introduction：Tension controller（Tension controller）It is a system developed by a single chip microcomputer or some embedded devices and peripheral circuits，Its a control instrument，It can directly set the tension value required for control，Then feed the tension sensors signal directly（Generally in the millivolt class）As a tension feedback value，After the deviation is obtained by comparison，Input intoPIDWait for the controller to process，It is best to output to the peripheral actuator to control，Finally, the deviation is minimized，System response fastest purpose。 In the industrial control industry，In some ribbon and line type products，It is often necessary to control tension to meet production requirements，The tension controller is a kind of instrument that controls this kind of tension。The tension controller also has a so-called manual control function，Generally, it means that the human can give a certain output to the actuator through the tension controller（Often the current flow of the motor）；The general tension

introduction：Carbon steel is a mass fraction of carbon less than2.11%Steel without specially added alloying elements，Sometimes also known as plain carbon steel or carbon steel。There are cold rolling and hot rolling process production。But cold-rolled and hot-rolled plates arent just carbon steel。Hot and cold rolling is divided from the process，Carbon steel、Low alloy steel、Alloy steel is divided by composition。Dont mix it up。 What is the difference between low carbon steel and cold rolled steel？ For the difference between mild steel and cold rolled steel，You cant really compare these two： First of all, low carbon steel is the classification of steel with carbon content in steel，Aritaka、In the、Mild steel Class III，Cold rolled steel refers to a division of steel plate rolling methods，Partial cold rolling、Hot rolled two kinds。 secondly，For cold rolling，Usually low carbon steel plate is used for cold rolling，High carbon steel，Generally not suitable for cold rolling into cold rolled steel plates，Of cours
