Embodiment Construction

[0018] A synchronous smelting method for producing molten iron for cylinder liners, comprising the following steps:

[0019] (1) Prepare the smelting materials according to the standard before the 0.5-ton intermediate frequency furnace is discharged, and divide all the smelting materials into 20 parts in proportion;

[0020] (2) After the first water discharge from the 0.5-ton intermediate frequency furnace, adjust the power of the 0.5-ton intermediate frequency furnace to 150-160KW, then add a portion of the prepared smelting material, wait for 2.5-3 minutes, and measure the temperature of the molten iron;

[0021] (3) When the temperature of the molten iron is higher than the set temperature range of the molten iron, quickly adjust the power of the 0.5-ton intermediate frequency furnace to 50KW, and then pour. After the pouring is completed, add the second smelting material to the 0.5-ton intermediate frequency furnace and Adjust the power of the 0.5-ton intermediate frequen...

Abstract

The invention discloses a synchronous smelting method of molten iron for producing cylinder liners. A smelting material is divided into 15-25 parts according to proportion; each part of the smelting material is smelted and cast in sequence; since the amount of smelting material in a smelting furnace is lowered, accordingly, the smelting time is shortened, casting is directly performed after the smelting, then the smelting of other parts of the smelting material is performed, the smelting time is shortened, and the production efficiency is improved.

Description

[0001] technical field [0002] The invention relates to the field of cylinder liner production, in particular to a synchronous smelting method for producing molten iron for cylinder liners. Background technique [0003] The cylinder liners are poured from molten iron, which is smelted in a smelting furnace after being dosed with pig iron and other components. The original molten iron smelting method is to add all the smelting materials that the smelting furnace can accommodate, and then heat and smelt. Generally, after 2-3 hours of smelting, the smelting is completed and the material is discharged and poured. The smelting time of this mode is too long, and the production efficiency is low. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a synchronous smelting method for producing molten iron for cylinder liners. The smelting materials are distributed in proportion and then smelted and poured sequentially, w...
