Preparation method of ceramic reinforced wear-resistant form relieved teeth
The invention discloses a preparation method of ceramic reinforced wear-resistant form relieved teeth. The preparation method comprises the following steps of smelting an alloy steel raw material in amedium-frequency induction furnace to obtain molten steel; pouring to obtain a form relieved tooth base body; after cooling, raising the temperature to 560-600 DEG C at the speed of 50-65 DEG C/h, preserving heat for 30-60 minutes, raising the temperature to 650-700 DEG C at the speed of 75-80 DEG C/h, preserving heat for 30-50 minutes, raising the temperature to 900-950 DEG C at the speed of 69-73 DEG C/h, preserving heat for 100-120 minutes, after air cooling, heating to 910-925 DEG C, preserving heat for 10-20 minutes, after water cooling, heating to 500-550 DEG C, preserving heat for 1-2hours, after air cooling, heating to 270-310 DEG C, preserving heat for 2-4 hours, and after air cooling, obtaining a semi-finished product; and according to the working stress condition of the form relieved teeth, determining that the upper surface and the lower surface of a tooth top are abraded parts, coating the abraded parts with ceramic slurry after the abraded parts are polished and cleaned, and conducting heating curing.
本发明公开了一种陶瓷增强耐磨铲齿的制备方法，包括：将合金钢原材料放入中频感应炉内熔炼得到钢水，浇注后得到铲齿基体，冷却后以50‑65℃/h的速率升温至560‑600℃保温30‑60min，以75‑80℃/h的速率升温至650‑700℃保温30‑50min，以69‑73℃/h的速率升温至900‑950℃保温100‑120min，空冷后加热至910‑925℃保温10‑20min，水冷后加热至500‑550℃保温1‑2h，空冷后加热至270‑310℃保温2‑4h，空冷后得到半成品；根据铲齿的工作受力状况，确定其齿尖上、下两个表面为磨损部位，对磨损部位打磨清洗后涂覆陶瓷料浆，升温固化。
