The Features Of Furnaces And Matters Need Attention

The Features Of Furnaces And Matters Need Attention

It is necessary that explain what is a furnace. According to Wikipedia: “A furnace is a device used for high-temperature heating. The name derives from the Greek word Fornax, which means oven.”

Also, there was a popular statement that a furnace is a device that is used to heat the material in order to exchange its shape as like in shaping and forging or the properties of the material can be changed. These furnaces are mostly used for melting the metals that are used for casting. The furnace can be termed as a type of oven. In addition, it is an enclosed structure inside, which makes the material heated at very high temperatures. It can be designed to perform water or air heating as well as circulated throughout a building in a heating system.

Furthermore, the way of a furnace design like this has its advantages and features, which as a way to consume fuel and heat as less as possible in a given time that would require low labor costs at first. Second is the apparent efficient features: The amount of heat that is to be given is prior determined to the material. 

Therefore, there exists a sufficiency in the liberation within the furnace heat of the required material. Proper heat and temperature would be successfully transferred from the gases to the surface of the heating stock take place.

What calls for special attention is that temperature should be uniform within the stock. Making the heat loss from the furnace needs to be minimized to the least.

The Finishing Mill Group For High-Speed Wire-Rod Production

The Finishing Mill Group For High-Speed Wire-Rod Production

A rolling mill is a very useful machine manufactured by humans, one of its functions is to reduce the thickness of material quite accurately or compress the material to create wire rods, re-bar, cold coils, or other products.

At the same time, rolling mill machines are not standard machine tools, nor are they built for stock. They are built-to-order to specifically accomplish an end product or process.

During the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills, and blooming mills. So many years passed, and we still can see the contribution of this revolution time has made.

Nowadays, the steel rolling mill machine has made a very great improvement like the 135m finishing mill group researched by Hani Steel. 

The finishing mill group is the extra-heavy top 45° high-speed wire rod finishing mills designed for the high-speed wire rod production line. 

The finishing mill group is located in the high-speed wire rod workshop. Rolling by 10-unit rack continuous micro-tension rolling mill, rolling the ɸ17--ɸ21mm of rolled piece transported from upstream into ɸ5.5--ɸ16mm finished wire rod. The mill's guaranteed exit speed is 90m/s. ( when the specification of the finishing product is ɸ5.5mm).

The Historical Background Of Rolling Mill Development

The Historical Background Of Rolling Mill Development

The earliest known rolling mill of metals was around the fourteenth century, its very small rolls were used to flatten cold metals such as gold, and silver, or used in jewelry or works of art. As well as we knew that Leonardo da Vinci describes in his notes machines for the cold rolling of sheets and bars in 1480, but it is unlikely that these mills were ever constructed. Until the last half of the sixteenth century, the cold rolling particularly began to take on more importance as lead, began to be used for roofing and other applications such as organ pipes.

The seventeenth century saw the hot rolling of bars of ferrous materials into thin sheets throughout Europe and especially in Germany, with applications later in that century in England and Wales. These mills were single-stand mills. It was not until the eighteenth century that metal was rolled in successive stands arranged as a tandem mill, the first record of which was for the hot rolling of wire rods in England in 1766, and in 1798 a patent was issued for a tandem mill for rolling iron plates and sheets.

The History Development Of Rolling Mill

The History Development Of Rolling Mill

Hot and cold rolling mill between two or more rolls has been in existence since long before the industrial revolution. As a matter of fact, Leonardo da Vinci was credited for the metalworking mill prior to his death in 1519.

When most people think of a rolling mill, they visualize sizable machinery in ferrous (iron, carbon steel, and stainless steels) and non-ferrous (copper, brass, lead, etc.) integrated or electric arc furnace (EAF) steel mill of today, to small manually cranked rolling devices used at jewelers to reduce the thickness of the precious metal or impart a pattern on the surface of the metal to be fabricated into a chain or ring.

Rolling mills have many functions. They can be used to reduce the thickness of material quite accurately (+/-.0001”) or compress the material to create a uniform density throughout the strip or import a surface finish on one or both sides of the material, just to name the most common methods.                    

Rolling mills are not standard machine tools, nor are they built for stock. They are designed and built to order to specifically accomplish an end product or process.

At one point during the industrial revolution in America, the United States led the world in hot and cold rolling, plate mills, slabbing mills, and blooming mills. Companies such as Mesta, United, Blaw-Knox, Lewis, Continental, and Bliss were attributed to building some of the largest rolling mills in the world before World War II.

Many of these old mills are still running today as a result of upgraded electrical and hydraulic systems, including hydraulic screwdowns, hydraulic roll bends, and tension control.

The Main Tendency And Features Of Rolling Mill

The Main Tendency And Features Of Rolling Mill

Since the 1960s, with the development of iron-making and steel-making technology and the progress of the mechanical and electrical industry; with the wide application of computer automatic control technology and advanced science and technology, the production of steel rolling technology has made leaps in the growth and development. In a word, the main tendency and features of its development as the following:

1. The production process of strip and wire rods is continuous in the recent 20 years and would be more perfect if the continuous tube rolling mill and section continuous rolling mill came into being. And there are new types of rolling mills that were invented such as endless rolling, which is a completely continuous rolling production line. Including electric release ‘fat, annealing, cooling, k and coiling' process of finishing the rolling mill line also appeared in recent years cause of the widely applied wire rod mill in cold rolling belt californium and continuous welded pipe, which has greatly increased the production efficiency.

2. The constant improvement of rolling speed and the continuous production process created the condition of increased operating speed. All kinds of rolling mill speeds increased, Over the past 20 years. The Current wire rod rolling speed has reached 100 meters per second, cold rolled strip speed at 41.7m/s, and steel tube tension reducing speed up to 20 meters per second. And with the development of continuous automation, a variety of operating speeds will be increasing continuously. 

3. Production process automation is improving at all levels not only the important factor of production capability increased by technology and science but also the important prerequisite for improving product quality, labor-saving, and reducing consumption. The electronic computer developed after the 1960s has been applied more widely, especially the strip rolling has made the most full use of it. The currently used multi-level computer control system not only realizes the process control and digital direct control but also makes the computer technology applied by enterprise management. Many factories are expanding the electronic computer automatic control technology to the steel material finishing, heat treatment, nondestructive, and so on.

All in all, the increasingly large scale of iron-making and steel-making production capacity is bound to expand the rolling production scale.
