The role and development of hot rolling group in steel production

1、 Core role: a hub for efficient production and quality control The hot rolling group is the core link in achieving continuity, automation, and efficiency in steel rolling production, and its role runs through the entire process from raw materials to finished products: 1. Continuous production to improve efficiency Through the series design of rough rolling and precision rolling, the hot rolling group directly rolls the heated slab into the required specifications of strip steel, eliminating the intermediate cooling and reheating steps. For example, the 2300 production line of Benxi Iron and Steel has increased its hourly output from 360 tons to 420 tons by optimizing the rolling rhythm, resulting in a significant improvement in efficiency.

Application of Composite Skateboards

Composite skateboards enhance performance through material composite technology and demonstrate unique advantages in various fields such as sports equipment, rail transit, bridge engineering, and industrial machinery. The following are specific application scenarios and analysis: 1、 Sports equipment field: lightweighting and performance improvement 1. Skateboarding Sports Traditional materials: Early skateboards were made of solid wood or 7-layer maple plywood, which had problems such as heavy weight and easy deformation. Application of composite materials: Modern skateboards incorporate glass fiber, Kevlar fiber, or carbon fiber composite layers into maple structures, significantly improving strength, flexibility, and durability. For example, carbon fiber composite layers can reduce the weight of skateboards by 30% and improve their impact resistance by 50%. Environmental Trends: Some brands use bio resins, natural fibers (such as flax and bamboo), or recycled materials

Installation and maintenance of rolling mill step pad

1、 Installation steps 1. Equipment cleaning and inspection ● Comprehensive cleaning: before installation, the contact surface of the ladder pad body, base and memorial archway shall be thoroughly cleaned to remove oil stains, iron filings and other impurities, so as to prevent poor contact or wear caused by foreign matters after installation. ● Key component inspection: Check whether the steps of the step pad are flat and whether the height difference between adjacent steps is consistent (usually designed as the same difference). Confirm whether the slag discharge groove is unobstructed to avoid residual processing residues

The function of bearing seat

Bearing seat is a key component used to support and fix bearings in mechanical equipment. Its core function is to provide stable and reliable support for rotating shafts or transmission components, ensuring smooth operation of the equipment. The following are the specific functions and key details of the bearing seat: 1、 Core functions 1. Supporting rotating components The bearing seat carries the weight of transmission components such as rotating shafts, gears, pulleys, etc. through built-in bearings (such as rolling bearings or sliding bearings), and transmits the radial force (such as gear meshing force) and axial force (such as threaded transmission thrust) generated by motion.

Overview and working principle of phosphorus removal valve

1、 The core function of phosphorus removal valve The phosphorus removal valve is a key executing component of the high-pressure water descaling system, mainly used to remove the oxide scale (primary and secondary oxide scales) on the surface of steel billets during the steel rolling process. Its core functions include: Accurate control of high-pressure water flow: intermittent spraying of high-pressure water onto the surface of steel billets is achieved through rapid opening/closing. Adapt to complex working conditions: It needs to withstand high pressure (usually 10-40MPa, or even higher), high temperature (the surface temperature of the steel billet can reach over 1000 ℃), and high-frequency actions (dozens of times per minute).

The characteristics and craftsmanship of skateboarding in Southeast Industry

The technical indicators of the composite skateboard we have developed have reached the performance of the same imported product, and its service life is comparable to that of imported composite skateboards. It is 4-5 times larger than nitride steel sliding plates and fully meets the conditions to replace imported composite sliding plates, fundamentally solving the supply of spare parts for medium thick plates and hot rolling mills.
