Description

Electric control drain plug device and smelting furnace

Technical Field

The utility model belongs to the technical field of electric control, concretely relates to electric control drain end cap device and smelting furnace.

Background

In the prior aluminum alloy industry, when aluminum alloy liquid is discharged from an aluminum alloy melting furnace and cast into aluminum ingots, two water discharging modes are provided, wherein one mode is to manually open a plug of a water discharging opening of the melting furnace, and then manually adjust the opening of the plug according to the ingot casting speed so as to control the speed of the aluminum alloy liquid flowing out of the melting furnace. The opening degree of the water discharge port plug is difficult to control finely by manual regulation, or the water discharge port plug is too large, the outflow speed of aluminum water is too fast, or the water discharge port plug is too small, the outflow speed of the aluminum water is too slow, an operator needs to control the speed of the ingot casting machine, and needs to regulate the opening degree of the water discharge port plug, the aluminum alloy melt overflow and outflow outside can not be connected at times, the opening degree is too large, and the speed of the ingot casting machine is not fast enough, the temperature of the aluminum alloy melt is as high as seven hundred degrees, and accidents are easily caused. The drain plug is manually controlled, and high-temperature aluminum alloy melt can gush out when the plug is not well controlled, so that scalding safety accidents are easy to happen. The other is cylinder control, and the cylinder control has the defect that the water outlet speed of the discharged eye melt cannot be controlled in a completely opened or completely closed state. The aluminum liquid direct supply device is only suitable for the aluminum liquid direct supply industry, because the aluminum liquid direct supply industry directly puts the aluminum liquid in the furnace into a transfer bag, the water discharging speed is very high, the plug of the water discharging hole is completely opened, and when the aluminum liquid is put into an aluminum alloy ingot, the water discharging speed of the water discharging hole has very high requirements, the ingot casting speed cannot follow up quickly, so that the high-temperature aluminum liquid overflows to cause safety accidents, and the production efficiency is seriously influenced too slowly. The cylinder is influenced by the atmospheric pressure, if there is the melt in the stove in the process of smelting, the compressed air station breaks down this moment, leads to the atmospheric pressure low or no compressed air, and the end cap can become flexible voluntarily at this moment, leads to the risk that high temperature melt is leaked.

Therefore, a device which can be remotely and accurately controlled and can directly and remotely and finely control the opening degree of the drain plug according to the water draining speed of the ingot casting machine is needed to reduce the risk.
