Embodiment Construction
[0013] A high wear-resistant alloy steel material for pump trucks, which contains chemical element components and mass percentages: carbon 0.2-0.4, silicon 1.4-1.7, manganese 4.2-4.4, chromium 1.7-2.1, molybdenum 0.4-0.7, aluminum 0.1-0.3, boron 0.3-0.5, titanium 0.5-0.8, La0.04-0.07, S≤0.04, P≤0.04, the balance is iron.
[0014] The production method of the high wear-resistant alloy steel material for the pump truck is as follows:
[0015] (1) Prepare pig iron and scrap iron as the source of iron matrix at a ratio of 1:0.7, put pig iron into the furnace for melting, desulfurize, deoxidize, use refining agent for one-time refining, add alloy components for alloying, and then add scrap iron to melt , adding refining agent for secondary refining, testing and adjusting the content of chemical elements to pass, casting, post-casting heat treatment, etc.;
[0016] (2) The order of batches of alloying elements added to the furnace during the alloying process is: (1) silicon, mangan...
