Abstract
The invention discloses a kind of synchronous method of smelting producing cylinder sleeve molten iron, after melting material is divided into 15-25 part in proportion, then part melting material will do not had to carry out smelting and pouring in turn, because the melting material quantity in smelting furnace reduces, the corresponding shortening of smelting time, then melting direct cast after completing, carries out the melting of other part of melting material again after cast, shorten the time of melting, improve production efficiency.
Description
Technical field
The present invention relates to cylinder sleeve production field, specifically a kind of synchronous method of smelting producing cylinder sleeve molten iron.
Background technology
Cylinder sleeve adopts molten iron cast to form, and molten iron is that after being prepared burden by the pig iron and other components, in smelting furnace, melting forms.The method of smelting of original molten iron is that all melting materials that can be held by smelting furnace add, and then carry out adding hot smelting, after general melting 2-3 hour, melting completes discharging and pours into a mould.This mode smelting time is oversize, and production efficiency is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of synchronous method of smelting producing cylinder sleeve molten iron, carries out smelting and pouring in turn, save smelting time, improve production efficiency after melting material being carried out pro rate.
Technical scheme of the present invention is:
Produce a synchronous method of smelting for cylinder sleeve molten iron, include following steps:
(1), prepare melting material by standard before smelting furnace water outlet, the pro rate average of all melting materials is divided into 15-25 part;
(2), smelting furnace first time water outlet after, the power of smelting furnace is adjusted to 150-160KW, and the melting material then prepared by portion adds, and waits for after 2.5-3 minute, measurement molten iron temperature;
(3), when molten iron temperature is higher than the molten iron temperature scope of coming out of the stove of setting, then the rapid power by smelting furnace is adjusted to insulation power, then pour into a mould, after casting complete, second part of melting material added smelting furnace and the power of smelting furnace is adjusted to 150KW, after having fed in raw material, in the smelting furnace of 150-160KW, proceeding melting;
(4), when molten iron temperature is lower than the molten iron temperature scope of coming out of the stove of setting, then the power of smelting furnace is adjusted to insulation power after second by wait 20-40, then pour into a mould, after casting complete, second part of melting material added smelting furnace and the power of smelting furnace is adjusted to 150KW, after having fed in raw material, in the smelting furnace of 150-160KW, proceeding melting;
(5), when molten iron temperature is come out of the stove in molten iron temperature critical field what set, then by normal mileometer adjustment speed, the power of smelting furnace is adjusted to insulation power, then pour into a mould, after casting complete, second part of melting material added smelting furnace and the power of smelting furnace is adjusted to 150KW, after having fed in raw material, in the smelting furnace of 150-160KW, proceeding melting;
(6), according to the method for step (3)-(5), repeat reinforced melting and cast, until 15-25 part melting material all smelting and pouring is complete.
0.5 ton of intermediate frequency furnace selected by described smelting furnace.
Described insulation frequency is 50KW.
The described every melting of melting material also, after pouring into a mould 5-10 time, is analyzed the chemical composition of molten iron in smelting furnace, carries out ratio adjustment according to composition result to prewired melting material.
Advantage of the present invention:
After melting material distributes by the present invention, the melting material quantity in smelting furnace reduces, and the corresponding shortening of smelting time, then melting direct cast after completing, carries out the melting of other part of melting material again, shorten the time of melting, improve production efficiency after cast.
