Embodiment Construction

[0010] 1. The composition and ratio of casting charge: pig iron 100%, manganese steel 19-22% (66%), ferrosilicon 2.7-3.4% (75%), rare earth magnesium alloy 0.42-0.50 (No. 6).

[0011] 2. Casting ingredients and front furnace control:

[0012] Pig iron composition: C 4.3%, Mn0.57%, Si1.28%, S0.03%, P0.05%

[0013] Manganese steel composition: containing Mn63.5%

[0014] Rare earth magnesium alloy composition: Mg9.11%, Ca2.20%, Si40.20%, Re9.20%

[0015] 3. Furnace front control:

[0016] Hot metal out of the furnace temperature: 1370 ~ 1400 degrees

[0017] Nodulizer: Magnesium iron 1.0~1.8%, plus 3% ferrosilicon

[0018] When processing, add a nodulizer with a particle size of 5 mm to the bottom of the molten iron ladle, cover the top with inoculated ferrosilicon and plant ash, and then pour it into the molten iron at one time. After the nodularization reaction is stable, skim off the dregs and pour the test rod.

Abstract

The invention relates to a novel material for casting a sub-soiling shovel, which is prepared by using a casting method. The material comprises the following casting components in percentage by weight: 100 percent of cast iron, 19 to 22 percent (66 percent) of manganese steel, 2.7 to 3.4 percent (75 percent) of ferrosilicon, and 0.42 to 0.50 (No.6) of rare-earth magnesium alloy. The sub-soiling shovel manufactured by using the wear resistant material has excellent wear resistance, toughness and casting performance, and has low price, firmness, wear resistance and long work cycle.

Description

technical field [0001] The invention relates to a new material for casting deep loosening shovel Background technique [0002] When the subsoiler is working, the main component consumed is the subsoiler, because the subsoiler is completely traveling in the soil during operation, and its surface is worn by soil particles for a long time. Therefore, the wear resistance of the subsoiler determines the quality of the subsoiler. overall performance of the machine. The subsoiler of the existing subsoiler is mainly 65Mn, the price is relatively high but the wear resistance is poor, and it is frequently replaced during operation. Its chemical composition and mechanical properties are as follows: [0003] [0004] [0005] In addition, the subsoilers of imported subsoilers are mostly made of manganese-titanium alloy, but the price is high, and it is difficult to manufacture small batches, so they mainly rely on imports. Contents of the invention [0006] The object of the p...
