我们为了扩大针状硬质合金来源，在云南省地质局领导下，队、厂紧密配合，用冲床、硅碳棒电炉等简易设备，第一批加工成针状硬质合金块8000余块，经过试验，效果良好。一、制造工艺我们是用冷压浸渍法加工针状硬质合金块的，工艺分为配料、压制、烧结和产品检验。分述如下：1、配料：所需设备为5公斤天平一架，自制混粉机一台，10公斤棱形混料桶2个。按
In order to expand the source of acicular cemented carbide, under the leadership of Yunnan Bureau of Geology, teams and factories work closely with the first batch of more than 8,000 pieces of needle-shaped cemented carbide blocks processed by simple equipments such as punch press and silicon carbide rod furnace, After testing, the effect is good. First, the manufacturing process We are using cold pressing impregnated needle carbide block, the process is divided into ingredients, pressing, sintering and product testing. The points are as follows: 1, Ingredients: The required equipment for a 5 kg balance, a homemade powder mixer, 10 kg prismatic mixing bucket 2. press
