmosphere, the mesh wire will be brittle and broken after a long time, and regional holes will appear in the mesh belt. It is very difficult to repair this situation. The patent application number is 200680020362.0. Application No. Ping 2-175842 Invention Patent Disclosed "Method for Manufacturing Stainless Steel for Atomic Furnace Core Machines"

The comprehensive mechanical properties of these two kinds of austenitic stainless steel materials cannot meet the steel wire for austenitic heat-resistant alloy mesh belt used in a continuous mesh belt furnace of the present invention.

At present, the mesh belt wires used in my country generally have a short service life, and they are only used in low-end continuous heat treatment furnaces. Most of the mesh belt wires used in high-end heat treatment mesh belt furnaces rely on imported materials to weave mesh belts after drawing.
