Application of customized muffle furnace in the ceramic industry

In the ceramic industry, customized muffle furnaces have become the core equipment for improving product quality, reducing production costs, and promoting technological innovation through material adaptation, process optimization, energy conservation and environmental protection, and intelligent integration. Their applications run through the entire chain from traditional ceramic production to new material research and development. The following is an analysis of specific application scenarios and technological advantages:

1. Traditional ceramic firing: dual improvement of efficiency and quality
Rapid temperature rise and fall and energy conservation and consumption reduction
Requirement: Traditional ceramics (such as daily-use ceramics and architectural ceramics) need to be fired at 1200 ℃~1400 ℃. Traditional refractory brick furnaces have slow heating (usually taking 4-6 hours) and high energy consumption (accounting for more than 30% of production costs).
Customized solution:
Ceramic fiber furnace: made of alumina fiber or mullite fiber material, with a thermal conductivity of only 1/5~1/10 of traditional refractory bricks, the heating rate is increased to 10-20 ℃/min, and the heating time is shortened by 30%~50%.
Intelligent temperature control system: PID algorithm controls temperature fluctuations within ± 1 ℃, reducing the surface temperature of the furnace to below 50 ℃ (traditional furnaces often exceed 100 ℃), and reducing energy consumption by 40% to 60%. Taking an annual production of 100000 ceramic products as an example, the annual electricity cost savings are about 150000 to 200000 yuan.
Case: After a ceramic enterprise customized a 1200 ℃ ceramic fiber muffle furnace, the firing cycle was shortened from 8 hours to 5 hours, resulting in a 15% increase in yield and a 45% decrease in energy consumption per unit product.
Temperature uniformity and product stability
Requirement: In ceramic firing, a local temperature difference exceeding 10 ℃ can easily lead to cracking, deformation, or uneven glaze surface.
Customized solution:
Multi stage heating element layout: silicon molybdenum rods or silicon carbon rods are evenly arranged, combined with an intelligent temperature control system, to achieve temperature uniformity within ± 5 ℃ in the furnace.
Rapid cooling technology: Water cooling+nitrogen blowing system achieves a cooling rate of 100 ℃/min, suppresses excessive grain growth, improves product density (over 98%) and mechanical properties (compressive strength increased by 10%~15%).
Case: After a certain art ceramic factory customized equipment, the brightness and layering of glaze colors significantly improved, and the order volume of high-end products increased by 30%.

2. Research and development of special ceramics: breakthroughs in high-temperature performance and atmosphere control
Silicon nitride ceramic sintering

3. Recycling of Waste Ceramics: Resource Recycling and Cost Optimization
Thermal decomposition of ceramic waste
Requirement: Waste ceramics need to be pyrolyzed at 800 ℃~1000 ℃ to remove organic matter, as traditional equipment can easily lead to material cross contamination.
Customized solution:
Modular furnace design: can quickly replace furnace linings of different materials to meet various waste disposal needs.
Exhaust gas treatment system: cyclone dust removal+wet desulfurization device, ensuring that the dioxin emission concentration is less than 0.1ng-TEQ/m ³ (far below the national standard of 1.0ng-TEQ/m ³).
Case: After a recycling enterprise customized equipment, the purity of waste treatment was increased to 99.5%, the valuable metal recovery rate was greater than 95%, and the annual profit increased by 18 million yuan.

4. Intelligent upgrade: synergy between production efficiency and process iteration
Automated production line integration
