FAQ
Q2: What`s the lead time for my order?
A2: It depends on customers’ requirements and our production schedule. And usually we need 30-60 days for refractory bricks,10-25 days for unshaped refractory materials and 10-20 days for ceramic fiber blankets.
Q3: Can you offer Door-to-Door delivery?
A3: Yes, but only for some countries such us U.S., UAE, Saudi Arabia, Iran, and Russia, etc.
- Q: What's the difference between refractory bricks and insulating bricks?
- In the preferred insulation performance, the thermal conductivity of insulating brick insulation brick in general 0.2-0.4 (average temperature 350 - 25 DEG C) w/m.k, and the thermal conductivity of refractory brick in 1 (the average temperature of 350 - 25 DEG C) above w/m.k, which can obtain the insulation performance of insulating brick than refractory brick insulation performance is much better. In the degree of refractoriness, the refractoriness of insulating bricks is generally below 1400 degrees, while the refractoriness of refractory bricks is above 1400 degrees. In density, insulation bricks are generally lightweight insulation materials, the density is generally in 0.8-1.0g/cm3, and the density of refractory bricks are basically above 2.0g/cm3.
- Q: Do insulating fire bricks require a protective coating?
- Insulating fire bricks do not necessarily require a protective coating, as they are already designed to withstand high temperatures and provide insulation. These bricks are made from lightweight refractory materials that have excellent thermal conductivity properties, allowing them to retain heat and prevent heat transfer. However, in some specific applications where the bricks may come into contact with corrosive materials or aggressive chemicals, a protective coating may be necessary to enhance their durability and resistance. Ultimately, the need for a protective coating depends on the specific usage and environment in which the insulating fire bricks are being used.
- Q: Are insulating fire bricks suitable for applications requiring low thermal conductivity?
- Yes, insulating fire bricks are suitable for applications requiring low thermal conductivity. Insulating fire bricks are specifically designed to have low thermal conductivity, making them ideal for situations where heat insulation is necessary. These bricks are made from lightweight and porous materials, such as clay and other refractory materials, which provide excellent insulation properties. The porous structure of insulating fire bricks traps air within the material, reducing heat transfer and resulting in low thermal conductivity. This makes them effective in applications such as kilns, furnaces, and other high-temperature environments where minimizing heat loss is crucial. Overall, insulating fire bricks are a reliable choice for applications that demand low thermal conductivity.
- Q: Can insulating fire bricks be used in carbon black reactors?
