Description

Technical Field

[0001] This utility model relates to the field of metallurgical shell-making line technology, specifically a double-line, double-station metallurgical shell-making line. Background Technology

[0002] Metallurgical shell casting is a key process in precision casting (especially investment casting, also known as the "lost-wax casting" method). It refers to the process of forming a shell with certain strength and high-temperature resistance by wrapping refractory material layer by layer on the surface of a wax pattern, which is then used for pouring molten metal. The principle is to utilize the high-temperature stability of refractory materials to form a hollow shell cavity after the wax pattern is removed, allowing the molten metal to fill and obtain a high-precision casting.

[0003] Existing metallurgical shell making is generally a single-line, single-station process, which has relatively poor efficiency. Therefore, we propose a double-line, double-station metallurgical shell making line. Utility Model Content

[0004] The purpose of this invention is to provide a dual-line, dual-station metallurgical shell-making line to solve the problems in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dual-line, dual-station metallurgical shell-making line, comprising a support base, a protective cover installed on the support base, multiple sand-spraying and drying components installed inside the protective cover, multiple second drying mechanisms installed inside the support base, a sizing mechanism installed inside the support base, and a first conveyor line installed outside the protective cover.

[0006] Preferably, the sand-spraying and drying assembly consists of a support frame, a first drying mechanism, and a sand-spraying mechanism, wherein the first drying mechanism and the sand-spraying mechanism are mounted on the support frame.

[0007] Preferably, the second conveyor line is a double-layer conveyor line, and the first conveyor line is an inclined conveyor line.

[0008] Compared with existing technologies, the advantages of this invention are: It integrates an automatic shell-making line (dual-line, dual-station) with independent operating areas (automatic sizing and sand application at each station) and independent constant temperature and humidity drying. The process is relatively simple, the control range of operating parameters is wide, and the technical requirements for operators are low, making it easy to master and operate. The drying time of the fast-drying silica sol is significantly shortened, allowing for more production batches to be completed within the same timeframe, significantly improving production efficiency. Rapid drying enables subsequent processes to be carried out promptly, making the entire production process more compact and better suited to the needs of large-scale production and rapid delivery. The fast-drying process can complete drying quickly at lower temperatures, reducing energy consumption and lowering energy costs. Rapid drying allows production equipment to be released more quickly for the next batch of production, improving equipment utilization and thus reducing the depreciation cost per unit product. The fast-drying silica sol does not produce volatile organic compounds during production, making it an environmentally friendly binder that meets the environmental requirements of modern industry. Wastewater treatment for silica sol is relatively simple and has a small impact on the environment, reducing wastewater treatment costs and environmental pressure. By optimizing formulations and processes, fast-drying silica sol can produce high-strength and high-toughness composite materials, better meeting the requirements of complex working conditions. During rapid drying, the composite material exhibits more uniform shrinkage and better dimensional stability, ensuring product precision and quality and improving product yield. Rapid drying reduces equipment downtime, wear, maintenance costs, and repair frequency. The superior performance of the silica sol composite fast-drying process and equipment makes it widely applicable in investment casting, ceramic manufacturing, electronic packaging, and other fields, offering significant advantages, especially in applications requiring rapid production and high-quality products.

Rapid drying allows for timely subsequent processes, making the entire production flow more compact and better suited to the demands of large-scale production and rapid delivery. The rapid drying process completes drying quickly at lower temperatures, reducing energy consumption and costs. Rapid drying also allows production equipment to be used for the next batch more quickly, improving equipment utilization and reducing depreciation costs per unit product. Rapid-drying silica sol does not produce volatile organic compounds during production, making it an environmentally friendly binder that meets modern industrial environmental requirements. Wastewater treatment for silica sol is relatively simple and has minimal environmental impact, reducing wastewater treatment costs and environmental pressure.
