Share:
In the field of industrial furnace insulation materials, whether traditional refractory materials can be replaced is a core issue of concern for many enterprises. For a long time, traditional materials such as refractory bricks and castables have dominated the market with mature application scenarios. However, with the increasing demand for energy conservation, efficiency, and cost control in industrial production, their limitations have become increasingly apparent. As a benchmark enterprise in the insulation and refractory materials industry, Rosewool has proven through technological research and market practice that ceramic fiber modules can not only replace traditional refractory materials, but also achieve comprehensive upgrades in performance, cost, construction, and other aspects, bringing higher value to enterprises. ​
                                          

  • Breaking first and then standing up: the increasing necessity of replacing traditional refractory materials

To determine whether ceramic fiber modules can replace traditional refractory materials, it is necessary to first understand the "unsustainability" of traditional materials. In the current context of industrial green transformation and cost reduction and efficiency improvement, the three major shortcomings of traditional refractory materials have become obstacles to the development of enterprises. ​

One is serious energy waste and high operating costs. The thermal conductivity of traditional refractory bricks is generally between 0.6-1.0W/(m · K). During the operation of industrial furnaces, a large amount of heat leaks through the furnace wall, and enterprises need to continuously consume more coal or electricity to maintain the temperature inside the furnace. Taking a steel enterprise with an annual output of 100000 tons as an example, its heating furnace uses traditional refractory bricks for insulation, resulting in an annual energy cost of over 2 million yuan due to high heat loss, which becomes a heavy cost burden in the long run. ​

Secondly, the construction and maintenance costs are both high. The construction of traditional refractory materials requires on-site mixing, masonry, and maintenance. The insulation construction of a medium-sized industrial furnace takes 10-15 days, which not only has high labor costs but also leads to long-term downtime of the production line; Moreover, refractory bricks have poor thermal shock resistance and need to be replaced as a whole after 3-5 years. Each maintenance incurs material and downtime losses of hundreds of thousands of yuan, seriously affecting production continuity. ​

The third issue is poor adaptability, making it difficult to meet complex working conditions. With the upgrading of industrial furnace technology and the increase of new equipment such as irregular furnaces and high-temperature special furnaces, traditional refractory materials need to be cut and adjusted on site, which is prone to joint gaps and affects the insulation effect; However, after solidification, the casting material is prone to shrinkage and cracking, and cannot adapt to complex structures such as arcs and holes, which restricts the performance of industrial furnaces. ​
  • Rosewool Ceramic Fiber Module: Three Core Advantages, Building a "Substitute Confidence"

Faced with the shortcomings of traditional refractory materials, Rosewool Ceramic Fiber Module has achieved breakthroughs in performance, cost, and adaptability through technological innovation, becoming an ideal choice to replace traditional materials. Its core advantages are specifically reflected in the following three aspects:

Advantage 1: Combining energy efficiency and durability, reducing long-term operating costs

The primary solution to replacing traditional materials is energy waste. Rosewool Ceramic Fiber Module uses high-purity alumina and silica raw materials, which are melted and fiber-reinforced at high temperatures. The thermal conductivity at room temperature is ≤ 0.038W/(m · K), which is only 1/20 of traditional refractory bricks. It can reduce the heat loss rate of industrial furnaces by more than 30%. After replacing the traditional refractory bricks in the reactor with this module, a certain chemical enterprise reduced its annual electricity consumption from 9 million kWh to 6.3 million kWh. Calculated at an industrial electricity price of 0.6 yuan/kWh, it saves 1.62 million yuan in electricity costs annually and can recover material investment in 2 years. ​

Meanwhile, the durability of the module far exceeds that of traditional materials. It has excellent thermal shock resistance and can withstand drastic temperature changes below 1400 ℃ (from room temperature to 1200 ℃ and then cooled down, repeated 50 times without cracking). It also has strong chemical stability and is not easily corroded by the medium inside the furnace. Through market verification, the service life of Rosewool ceramic fiber modules can reach 8-10 years, which is 2-3 times that of traditional refractory materials. During this period, only 1-2 simple inspections are required per year, greatly reducing maintenance costs and downtime losses. ​

Advantage 2: Lightweight and convenient, reducing construction and structural costs

Traditional refractory materials have a high density (about 2.3g/cm ³ for refractory bricks), and a set of industrial furnace insulation layers can weigh tens of tons, requiring additional reinforcement of the furnace steel structure and increasing structural costs by tens of thousands of yuan; The density of Rosewool ceramic fiber module is only 0.2-0.3g/cm ³, and its weight is 1/8-1/10 of traditional materials, greatly reducing the load on the furnace body and saving the cost of steel structure reinforcement. ​

In terms of construction efficiency, modules achieve a "dimensionality reduction strike". Rosewool adopts a prefabricated production mode and customizes modules according to the size and shape of industrial furnaces. The modules are cut and formed before leaving the factory, and only need to be assembled and installed on site through dedicated anchoring components. 3-5 workers can complete the insulation construction of a set of small and medium-sized industrial furnaces in 2-3 days, which is more than 70% shorter than the 10-15 day construction period of traditional materials, reducing labor costs and downtime losses. In the forging furnace renovation project of a certain machinery manufacturing enterprise, the construction period was reduced from 12 days to 3 days after using this module, and production resumed 9 days ahead of schedule, creating an additional output value of over 5 million yuan. ​

Advantage 3: Customized adaptation, covering complex working conditions across the entire industry

The ability to adapt to industrial furnaces in different industries is the key to determining whether materials can be fully replaced. Rosewool has a professional technical research and development team that can provide personalized solutions for industrial furnace conditions in different industries such as metallurgy, chemical engineering, building materials, and machinery. For high-temperature tunnel kilns, the module density is adjusted to 0.3g/cm ³ to enhance high temperature resistance; Design arc-shaped modules and matching anchoring components for the arc-shaped heating furnace to achieve seamless splicing; For special furnaces with holes, accurately reserve hole positions to avoid on-site cutting losses. ​

Not only that, Rosewool also provides "full process services": from on-site survey and scheme design, to customized production, installation guidance, and after-sales maintenance, with technical personnel following up throughout the process. In the irregular tunnel kiln project of a certain building materials enterprise, the technical team customized 12 different shaped modules through 3 on-site surveys. After installation, the insulation effect reached the standard rate of 100%, the temperature uniformity inside the furnace increased by 15%, and the product qualification rate increased by 8%. ​
