Factors Influencing Price
Raw Materials
1. The core is the alumina ceramic sheet. The alumina content determines its hardness and wear resistance.
2. Low-end products have an alumina content of around 70%, resulting in limited hardness and a short lifespan. High-end products have an alumina content of over 95%, a hardness close to Mohs 9, and excellent wear resistance, but the higher the content, the higher the cost.
3. The density and dimensional accuracy of the ceramic sheet also affect its wear resistance. Low-density material is prone to microcracks and easy to break off under high impact, while high-density material offers high compressive strength, resistance to cracking, and a long lifespan.
Production Process
Dry pressing offers low cost and is suitable for large production runs, but has limited density and average wear resistance.
Hot pressing uses high-temperature pressure to form the product, resulting in a dense structure, high cost, and excellent performance.
Vacuum sintering is an advanced process that allows for a long product lifespan, but the price is 20%-30% higher than standard products. Some companies use traditional processes to save costs, resulting in price differences between similar products.
Installation Method
Adhesive installation: Low cost, fast, and cost-effective, but high temperatures (over 200°C) can easily cause the ceramic sheet to break off.
Stud welding: Studs are welded onto a steel substrate and then secured to the ceramic plate. This method offers high installation costs but provides a secure bond and is suitable for high-temperature, high-impact environments.
Dovetail groove + glue + studs: This integrated process combines strength and flexibility, offering a long service life but also high costs. The installation method affects both initial investment and overall lifecycle costs.
A steel plant purchased two types of lining plates
Scheme A: Low-priced lining plate, unit price is about 140USD/㎡, pasted and installed, the actual life is partially fallen off in less than 8 months.
Scheme B: High-quality lining plate, unit price is about 210 USD/m2, fixed studs, actual life exceeding 2 years and still intact and few maintenance times.
The results show that although the initial investment of high-quality lining plates is high, their life span is more than 3 times, and the overall cost is lower.
Balance price and use value
The price difference between wear-resistant ceramic lining plates is essentially the difference in quality. When purchasing:
1. Focus on the alumina content rather than just looking at the quote.
2 . Preferring to mature processes such as hot pressing and vacuum sintering to avoid low-end processes.
3. Choose the appropriate installation method according to the working conditions and do not greed for the low-price paste method.
4. Comprehensive ROI calculates the comprehensive ROI in combination with lifespan and maintenance costs.
5. Select manufacturers with engineering cases and complete after-sales service, to control the budget and ensure the long-term and stable operation of the equipment.
The price of wear-resistant ceramic lining is affected by multiple factors such as raw materials, production technology, and installation methods. Low-priced products seem to save procurement costs, but their short lifespan and frequent maintenance increase long-term costs. When purchasing, enterprises should consider the price and life in a comprehensive way, and choose appropriate lining to reduce costs and increase efficiency to improve equipment operation stability.
