When the foundry purchases a steel melting furnace , there are many manufacturers who are not satisfied with the use process after buying. Today's electric furnace manufacturers already have a lot of product specifications, and the price is very different. Also let the new manufacturers do not know how to choose, here are a few references.

A, the principle of furnace selection

1 , considering the yield of each month . And the future development of the tonnage election .

2 , consider the single weight of the casting . Small castings do not have a large tonnage furnace

3 , consider the transformer monthly fee

4 , whether the electric stove saves electricity when using

5 , transformer output voltage Currently available in China, 380V , 660V , 750V , 1000V and other models have KGPS IF power supply , 12- pulse intermediate frequency power supply , 24 pulse IF power supply .

B, classification of steel melting furnace

1 , according to the supply voltage divided:

1 high-voltage furnace, with 12- pulse intermediate frequency power supply , 24 pulse intermediate frequency power supply above 660V , features fast power saving

2 ordinary furnace, with KGPS intermediate frequency power supply 380V power supply, features: high electricity costs

2 , other classification: 1 KGPS , features: commonly used have good or bad

             2 IGBT , features: high price, good power and bad technology, immature technology

3 , a belt Binary: ① a belt two parallel features: low price, high electricity

               ② a band two series, features: high price, low power

4  according to the furnace shell points : 1 aluminum shell furnace .      Features more faults

                2 steel shell furnace features less failure

C, the transformer power of the steel melting furnace tonnage
