Embodiment 1

[0027] Refer to attached figure 1 , 2 , the nickel-chromium alloy aluminum water distributor with upper and lower reinforcing rings of the present invention has the same shape and body structure as the existing aluminum water distributor, including a distributor body 4, and the distributor body is surrounded by aluminum nozzles 3 at equal intervals on the circumference, A distributor bushing 5 is arranged in the middle of the distributor body, and an upper reinforcement ring 1 and a lower reinforcement ring 2 are respectively assembled and welded around the distributor body at the upper and lower parts of the aluminum nozzle of the distributor body.

[0028] The manufacturing process adopted: model making—paint preparation—hanging sand—packing—melting and pouring—welding reinforcement rings.

[0029] 1. Make a model: use polystyrene (EPS). According to the blueprint of the aluminum water distributor, it is molded with a molding machine, and the shrinkage of the model is 2%. ...

Embodiment 2

[0042]Manufacturing process is the same as embodiment 1, and the proportioning of 450Kg charge is: carbon content is 0.15wt% high-quality low-carbon steel: 172Kg, FeCr58CO.21 ferrochrome add-on is 209Kg, FeCr58C7.5 ferrochrome add-on is 11Kg. 28Kg of nickel is added in the form of pure nickel, 6.5Kg of FeMo70, 5.5Kg of FeNb60, 9.5Kg of FeTi30, 3Kg of FeSi60, and 5.5Kg of FeMn65.

[0043] Laboratory analysis: chemical composition (weight percent): C: 0.35, Cr: 27, Ni: 6, Mo: 1, Nb: 0.7, Ti: 0.6, Si: 0.4, Mn: 0.7, the balance is Fe and unavoidable Impurities.

[0044] The assembly and welding of the stainless steel round steel reinforcement ring is the same as in Example 1.

Abstract

The invention relates to a nickel-chromium alloy aluminum-water distributor with upper and lower fastening rings. The aluminum-water distributor comprises a distributor body and is characterized in that the distributor body is formed by integrally casting alloy materials in percentage by weight: 0.25-0.45% of carbon (C), 24-30% of chromium (Cr), 4.50-7.50% of nickel (NT), 0.30-0.60% of silicon (Si), 0.50-0.80% of manganese (Mn), 0.8-1.2% of molybdenum (Mo), 0.4-0.7% of titanium (Ti), 0.5-0.8% of niobium (Nb), equal to or less than 0.04% of sulfur (S), equal to or less than 0.04% of phosphorus (Ph), and the balance being iron (Fe). One stainless steel round bar fastening ring is welded at the upper part and the lower part of an aluminum outlet of the distributor body respectively by surrounding the distributor body. The aluminum-water distributor has the advantages that when the distributor is operated at a high temperature, components are difficult to deform and has high intensity; and the stainless steel round bar fastening rings are arranged to protect the distributor against external force, so that the distributor is difficult to break. Compared with the aluminum-water distributor made of stainless steel, the aluminum-water distributor provided by the invention has the advantages that the service life is prolonged by 10-20 times; and compared with the ordinary aluminum-water distributor made of heat-resistant alloy steel, the aluminum-water distributor provided by the invention has the advantages that the service life is prolonged by 2-3 times.

Description

1. Technical field: [0001] The invention relates to a nickel-chromium alloy aluminum water distributor with upper and lower reinforcing rings, belonging to the technical field of metallurgy. 2. Technical background: [0002] The aluminum water distributor operates at high temperature and is the heart of the casting machine in the electrolytic aluminum industry. Most of the currently used distributors are made of general stainless steel casting or heat-resistant alloy steel casting. This distributor can also be used for the old equipment 9t / h casting line and 16t / h casting line. However, with the large demand for aluminum ingots in the market, aluminum companies eliminated outdated production lines and adopted advanced technologies. Improvement to 20t / h casting line and 25t / h casting line. When the new production line is running 24 hours a day, the resistance strength of the aluminum water dispenser is required to be greatly increased. In this way, the original dispenser ...
