What is Nodulizer?

一月 11, 2023

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.

Hot Rolling VS Cold Rolling

三月 06, 2022

Hot Rolling VS Cold Rolling What are the differences between hot rolling and cold rolling? This is also a matter of concern. Although they are all rolled, they are still very different and applicable to different situations. Therefore, it is necessary to analyze and introduce them in detail so that we can distinguish and use hot rolling and cold rolling. The specific analysis is as follows. The hot-rolled plate has low hardness, easy processing, and good ductility. The cold-rolled sheet has high hardness and relatively difficult processing, but it is not easy to deform and has high strength. The hot rolled plate has relatively low strength and poor surface quality, but good plasticity. It is generally a medium and thick plate. Cold-rolled plate: it has high strength, high hardness, and a high surface finish. It is generally a thin plate and can be used as a stamping plate. The mechanical properties of hot-rolled steel plate are far inferior to cold working and forging, but it has bet

Functions of Reheating Furnace Control System of Rolling Mill

三月 04, 2022

Functions of Reheating Furnace Control System of Rolling Mill In order to make the statistical processing and high efficiency for quality operation management, a special database is compiled. The combustion control is carried out according to the secondary temperature distribution heat transfer model of the slab section. In rough and finish rolling, it is calculated based on the rolling quantity of each pass, The automatic rolling line is controlled by the rolling mill, the plane shape is controlled, and the accelerated cooling is determined according to the heating rolling temperature and processing history, but the dynamic cooling conditions are controlled. The functions of the heating furnace control system are as follows: (l) Calculate the slab temperature in the furnace. Measure the slab temperature at the inlet of the heating furnace, and calculate the slab surface and internal temperature with the heat transfer model according to the corresponding heating history. (2) Combustio

Hot Rolling Process

三月 03, 2022

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

七月 23, 2021

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 sheets, and delami

Sendzimir 20 High Mill

三月 11, 2021

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 anne
