Trolley furnace are only necessary in certain situations. When choosing a furnace, the first consideration is the furnace type. The basic principles of trolley furnaces: For fixed-volume production of products, consider continuous furnaces or rotary hearth furnaces for their high productivity and thermal efficiency.
For non-specialized forging shops without furnaces, the frequent changes in product type and billet size will lead to fluctuating productivity of the forging equipment, requiring heating equipment to adapt accordingly. Furnaces offer greater flexibility. For shops producing single pieces or small batches, or with frequent changes in product types, chamber furnaces should be considered.
The fuel type used in trolley furnaces should comply with national energy policies and be based on local materials whenever possible. If there are specific requirements for heating quality and productivity, the fuel type should be considered. For example, if you want to use a rotary hearth furnace for batch heating, you cannot use coal. The type of metal to be heated varies depending on the metal and the heating process.
It is suitable for non-ferrous metals, their alloys, heat-resistant steels, etc. Flame furnaces are generally not used, but electric heating should be considered. For alloy steels, double-chamber furnaces are used when preheating is required. If it is relatively large, a semi-continuous push-in furnace can be used. For large ingots (over 1 ton) or workpieces with large sizes, an industrial furnace trolley furnace can be considered for ease of loading and unloading. Therefore, it is necessary to select the appropriate trolley furnace type according to the type of metal to be heated.
