Customization requirements of refractory castable:
I. Product specifications and performance requirements
(1) Chemical composition
Alumina (Al₂O₃) content: ≥[X]%, so as to ensure that the material has sufficient fire resistance and chemical stability, and meet the requirements of high temperature environment and possible chemical erosion in the project.
Calcium oxide (CaO) content: ≤[X]%, which reduces the risk of high-temperature performance degradation of materials caused by too high calcium content.
Other components: please adjust according to the detailed chemical composition table provided by our company, strictly control the impurity content and ensure the purity of the material.
(2) Physical properties
Bulk density: ≥ [x] g/cm (110 C× 24h), ensuring the compactness of the material, thus improving its wear resistance and erosion resistance.
Compressive strength at room temperature:
110°C×24h：≥[X] MPa
[x] c× 3h: ≥ [x] MPa (select the appropriate test temperature according to the actual use temperature range, such as 1350°C, 1500°C, etc.).
Normal temperature flexural strength:
110°C×24h：≥[X] MPa
[X]°C×3h：≥[X] MPa
Linear change rate: [x] c× 3h, ≤ [x]%, which ensures good dimensional stability of the material in high temperature environment and avoids structural damage caused by thermal expansion or contraction.
Wear resistance: Tested according to ASTM C-704 standard, the wear amount is ≤ [x] cm, so as to meet the wear resistance requirements under high temperature, high-speed airflow or material scouring environment in the project.
Thermal conductivity: at [x] C, the thermal conductivity shall be ≤ [x ≤[X] W/m·K, which shall be customized according to actual requirements to achieve good thermal insulation effect or meet specific heat transfer requirements.
Thermal shock stability: after [X] times of thermal shock ([x] C water cooling), it will not crack or peel off, which is suitable for the working conditions with frequent temperature fluctuations in the project.
II. Construction performance requirements
Fluidity: The material should have good fluidity, and it can be smoothly formed in the construction site by pouring, vibrating or ramming, filling all corners of the formwork, and achieving ideal construction effect without adding additional additives.
Setting time: the initial setting time is ≥[X] hours, and the final setting time is ≤[X] hours, so as to ensure that the construction operation has enough time, and at the same time, ensure that the material has a certain strength within a reasonable time, which is convenient for the subsequent construction process.
Expansibility: During the construction process and after hardening, the material should have appropriate expansibility to compensate the shrinkage at high temperature, ensure close combination with surrounding structures and avoid cracks.
III. Packaging and Transportation Requirements
Packaging: [specific packaging method, such as 25kg plastic woven bag or kraft paper bag] is adopted, lined with moisture-proof film, to ensure that the materials are protected from moisture and pollution during transportation and storage. Each bag should be accompanied by product certification, production date, batch number and other identification information.
Transportation: Rain-proof, sun-proof and moisture-proof measures should be taken during transportation to avoid the materials from caking due to moisture. The means of transport shall be clean and dry, and shall not be mixed with acid, alkali, oil and other substances.
IV. Quality Control and Inspection
Your company needs to provide detailed product quality control system documents, including operation procedures and records of raw material procurement inspection, production process monitoring and finished product inspection.
Before leaving the factory, each batch of products should be sampled and inspected according to the inspection standards provided by our company, and complete inspection reports should be provided, including chemical composition analysis and physical performance test results.
Our company has the right to re-examine the goods after receiving them. If quality problems are found, you need to deal with them within [X] working days and bear all the expenses and losses arising therefrom.
V. Delivery Date and After-sales Service
Delivery date: production and delivery shall be completed within [X] days from the date of signing the contract, and the specific delivery date shall be subject to our written notice.
After-sales service: Your company should provide a quality guarantee period of at least [X] years.
