Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of alloy product processing, in particular to a high-temperature master alloy bar demoulding device. Background Art
[0002] When alloy is melted and poured into the mold tube, the mother alloy is easily adhered to the steel tube and cannot be directly removed due to the influence of the pouring temperature, pouring speed, the position where the molten steel is flushed during the pouring process and the quality of the inner wall of the mold tube.
[0003] There are three main methods for demolding master alloy bars: 1. Use a tool clamp or a lifting chain to lift the undemolded steel pipe, place a metal bar with a smaller diameter than the master alloy bar in the steel pipe, and hammer it to make the master alloy bar fall off; 2. Use equipment to eject the master alloy, place the undemolded steel pipe in the equipment and press it tightly, and use a side push rod to eject the bar in the mold tube; 3. For the master alloy that has not been demolded by methods 1 or 2, use a cutting machine to cut the steel pipe and take out the bar.
[0004] The contact area between bars of different diameters and the mold tube is different, so the resistance they encounter during ejection is different. The ejector rod of the bar ejection equipment used in method 2 cannot be replaced or is difficult to replace, and the support position of the steel pipe cannot be moved up and down. For the ejection of bars of steel pipes of different diameters, the ejector rod and the steel pipe cannot be concentric, and the ejector rod often supports the steel pipe, and the ejector rod will push the steel pipe off, posing a serious safety hazard. At the same time, the process of ejecting bars requires personnel to load, eject and unload the bars, which is inefficient and labor-intensive. Utility Model Content
