Embodiment 1

[0020] A production process of stainless steel wire, comprising the following steps:

[0021] 1) Configure the furnace charge, which is composed of the following alloy elements in weight percentage: C0.06%, Si0.50%, Mo0.50%, Mn1.5%, Ni0.45%, Al1.45%, S0.01 %, Cr17.0%, Ti1.01%, the balance is Fe and unavoidable impurities;

[0022] 2) Put the charge into the medium-frequency induction furnace for smelting. After the charge is completely melted, add a slagging agent with a weight of 1.5% of molten steel to make slag, remove the slag, then add low-carbon ferromanganese and ferrosilicon for deoxidation, and adjust the composition. When the temperature of the molten steel reaches 1660°C, insert 1.25kg / t aluminum cake into the molten steel for final deoxidation;

[0023] 3) After the final deoxidation is completed, the furnace is tilted to tap the steel. The tapping temperature is 1600°C. Samples are taken in the ladle to analyze the chemical composition of the finished molten stee...

Embodiment 2

[0031] A production process of stainless steel wire, comprising the following steps:

[0032] 1) Configure the furnace charge, which is composed of the following alloy elements in weight percentage: C0.05%, Si0.80%, Mo0.45%, Mn2.0%, Ni0.40%, Al1.30%, S0.02 %, Cr15.0%, Ti1.01%, the balance is Fe and unavoidable impurities;

[0033] 2) Put the charge into the medium-frequency induction furnace for smelting. After the charge is completely melted, add a slagging agent of 1% by weight of molten steel to make slag, remove the slag, then add low-carbon ferromanganese and ferrosilicon for deoxidation, and adjust the composition. When the temperature of the molten steel reaches 1650°C, insert 1kg / t of aluminum cake into the molten steel for final deoxidation;

[0034] 3) After the final deoxidation is completed, the furnace is tilted to tap the steel. The tapping temperature is 1580°C. Samples are taken in the ladle to analyze the chemical composition of the finished molten steel. The...

Embodiment 3

[0042]A production process of stainless steel wire, comprising the following steps:

[0043] 1) Configure the furnace charge, which is composed of the following alloy elements in weight percentage: C0.08%, Si0.30%, Mo0.65%, Mn1.20%, Ni0.50%, Al1.60%, S0.01 %, Cr20.0%, Ti1.02%, the balance is Fe and unavoidable impurities;

[0044] 2) Put the charge into the medium-frequency induction furnace for smelting. After the charge is completely melted, add a slagging agent with a weight of 2% of molten steel to make slag, remove the slag, then add low-carbon ferromanganese and ferrosilicon for deoxidation, and adjust the composition. When the temperature of the molten steel reaches 1680°C, insert 1.5kg / t aluminum cake into the molten steel for final deoxidation;

[0045] 3) After the final deoxidation is completed, the furnace is tilted to tap the steel. The tapping temperature is 1620°C. Samples are taken in the ladle to analyze the chemical composition of the finished molten steel. ...

Abstract

The invention discloses a process for producing a stainless steel wire. The furnace burden selected by the process is prepared from the following alloy elements in percentage by weight: 0.05-0.08 percent of C, at most 0.80 percent of Si, 0.45-0.65 percent of Mo, at most 2.0 percent of Mn, 0.40-0.50 percent of Ni, 1.30-1.60 percent of Al, at most 0.02 percent of S, 15.0-20.0 percent of Cr, 1.01-1.02 percent of Ti and the rest of Fe and inevitable impurities. Under the condition that the content of Ni is reduced, the process ensures the comprehensive performance index of the stainless steel wire and therefore is beneficial to reducing the cost.

Description

technical field [0001] The invention relates to the technical field of metal material processing, in particular to a production process of stainless steel wire. Background technique [0002] Stainless steel mesh is a mesh product made of stainless steel wire, which is widely used in mining, petroleum, chemical, food, medicine, machinery manufacturing and other industries. Stainless steel wire can not only make stainless steel mesh, but also make various other stainless steel products. The performance of stainless steel wire directly affects the performance of its products. Stainless steel wire is made of stainless steel, and with the development of the times, various types of stainless steel have appeared on the market. For example, since the 1960s, martensitic Cr-Ni stainless steel has been developed, which has better ductility and toughness. However, in recent years, the price of Ni has risen, and the cost and selling price of stainless steel often fluctuate with the ri...
