In the steel rolling production line, there will be some surface defects in hot rolled steel. The reasons for the defects are generally caused by the immaturity of the process. Today we will analyze the causes of the defects on the surface of the hot rolled steel and the solutions to these surface defects. Common…

In steel rolling production, the casting process is a common manufacturing method. Casting is the pouring of molten metal into a mold, where the molten steel cools and then solidifies to obtain parts of the desired shape and properties. The advantages of this production process are low manufacturing costs and great process flexibility. The casting…

In the rolling production line, the rolling mill is the most important equipment. During operation, the rolling mill rolls will generate a large radial force, and the high-speed rotation of the work roll will cause fatigue pitting corrosion of the bearing. Therefore, in the rolling production line, the wear of the rolls has always been…

Today we will explain to you the term “annealing” about the rolling production line. Annealing is a metal heat treatment process: the metal is slowly heated to a certain temperature, held for a sufficient time, and then cooled at a suitable rate. The purpose of annealing is to: Improve or eliminate various structural defects and…

On the steel rolling production line, there are two common rolling mills: tandem rolling mill and tandem rolling mill. Today, the editor of Judian will introduce these two rolling mills to you. The first is the tandem rolling mill, and the structure is generally three-roll or two-roll alternating. It is mainly used to produce various…

Currently, there are many types of continuous casting machines and methods. And, each of them has the specific characters. Today, Judian will introduce the common types of continuous casting machine and methods to you. The continuous casting production process usually has the following requirements for the equipment: 1. The equipment must adapt to the whole…

With the refinement of metal materials, the requirements for forging heating temperature have also increased. In the past, only looking at the brightness of heated forgings to determine the temperature of forgings has been phased out, and induction furnace temperature sorting equipment is gradually becoming the main equipment for temperature measurement of forgings. So, what…

The mechanical equipment of the rolling workshop can be divided into main equipment and auxiliary equipment according to their different roles in production. The main equipment of the rolling mill is generally the main engine row. The main engine column is generally composed of three parts: the main motor, the rolling mill and the transmission…

In the process of rolling profiles by rolling mills, there are usually two processes of rough rolling and finish rolling, one of which adopts continuous rolling and the other adopts a combined rolling
