Embodiment Construction
[0014] In the embodiment, the zinc-based alloy whose brand is RZnAl0.8Sb0.03 is taken as an example.
[0015] It is known that the manufacturer requires the chemical composition range of the brand RZnAl0.8Sb0.03 zinc-based alloy:
[0016]
[0017] The configuration method is as follows:
[0018] 1. The total weight of the last batch of products is 10.055 tons. Then, the calculation of the newly added aluminum amount is: 10.055×1000×0.8%=80.44kg. Calculation of newly added antimony amount: 10.055×1000×0.03%=3.02kg;
[0019] 2. Put the weighed antimony and aluminum materials together around the edge of the furnace to preheat;
[0020] 3. Inject the zinc liquid from the zinc melting furnace into the batching furnace. When it reaches the height of the liquid level line, it will stop automatically, and the voltage will be raised to the third gear one by one. The liquid level line here is a constant height, which is 250mm below the edge of the furnace. , when the zinc liquid i...

The invention relates to a batching method for a zinc-based alloy. The method particularly comprises the following steps of: during continuous production, returning data after metering the weight of the output products of the previous furnace; based on the return data, calculating the weight of various additive metals according to the proportion of the additive metals required by an order; weighing the various additive metals respectively; pouring mother liquor, namely zinc liquid into a batching furnace from a material-melting furnace to a liquid level line; adding the required additive metals according to a furnace material rule to prepare the zinc-based alloy of the furnace; and assaying, casting, metering and returning metering data. In the method, conception opposite to the conventional operation is adopted and two-time level-measuring operation is omitted by utilizing the previous production data result, so operation danger is reduced and measurement error is avoided; and the calculation is based on the zinc-based alloy, but not the mother liquor, so the precision of the product metering data is higher, in particular to multi-element alloy batching. Practice has proved that the one-time batching qualification rate of the zinc-based alloy is increased from 70 to 80 percent to over 98 percent. In the method, the fluctuation range of main elements is small and the stabilityof the main elements is high.
Description
technical field [0001] The invention relates to a method for batching non-ferrous metal alloys, in particular to a method for batching zinc-based alloys. Background technique [0002] In the actual production of zinc-based alloys, the batching process plays a decisive role in product quality. The existing zinc-based alloy batching method has always been the method of measuring the furnace surface liquid level: measure the furnace surface liquid level twice (after pouring and filling), and calculate the volume of the added mother liquor—→add the weight of the mother liquor—→according to the proportion Calculate the added metal weight. This technology requires the operator to repeatedly measure the liquid level on the furnace surface, which is very dangerous. In addition, the structure of the furnace body is complicated, and the measurement error of the dynamic change of the thickness of the slagging on the furnace wall is large. Moreover, in the actual production process, th...
