Description
Technical field
The present invention relates to aluminum alloy melt casting equipment technical field, more particularly to a kind of crystallizer wiper.
Background technology
Semicontinuous ingot casting is that one kind makes molten metal continually by crystallizer, the ingot blank life realized solidification and crystallization and be molded
Production. art, in casting process, metal bath is equably imported in the crystallizer that outer wall is water-cooled, in crystallizer wall and knot
Quick solidification crystallizes under the collective effect of brilliant device base, and forms a firmer solidified shell, metal bath in device to be crystallized
Horizontal liquid level when reaching a certain height, the haulage gear of casting machine just drives base and the solidified shell being set on base one
Rise and continuously, equably moved down with certain speed, the part for being frozen into ingot casting for being separated from crystallizer is immediately exposed to come from
The direct cooling of the secondary cooling water of crystallizer lower edge, the crystallizing layer of ingot casting also continuously promote to central area and complete therewith
Full solidification and crystallization.After extrusion ingot length reaches given size, stopping casting, unload ingot casting, casting machine base returns to home position,
Complete a casting time.
But because the cold plasticity of the big size ingot-casting of some alloys is poor, if ingot casting leaves crystallizer
Directly cooled down by secondary cooling water, ingot casting axial temperature difference can be caused to increase, cold cracking inclination occur, influence ingot quality, therefore,
, it is necessary to install crystallizer wiper, the master of crystallizer wiper in crystallizer lower edge when casting the alloy of this type
It is a ring-shaped rubber piece to want part, and the ring-shaped rubber piece is located at the lower section of crystallizer lower edge, and its internal diameter is less than the diameter of ingot casting, when
When ingot casting moves down, rubber inward flange downwardly turns over and holds ingot casting tightly so that the part below the bottom of liquid cave on ingot casting
Water cooling is no longer received, it is poor so as to reach reduction ingot casting axial temperature, reduce the purpose of cold cracking inclination.
At present, rubber peel typically has two kinds used in crystallizer wiper：First, import rubber peel, Wear-resistant, high-temperature resistant
Better performances, but it is expensive, and use cost is high；Another kind is home rubber skin, and Wear-resistant, high-temperature resistant poor performance is, it is necessary to frequently
Carry out change, cause crystallizer wiper service life short, influence being normally carried out for production, and easily unsuccessfully made because scraping water
Ftractureed into ingot casting, cause scrap rate to rise, production cost increase.
Therefore, how a kind of crystallizer wiper is provided, makes its simple in construction, is easy to safeguard and can have longer
Service life, reduce and change number and use cost, turn into those skilled in the art's important technological problems urgently to be resolved hurrily.
