Note:
(1) GW - means medium frequency induction furnace, - 1 - means induction furnace capacity of 1 ton, - 500 - means furnace rated power of 500 KW, / 1 - means furnace operating frequency of 1000 Hz, / 0.5 - means melting furnace frequency of 500 Hz, - J - means hydraulic tilting furnace (furnace shell is steel shell), - JJ - means mechanical tilting furnace. (the shell of the furnace is aluminum alloy).

(2) The above quoted price is for routine configuration. Other configurations can be added, such as leak alarm, water temperature alarm, furnace switch, cover mechanism, lining ejector and transformer, cooling device (open and close cooling tower, closed cooling tower, plate heat exchanger)

3) If necessary, send technicians to carry out the commissioning: the domestic section is free; the overseas section travel expenses, accommodation and food are borne by the user and each person is subsidized 150 US dollars per day.

4) I quote EX-W at a price including simple packing, including shipping charges to Shanghai port area and all inland charges in China.

V) The above electric furnace voltage levels are 380V, 690V and 950/1000V, and the frequency is 50HZ. If the user equipment requirements are different from the above voltage levels and frequencies, each item needs to be increased by 15000USD.
