In the die-casting and foundry industries, due to the large demand for molten aluminum, it is usually necessary to transfer the molten aluminum to a holding furnace next to the machine after centralized melting. Therefore, the molten aluminum transfer bag has become an indispensable configuration for die-casting and foundry workshops. Transfer bags come in different shapes and sizes, and their functions are also different. Today, we will discuss how to choose a suitable transfer bag.

Types and uses of transfer bags

Depending on the method of transportation, it is generally divided into forklift type, suspension (crane) type, and fork-lift dual-purpose type. According to the different sealing properties, it is divided into open type and teapot type.

Forklift

Generally, a motorized forklift (diesel or electric) is used to carry the transfer bags for transportation.

Suspension (crane) type

Generally, a crane is used to hang the transfer bag and then move it for transportation.

Fork-lift dual-purpose

This type of transfer bag is a suspended transfer bag with a forklift slot added to the bottom, which can meet the transfer needs of the above two types of equipment at the same time.

Open

Open bags are transfer bags without covers, which are usually used for short distances within the factory.

Teapot

The transfer bag is equipped with an insulation cover, and the water outlet is designed to be tubular, just like a household teapot. It is made of lightweight castables, can rotate 360° without aluminum leakage, has good insulation performance, and has a small temperature drop. It is suitable for long-distance transportation or transportation that requires long-term insulation.

Transfer bag selection

It mainly needs to be considered comprehensively from the following aspects:


1. Transport channel space in the workshop: The size of the reserved space for the aluminum liquid transfer channel directly determines the transfer method that can be used. When the space is small, only the suspension type can be selected; when the space is large, both methods can be used, but the forklift type is usually preferred. The forklift dual-purpose type is mainly suitable for enterprises with small workshop channel space and a long distance from the centralized furnace to the workshop. That is, forklifts are used for transportation between the centralized furnace and the workshop, and overhead cranes are used for transportation within the workshop.
2. Loading capacity at one time: If there are a large number of machines, a forklift is generally used because it has a large loading capacity at one time and can save transportation time.
3. Transportation distance to the workshop: If the centralized furnace or centralized insulation furnace is far away from the workshop, a forklift must be used and a cover must be added to achieve insulation.
4. Aluminum liquid temperature requirements (thermal insulation): The temperature factor is extremely important for the quality of casting products. For those companies that have strict requirements on the temperature drop range, thermal insulation must be taken into consideration, using a forklift type and adding an insulation cover.
5. Cost of use: Forklifts mainly use fuel oil (electric power is slower and less used), which is expensive to use and requires regular maintenance. Cranes rely on electricity, require less maintenance, and are relatively cheap.
6. Working speed (timeliness): The forklift type works faster, while the suspension type works slower.
7. Safety: The forklift type is stable in transportation. If it is covered, the aluminum liquid is not easy to spill. The suspension type will shake greatly during the lifting process. If it is not covered, it may spill, which may cause safety hazards such as burns.
