Excavator bucket tooth and casting process
The casting technology comprises the following steps that S1, all raw materials which are calculated according to the proportion are added into an electric induction furnace for high-temperature smelting, and molten steel is obtained after deoxidation and deterioration; s2, WC, nano Al2O3, a binder and Co are weighed according to the proportion and put into a stirrer to be stirred for 1-2 h at the speed of 500-800 r/min, and a reinforcing material A is obtained; wC, nano Al2O3 and Co are weighed according to the proportion and put into a stirrer to be stirred for 30-40 min at the speed of 500-800 r/min, and a reinforcing material B is obtained; s3, an inner cavity of a casting mold is evenly coated with a reinforcing material A, molten steel with the temperature ranging from 1500 DEG C to 1600 DEG C is poured into the casting mold, the molten steel is taken out after being cooled and solidified, a casting head is removed, polishing is conducted, and the pretreated excavator bucket tooth is obtained; and S4, the reinforcing material B is evenly laid on the surfaces of the pretreated excavator bucket teeth, laser cladding is carried out, the multiple faces of the pretreated excavator bucket teeth are subjected to same treatment, cooling, heat treatment, air cooling and polishing in sequence, the abrasion-resistant excavator bucket teeth are obtained, the technology is reasonable, and the product practicability is high.
本发明公开了一种挖掘机斗齿及铸造工艺，包括以下步骤：S1：将按比例计算好的各原料加入感应电炉中进行高温熔炼，脱氧变质后，得到钢水；S2：将按比例计算称取WC、纳米Al2O3、粘结剂和Co放入搅拌机中以500‑800r/min搅拌1‑2h，得到增强材料A；将按比例计算称取WC、纳米Al2O3和Co放入搅拌机中以500‑800r/min搅拌30‑40min，得到增强材料B；S3:将增强材料A均匀涂覆在铸型内腔，将温度为1500‑1600℃的钢水浇注在铸型内，冷却凝固后取出，去除浇冒口并打磨，得到预处理挖掘机斗齿；S4：将增强材料B均匀铺在预处理挖掘机斗齿表面，进行激光熔覆，依次对预处理挖掘机斗齿的多个面进行同种处理，冷却后再予以热处理，空冷后打磨，得到耐磨型挖掘机斗齿，工艺合理，产品实用性强。
