Casting device of zinc straight line ingot molding machine with duplex-mold

Abstract

The invention relates to a casting device of a double linkage-die zinc beeline ingot-casting machine. A zinc discharging hole is cut at the bottom of a zinc smelter. Zinc liquid is collected through a downward suspension launder and a zinc liquid distributing disk of a turntable style casting device without contact. The zinc smelter is in sealed state. The turntable style casting device drives the distributing disk on which zinc liquid casting distribution nozzles are equally arranged in a radial direction to revolve through a chain-wheel transmission device, so as to realize the synchronous operation of casting operation and ingot mold running. The invention changes liquid-collecting from a zinc liquid surface of the traditional scoop ration casting mechanism and also displaces a motor and a transmission system of the prior scoop ration casting mechanism. Therefore, the equipment structure is simplified and the equipment failure becomes less, with high reliability, reduced maintenance cost. The zinc liquid is collected in sealed state so as to reduce slag rate and enhance the product quality.

Description

technical field [0001] The invention relates to equipment for zinc melting and casting, in particular to a casting equipment for dual-mode casting of a zinc linear ingot casting machine. Background technique [0002] The casting device is a device used to cast zinc liquid into the ingot mold cavity in the zinc linear ingot casting unit. Generally, a spoon-type quantitative casting device is used (as shown in Figure 1). Spoon the zinc liquid from the liquid surface, and pour the zinc liquid from one end to the other end into the ingot mold through the rotation of the casting spoon. It starts or stops the motor operation by touching the limit switch. The casting spoon passes through the motor, decelerates The machine and the crank link mechanism realize the swing around the fulcrum of the support frame, and the swing angle is 45°. Its working process is: when the ingot mold running wheel touches the start limit, the casting spoon inserted into the zinc liquid rotates around th...

Problems solved by technology

[0003] The disadvantages of this device are: 1. The scoop-type quantitative casting device will tap the surface of the molten zinc every time it digs the molten zinc from the molten zinc furnace, causing the surface of the molten zinc to oxidize continuously, and the molten zinc in the molten zinc furnace contains a lot of slag

2. Since the casting spoon always takes the zinc liquid from the surface, the produced product contains a lot of slag and the quality declines

3. Since the spoon-type quantitative casting device is installed close to the zinc melting furnace, and the temperature of the molten zinc in the zinc melting furnace is between 450° and 550°, the spoon-type quantitative casting device has been operating in a high-temperature environment for a long time due to radiant heat, and the operation failure is relatively frequent. Many, affecting the normal production

4. This method needs to open a 500×500 hole in the zinc melting furnace to take the zinc liquid, which affects the heat preservation of the zinc melting furnace and causes an increase in energy consumption

Due to the high temperature environment and the influence of zinc liquid splashing, the start and stop limit switches and their cables are often damaged. Moreover, because the start and stop positions are required to be more accurate, the limit switches are often adjusted, and human factors are more important. Large impact, the setting and adjustment of the limit requires more skilled technology

2. Damage to the motor and reducer

Due to the operation of the motor and the reducer in a high-temperature environment, the failure rate is high, especially the reducer, which causes poor lubrication due to operation at high temperature, and often causes the reducer to be stuck and the reducer base to crack

3. There are many faults in the crank connecting rod mechanism

The crank and the connecting rod are connected by a screw, the screw is often damaged, and the bearing of the crank is also often damaged
