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.

"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.

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.

The dilution rate is less than 10%, so even with a 1mm build-up layer, the performance and functionality of the build-up material can be fully demonstrated. Due to the low heat input, it is possible to build up on thin and small-diameter materials, which was difficult with conventional arc/plasma welding. We also provide machining finishing after the build-up. We have various types of metals for welding, so please feel free to contact us.
