Differences between single billet preheating and multi billet preheating

1. Structure of furnace body
Single billet preheating furnace only allows one aluminum billet to be heated in the furnace at a time, while the multi billet preheating furnace allows multiple billet to be preheated inside the furnace.

2. Heating mode
The single billet preheating adopts gas blowout for billet preheating, while the multi billet preheating uses heated air circulation for heat.

Single billet preheating furnace

Advantages
1. Temperature of the aluminum billets can be controlled by the operators;
2. The preheating furnace is available in a quick temperature rise;
3. There is no limitation on the length of the aluminum billets.

Weakness
The aluminum billet is likely to have uneven temperature after being heated, so the heating furnace used must be available in a uniform effect on the heated billets.

Multi billet preheating furnace

Advantages
1. The preheating furnace features long preheating time, but is available for uniform heating effect;
2. The preheating furnace has a better temperature preservation effect.

Weakness
1. There are limitations on the length of the aluminum billets, which depends on the length of the heating furnace;
2. The furnace covers a large area.

The single billet and multi billet preheating furnace feature their own advantages and weaknesses, so, while providing customers with aluminum extrusion auxiliary equipment, we will take the specific workshop of the manufacturer of aluminum extrusion profiles into full consideration or give optimum recommendation to the customers to ensure that the auxiliary equipment meet specific needs of the customers and take advantages of our aluminum extrusion auxiliary equipment.
