Horizontal alloy ingot preheating charging machine

Abstract

The invention relates to a horizontal alloy ingot preheating charging machine which is formed by a speed reducer, a bearing seat, a driving screw, a pushing plate, a screw guide sleeve, a heat preserving cover, a radiation heating device, a rack and a guide rail; the working method is as follows: an alloy ingot is put onto a horizontal guide rail outside the heat preservation cover in a manual ormechanical way, the speed reducers works to drive the driving screw mounted on the bearing seat to rotate clockwise, so as to push the pushing plate in threaded connection with the driving screw to more forwards, the pushing plate moves forwards to push the alloy ingot put onto the horizontal guide rail to move towards the direction of the heat preservation cover and enter the heat preservation cover in sequence, the alloy ingot is heated to set preheating temperature by the radiation heating device in the heat preservation cover until the alloy ingot is pushed out of the heat preservation cover and slides to a designated spot along a slope at the front end of the guide rail, and the radiation heating device mounted in the heat preservation cover heats the alloy ingot during the movement of the alloy ingot. The charging machine is simple and durable, compact in structure and suitable for charging of alloy ingots for a relatively low alloy melting furnace.

Description

technical field [0001] The invention relates to a device for providing alloy ingot preheating and automatic feeding for an alloy smelting furnace in the casting field, especially high-pressure casting, squeeze casting, gravity casting and tilting casting of magnesium and aluminum alloys, belonging to light alloy casting smelting field. Background technique [0002] During the casting process, the alloy ingot first needs to be added to the melting furnace manually or automatically, and then poured after being melted in the melting furnace and kept warm to a certain temperature. During this process, the alloy ingot may be damp due to transportation or storage. If the furnace is not preheated to remove water vapor, the water vapor can easily react with the high-temperature molten metal in the furnace to generate hydrogen gas, resulting in an explosion and a safety accident. Therefore, the alloy ingot needs to be preheated to a certain temperature to remove water vapor before b...
