View Tech Specifications >As the Republic of Rwanda executes its ambitious Vision 2050 development strategy, the expansion of local manufacturing, mineral processing, and infrastructure construction has driven demand for robust engineering solutions. Industrial operations in Rwanda face unique geographic and logistical realities. Transporting raw machinery parts from coastal ports (Mombasa or Dar es Salaam) to landlocked Kigali is expensive and time-consuming.
Hence, extending the operational lifetime of existing machinery components through surface hardfacing is a critical strategy for local cement producers (such as CIMERWA), brick factories, mining operators, and road construction firms. By using high-alloy flux-cored wires (FCW) to rebuild and overlay worn components, plants can reduce downtime and lower replacement costs.
Industrial equipment in mining and quarrying fails due to three main wear mechanisms: severe low-stress sliding abrasion, high-stress grinding abrasion, and impact-induced deformation. Standard carbon steels degrade rapidly under these conditions. Developing an effective wear barrier requires deposition of high-chromium cast iron alloys that precipitate hard primary M7C3 chromium carbides (with microhardness values up to 1500 HV) within a tough eutectic matrix.
Without proper wear mitigation, quarry hammer crushers, cement vertical mill rollers, and mining chutes require replacement every few months. Runxing's specialized chromium carbide alloys ensure your operations stay online longer, minimizing shipping dependencies.

In Rwanda’s diverse operational settings—ranging from enclosed cement plants to open-air coltan quarries in Southern Province—welders face changing environments. Gas-shielded wire relies on constant flow of Argon/CO2 mixtures, which is easily disrupted by wind in open mines. Our Self-Shielded (Open-Arc) Hardfacing Flux Cored Wire features integrated gas-forming flux agents inside the tubular core, forming its own protective canopy. This simplifies equipment needs and cuts logistical costs by removing the need for gas bottles.

Explore Solutions >Industrial components are heavy and difficult to ship. Runxing Machinery works with our authorized export agent, Hebei Yuwan International Trade Co., Ltd., to manage the logistics of shipping heavy welding materials and oversized wear plates to East Africa. We optimize the shipping process to minimize delays and clear customs smoothly.
Products are shipped from major ports in northern China (such as Tianjin or Shanghai) directly to Mombasa Port in Kenya or Dar es Salaam Port in Tanzania. From these coastal hubs, cargo travels via the Northern or Central Corridor roads through Uganda or Tanzania into Rwanda. We secure all necessary shipping documents, certificates of origin, and compliance paperwork to ensure clear customs clearance at the Kigali dry port (Kigali Logistics Platform in Masaka).
Rwanda has a humid tropical highland climate with two distinct rainy seasons. This humidity can cause bare steel and low-alloy welding wires to rust, which can lead to porosity and failure in the weld. Runxing prevents this by packing all hardfacing flux-cored wires in vacuum-sealed plastic bags, protective desiccant packs, and sturdy, double-walled outer carton drums. This ensures your welding consumables arrive in optimal condition, ready for on-site fabrication.

Selection depends on the primary wear mechanism. For high-stress grinding abrasion (e.g., coltan and tungsten scrapers/chutes), choose high-chromium flux-cored wires such as our gasless OEM self-shielded wire. If the parts experience severe impact (e.g., quarry hammers), use complex carbide alloys containing Niobium (Nb) and Molybdenum (Mo) to prevent premature cracking under stress.
Yes. Standard CC/CV welding machines can run self-shielded flux-cored wire, provided the wire feeders are fitted with knurled drive rolls (V-knurled) to avoid crushing the tubular wire. The polarity must also be changed to DCEN (Straight Polarity: Electrode Negative, Workpiece Positive) for optimal deposition and minimal spatter.
The total transit time is typically 45 to 60 days. This includes 25–30 days for ocean freight from Tianjin Port to Mombasa or Dar es Salaam, followed by 10–15 days for land transport along the Central or Northern Corridor, customs processing, and final delivery to Kigali.
All Runxing products conform strictly to international standards, including ISO 9001:2015 for quality management systems and DIN 8555 for hardfacing filler metal specifications. Pre-shipment inspections by independent third-party agencies like SGS or Bureau Veritas can be arranged upon request.
Yes, CCO plates can be cold-formed. However, because the overlay features hard carbide crystals, bending must be done in the direction of the weld beads to prevent open cracks. We recommend a minimum bending radius of 20 times the total plate thickness to avoid excessive deformation of the base steel.
