Abstract

The invention discloses a process for smelting aluminum-iron bronze so as to solve the problem of rolling fracture during the production of aluminum-iron bronze at present. The process is characterized by comprising the following steps: brushing black charcoal powder on and preheating and drying an intermediate-frequency furnace before use, then adding Cu and scrap returns into the intermediate-frequency furnace at the same time to ensure that the temperature of Cu reaches 1150-1200 DEG C, pressing a preheated Al-Fe intermediate alloy into the Cu solution, stirring, and adding the preheated Al-Fe intermediate alloy so as to ensure that the Al content in the alloy is 8.5-9.2% and the Fe content is 3-4%; pressing ZnCl2 into the mixture by using a bell jar to perform dehydration, gas removal and refining. The process not only can be used for solving the problem of rolling fracture during the production of the aluminum-iron bronze, but also is simple and feasible in process flow and can directly guide production.

Description

A kind of melting technology of ampco
Technical field
The present invention relates to casting field, especially a kind of melting technology of ampco.
Background technology
The binary alloy of Cu and Al and wherein add again the multicomponent alloy of Fe, Mn or Ni to be called xantal.Xantal is the alloy that 20 beginnings of the century just began one's study, grows up, and still, because it has high corrosion resisting property and intensity and the toughness that can compare favourably with steel, thereby has obtained development rapidly, has become now application utmost point copper alloy widely.
Xantal has the performance of many excellences, and such as 1. high mechanical property, xantal not only intensity is high, and plasticity is the more than 2 times of tinbronze, quite even higher with cast steel; 2. good chemical stability, more corrosion-resistant, and especially corrosion fatigue strength is high, is difficult for corrosion cracking.Also can replace stainless steel to want valve parts; 3. compactness is high, is usually used in casting the important valve parts of working under high pressure.4. xantal cost is lower than tinbronze, and density is also little.
The situation that occurs roll extrusion fracture when the current ampco condition of production and processing, assembling, and more, the product quality of the product defects of ampco class material foundry goods was difficult to guarantee in the past.
Summary of the invention
The situation of the roll extrusion fracture occurring when solving the production of aluminum current iron bronze, the invention provides a kind of melting technology of ampco, not only can address the above problem, and simple possible, reliability is high.
The melting technology of described a kind of ampco, it is characterized in that: before intermediate frequency furnace uses, brush after black stump chalk pre-heating drying, Cu, foundry returns are packed in intermediate frequency furnace simultaneously, make Cu temperature reach 1150 ~ 1200 ℃, add preheating Al-Fe master alloy to be pressed in Cu liquid, stir, while adding preheating Al-Fe master alloy, guarantee that in alloy, Al content is 8.5% ~ 9.2%; Fe content is 3% ~ 4%; Recycling bell jar is pressed into ZnCl 2dehydration refinery by de-gassing.
The invention has the beneficial effects as follows: the situation of the roll extrusion fracture occurring during the production that not only can solve ampco, and technical process simple possible, can directly instruct production.
Embodiment
In order accurately to control casting composition, the whole process of using direct-reading spectrometer to carry out fusion process is controlled, real-time both analysis, and the chemical composition of adjustment aluminium alloy, accurately controls the Al content in alloy.
Adopt intermediate frequency furnace to carry out molten alloy liquid, new crucible is with front necessary through strict baking.The smelting furnace that other copper alloys are crossed in melting generally must not be used, and in the time of must using, will after prepurging, can use.Melting instrument can use after should brushing zinc oxide or black lead powder coating pre-heating drying before using.
Before using, brushes after black stump chalk pre-heating drying by intermediate frequency furnace, Cu, foundry returns are packed in intermediate frequency furnace simultaneously, make Cu temperature reach 1180 ℃, add preheating Al-Fe master alloy to be pressed in Cu liquid, stir, while adding preheating Al-Fe master alloy, guarantee that in alloy, Al content is 9%; Fe content is 3.5%; Recycling bell jar is pressed into ZnCl 2dehydration refinery by de-gassing.
