Analysis of tungsten alloy balancing block
Tungsten alloy counterweight block can be simply understood as a counterweight block mainly made of metal tungsten material, so it is also called tungsten alloy counterweight. Because of its excellent physical and chemical properties, it is favored by researchers in the fields of military, national defense, aerospace, aviation, navigation, automobile, medical treatment, electronics, petrochemical industry and so on.
The properties of tungsten alloy counterweight
It is non-toxic, high melting point, high density (2 times of lead), strong rigidity, high hardness, excellent shielding effect and good thermal conductivity and other characteristics.According to different composition, the composition of tungsten alloy products can be divided into tungsten alloy, tungsten-nickel-iron, tungsten-nickel-copper and tungsten-nickel-copper-iron;According to the different magnetism, tungsten alloy products can be divided into magnetic tungsten alloy and non-magnetic tungsten alloy.
Production method of tungsten alloy counterweight：
(1) Dividing the large counterweight into several small counterweights below 50Kg;
(2) According to the mass percentage of the following components: tungsten powder 91% ~ 95%, nickel powder 3.50% ~ 7.5%, iron powder 1.0% ~ 3.0%;
(3) the three kinds of raw material powder is weighed, mixed and pressed into a small counterweight blank, and then liquid phase sintering;
(4) the sintered small counterweight needs to connect the surface, processing into a plane, one of the small counterweight placed on the sintering boat, the connecting surface to maintain a level or perpendicular to the sintering boat, and then put another small counterweight and a small counterweight before the two connecting surface fit placed together, other small counterweight is also placed in the same way;
(5) Finally, all the small counterweights together with the sintering boat are put into the fixed-point hydrogen furnace for liquid phase sintering, and the product can be obtained.
The use of tungsten alloy counterweight：
(1) Used in automobiles. The tungsten alloy balancing block has great flexibility in automobile design, and can keep the wheel dynamic balance at high speed rotation.
(2) Used in cranes. The use of the balance block in the crane can significantly increase the weight of the crane to lift the weight of the heavy objects.
(3) Used in machine tools. This can effectively reduce the load of the motor and the lead screw, inhibit the heating of the motor and the lead screw, so as to ensure the processing accuracy, prolong the life of the corresponding parts.
