Description

Aluminum-strontium intermediate alloy adding mechanism

Technical Field

The utility model relates to an alloy material application especially relates to an aluminium strontium intermediate alloy adds mechanism.

Background

The aluminum-strontium intermediate alloy is an excellent aluminum alloy modifier developed in recent years in China, and is mainly used for modification of hypoeutectic and eutectic aluminum-silicon alloys. The deterioration type is equivalent to that of the conventionally used sodium salt, but has a remarkable advantage compared with the sodium salt. The conventional deterioration of sodium salt has disadvantages such as wrong dosage, poor melt fluidity and toxicity, and also, since sodium element is rapidly evaporated and oxidized in the process of maintaining molten alloy, the deterioration time of sodium is short, and thus it is not suitable for continuous mass production. The aluminum-strontium master alloy overcomes the above disadvantages of sodium salt deterioration. Typically, the addition of the aluminum strontium master alloy requires manual addition by an operator into the tundish or crucible furnace.

Because strontium is very easy to be oxidized, the strontium is directly added into the alloy to cause great burning loss and is difficult to store. Therefore, the aluminum strontium intermediate alloy is added into the aluminum liquid in the conventional mode. The aluminum-strontium intermediate alloy needs to be added when the aluminum is in a complete molten state, and the early or late addition of the aluminum-strontium intermediate alloy increases the burning loss of the strontium element, so the addition time and the addition mode of the aluminum-strontium intermediate alloy are particularly important. The traditional mode is that the operator throws the aluminium strontium intermediate alloy piece to aluminium liquid by bare-handed, uses this kind of joining mode, adds the opportunity and often can not control, and degree of automation is low, and intensity of labour is big, probably causes aluminium liquid to splash when adding moreover, causes personnel to scald scheduling problem.
