In the process of filling and solidification,molten metal acts with the mold in a thermal, physical, chemical and mechanical manner. Due to these effects, casting defects such as sand entrainment, sand hole, porosity, sand sticking, surface oxidation or decarbonization may occur. l Thermal actionWh

A pillow block is a pedestal used to provide support for a rotating shaft with the help of compatible bearings & various accessories. Housing material for a pillow block is typically made of cast iron or cast steel. A pillow block usually refers to a housing with an included anti-friction bearing. A

Stainless steel has the ability to resist atmospheric oxidation, that is, rustless property, and also has the ability of corrosion resistance in acid, alkali and salt medium, that is, corrosion resistance. However, its corrosion resistance is changed with the chemical composition, protection state, use condition and environmental medium type of the steel itself.

Metals are easy to corrode and rust in the natural state, thus increasing the loss of metals and reducing the service life. Therefore, in order to increase the wear resistance, corrosion resistance, aesthetics and other functions of metals, it is necessary to protect the metal surface. Metal surface

Pouring process is a crucial link in the whole production process of steel castings.The pouring process is not simply pouring the metal liquid into the cavity, because the molten steel in the process of melting, casting, and solidification will be connected with the surrounding medium (such as air, various refractory materials, etc.). A series of physical and chemical reactions will occur due to the impact of high temperature and fluid. Impurities, they will remain in the various parts of the casting.

Non Destructive Testing is called NDT. It is a technology that uses the principles of ray, ultrasound, infrared, electromagnetic and other principles without damaging or affecting the performance of the detected object, and combining the instruments with the instrument to detect the defects, chemical and physical parameters of the material, parts and equipment. Non destructive testing can detect defects in materials and workpieces, as well as the surface and inside, and can also measure the geometric features and dimensions of the workpiece, and can determine the internal structure and state of the material or the workpiece.

Do you know how long any hydraulic pump should last? In this industry, using past experience might not always deliver the answers you were hoping for, and are likely to give you answers that are actually no better than guessing. Disappointingly, there is no dependable approach to determine how long your hydraulic pump will last. Using historical data is perhaps something that will give you the best indicator, but if it’s a new pump and you have no data – that’s where the guessing game beings. Fortunately, there are a number of factors that determine how long any pump will last and using these can give you an estimate that is more informed.

What is the Hydraulic System?A hydraulic system is a drive technology where a fluid is used to move the energy from e.g. an electric motor to an actuator, such as a hydraulic cylinder. The fluid is theoretically uncompressible and the fluid path can be flexible in the same way as an electric cable.

Cast irons are a family of iron-carbon alloys. Their high carbon content (usually 2–4%) gives cast iron its characteristic hardness. To facilitate a better understanding of these materials, they can be divided into five groups, based on composition and metallurgical structure: white cast iron, malleable cast iron, grey cast iron, ductile cast iron and alloy cast iron.

What are the mechanical properties of steel?The properties of metal materials are generally divided into two categories: process performance and service performance. Process performance refers to the mechanical properties of metal parts in the process of cold and hot processing.
