In the process of hot rolling production line, the discharged steel billet heated from the heating furnace to the target temperature first passes through the high-pressure water descaling box to remove the scale, and then enters the roughing mill stand area.
Therefore, reducing the consumption of bearings is of great significance to reduce the production cost of narrow strip steel.
Generally, turbo-generators are not prone to failure under the correct use and maintenance, but if they are improperly used and maintained, the environment is poor, and they are in disrepair for a long time, they will also cause failures.
A steam turbine generator is a generator driven by a steam turbine. The superheated steam generated by the boiler enters the steam turbine and expands to do work, which makes the blades rotate to drive the generator to generate electricity.
Bucket wheel stacker and reclaimer, as an efficient continuous loading and unloading machine, is widely used in the yard of ore and coal bulk cargo terminals.
Bucket wheel stacker and reclaimer refers to a high-efficiency loading and unloading machine used for continuous conveying of both stacking and reclaiming materials in large dry bulk storage yards.
The function of electric furnace steelmaking in the process is to process raw materials into molten steel with qualified composition and temperature at a certain rate.
The electric arc is the heat source in the electric arc furnace, which determines the thermal conditions in the furnace. Due to the characteristics of the arc itself, it determines the electrical characteristics of the electric arc furnace equipment. This in turn determines all aspects of electric arc furnace steelmaking.
The blast furnace centrifugal fan is mainly composed of a static part and a rotating part. The static part consists of the casing, the air inlet pipe, the bearing, the sealing device, the fan expander, the return device and the air outlet pipe. The rotating part consists of the rotor and the impeller mounted on the main shaft of the rotor, the thrust plate, the balance wheel, etc.
Air separation equipment refers to a device that uses air as raw material to separate various gases such as oxygen and nitrogen in the air by cryogenic separation or adsorption separation. The air separation plant is mainly composed of eight systems, namely compression system, purification system, refrigeration system, heat exchange system, rectification system, product conveying system, liquid storage system and control system.
Air separation equipment is a device that uses air as raw material, converts the air into liquid state by means of compression cycle deep freezing, and then gradually separates it from liquid air to produce inert gases such as oxygen, nitrogen and argon through rectification.
Electric furnace steelmaking mainly uses arc heat. In the arc action zone, the temperature is as high as 4000 °C. The smelting process is generally divided into a melting period, an oxidation period and a reduction period. In the furnace, not only an oxidizing atmosphere but also a reducing atmosphere can be created, so the efficiency of dephosphorization and desulfurization is very high.
Rotary drum dryer, also known as drum drying equipment, is the most common and widely used type of dryer equipment in mining equipment. It is suitable for drying magnetic, heavy and floating concentrates of metallic and non-metallic ores, clay in cement industry and slime in coal mining industry.
The submerged arc furnace is used for the reduction and smelting of metal oxide ore, so it is also called the submerged arc reduction electric furnace.
The rolling mill is mainly composed of rolls, rolling mill arches, bearing packages, bearings, worktables, rolling guides, rail seats, roll adjustment devices, upper roll balance devices and roll changing devices.
Cold rolling mills mainly roll coils or pickled steel from pickling lines with cooling oil at ambient temperature. Cold rolling mills produce steel and stainless steel, aluminum, foil and copper. There are many types of rolling mills, such as 2-High, 4-High, 6-High, 12-High, 20-High, Sendzimir mill, etc. (there are many types in terms of shape control operation).
Blast furnace smelting is an important process in iron and steel production, and its blast furnace smelting equipment consists of blast furnace body, blast furnace dust collector, blast furnace blower, blast furnace hot blast stove, molten iron tanker, etc.
In recent years, due to the inferior, poor, miscellaneous and refractory iron ore resources in my country, fine grinding must be carried out in order to improve the utilization efficiency of iron ore, which can result in the majority of domestic iron concentrates with fine particle size.
The ball mill is the key equipment for the material to be crushed and then crushed. This type of grinding machine is to put a certain number of steel balls in its barrel as grinding medium. It is widely used in cement, silicate products, new building materials, refractory materials, fertilizers, ferrous and non-ferrous metal beneficiation and glass ceramics and other production industries, dry or wet grinding of various ores and other grindable materials.
The industrial rotary drum dryer is mainly composed of a rotating body, a lifting plate, a transmission device, a supporting device and a sealing ring. The working principle is that the slag is sent to the hopper by the belt conveyor or the bucket elevator, and then enters the feeding end through the feeding pipeline through the feeding machine of the hopper.
