High-Hardness Metallurgical Steel Rolling Knife Yuxin Oem For Industrial Manufacturing
Metallurgical steel rolling blades are the core tools used in the steel industry for rolling, shearing and splitting steel strips. They are known as the “sharp teeth” for steel forming. By means of the moving upper blade and the fixedl lower blade, with a reasonable blade gap, they apply shear force to various thicknesses of metal plates, causing the plates to break and separate according to the required dimensions. They have extremely high requirements for hardness, wear resistance and heat resistance.

Features:
- Extremely high hardness and wear resistance: Hardness reaches HRC 60+; wear resistance is 3-5 times that of ordinary steel, suitable for continuous shearing of high-hardness materials.
- Surface treatment: TiN/TiAIN coating or chrome plating process, friction coefficient reduced by 40%.
- Impact resistance and toughness: The base material contains chromium, molybdenum, tungsten, etc., bending strength is increased by 30%, preventing chipping and fracture during high-speed shearing.
- Thermal stability: Resistant to 800℃ high temperature, low thermal expanson coefficient, avoiding thermal deformation; internal cooling technology or alloy overlay layer enhances heat resistance.
- Precision adaptability: Supports customized dimensions, suitable for shearing machines, longitudinal shearing machines, and cross-cutting machines, etc.
Application Scenario: Bar material cutting, sheet material splitting (such as cold-rolled sheets, stainless steel sheets, etc.), stainless steel precision cutting (such as 304/316 stainless steel), scrap steel processing, steel recycling plant, waste steel bar cutting, medium-thick steel plate cutting, etc.

Industrial Grade Tungsten Carbide Circular Blades For Precise Strip Cutting Durable And Suitable
Tungsten steel round blades are usually made from high-quality tungsten carbide alloy (mainly composed of tungsten carbide and cobalt) through powder metallurgy process. 。 This process endows the blade with extremely high hardness, wear resistance and thermal stability, making it highly suitable for high-speed and precise cutting operations. It is applicable for cutting metals, plastics, composite materials and other hard materials. Depending on the shape and design, common tungsten steel round blades include flat round blades and toothed round blades, etc.
Precision Rotary Shear Knife Circular Slitting blade Used for metal processing
The Rotary shear blades , also known as the strip divider blade or the rolling shearing machine blade, is the core cutting tool for the thin sheet metal shearing process. Through the rotation and shearing of the upper and lower blades, wide rolls of material can be precisely cut into narrow strips of specific widths. They are usually composed of three parts: the blade, the spacer sleeve, and the spacer ring. Their diameters range widely, from 100mm to 2000mm, to meet different processing requirements - larger diameter blades are mostly used for heavy-duty sheet metal processing, while smaller diameter blades are suitable for precise cutting. They are widely used in metal processing, automotive manufacturing, and electronic and electrical industries.
Steel Plate Shearing Machines Blades Manufacturer for Metal Guillotine Long Knives
The shearing machine blade is the core cutting component of the shearing machine, consisting of an upper blade (moving) and a lower blade (fixed). By adjusting the blade gap reasonably, it applies cutting force to the metal sheet to achieve precise cutting of straight edges. Its working principle is based on the mechanical structure of forging machinery and is widely used in industries such as light industry, aviation, shipping, metallurgy, electrical appliances, and stainless steel products.
