The studed roller needs to rely on the high wear resistance of the cemented carbide studs to break the material, but the high hardness of the cemented carbide studs itself produces great stress deformation on the base material of the roller sleeve. Today, most roll press manufacturers use a special adhesive method to connect the carbide stud to the mounting hole in the base material of the roll cover. The bonding strength of cemented carbide stud and hole directly determines whether the cemented carbide nail can be fixed stably on the roll surface. Therefore, in order to ensure that the cemented carbide stud does not fall off, it is necessary to improve the strength of the hole wall of the carbide studs, select a high strength adhesive, and install the cemented carbide studs.

As one of the important parts of the crane, the counterweight block is mainly used to keep the balance of the crane. The best material for the counterweight block of the crane is tungsten alloy with high specific gravity. Although the production cost and price of tungsten alloy counterweight block are higher than lead, iron, but it is more practical, has longer life, relatively longer service cycle, low replacement frequency, reduce the cost. Its advantages are mainly the following three: Read More

Of course, the specific characteristic coefficient of tungsten rod is related to the ratio of raw materials. Most of them are alloy products with refractory tungsten as hard phase and cobalt, nickel, iron, copper and other metals as bonding phase. When the bonding agent is copper, the color, melting point, density and electrical conductivity of tungsten rod will be different. With the increase of copper content, the color of tungsten rod will tend to copper color, and the electrical conductivity is better. The melting point and density of tungsten rod will increase with the increase of tungsten content. Read More

Tungsten alloy is a kind of environmental protection alloy, its main components are tungsten, nickel, iron and other metal elements, the production process will not produce toxic substances, in the use of the process will not cause radioactive pollution, and tungsten alloy has the ability to resist radiation, so tungsten alloy in some areas instead of lead. Tungsten alloy ball are often used in the military field for shotguns, prefabricated fragments, armor piercing projectiles and so on. Read More

Cemented carbide studded roller has been widely used in cement industry raw material roller press. Because of its stable production operation rate, long service life and other advantages, favored by the cement industry. The studs used in roller press is tungsten cobalt carbide material, tungsten carbide (WC) as the matrix, cobalt (CO) as the bonding phase, made by powder metallurgy technology of high hardness, with high strength, good impact resistance wear resistant. The hardness of tungsten carbide studs HRA is about 87, which can greatly improve the service life and working efficiency of roller press, and has high wear resistance. Read More

Tungsten-cobalt carbide stud has the advantages of wear resistance and high hardness, but the anti-shear ability is slightly weak. There will also be damage in the process of use, such as fracture or accelerated wear and tear. In the production and operation of the studded-roller, the studded-roller is subjected to severe high stress abrasive wear, shear force damage and long-term fatigue damage. In the operation process, the studded-roller will fracture, peel off and serious wear problems, thus affecting the output and service life of the roller press. The common reasons for the damage of tungsten cobalt carbide stud are summarized here. Read More

If the hard alloy dynamic sealing ring is too tight, it is harmful and useless. First, it aggravates the wear between the sealing ring and the shaft sleeve, and causes premature leakage. Second, it increases the resistance of axial adjustment and movement of the moving ring, so it cannot be adjusted timely when the working condition changes frequently. Three is the spring overfatigue easy to damage; Fourth, the moving ring sealing ring deformation, affect the sealing effect. Read More

Tungsten alloy shielding parts are made of "high density alloy" - mainly tungsten as the main body, adding a small amount of nickel, cobalt and other elements, high density, strong hardness, environmental protection, non-toxic, radiation resistance, such excellent performance, so that the high proportion of tungsten alloy shielding parts in the medical field has a wide range of applications. Zhuzhou Jinxin can design and produce tungsten alloy shielding parts of special specifications and high quality according to different needs and specific scenes, to prepare different product characteristics, customized requirements, and solve enterprise troubles.
