斗齿是矿用挖掘机不可缺少的消耗量很大的易损件。我们本着在现有矿山机修的条件下,用最少的成本、最简单的工艺,生产出矿山所需要的耐磨斗齿,参加了冶金部1980～1981年在攀钢兰尖铁矿4米~3挖掘机斗齿攻关试验,获得了较好的效果。在矿岩硬度f=10～14的情况下,每组六个斗齿挖掘总量达464239吨,为符山铁矿定额的6倍,也超过了冶金部所要求的独立机修厂在1985年达到40万吨的目标。现将高锰钢斗齿生产工艺介绍如下: 一、冶炼与化学成份在1.5吨电炉上,采用氧化法冶炼,炉料
Bucket teeth is an indispensable mine excavator consumable consumption of large parts. We have the spirit of the existing mining mechanized conditions, with the least cost, the simplest process to produce the necessary wear-resistant teeth mine, participated in the Ministry of Metallurgical 1980-1981 in Panzhihua Iron and Steel Mine 4 meters ~ 3 excavator bucket teeth tackle test, get better results. In the case of ore rock hardness f = 10 ~ 14, the total digging amount of each group of 6 teeth reached 464,239 tons, which is 6 times of that of Fushan Iron Mine and also surpassed the independent mechanical workshop required by the Ministry of Metallurgy in 1985 Achieve the goal of 400000 tons. Now high manganese steel bucket tooth production process is as follows: First, smelting and chemical composition 1.5 tons electric furnace, the use of oxidation smelting, charge
