Abstract
The invention discloses a high-strength wear resistant complex brass melting technology. The technology comprises the following steps: adopting a line-frequency cored induction furnace to melt alloy, wherein the alloy comprises 2.8-3.4% of Mn, 2.8-3.2% of Al, 0.7-1.1% of Si, 0.3-0.5% of Ni, 0.15-0.25% of Cr, 61-63% of Cu, and the balance of Zn; adding 2/3 of Cu; adding charcoal; fusing; sequentially adding Si, Mn, Cr, Al, 1/3 of Cu and Zn; stirring; adding cryolite; and extracting slag, and discharging. The technology is based on hot working, and has the advantages of short process flow and high added values. The inside of ingot blanks difficultly has slag inclusion, loosening, segregation and other defects, and has stable quality.
Description
Technical field
The invention belongs to the raw melting technology of brass, be specifically related to a kind of high-strength wearable complex brass melting technology.
Background technology
Brass is most important alloy kind in copper alloy, is world-famous for, is widely used in the every field of national economy with low-cost and high-performance.But people are widely used is for a long time market brass alloy, the less of application is studied to high zinc complex brass.High zinc complex brass because of its good performance applications more and more extensive.But its production is very high to the stability requirement of technique, and its performance depends on the accurate control of various Processes and apparatus, and therefore such alloy production technical difficulty is large.
Summary of the invention
In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of high-strength wearable complex brass melting technology is provided, easy to operate.
High-strength wearable complex brass melting technology provided by the invention, adopt frequency cored induction furnace melting, alloying constituent is the Cu of Cr, 61-63% of Ni, 0.15-0.25% of Si, 0.3-0.5% of Al, 0.7-1.1% of Mn, 2.8-3.2% of 2.8-3.4%, surplus is zinc, material alloying order is for first to add 2/3Cu, add charcoal fusing, then add Si, Mn, Cr, Al, 1/3Cu, Zn successively, stir, add sodium aluminum fluoride, drag for slag and come out of the stove.
High-strength wearable complex brass melting technology provided by the invention, its beneficial effect is, based on hot-work, technical process is short, and added value is high.Ingot blank inside not easily produces the defects such as slag inclusion, loose, segregation, and internal soundness is more stable.
Embodiment
Below in conjunction with an embodiment, high-strength wearable complex brass melting technology provided by the invention is described in detail.
Embodiment
Adopt frequency cored induction furnace melting, alloying constituent is the Cu of Cr, 61-63% of Ni, 0.15-0.25% of Si, 0.3-0.5% of Al, 0.7-1.1% of Mn, 2.8-3.2% of 2.8-3.4%, surplus is zinc, material alloying order is for first to add 2/3Cu, add charcoal fusing, add Si, Mn, Cr, Al, 1/3Cu, Zn successively again, stir, add sodium aluminum fluoride, drag for slag and come out of the stove.
