Functions and Types of Flying Shears in Steel Rolling Mills
The Use and Classification of Flying Shears in Steel Rolling Mills
A shear machine used to transversely cut moving rolled stock is called a flying shear. With the advancement of continuous plate mills, structural steel mills, and billet mills, coupled with the increasing productivity of flying shears, their applications have become increasingly widespread.
Flying shears come in a wide variety of types and are widely used: disc-type flying shears, dual-drum flying shears, crank-rotary flying shears, and swing-type flying shears, among others.

Are you familiar with low-temperature rolling?
Low-temperature rolling involves heating steel billets to temperatures lower than conventional heating levels, followed by rolling performed at these reduced temperatures—more precisely referred to as medium-temperature rolling. The primary goal is to significantly cut down on fuel consumption required for billet heating and minimize metal burn-off during the process.

A Comprehensive Guide to Documents for Handling Metallurgical Engineering Qualification Services
Metallurgical engineering qualifications represent the construction capabilities of a company and are also crucial documents for engineering bids. Therefore, before a company can participate in metallurgical engineering projects, it must first complete the qualification application process. Generally, the application involves three key steps: meeting the eligibility criteria, preparing the required documentation, and submitting the qualifications. Among these steps, preparing the various materials is where mistakes most commonly occur. Since these materials are submitted to the relevant authorities for review, any errors or omissions could significantly impact the final outcome. Sichuan Haobang Qualification Services has carefully compiled common issues and their solutions, outlining the specific process as follows:
1. Submit the application form through the Ministry of Housing and Urban-Rural Development’s official website for construction industry enterprise qualification applications.

Universal Rolling Mill: What are the tips for using a universal rolling mill?
Solving the Oil-Leakage Issue in Universal Rolling Mills:
1. For sealing at the joint surfaces, apply 601 and 602 rubber coatings to the mating surfaces of the housing sections to effectively address oil leaks.
2. At the bearing ends, install screws opposite to the direction of rotation on the oil rings positioned between the bearings and end caps. Additionally, add a comprehensive sealing ring to the end cap itself and fit an external housing around the shaft—this design ensures both a tight seal and protection against dust. Maintenance can be further enhanced by applying sealant to the sealing rings.
Typically, either of these methods is sufficient to resolve oil-leakage problems. However, if neither approach works, the universal rolling mill will require professional repair.

What are the main factors affecting the rolling pressure in a steel rolling mill?
Rolling pressure is crucial for steel rolling mills, as it is the force that enables plastic deformation during the process. There are three primary factors that significantly influence the rolling pressure in steel mills: 1. Temperature effects, 2. Work hardening impacts, and 3. The interplay between workpiece thickness and roll diameter. Below, Fuzhou Jinquan Metallurgical Machinery Equipment Co., Ltd. will provide a detailed explanation of how these three factors affect steel rolling operations.

The Importance of Daily Maintenance for Structural Components of Rolling Mills
As a widely used steel rolling machine, the rolling mill requires particularly important daily maintenance to ensure smooth operation. It’s crucial to note that inadequate daily upkeep can significantly shorten the machine’s lifespan. Each day, inspect the rolling mill for leaks of oil, water, or air, as well as any signs of overheating in its components. Additionally, minimizing losses caused by improper equipment operation or delayed maintenance is essential. When lifting and moving the rubber rolls, be sure to take necessary precautions—such as ensuring proper alignment of chains, ropes, and roll surfaces—to maintain optimal performance and safety.
