The grinding surfaces of vertical mills (rollers and table liners) experience wear over time, leading to a decrease in grinding performance. To address this, hardfacing is applied to the rollers and table to enhance wear resistance and achieve a longer lifespan. Additionally, after a certain period of operation, repairs are conducted to restore the grinding surfaces to their original shape through re-hardfacing welding, aimed at recovering grinding performance. 【Features of Hardfacing Welding】 - By applying hardfacing to the worn areas of the rollers and table liners, a longer lifespan is achieved. - Hardfacing materials specifically developed for vertical mill rollers and table liners are used for the hardfacing welding process. - The vertical mill crushes the material to approximately 100μm using the rotating table and rollers. *For more details, please refer to the related links page or feel free to contact us.

"Gachikon" is a special overlay welding method that fuses cemented carbide particles in a dispersed state within a high-tensile steel matrix. It is a hybrid type of wear-resistant overlay welding that withstands wear from the target object with cemented carbide particles and impacts from collisions with the high-tensile steel matrix. It demonstrates its effectiveness against wear targets such as ores and crushed debris. 【Features】 ■ By applying Gachikon overlay to parts subjected to heavy wear, we aim to extend the life of your equipment components. ■ Reduces maintenance opportunities and achieves lower running costs. ■ Fuses cemented carbide particles in a dispersed state within a high-tensile steel matrix. ■ Demonstrates its effectiveness against wear targets such as ores and crushed debris. *For more details, please refer to the related link page or feel free to contact us.

"PTA" is an acronym for Plasma Transferred Arc Welding. As the name suggests, it is a welding method that uses a plasma arc for melting metals, and it utilizes powder as the welding material. Due to the characteristics of the PTA welding method, it is possible to perform overlay welding of superalloys such as Co-based alloys represented by Stellite, which are resistant to heat and wear, as well as Ni-based superalloys that are highly resistant to corrosion and heat. Additionally, overlay welding of wear-resistant alloys containing ultra-hard carbides like NbC can also be performed. **Features of PTA Welding** - Special welding materials that cannot be formed into wires or rods can be used in powder form. - By powdering the welding material, welding of composite alloys containing carbides can be easily carried out. - Thin overlays and internal diameter overlays that conform to shapes can also be applied. *For more details, please refer to the related link page or feel free to contact us.*

Build-up welding is a technique that involves welding different metals onto the surface of various metal materials (base materials) to restore the shape of areas that have been worn or damaged due to wear, cracks, corrosion, etc., and to improve surface properties such as wear resistance, corrosion resistance, and heat resistance. In particular, rolls and rollers used in continuous casting and rolling equipment related to steelmaking are subjected to harsh operating environments, and the extent of wear and damage due to heat, wear, and corrosion is significant. Our company not only focuses on restoring these base materials but also leverages the strengths of specialized welding material manufacturers to select welding materials that can withstand these operating environments, performing build-up welding to deliver products that match our customers' equipment. 【Features】 - Conduct surface modification aimed at restoring the shape of worn or damaged areas and improving wear resistance, corrosion resistance, and heat resistance. - Implement hard-facing build-up not only for worn rolls but also for surface modification of new rolls. - Utilize PTA welding to accommodate build-up welding of heat-resistant and wear-resistant superalloys based on Co and Ni. *For more details, please refer to the related link page or feel free to contact us.

The blades (mono-cutters) of the dual-axis crusher have traditionally used heat-treated materials such as SCM440, SKD61, and SKD11, which were replaced with new ones after wear. The blades made with specialized welding materials, referred to as Y0-CUTTER, not only increase the durability as blades but also allow for the repair of worn heat-treated blades. Please feel free to contact us when needed. 【Features】 ■ Uses specialized welding materials for blades ■ Increases durability as blades ■ Allows for the regeneration of worn heat-treated blades *For more details, please refer to the related link page or feel free to contact us.

When it comes to welding, the first thing that comes to mind is the welding of metal components, but our company possesses the most advanced technology not only in this area but also in another representative welding technique, build-up welding. As the term "build-up" suggests, we enhance the surface of various metal substrates by welding on equal or superior metals, thereby building up material and performing repair and regeneration (repair) on parts that have been worn or damaged due to wear, cracks, corrosion, or high-temperature oxidation. Additionally, we employ welding techniques for surface modification aimed at improving wear resistance, corrosion resistance, and heat resistance. In particular, surface modification known as hardened build-up welding, which is specialized for wear resistance, is one of our strengths. 【Features (Build-up Welding with Special Electrodes)】 ■ Instead of replacing worn or damaged parts with expensive new ones, we can relatively inexpensively reuse them through repair and regeneration (repair) using build-up welding. ■ We perform build-up welding with welding materials tailored to the purposes of heat resistance, corrosion resistance, and wear resistance on the surface of components, thereby enhancing their durability and extending their lifespan.
