Casting rolling, also known as ingotless rolling, is a combined forming method of casting method and rolling method.

Casting and rolling is a new process that directly "casts and rolls" metal melt into semi-finished billets or finished products. The distinctive feature of this process is that the crystallizer consists of two rotary cast rolls with a water-cooled system, and the melt is solidified and hot-rolled between the roll seams, and in a very short time (2 3s).

Casting and rolling is a new type of technology developed in the 70s of the 20th century, and its advantage is that the molten metal liquid is directly crystallized, cast and rolled by rotating crystallizers to produce metal material products.

The rolling mill is also known as the roller machine, the roller press, and the calender. Its composition is mainly composed of rolling mill archway, bearing seat, base roll, roll gap adjustment system, transmission device, upper roll balance device and roll changing device.

Hello The rolling mill is generally composed of main equipment and auxiliary equipment.

Rolling mill equipment includes finishing rolling, finishing and roller table equipment. According to the different uses of various mechanical equipment, it can be divided into main equipment and auxiliary equipment.

The primary device is generally referred to as a host or host column.

The main engine column is usually composed of three parts: the main motor, the main drive, and the working frame. The form of the main motor is mainly determined according to the speed regulation needs of the rolling mill in the work.

The main drive is generally composed of a reducer, a herringbone gear seat, a main coupling and other transmission devices.

On some large rolling mills, such as two-high reversible primary rolling mill and four-high reversible steel plate rolling mill, there is a reducer and gear seat in the main drive.

The rolling mill working base is composed of a frame, a roll, a roll bearing and a press-down balancing device, etc., and the mind and structure of these parts are mainly determined by the purpose of the rolling mill.

Answer: a, b, c, d

This question examines the types of rolling equipment. The correct options are all metallurgical equipment for steelmaking and rolling, and the interference item E is mining beneficiation equipment, which does not belong to the smelting category.

According to the different products rolled, it can be divided into 1, bar and wire rod rolling equipment 2, plate and strip rolling equipment 3, profile rolling equipment 4, pipe rolling equipment.

According to the process route and use of rolling, it can be divided into: 1, feeding equipment 2, heating equipment 3, rolling equipment 4, collection equipment 5, finishing equipment 6, packing equipment 7, shearing equipment 8, public auxiliary equipment.

Due to the wide variety of rolled products and different specifications, some products are produced after multiple rolling. The management of the equipment in the rolling mill is very important. At present, the internationally recognized, relatively perfect and scientific equipment management method is the spot inspection and repair system.

Its purpose is to obtain equipment status information, formulate effective maintenance strategies, and make the maintenance work before the equipment accident, so that the equipment is always in a controlled state of management. For example, in the waste incineration power plant, the use of this Siyi checker directly uses a mobile phone or tablet, as a part of the instrument, in addition to the powerful system running speed, the smartphone also has all the other functions: mobile phone intercom, photography, video, NFC electronic tag, flashlight, 4G, WiFi, Bluetooth, instant messaging, etc.

Moreover, the use of these functions is familiar to the majority of users, and they can be operated without training.

Rolling mills are divided into cold rolling and hot rolling.

Rolled products are divided into, plates, strip steel, section steel, wire rod, flat steel, round steel bars, steel pipes, the specifications between their products are not the same, so that the corresponding equipment is not the same, now you understand, the equipment of the rolling mill is very complex, there are many types, the technology is different in different years of equipment, there is no way to introduce you here, because there are too many, it is best, you take a look at the relevant equipment books, slowly understand.

It is composed of two pieces of "torii" to install the roll bearing seat and the roll adjustment device, which must have sufficient strength and rigidity to withstand the rolling force. There are two main types of rack forms: closed and open. The closed frame is an integral frame with high strength and rigidity, which is mainly used for primary rolling mills and strip rolling mills with large rolling forces.

The open frame is composed of two parts, the frame body and the upper cover, which is convenient for roll change and is mainly used for horizontal profile rolling mills.

In addition, there is a mill without an archway. A device used to lift the upper roll and prevent the impact of the roll when the roll enters and exits the roll. The forms are: spring type, mostly used in profile rolling mills, heavy hammer type, commonly used in primary rolling mills with large roll movement, hydraulic type, mostly used in four-high strip rolling mills.

In order to improve the utilization rate, the rolling mill is required to change the roll quickly and easily. There are four types of roll change methods: C-hook type, sleeve type, trolley type and whole frame roll change type. The first two ways are used to change the roll and rely on the crane to assist the operation, while the whole frame needs to have two sets of stands for the roll change, and this method is mostly used in small rolling mills.

Trolley roll changers are suitable for large rolling mills and are conducive to automation. Nowadays, fast automatic roll changers are used in rolling mills, and it only takes 5 to 8 minutes to change a roll. It is composed of an electric motor, a reducer, a gear seat and a connecting shaft.

The gear seat distributes the transmitted torque to two or several rolls.

Ancillary equipment includes equipment for a series of auxiliary processes in the rolling process. Such as raw material preparation, heating, steel turning, shearing, straightening, cooling, flaw detection, heat treatment, base block thicket pickling and other equipment.

Lifting and transportation equipment, cranes, transport vehicles, roller tables and transfer machines, etc. The ball mill has a spiral semi-circular groove of the rolls, and the bar stock is rolled into a ballot ball by spiraling between the rotating rolls, and can roll a ball with a diameter of 60 650 mm.
