CASTING PROCESS

Take you to understand the lost foam automatic production line casting workshop

The environment of the foundry workshop of the fully automatic production line of lost foam is very critical, because the demand for the process environment of lost foam is still standard, which also needs to conform to the national environmental protection policy, dust removal and less exhaust emissions, which is one of the advantages of the foundry workshop of the fully automatic production line of lost foam. The following is a specific account of the small series for everyone.

Take you to understand the coating of lost foam casting equipment.

The lost foam casting equipment coating produced by the lost foam equipment production line is a kind of refractory coating, usually composed of refractory design materials, carriers (solvents), adhesives, suspending agents, surfactants, thixotropic agents and their important components. Materials with refractory properties include corundum/silica sand/bauxite/zircon sand/kaolin clinker/diatomite/magnesia, etc. According to the study found that for the different alloy structural materials, it is necessary to make the coating of lost foam casting equipment through different refractory materials. Also of particular interest is the shape, thickness and distribution of the refractory particles.

How to Control the Electronic Control System of Lost-in-process Molding Equipment Production Line

The production line of lost-form equipment adopts programmable automatic program control, with automatic and manual switching functions. The start and stop of each unit equipment in the lost-form equipment production line can realize the following operations: Press the general start button. When the whole line is automatically powered on in sequence and meets the stop conditions, the whole line will automatically shut down. However, if a unit equipment does not meet the shutdown conditions, the equipment can continue to operate, and will be completely shut down after the conditions are met.

Selection of Lost-in-process Molding Production Line

Because the country attaches great importance to environmental protection, environmental protection will strictly control the production line of lost vanity mold, so the future of lost vanity mold production line to take the route of environmental protection. With the rapid economic development of social science and technology and cultural industries, people's demand for casting technology is increasing, and the application of lost foam casting is becoming more and more common. Due to the complex market environment, systematic screening is particularly important. Vibrating screen, lifting roller, sand bin, vibrating platform and negative pressure system constitute the lost foam casting production line.

What should be paid attention to in the process of the lost-flow mold production line

The pouring process of the lost foam production line is the process of steel liquid filling and foam mold evaporation. Throughout the process, it should be noted that: (1) The runner shall be filled with molten steel from beginning to end. If it is not met, because the coating strength is limited, it is easy to cause sand collapse and air intake, resulting in casting defects. (2) When pouring molten steel, grasp it to ensure stability, accuracy and speed. Instantly fill the pouring cup so that it flows in rapid succession, about one ton of molten steel a minute. If the molten steel of the casting in the same box is cut off, air will be sucked in, causing the sand hole to collapse or increase the porosity of the casting, resulting in the casting scrap.

Introduction of Lost Foam Casting Materials

Lost foam casting uses a variety of casting materials, of which the important ones are model materials, casting coatings and dry sand. The model material of lost foam casting is usually called beads. Casting beads are generally divided into PS-polystyrene beads and PMMA-polymethyl methacrylate beads, both of which belong to high polymer materials, and PS PMMA polymers. For ordinary low carbon steel castings, the carbon in the model material of the lost foam casting can easily cause the surface of the production casting to require carburizing, resulting in various carbon defects.

Applicability of Lost-in-process Molding Production Line

At present, the lost vanity mold production line enterprises have become an indispensable industry in the society. Its rapid development in recent years has brought a lot of convenience to automobile production and production applications of various enterprises. It fundamentally reduces the investment cost and production cost, saves the input and output time of the enterprise from all aspects, and improves the labor efficiency of the workers. Although lost foam casting is as widely used in manufacturing as other casting processes, it has its drawbacks and limitations. Not all castings are suitable for such production, according to the casting itself to analyze. We can consider whether to use this method from the following aspects:

Take you to understand the lost vanish mold production line

Compared with the traditional sand casting process, the varieties and materials of lost foam products are more diversified, especially automotive aluminum alloy parts. Now, the application of lost foam casting is more and more, and the casting quality is good and the scrap rate is low. The reference process parameters of the disappearance casting process are the amount of modifier, casting wall thickness and pouring temperature, the casting strength and elongation of ZL102 alloy are selected as the evaluation index of casting mechanical performance, and the effect of casting process parameters on casting mechanical properties is studied by combining gray correlation method and orthogonal test. According to the average gray scale of each coefficient and the range of the lost mold production line, judge the evaluation of each process parameter.
