FAQ

Q1: How do you control the products quality?

A1: With strict quality control system throughout the materials selection and production process, our refractory and ceramic fiber products quality is effectively controlled to meet customer requirements.

From the raw materials selecting, our quality control begin. The quality certificates of raw materials are required and each batch will be tested before using. During production, the quality control are conducted by workers and then each piece will be sorted and examined by quality supervis

 

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.


Q:
Insulating fire bricks are a suitable choice for kilns and furnaces, offering excellent thermal insulation that is ideal for applications requiring high temperatures. These bricks are specifically designed to provide outstanding thermal insulation, making them perfect for kilns and furnaces. With their low thermal conductivity, they effectively minimize heat loss, thereby enhancing energy efficiency. Furthermore, their lightweight and durable nature allows for easy installation and long-lasting performance in high-temperature environments. Not only are they resistant to thermal shock, but they also withstand rapid temperature changes, making them a reliable option for kilns and furnaces. Overall, insulating fire bricks are an exceptional choice for insulation and the maintenance of high temperatures in kilns and furnaces.
Q:Clay insulation bricks insulation, brick and ordinary clay brick, fireclay, brick distinction, and its use? Thank you
The contrast between the two should not be much different, the insulation brick in the masonry wall at the same time, will be good insulation effect into the wall.
Q:What are the new types of building brick materials?
The whole material made of brick and mortar is one of the most widely used building materials. According to whether the masonry is reinforced, it is divided into unreinforced brick masonry and reinforced brick masonry.
Q:
Yes, insulating fire bricks can be used in the construction of crucibles. These bricks are designed to withstand high temperatures and provide excellent insulation, making them suitable for use in crucibles where extreme heat is required.
Q:
Insulating fire bricks prove to be a suitable option for constructing incinerators. They are specifically designed to endure high temperatures and possess exceptional insulation properties. Incinerators operate at extremely high temperatures, often surpassing 1000 degrees Celsius, and require materials that can withstand such intense conditions without cracking or deteriorating. Made from lightweight refractory materials like ceramic fibers or lightweight aggregates, insulating fire bricks possess low thermal conductivity. Consequently, they effectively insulate the incinerator, preventing heat escape and maximizing energy efficiency. Moreover, the insulation properties of these bricks aid in maintaining a consistent temperature inside the incinerator, which is crucial for proper combustion and waste disposal. Furthermore, insulating fire bricks exhibit remarkable resistance to thermal shock, enabling them to withstand repeated cycles of heating and cooling without sustaining damage. This attribute is particularly vital in incinerators, where the temperature can rapidly fluctuate during the burning process. The bricks' capacity to endure thermal shock guarantees their durability and longevity in this high-temperature environment. Apart from their insulation and thermal shock resistance, insulating fire bricks offer additional advantages for incinerator construction. They possess a lightweight nature, facilitating easier handling and transportation during the construction phase. Furthermore, they can be readily cut or shaped to fit specific designs or requirements, allowing for flexibility in incinerator construction. In conclusion, insulating fire bricks stand as an ideal choice for incinerator construction due to their resistance to high temperatures, insulation properties, thermal shock resistance, durability, and ease of use. They provide a reliable and efficient solution for containing and maintaining the intense heat generated in incinerators, ensuring the safe and effective disposal of waste.
Q:
Yes, insulating fire bricks can be used in ceramic fiber boards as they provide thermal insulation and enhance the overall insulation properties of the boards.
Q:
Yes, insulating fire bricks can be used in the construction of hearths. These bricks are designed to withstand high temperatures and provide excellent insulation, making them ideal for use in hearth construction. They help to retain heat and prevent the loss of energy, ensuring efficient and effective heating.
Q:
Yes, insulating fire bricks can be used for insulation in smelters. Insulating fire bricks are specifically designed to withstand high temperatures and provide excellent thermal insulation. They are made from lightweight refractory materials that have low thermal conductivity, allowing them to effectively retain heat and minimize heat loss. This makes them ideal for use in smelters, where maintaining high temperatures is crucial for efficient metal smelting processes. Additionally, insulating fire bricks are resistant to chemical attack and mechanical stress, ensuring their durability and suitability for use in harsh smelting environments.
Q:
Yes, insulating fire bricks can be cut to size using various cutting tools such as saws or knives.
Q:
There are several different types of insulating fire bricks available, each with their own unique characteristics and applications. Some of the most common types include: 1. Lightweight Insulating Fire Bricks (IFBs): These bricks are made from lightweight materials, such as expanded clay, perlite, or vermiculite, which are blended with a binder to form a porous structure. They have excellent insulation properties and are commonly used in applications where high temperatures need to be maintained, such as in kilns or furnaces. 2. Mullite Insulating Fire Bricks: Mullite bricks are made from a combination of alumina and silica, resulting in a high-temperature resistant material. These bricks have excellent thermal shock resistance and are often used in applications where rapid heating and cooling cycles are involved, such as in glass manufacturing or incinerators. 3. Alumina Insulating Fire Bricks: As the name suggests, these bricks are made primarily from alumina, a high-temperature resistant material. They have excellent thermal conductivity and are often used in applications where high temperatures need to be maintained, such as in the iron and steel industry or in the production of ceramics. 4. Silica Insulating Fire Bricks: Silica bricks are made primarily from silica, a heat-resistant material. They have excellent thermal insulation properties and are often used in applications where high temperatures need to be maintained, such as in the construction of kilns or furnaces. 5. Calcium Silicate Insulating Fire Bricks: These bricks are made from a combination of calcium silicate and other insulating materials. They have excellent thermal insulation properties and are often used in applications where high temperatures need to be maintained, such as in the petrochemical industry or in power plants. Overall, the choice of insulating fire brick depends on the specific requirements of the application, including temperature resistance, thermal conductivity, and thermal shock resistance. It is important to select the appropriate type of insulating fire brick to ensure optimal performance and safety.
