Steel coil, also known as coil steel. The steel is hot pressed and cold pressed into a roll shape. In order to facilitate storage and transportation, it is convenient to carry out various processing (for example, processing into steel sheets, steel strips, etc.).
Rotary Rings are a type of rotating seal widely used in various rotating equipment, such as rotary joints, rotary couplings, rotary connectors, etc. Its main function is to prevent liquid or gas leakage and maintain the normal operation of the equipment. In different applications, the material, structure, sealing method, size, etc. of Rotary Rings vary to adapt to different working conditions.
The materials of Rotary Rings are mainly divided into two categories: metallic and non-metallic.
Metal materials mainly include stainless steel, steel, copper, aluminum, etc., which have characteristics of high strength, corrosion resistance, wear resistance, and are suitable for rotary seals in harsh environments such as high temperature, high pressure, and high-speed.
Non metallic materials mainly include ceramics, silicon carbide, graphite, etc., which have characteristics such as high hardness, high wear resistance, and low friction coefficient. They are suitable for rotary seals under conditions such as low temperature, low pressure, and high speed.
The Rotary Rings with a unidirectional rotation structure can only rotate in one direction and are suitable for devices with only unidirectional rotation.
The Rotary Rings with a bidirectional rotation structure can rotate in two directions, suitable for devices that require bidirectional rotation.
The Rotary Rings with a rotating stationary structure are composed of a rotating ring and a stationary ring. The rotating ring contacts the stationary ring during rotation to achieve sealing, suitable for equipment that requires a rotating stationary seal.
The sealing methods of Rotary Rings are mainly divided into mechanical sealing and liquid sealing.
Mechanical sealing is achieved through the contact surface between the rotating ring and the stationary ring, which has the characteristics of high reliability, long service life, and simple maintenance. It is suitable for rotary sealing in harsh environments such as high speed, high temperature, and high pressure.
Liquid sealing is achieved by injecting liquid between the rotating ring and the stationary ring, which has the characteristics of good sealing performance, low friction coefficient, and preventing dry friction. It is suitable for rotary sealing under low speed, low temperature, low pressure, and other conditions.
The size of Rotary Rings is mainly determined by the equipment requirements, including inner diameter, outer diameter, thickness, shaft diameter, etc.
Steel coil, also known as coil steel. The steel is hot pressed and cold pressed into a roll shape. In order to facilitate storage and transportation, it is convenient to carry out various processing (for example, processing into steel sheets, steel strips, etc.).
The forming rolls are mainly hot rolled coils and cold rolled coils. Hot rolled coil is a processed product before re-crystallization of the billet. Cold rolled coil is the subsequent processing of hot rolled coil. The steel coil generally has a weight of about 15-30T. This year, China's hot rolling production capacity has been expanding continuously. There are already dozens of hot rolling production lines, and some projects are about to be built or put into production.
Steel coils are sold mainly for large customers, and general users do not have unwinding equipment or limited usage. Therefore, the subsequent processing of steel coils will be a promising industry. Of course, the current large steel mills have their own open and flat projects.
