Abstract
The invention discloses a Kamaz heavy truck cylinder liner smelting and forming casting process. The process adopts a scheme comprising large medium frequency furnace molten iron, and large frequency furnace quenching and tempering, and thermal insulation; the temperature of molten iron is high, and is controlled at 1530-1550 DEG C; and inner quality of the molten iron is good. The process provided by the invention has the advantages that: the product yield is high, and casting quality is good. Molten iron dose in forming centrifugal casting is low, molten iron utilization rate is high, and molten iron cost is low. The process is safe and reliable. With the process, the service life of cylinder liner is long.
Description
Technical field
The present invention relates to a kind of pouring technology, be specifically related to a kind of Ka Masi and heavily block automobile cylinder liner melting and shaping pouring technology.
Background technology
The manufacturing that Ka Masi heavily blocks automobile cylinder liner requires quite strict, and this engine is former in USSR (Union of Soviet Socialist Republics), and its engine power is large, and the carrying tonnage is more than 60 tons, and the cylinder sleeve of engine needs import.The all technical of cylinder sleeve requires relatively harsher, and especially the inner quality of cylinder sleeve requires high especially.
China makes rapid progress aspect smelting technique at present, reached international advanced smelting technique level, progressively be transitioned into cupola furnace from single cupola melting---the electric furnace double melting, the superseded cupola melting of now existing partial cylinders cover manufacturers, adopt large-scale intermediate frequency furnace melt iron, large-scale main frequency furnace is modified, insulation.The Melting Quality of molten iron has reached the advanced level of developed country.But its placingJi Shu speed of development is unhappy, still on the level of the nineties in last century, on the larger impact of performance existence of cylinder sleeve.
Summary of the invention
The object of the invention is to: provide a kind of Ka Masi heavily to block automobile cylinder liner melting and shaping pouring technology, utilize Ka Masi of the present invention heavily to block the automobile cylinder liner melting and the shaping pouring technology is made the automobile engine cylinder cover, its metallographic structure is good, tensile strength is high, wear resistance is strong, the cylinder sleeve long service life, the superiority such as safety coefficient height.
The technical scheme that the technical problem that the present invention solves adopts is: 1. adopted large-scale intermediate frequency furnace melt iron, large-scale main frequency furnace is modified, the scheme of insulation.The molten iron temperature of melting is high, and inner quality is good, and molten iron temperature is controlled between 1530 ℃-1550 ℃, and the molten iron inner quality is good.
The effect that the present invention is useful is: the yield rate of product is high, and casting quality is good, and the consumption of shaping centrifugal casting molten iron is few, utilization ratio is high, cost is low, and is safe and reliable, the advantages such as cylinder sleeve long service life.
Embodiment
The iron charge and the alloying element that configure are put into melting in the intermediate frequency furnace stove, treat that molten iron temperature is raised between 1530-1550 ℃, use the spectroscopic analysis chemical composition, the qualified rear converter of composition breeds, is incubated in main frequency furnace; The teeming temperature of molten iron is 1400-1330 ℃; Pouring speed is 10 Kilograms Per Seconds, after cylinder sleeve solidifies fully, hangs mould special-purpose local together with cylinder liner blank with crane.Repeat above-mentioned action and finish the cast of next circulation.The effect that the present invention is useful is: the yield rate of product is high, and casting quality is good, and the consumption of shaping centrifugal casting molten iron is few, utilization ratio is high, cost is low, and is safe and reliable, the advantages such as cylinder sleeve long service life.
Claims (1)
1. the invention provides a kind of Ka Masi and heavily block automobile cylinder liner melting and shaping pouring technology, it is characterized in that: adopted large-scale intermediate frequency furnace melt iron, large-scale main frequency furnace is modified, the scheme of insulation; The molten iron temperature of melting is high, and molten iron temperature is controlled between 1530 ℃-1550 ℃, and the molten iron inner quality is good.
