Problems solved by technology

[0002] As the whole society attaches great importance to environmental protection, engines are developing towards high power and small volume, and the requirements for cylinder liners, an important part of automobile engines, are getting higher and higher. The metallographic and physical and chemical indicators of ordinary low-alloy cylinder liners cannot meet the requirements for use. The metallographic structure and mechanical properties of the cylinder liner with bainite structure can meet the requirements of high strength, but in order to obtain the bainite structure in the casting process, it is necessary to add precious alloy elements such as Ni and Mo in the smelting process, raw materials cost a lot

Embodiment Construction

[0007] Use an intermediate frequency electric furnace to distribute ingredients (%) according to the following chemical composition: C: 2.8-3.0, Si: 1.8-2.2, Mn: 0.4-0.6, P<0.1, S<0.1, Cu: 1.7, Mo: 0.4-0.6, Ni : 0.2, the rest is Fe. Slowly raise the temperature to about 1400°C, take samples for analysis, and after the chemical composition is adjusted to pass, the temperature of the molten iron in the electric furnace is quickly raised to 1570-1600°C, and the conventional incubation is started. After the incubation is completed, the temperature in the casting crucible is guaranteed to be 1440-1460 Casting is carried out in the range of ℃, the temperature of the casting mold is cooled to about 1150 ℃, water cooling is implemented, and the cooling is stopped when the temperature of the casting blank is 700 ℃, and the blank is released from the mold.

Abstract

Provided are a cylinder sleeve material for an abrasion-resistant automobile and a blank molding method. The technical schemes of the high-performance low-alloy cast-iron cylinder sleeve material and casting process include that the content of copper (Cu) in chemical content of a cylinder sleeve is increased to 1.7%, the Cu replaces partial alloy of nickel (Ni) and molybdenum (Mo) and is melted at a high temperature, a beltian body under a casting state is formed, and requirements of high mechanical performance of the cylinder sleeve are met.

Description

Technical field [0001] The invention relates to a high-strength cylinder liner casting forming production process. Background technique [0002] As the whole society attaches great importance to environmental protection, the engine is developing towards high power and small volume, and the requirements for the cylinder liner, an important part of the automobile engine, are getting higher and higher. The metallographic and physical and chemical indicators of ordinary low-alloy cylinder liners cannot meet the use requirements. The metallographic structure and mechanical properties of the cylinder liner with bainite structure can meet the requirements of high strength, but in order to obtain the bainite structure in the casting process, precious alloy elements such as Ni and Mo need to be added in the smelting process, raw materials The cost is huge. Contents of the invention [0003] In order to improve the mechanical performance of the automobile cylinder liner and reduce ...
