As the "heart" of industrial production, the selection of insulation materials for industrial furnaces directly determines the production efficiency, energy consumption, and operating costs of enterprises. For a long time, traditional refractory materials such as fire-resistant bricks and castables have dominated the market due to their high temperature resistance. However, with the increasing demand for energy saving, high efficiency, and low cost in industrial production, their inherent shortcomings have gradually become prominent. As a leading manufacturer in the field of insulation and refractory materials, Rosewool's ceramic fiber modules are gradually replacing traditional refractory materials with comprehensive performance advantages and becoming the preferred solution for industrial furnace insulation. The pain points of traditional refractory materials are highlighted, which restricts the development of enterprises
Traditional refractory materials have long faced three core challenges in industrial furnace applications. One is high energy consumption and high cost: refractory bricks, castables, and other materials have a high thermal conductivity, which is generally between 0.6-1.0W/(m · K) at room temperature. During the operation of industrial furnaces, heat loss is severe, and enterprises need to invest more energy to maintain the temperature inside the furnace. The additional cost of coal or electricity consumed each year can reach hundreds of thousands of yuan. Secondly, the construction is cumbersome and time-consuming: traditional refractory materials require on-site mixing, masonry, or pouring, which not only requires high technical requirements for construction personnel, but also takes a long time to cure and maintain. A set of medium-sized industrial furnace insulation construction often takes 10-15 days, seriously affecting the production progress of enterprises. Thirdly, the service life is short and maintenance is frequent: refractory bricks have poor thermal shock resistance and are prone to cracking and peeling when subjected to drastic temperature changes. They usually need to be replaced as a whole after 3-5 years; Castable materials are prone to gaps due to shrinkage, leading to heat leakage and requiring regular repairs. Each maintenance is accompanied by downtime losses, further increasing the burden on the enterprise.
Rosewool Ceramic Fiber Module: Four core advantages, comprehensively surpassing traditional materials
Faced with many pain points of traditional refractory materials, Rosewool Ceramic Fiber Module has achieved comprehensive breakthroughs through technological innovation, becoming a "weapon" to solve the insulation problems of industrial furnaces.
Advantage 1: Low consumption and energy saving, significantly reducing operating costs
Energy saving is the most significant advantage of ceramic fiber modules. Rosewool Ceramic Fiber Module adopts high-purity ceramic fiber raw materials, which are compressed and formed through special processes. The thermal conductivity at room temperature is ≤ 0.038W/(m · K), which is only 1/20-1/15 of traditional refractory bricks. It can effectively block the heat transfer from the furnace and reduce the heat loss rate of industrial furnaces by more than 30%. Taking an industrial furnace with an annual operation of 8000 hours and a power of 1000 kW as an example, when using traditional refractory materials, the annual energy consumption is about 8 million kWh; After replacing with Rosewool ceramic fiber modules, the annual energy consumption can be reduced to 5.6 million kWh. Calculated at an industrial electricity price of 0.6 yuan/kWh, the annual electricity cost can be saved by 1.44 million yuan. The material investment cost can be recovered in the short term, and the long-term energy-saving benefits are more significant.
Advantage 2: Lightweight and convenient, reducing construction and structural costs
Traditional refractory bricks have a high density (about 2.3g/cm ³), and the weight of an industrial furnace insulation layer can reach tens of tons. This not only increases the load-bearing pressure of the furnace steel structure, but also requires additional reinforcement of the furnace body, thereby increasing the structural cost. The density of Rosewool ceramic fiber module is only 0.2-0.3g/cm ³, and its weight is only 1/8-1/10 of traditional refractory bricks, greatly reducing the load on the furnace body and reducing the cost of steel structure reinforcement. At the same time, the module adopts prefabricated production, which can be customized according to the size, curvature, holes and other parameters of the industrial furnace. It has been cut and formed before leaving the factory, and only needs to be assembled and installed on site through special anchoring devices. 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 refractory materials, reducing labor costs and downtime losses.
Advantage 3: Durable and damage resistant, extending service life, and reducing maintenance
Traditional refractory materials have poor thermal shock resistance and are prone to cracking and peeling during the start-up and shutdown of industrial furnaces due to sudden temperature increases and decreases, requiring frequent repairs; The Rosewool ceramic fiber module has excellent thermal shock resistance and can withstand drastic temperature changes below 1400 ℃ (from room temperature to 1200 ℃ and then back to room temperature, repeated cycles without cracking). The surface of the module is smooth and dense, and it is not easy to adsorb dust and oil stains, reducing daily cleaning and maintenance workload. Through practical application verification by enterprises in many parts of the country, the service life of Rosewool ceramic fiber module insulation layer can reach 8-10 years, which is 2-3 times that of traditional refractory materials. During this period, only 1-2 simple inspections need to be conducted annually, without the need for large-scale maintenance or replacement, greatly reducing maintenance costs and downtime.
Advantage 4: Customized adaptation to meet diverse working conditions
The working conditions of industrial furnaces in different industries (such as heating furnaces in the metallurgical industry, reaction furnaces in the chemical industry, and tunnel kilns in the building materials industry) vary greatly, and the performance and size requirements for insulation materials are also different. Rosewool has a professional technical research and development team that can provide personalized customization services based on the actual temperature, medium, structure and other parameters of customers' industrial furnaces: from adjusting module thickness and density, to designing special shapes (such as arc and irregular shapes), to customizing supporting anchor components, ensuring perfect compatibility between modules and industrial furnaces, and achieving the best insulation effect. At the same time, the manufacturer provides one-stop services from on-site survey, scheme design to installation guidance, and after-sales maintenance, solving customers' entire process problems from selection to use, so that customers do not have to worry about adaptation and application difficulties.
