At present, the integral step is generally an aluminum alloy integral step. The so-called aluminum alloy integral step is a step made of aluminum alloy material by one-time die-casting. A1-Si-Cu cast aluminum alloy is the most widely used cast aluminum alloy material in the industry. These alloys have excellent casting performance, high strength and good corrosion resistance, and are widely used in many fields such as escalators, elevators, and key automotive parts. When processing elevator steps, it is first necessary to process and cast aluminum alloy ingots. When processing and casting aluminum alloy ingots, the qualified aluminum alloy mixture is mostly transferred into a melting and casting static furnace, and the aluminum alloy mixture in the static furnace is cast by semi-continuous casting.

[0033] A process for casting an aluminum alloy ingot for elevator steps comprises the following steps: Step 1: Select silicon, copper, magnesium, manganese, niobium and tantalum with a suitable mass ratio as blanks for melting, add aluminum metal materials into a high-temperature melting furnace for melting, and then put the silicon, copper, magnesium, manganese, zinc, iron and vanadium selected from the ingredients into the high-temperature melting furnace for mixed melting with metal aluminum, and then perform slag removal and exhaust work, stir and slag the melt, remove large impurities in the melt, and use a graphite rotor to degas the melt after stirring; Step 2, deslagging the mixed material, adding corresponding amounts of niobium, tantalum, thulium and lanthanum to the molten material after deslagging and exhaust, heating and smelting to obtain an aluminum alloy mixed material, stirring the aluminum alloy mixed material, deslagging for a second time, removing large impurities in the molten material, and degassing the molten material for a second time after stirring using a graphite rotor, and detecting the quality of the aluminum alloy component, sampling and analyzing in front of the furnace, detecting the component content of the alloy in the aluminum alloy mixed material, and replenishing the melt with unqualified component content to reach the qualified range, and continuously adjusting the proportion of each metal material during the smelting process to meet the predetermined requirements; Step 3, casting the qualified aluminum alloy mixture by using an ingot casting device, standing and naturally cooling to room temperature, to obtain an aluminum alloy billet; Step 4: Prepare elevator steps using the prepared aluminum alloy billet as material.

[0034] Working principle: connect the end of the liquid inlet main pipe 352 to the aluminum alloy mixture outlet, control the start of the driving motor 231, drive the corresponding guide roller 23 to rotate, thereby driving the transmission sprocket 24 to rotate, and then control the transmission chains 241 on both sides to perform stable and slow transmission, thereby driving multiple casting auxiliary parts 5 to be slowly transmitted to the position of the transmission mechanism 4 in sequence; When multiple casting auxiliary parts 5 are slowly transported, the top support rod 251 supports the casting molds 52 in the multiple casting auxiliary parts 5 at the upper position of the transmission chain 241, and the bottom support rod 261 supports the casting molds 52 in the multiple flipped casting auxiliary parts 5 at the lower position of the transmission chain 241, thereby improving the stability of the slow transport of the casting auxiliary parts 5; When one of the guide rollers 23 rotates, it cooperates with the transmission of the first pulley transmission group 6 and the meshing connection of the two transmission gears 37 to drive the rotating tube 321 to rotate in the opposite direction synchronously, thereby controlling the buffer cylinder 32 to rotate in the opposite direction, so that the transmission direction of the multiple casting molds 52 is opposite to the rotation direction of the buffer cylinder 32; When one of the guide rollers 23 rotates, it cooperates with the transmission of the second pulley transmission group 7 to drive the second transmission roller 43 to rotate synchronously, thereby controlling the transmission belt 44 to perform synchronous transmission; During casting, the aluminum alloy mixture that has passed the inspection is introduced into the liquid inlet main pipe 352 through the output port, and is introduced into the buffer cylinder 32 for buffering through the U-shaped horizontal pipe 351, the two-side connecting longitudinal pipes 341, and the liquid inlet insert 34, and is discharged into the casting mold 52 below through the drainage protrusion 33 at the bottom position. At the same time, the aluminum alloy mixture is introduced into the adjacent casting mold 52 through the drainage protrusion 33 at other positions at the bottom for liquid replenishment. Since the transmission direction of the multiple casting molds 52 is opposite to the rotation direction of the buffer cylinder 32, the aluminum alloy mixture is rotationally introduced into the multiple casting molds 52 step by step in sequence, and multiple aluminum alloy ingots are automatically and quantitatively cast, thereby improving the casting processing quality and efficiency of the aluminum alloy ingots. With the stable transmission of the casting mold 52, the aluminum alloy mixture is stably transmitted, and is left to stand and naturally cool to room temperature to obtain an aluminum alloy billet. The aluminum alloy billet is located in the casting mold 52 until the casting mold 52 is transported to the position of the transfer mechanism 3. The ball 56 in the casting auxiliary part 5 at this position first contacts the cross brace rod 271. With the transmission flipping of the casting auxiliary part 5 at the end position, the ball 56 contacts the arc auxiliary rod 272. The arc auxiliary rod 272 slowly presses against the ball 56 to drive the longitudinal push rod 54 and the top plate 55 to extend into the casting mold 52. The top plate 55 pushes the aluminum alloy billet out of the casting mold 52, and the aluminum alloy billet is automatically unloaded. The aluminum alloy billet automatically falls on the transmission belt 44 for subsequent transmission and processing of the aluminum alloy billet, further improving the processing efficiency of aluminum alloy ingots.
