How to choose the speed chart of reversible rolling mill and whether there is a reversible cold rolling mill?

How to choose the speed chart of reversible rolling mill and whether there is a reversible cold rolling mill?

Rolling mill, which can be said to be a wide variety, and the following is to introduce one of the specific types, is a reversible rolling mill, because it is in the website products, and is also one of the main keywords of the website. In addition, we should take this work seriously, because only in this way can we have a correct understanding of the reversible rolling mill and know how to use it reasonably and avoid problems such as wrong use.

Roll material and heat treatment process

Roll material and heat treatment process

The life of the roll mainly depends on the internal performance and working force of the roll, and the internal performance includes strength and hardness. In order to make the roll have sufficient strength, it is mainly considered from the roll material; hardness usually refers to the hardness of the working surface of the roll, which determines the wear resistance of the roll and the service life of the roll to an appropriate extent. Reasonable material selection and heat treatment can meet the hardness requirements of the roll.

Billet continuous casting machine hydraulic shear maintenance and maintenance you don't know

Billet continuous casting machine hydraulic shear maintenance and maintenance you don't know

Hydraulic shear is a very important equipment in continuous casting production, hydraulic shear is a way of continuous casting machine cutting billet, the use of hydraulic shear directly affects the production of continuous casting machine. Hydraulic shear is the main equipment of continuous casting machine, because of its direct contact with high temperature casting billet and in bad working environment. High temperature makes the hydraulic shear hydraulic cylinder, blade and limit easy to damage, and the frame is easy to deform. However, the life of any equipment can not be unlimited, equipment in the use of time is likely to have some problems, so that production is difficult to continue. In order to extend the service life of the equipment, maintain production and reduce costs, do a good job in the daily maintenance and maintenance of hydraulic shears, maintenance is essential.

Effect of Cold-rolled Sheet Type with Different Processes on Pickling and Straightening

Effect of Cold-rolled Sheet Type with Different Processes on Pickling and Straightening

The flatness of cold-rolled stainless steel strip is one of the important indicators to reflect the product, with the downstream process flat, sanding, embossing, grinding 8K and other requirements for the flatness of the strip is becoming more and more stringent, in the rolling annealing and pickling of the strip straightening, has become a necessary process for more and more manufacturers. During the cold rolling process of stainless steel strip, the strip steel has plate defects due to poor roll shape and poor roll gap shape. These defects occur as a result of the uneven longitudinal extension of the strip in the width direction and the disturbance of the rolling stress. After recrystallization annealing, pickling and leveling, in order to eliminate the plate defects of the strip and make the internal stress tend to be uniform, it is necessary to draw and straighten the strip to further improve the flatness of the strip.
