The Difference between Two-high Rolling Mill and Four-high Rolling Mill

图片
The difference between Two-high Rolling Mill and Four-high Rolling Mill Many friends do not know what is a four-roll mill. In fact, the four-roll mill is a combination of two working rolls and two supporting rolls. It belongs not only to the driving machine of backup rolls but also to the equipment driven by working rolls. Therefore, the specific choice should be made according to the requirements of customers, and also to the actual use situation. What is the difference between a two-roll mill and a four-roll mill? For a two-roll mill, the whole diameter of the roll is relatively large, and the contact area between the roll and the tie piece is also very large, so the whole rolling force is relatively large, so there are certain requirements for the selection of rolling materials and thickness, so as to effectively avoid many unnecessary problems in the whole rolling process. Four-high rolling mill also increases in roll system, so its working roll diameter can be much small...

Sendzimir 20 High Mill

图片
  Sendzimir 20 High Mill The essential difference between Sendzimir cold rolling mill and four high rolling mill or other types of rolling mill is the different transmission direction of rolling force. The rolling force of the Sendzimir cold rolling mill is transferred from the work roll to the backup roll device through the intermediate roll, and finally to the solid overall stand. This design ensures the support of the work roll in the whole length direction. In this way, the roll system deformation is very small, and the very accurate thickness deviation can be obtained in the whole width direction of rolling. Sendzimir mill has the following main characteristics in structure and performance (1) The frame with integral casting (or forging) has high rigidity, and the rolling force acts radially on each section of the frame. (2) The work roll diameter is small, and the pass reduction rate is large, up to 60%. Some materials can be rolled into very thin strips without intermediate ...

Hot Rolling Process

图片
Hot Rolling Process The semi-finished billet from the steelmaking plant is rolled to make it a qualified product. Introduction of Hot Rolling Process Process Flow of Hot Rolling: Process Flow of Main Rolling Line: The slab is directly sent to the slab warehouse of the hot rolling workshop from the slab discharging roller table of the continuous caster in the steelmaking and continuous casting workshop, and the directly hot charged slab is sent to the furnace loading roller table of the heating furnace for heating. The slab that cannot be directly hot charged is lifted into the insulation pit by the crane, then lifted to the upper material bench by the crane after insulation, and then heated by the furnace loading roller table of the heating furnace, leaving the possibility of direct rolling. The continuous casting slab is transported into the slab warehouse by the continuous casting workshop through the slab loading roller table or slab unloading roller table. Before the slab reaches t...

Difference Between Hot Rolled and Cold Rolled Stainless Steel

图片
Difference Between Hot Rolled and Cold Rolled Stainless Steel Both hot rolling and cold rolling are processes for forming section steel or steel plate. They have a great influence on the structure and properties of Bai steel. The rolling of steel is mainly hot rolling, and cold rolling is only used to produce small section steels and thin plates.  Hot Rolling Advantages :  It can destroy the casting structure of the steel ingot, refine the grain of the steel, and eliminate the defects of the microstructure so that the steel structure is dense and the mechanical properties are improved. This improvement is mainly reflected in the rolling direction so that the steel is no longer isotropic to a certain extent; bubbles, cracks, and looseness formed during casting can also be welded under high temperature and pressure. Disadvantages:  1. After hot rolling, the non-metallic inclusions (mainly sulfides and oxides, as well as silicates) inside the steel are pressed into thin shee...

What is Nodulizer?

图片
What is Nodulizer? Nodulizer, also known as rare earth magnesium ferrosilicon alloy（FeSiMg）, is an additive that can promote the crystallization of graphite into spherical cast iron. The main component of the “Nodulizer agent” is nodularizing elements, such as Mg, Ce, Ca, etc. The Ferro silicon magnesium nodularizer can significantly enhance the strength of cast iron. And it also features the function of degasification, desulfurization, and deoxidation. The nodularizer is widely used in the metallurgy and steel-making industry. Size:5~15mm, 3~25mm, 8~40mm, 25~50mm, or as per customers’ requirements. Packaging Details: Waterproof Plastic woven bag, 1 ton/bag or according to customer requirements. Storage: Dry storage. Avoid contact with moisture.

Rebar Rolling Mill Production Process

图片
Rebar Rolling Mill Production Process First, the Production Process of Rebar Rolling Mill Rebar is a ribbed steel bar, also known as a ribbed steel bar, usually with two longitudinal ribs and horizontal ribs evenly distributed along the length. The shape of the horizontal ribs is spiral, herringbone, and crescent. Expressed in millimeters of the nominal diameter. The nominal diameter of the ribbed steel bars is equivalent to the nominal diameter of the light round bars with equal cross sections. The nominal diameter of the steel bar is 8-50 mm, and the recommended diameter is 8, 12, 16, 20, 25, 32, 40 mm. Ribbed steel bars are mainly subjected to tensile stress in concrete. Ribbed steel bars have a greater bonding capacity with concrete due to the role of ribs, and therefore can better withstand external forces. Ribbed steel bars are widely used in various building structures, especially large, heavy, light thin-walled and high-rise building structures. Rebar is produced by ...
