The purpose of steel rolling production line is to obtain the required shape, such as steel plates, strip steel, wire rods and various sections, another aspect, in order to improve the internal quality of steel like common automotive plates, bridge steel, boiler steel, pipeline steel, etc. Steel rolling is a continuous and uninterrupted operation. The steel strip runs fast on the roller table with automated equipment bringing high efficiency. Depending on the different temperatures in the rolling method, the steel rolling can be classified into hot rolling and cold rolling. According to the different relationships between the relative movement of the rolling stock and the roll during rolling, it can be divided into vertical rolling, horizontal rolling, and diagonal rolling. In the hot rolling production line, the billet is heated to become soft and is sent into the rolling mill by the roller table, finally rolled to the size required by the users. Compared with hot rolling, the processing line in a cold rolling mill is more scattered. The steel coils sent by the hot rolling mill must undergo three consecutive technical treatments and the oxide film must be removed with hydrochloric acid. Through the cold rolling mill, the uncoiler opens the steel coil and then the steel strip is carried to a five-stand continuous rolling mill to be rolled into a thin strip coil.

Many people have the same question, what is the relationship between the spring starter and the electrical starting system, and what is the connection between them? What scenarios are they applied for? We compared their characteristics and development trends and compiled the following information for you.

What’s the Application of Electrical Starting System?

The electrical starting system was first invented in 1915 in purpose to reduce injury cases of operators who started vehicle engines with hand cranks. The power and convenience provided by electric starters established the dominance of automobiles containing internal combustion, as seen to this day. Electric starters also allowed more powerful engines to be safely implemented, contributing to the rise of automobile, and it’s also widely applied in other industrial machinery and equipment. Even though the electric starter is ubiquitous, back-up spring-powered engine starters have been developed to overcome a dead battery or other electrical issues.

What’s the Application of Spring Starter?

Spring starter is not a regular device for daily use. Instead, it’s a device that will provide mechanical starting when the battery of electric starter lacks power, which makes emergency/auxiliary generator sets more reliable to meet the requirements of firefighting, emergency rescue, military, marine, or some other harsh environments. The units of energy input, storage, transfer, and release are integrated into one spring starter assy. Requiring no external systems, the spring starter is a little larger than an electric starter. It only needs manpower to wind the input adaptor by winding handle, and the springs inside will be compressed to store energy. By pulling the trip lever, energy will be released to turn the engine flywheel. Then the engine gets started. Precisely because of these characteristics，where applications require rapid extraction of energy, springs starters (and other mechanical starter systems) have an advantage.

As the damages caused by the electrostatic discharge on sophisticated components have been valued more and more by the companies from various industries, ESD workbench has been widely used in factory workshops.

What is ESD Workbench

The ESD workbench, also known as an anti-static workbench, is a type of workbench, widely used in the electronics industry and the places with strict anti-static electricity requirements. It can guarantee the safety of electrostatic-sensitive components.

Principle

The anti-static workbench table is generally made of anti-static melamine high-pressure decorative laminate which also is known as anti-static fireproof board and the conductive substrate. The conductive substrate is generally conductive particleboard or a graphite composite board so that the tabletop has overall anti-static performance. Static electricity can be directed to the ground through an anti-static surface or a ground wire.

Composition

The composition of the anti-static workbench mainly includes the workbench frame, workbench top, drawers, boards, lighting lamps, socket panels, grounding wires, etc.

Frame

The frame of ESD workbench adopts industrial aluminum profile, also known as an all-aluminum frame. The frame has a simple structure, without welding, easy to disassemble, with strong expand-ability. It is beautiful, resistant to corrosion, no dust, no fingerprints, easy to clean, and has a long service life.

Ground wire

The ground wire is to let static electricity discharge to the ground smoothly, so the ESD workbench must be installed with a ground wire for better anti-static function. Drawers, sockets, lighting can be customized according to different needs.

Countertop Materials

1. Heavy-duty anti-static workbench top with 50mm thickness

2. Light anti-static workbench desktop with 30mm thickness

3. Stainless steel worktable top with 30mm, 50mm thickness

4. carbon steel work table countertop with 30mm, 50mm thickness

Installation

1. Ensure the size of the anti-static table mat according to the work requirements. Thoroughly clean the lower surface, the upper surface of the table mat and each component.

2. Lay foil tape on the lower surface of the anti-static table mat and aluminum foil is only allowed to overlap at the folding place. Pressing the knob joint from the front of the anti-static table pad can be replaced with other nuts to make it pass through the table pad and foil tape to ensure good electrical contact.

3. Lay the prepared anti-static table mat on the work surface flatly. And ensure the area of anti-static mats according to the range of activities of the worker. Place the workbench on an anti-static floor mat.

4. The ESD workbench is grounded, and the anti-static desk mat and ground pad are connected in series with a resistor to the ground wire configuration system with a cross-sectional area of stranded copper core flexible wire or cable. It is best to inspect before use after installation.

ESD workbench has the outstanding function of anti-static for the places with high requirements of Electrostatic Discharge protected, widely used in the electronics industry for electronics production, repairing, testing, and any work-related to electronics.

The steel bar production line with the annual capacity of 50K to 300K tons for the production of bars Φ8-32mm of common carbon steel, wire rod steel and low-alloy steel. The production Line uses 100×100–150×150 continuous casting billet, which of length 3000mm–6000mm and provided by the internal steelmaking continuous casting workshop. The annual output of 50,000-300,000 tons requires 330,000 tons of continuous casting billet, and the comprehensive finished product rate is 98% (considering negative deviation).

Wire Production Line

The wire production line of TINVO has an annual production capacity of 50K to 300K tons and can produce welding rod steel, Φ5.5-Φ20mm round bar, bearing steel, etc. The whole line adopts full continuous twistless rolling, and the finishing mill adopts high-precision cantilever rolling mill with high rolling speed, high output, high product precision and high mechanical performance. The main equipment includes rough rolling, Pre-finishing rolling mill, finishing mill which is a cantilever type twistless high-speed heavy duty rolling mill, pinch roller, wire laying machine, flying shears, water cooling system, transmission and automation.

The process characteristics of high-speed wire rod rolling mills can be summarized as continuous, high-speed, twistless and controlled cooling. Heavy-duty, high-precision, and excellent performance are the product characteristics of high-speed wire rod mills.

High-speed wire production has the following characteristics:

1) High speed of small diameter roller. High-speed wire rod finishing rolling mills generally use tungsten carbide as the rolling tool, with a diameter of 8 or 6 inches. The speed of the finished product can be up to 9000 r/min.

2) There are many racks and different functions. Each rolling mill only rolls once, so modern wire rolling production line has generally 21-28 rolling mills divided into rough rolling, intermediate rolling, pre-finishing rolling & finishing rolling mill. The rough rolling, intermediate rolling using larger extension and multi-groove rolling and finishing rolling using smaller extension and multi-line rolling to achieve both balances the production capacity of each unit and ensure the dimensional accuracy of the product.
