Embodiment Construction

[0017] A synchronous smelting method for producing molten iron for cylinder liners includes the following steps:

[0018] (1) Before the water is discharged from the 0.5 ton intermediate frequency furnace, the smelting materials are prepared according to the standard, and all the smelting materials are divided into 20 parts according to the proportion;

[0019] (2) After the 0.5 ton intermediate frequency furnace is discharged for the first time, adjust the power of the 0.5 ton intermediate frequency furnace to 150-160KW, then add a portion of the prepared smelting materials, wait for 2.5-3 minutes, and then measure the temperature of the molten iron;

[0020] (3) When the molten iron temperature is higher than the set temperature range of the molten iron from the furnace, the power of the 0.5 ton intermediate frequency furnace is quickly adjusted to 50 kW, and then pouring is performed. After pouring is completed, the second smelting material is added to the 0.5 ton intermediate freq...

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

Technical field [0001] 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 [0002] The cylinder liner is made by pouring molten iron, and the molten iron is smelted in a smelting furnace after batching pig iron and other components. The original molten iron smelting method is to add all the smelting materials that the smelting furnace can hold, and then heat and smelt. Generally, after smelting for 2-3 hours, the smelting is completed and the material is discharged and poured. The melting time in this way is too long and the production efficiency is low. Summary of the invention [0003] 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 proportionally distributed and then smelted and poured sequentially, which saves smeltin...
