The production process of Zhuzhou cemented carbide plate is as below. Powder making→formulation according to the requirements of use→wet grinding→mixing→crushing→drying→sieving→then adding forming agent→drying again→sieving to make the mixture→granulation→pressing→forming→sintering→forming (blank)→flaw inspection→packaging→warehousing.
Cemented carbide piston rod is a metal rod in the piston pump, using the process of powder metallurgy preparation, the plunger is mainly in the pump or compressor to transport fluid, so for the plunger rod requirements are high, wear-resistant, high hardness, corrosion resistance, long service life, with this feature can reduce the replacement of the plunger rod, reduce business costs and expand the efficiency of machine operations. Next together with the working principle of the carbide plunger rod.
The use of counterweights is used as a way of maintaining balance. Their weight is generally calculated according to the strength of the machine itself and must not be too heavy or too light. If it is too heavy, there is a high risk of damage to the strength of the vehicle when lifting the weight; conversely if it is too light, there is a high risk of rollover. In order to make the vehicle more versatile, some large tonnage cranes have removable counterbalance blocks. When lifting small tonnage materials, the crane can be hung with less or no counterbalance blocks. However, it should be noted that when lifting large tonnage goods, the balancing blocks must all be hung, and even overweight devices must be added to prevent accidents from occurring and causing irreparable consequences. This shows the importance of tungsten alloy counterweight blocks.
Carbide rotary file is widely used in machinery, automobile, shipbuilding, chemical industry, craft carving and other industrial departments, with remarkable effect, the main uses are:(1) fine processing of various metal mold cavity, such as shoe mold and so on.(2) all kinds of metal and non-metal c
