Abstract

The invention discloses an automobile engine cylinder cover casting material, which is prepared from the following ingredients (by weight): 2.32-2.35% of carbon, 1.2-1.4% of silicon, 0.32-0.68% of manganese, 0.01-0.03% of titanium, 0.10-0.30% of aluminium, 0.22-0.28% of chromium, 0.22-0.28% of vanadium, 0.12-0.14% of molybdenum, 0.02-0.05% of tin, 0.012-0.014% of cerium, sulfur being less than or equal to 0.001%, phosphor being less than or equal to 0.004%, and the rest of iron. Mechanical properties of the automobile engine cylinder cover casting material are effectively improved. The cost is low, and the efficiency is high.

Description

technical field [0001] The invention relates to the field of automobile castings, in particular to a casting material for an automobile engine cylinder head. Background technique [0002] The engine is the core equipment of the car, which needs compact structure and high power. It is the power source of the car, which not only affects the overall performance of the car, but also plays a role in guaranteeing the safety performance of the car. With the rapid development of my country's logistics and transportation industries, automobiles are developing towards high speed and high performance. In order to ensure the safety performance requirements of automobiles, higher performance requirements are put forward for the materials of the engine cylinder head. [0003] At the same time, with the increase of the load and speed of the automobile, the materials required for the cylinder head of the automobile engine should be developed to have high strength, high thermal fatigue resis...
