A control device for laboratory alloy melting

Abstract

The invention discloses a control device for laboratory alloy smelting. The device comprises a bell jar, a stirring module, a thermocouple, a rotating motor, a lifting platform and a digital display,wherein the bell jar comprises a first half-split bell jar and a second half-split bell jar, wherein one side of the first half-split bell jar is connected with one side of the second half-split belljar through a connecting bolt, the connecting bolt is used for fixing one end of a vertical lifting rod, and the other side of the first half-split bell jar and the other side of the second half-splitbell jar are fixedly provided with a clamping buckle for controlling opening or closing; the stirring module comprises stirring blades, blade connecting rods, a hollow flat plate, a fixing rod and ahollow middle shaft connecting rod, one end of each stirring blade is connected with each angle of the lower surface of the hollow flat plate through each blade connecting rod, and each angle of the upper surface of the hollow flat plate is connected with the middle shaft connecting rod through a fixing rod. According to the device, the three devices of a temperature measurement device, a bell jardevice and a stirring device are combined into a whole, so that the operation is more convenient, and the control device is more suitable for single-person or double-person work, the number of an operator and the workload are reduced, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of alloy melting, in particular to a laboratory alloy melting control device. Background technique [0002] During the alloy melting process in the laboratory, some alloying elements and additives need to be added to obtain an alloy with a certain composition and performance. However, the density of some alloys and additives added is less than the density of the melt, and they tend to float on the surface of the melt. Therefore, it is necessary to use a bell jar to press them into the melt to make them fully contact with the melt, or diffuse, or react. In turn, waste of materials is avoided. After alloying elements are added, the melt needs to be stirred to ensure uniform diffusion of the alloying elements, thereby obtaining a material with uniform composition. At the same time, it is necessary to measure the temperature of the melt in real time to observe the temperature change when the alloy elements are adde...

Problems solved by technology

[0003] However, in the current smelting process in the laboratory, the bell jar, stirring device and thermocouple are all separated independently, and it is difficult to realize feeding, stirring, and temperature measurement at the same time, especially when magnesium alloy smelting needs to be fed with protective gas. It is difficult for one operator to take care of all the processes of ventilation, feeding, stirring and temperature measurement, and two operators may even be in a hurry

At the same time, at present, stirring in the smelting process in the laboratory often requires opening the furnace cover. Even if the furnace cover has been modified to a certain extent, it is often necessary to open the furnace cover in order to stir evenly, and it is difficult to separate the thermocouple and stirring rod. placed in the melt

Frequent opening of the furnace door leads to a decrease in the temperature in the furnace, which is not only time-consuming and labor-intensive, but also a waste of resources. In addition, for some systems where chemical reactions occur during the smelting process, such as in-situ synthesis, the temperature drop caused by opening the furnace door is of great importance The measurement of endothermic or exothermic during the reaction will also affect

At present, the existing bell jars, stirring devices and thermocouples are unable to meet the complex melting process of simple operation by one person
