Everything you want to know before purchasing refractory materials
Do you have many questions when selecting and using refractory materials and ceramic fiber products? To help you find answers quickly and accurately, we’ve compiled a comprehensive FAQ. This page covers product performance, selection, application, customization services, and more, aiming to provide you with professional and clear references to make your purchasing decisions easier.
Which is better for my industrial furnace: refractory bricks or ceramic fiber blankets?
This depends on the specific needs of your furnace. Refractory bricks, known for their excellent structural strength and corrosion resistance, are typically used in the load-bearing and stress-bearing parts of the furnace. Ceramic fiber blankets, on the other hand, provide excellent thermal insulation, are often used to reduce heat loss, and can adapt to irregular interior shapes. Many projects use a combination of these two materials.
How can you ensure consistent quality across bulk refractory materials?
To ensure quality, request that suppliers provide quality inspection reports for each batch of products, including chemical composition, physical properties (such as bulk density and compressive strength at room temperature), and thermal properties (such as refractoriness and thermal conductivity). You can also request third-party sampling testing and review the supplier’s quality management system certification (such as ISO 9001).
How do I calculate freight and logistics costs for bulk purchases of refractory materials?
Freight costs for bulk purchases are typically calculated by tonnage or cubic meter. You’ll need to confirm with your supplier whether the terms are EXW (Ex Works), FOB (Free on Board), or CIF (Cost, Insurance, and Freight). Be sure to include all costs, including freight, insurance, customs clearance, and port charges, in your total cost calculation.
Are prices negotiable for large orders?
Yes, most suppliers offer tiered pricing for larger orders. You can request pricing for different quantities and negotiate with a sales representative for a more competitive quote. Contact us now for the latest refractory prices.
What is the shelf life of refractory materials? How should they be stored?
Most refractory bricks and ceramic fibers do not have a strict shelf life, but they do require proper storage. They should be stored in a dry, well-ventilated warehouse protected from moisture. Monolithic refractory materials (such as castables) require particular attention to their shelf life, as their composition changes over time.
How should damage during transportation be handled?
Upon receipt, inspect the goods immediately. If any damage is found, take photos and record them immediately, noting the damage on the delivery receipt. Notify the supplier and logistics company promptly to initiate a claim or reissue process. Proper packaging and loading procedures can effectively minimize damage.
How does your company ensure the consistency of chemical composition and stability of physical properties in large batches of high-alumina bricks?
We implement strict furnace number management and quality traceability for each batch of high-alumina bricks. From raw material storage to finished product shipment, quality control points are implemented at every stage of the process. We can provide detailed batch inspection reports, including key data such as Al₂O₃ content, bulk density, apparent porosity, and room-temperature compressive strength, to ensure that the performance of each brick meets the contractual standards.
How do you provide a customized wear and erosion resistance solution for our specific cement rotary kiln?
We’ll first ask you to provide your kiln operating parameters, including maximum temperature, clinker type, and kiln atmosphere. Based on this data, our technical team will recommend the most suitable high-alumina phosphate bricks or magnesia-chrome bricks and provide optimized brick design recommendations to maximize resistance to chemical attack from the clinker and mechanical wear from the kiln’s rotation.
How do you evaluate the thermal conductivity and shrinkage resistance of ceramic fiber modules in actual use?
When evaluating, please request a thermal conductivity curve and permanent linear shrinkage data from the supplier. The thermal conductivity curve should clearly demonstrate performance changes at different temperatures. Also, please provide actual application examples and compare shrinkage after long-term high-temperature operation. Professional suppliers will provide detailed installation instructions and thermal calculations to ensure effective insulation.
When purchasing monolithic refractory materials in bulk, how can we ensure that the setting time during construction meets the required requirements?
We provide detailed construction instructions and technical guidance. Before shipping, we will adjust the formula based on your construction conditions (such as ambient temperature and construction method). During on-site construction, we can dispatch technicians to provide guidance, ensuring the correct amount of water added. We also use specialized equipment such as rheometers to ensure that the castable’s fluidity and setting time meet construction requirements, thus avoiding quality issues caused by improper construction.
How can you help us control the total cost of refractory materials for large-scale projects?
We can help you optimize costs in the following ways: First, we will optimize the material solution based on your specific project needs, recommending the most cost-effective product combination and avoiding unnecessary excess performance. Second, for large-volume orders, we offer competitive volume discounts. Finally, by providing professional construction guidance and on-site technical support, we can reduce material waste and rework costs caused by improper construction, thereby reducing your overall project cost.
Can we customize refractory bricks for non-standard sizes or shapes? How can we guarantee delivery times?
Yes, we fully support customizing refractory bricks for non-standard sizes and shapes. Simply provide detailed design drawings and technical specifications. We will use advanced CNC equipment for precision machining to ensure accurate brick dimensions. Regarding delivery times, we will incorporate your custom order into a dedicated production schedule and schedule it with you in advance to ensure on-time delivery without impacting project schedules.
If we establish a long-term partnership with your company, besides preferential pricing, what additional services will you receive?
With a long-term partnership, the services we provide you will far exceed the price alone. You will receive:
- Dedicated Account Manager Service: Provides one-on-one, fast response and professional support.
- Inventory and Stocking Services: We can provide inventory stocking solutions based on your annual usage, ensuring you can quickly access your products at any time without worrying about raw material shortages.
