Cold-rolled spiral blades**, do you know?Let's take a look!
Cold-rolled spiral blades**.
Cold rolling refers to the spiral blades obtained by continuous and uninterrupted cold rolling steel strip with a spiral blade cold rolling mill.
This kind of spiral blade has a high surface finish and strong wear resistance, which is twice as wear-resistant as the general spiral blade. The pitch, inner diameter and outer diameter dimensions are standard and accurate. The length is adjustable.
The cold-rolled steel strip is generally made of carbon steel, manganese steel or stainless steel, and is not easy to corrode and rust after pickling, increasing its own service life.
Cold-rolled spiral blades vary according to their material, diameter, pitch, thickness and purchase amount. Details**It is best to consult with the manufacturer.
Cold rolling refers to the spiral blades formed by cold rolling of spiral blades in a cold rolling mill, which can produce spiral blades with a thickness of 6 thicknesses or less than 6 thicknesses, also known as auger blades, and the spiral blades produced have a smooth surface, high hardness and good wear resistance.
Spiral blades are the main components of screw conveyors, which are widely used in biofuel pellets, agriculture, grain, food, chemical, pharmaceutical, mining and other industries.
With the continuous improvement of the user's requirements for the quality of cold-rolled strip, the plate shape quality has become one of the most important indicators of high-quality cold-rolled strip, therefore, the research form control technology has been the focus of the investigation of cold automation, and the control system is the cold rolling mill plate to be developed and utilized to meet the requirements of the flatness control accuracy as the starting point, the adjustment system of detection, according to the adjustment ability of the plate shape adjustment mechanism and the operation of the cold rolling mill, so that the shape of the steel plate is adjusted to dynamic characteristics.
Nowadays, a preferential setting strategy for the plate shape adjustment mechanism is provided, the calculation process is set up using the influence of the functional method as an example, a configuration model of the objective lens curve in the shape of a slat, which controls the crown, straightness control and subsequent processing requirements of the strip, and is studied according to the actual production situation to develop the geometry of the transversely wound strip, which is set to a shape different from the strip edge temperature.
On this basis, the software structure of the target shape of the bending plate is developed based on the actual situation of production, and the practical application of the structure of the target shape of the bending plate is verified, a self-learning model of the plate shape control efficiency is developed, a multivariate algorithm is established based on the efficiency coefficient of the shape control of the plate, a multivariable algorithm is established to control the optimal shape using a least-squares algorithm with limitations, a deviation control strategy for the shape of the relay method is established, a variable gain compensation method is provided before adjusting the adjustment of the shape adjustment mechanism, the influence of the detection link reduction in the control system is analyzed, and the compensation scheme of the system reduction is studied。
Therefore, the ** device is introduced into the closed control system in the form of a plate to compensate for the reduction, and the first and model experiments of the shape control system are carried out, the first results of the shape control system are analyzed, and different closed-loop control methods are formed according to the different cold rolling mill speeds, and the effect of the application of the relevant model is studied through the calculation of theoretical analysis and actual rolling experiments according to the on-site production conditions.
