What are the use of stainless steel coils?
Adaugat pe 07/05/2019 04:57:47

Like other types of stainless steel plates, stainless steel coils are highly resistant to corrosion and rust, and their excellent quality makes them an important industrial raw material and building material. With the continuous development of the national economy, the application fields of stainless steel coils are more and more extensive, and the market prospects are very favored by the industry. The following is a small series to introduce the use of stainless steel coils.


1. Automotive industry


Stainless steel coils are not only resistant to corrosion, but also light in weight. Therefore, they are widely used in the automotive industry. For example, automotive shells require a large number of stainless steel coils. According to statistics, a car needs about 10-30 kg. Stainless steel coils, while American cars require 40 kg of stainless steel coils. Nowadays, some international brands have begun to use stainless steel coils as structural materials for automobiles. This will not only greatly reduce the weight of the vehicles, but also greatly improve the service life of the vehicles. In addition, stainless steel coils are becoming more and more widely used in buses, high-speed rails, and subways.


2. Water storage and transportation industry


Water is susceptible to contamination during storage and transportation, so the storage and transportation equipment used is critical. Storage and water transport equipment based on stainless steel coils is currently recognized as the most hygienic, safest and most efficient water industry equipment. At present, the sanitary requirements and safety requirements for the storage and transportation of production and domestic water are getting higher and higher. The storage and transportation equipment of traditional materials can no longer meet our needs. Therefore, stainless steel coils will become important water storage and transportation equipment in the future. Production of raw materials.


3. In the construction industry


Stainless steel coils are originally used in the construction industry. They are important building materials in the construction industry or raw materials for the production of building materials. The decorative panels of the exterior walls of the building and the interior wall decoration are generally made of stainless steel coiled sheets, which are not only durable but also very beautiful. With the continuous development of interior decoration, more and more stainless steel coils are used as decorative materials in the home improvement industry. Stainless steel coils of various appearances can not only be used as outsourcing of buildings, but also can be made into various decorative boards. .


In addition to being used in the two main areas mentioned above, stainless steel coils are also used in the home appliance manufacturing industry. Stainless steel coils are used in the production of many components such as televisions, washing machines, and refrigerators. As the home appliance industry continues to be hot, there is still much room for expansion in the application potential of stainless steel coils in this field.

Qingdao small concrete pump truck price
Adaugat pe 28/04/2019 04:55:17
When the small concrete pump truck is in normal fabric, it needs to constantly change the posture of the boom, because the center of gravity of the pump will change with the change of the posture of the boom. During the construction of the pump truck, the vibration of the boom and the collapse of the ground will also change the center of gravity of the vehicle. If the center of gravity exceeds the range of the legs, it will lead to rollover.
Pump trucks need to pay attention to when using them. Nowadays, many manufacturers have added intelligent anti-flip measures. There are two main types of measures: checking the tilting device of the pumping truck and detecting the force of the supporting leg. The tilt sensor senses the level of the pump and can send horizontal angle information to avoid rollover caused by ground subsidence. The force sensor of the leg can detect the force of the leg, and can promptly issue a warning or suspend the current pumping when the leg is unevenly stressed. However, it is worth noting that artificial intelligence is not omnipotent. Therefore, a good pumping operator is needed at the construction site. It is more effective to artificially judge the sudden situation on the site than artificial intelligence. Therefore, it is necessary to remind the customer of the need for the pump operator. Timely skills training, the accumulation of pumping experience in the first place.
