Product Advantages(1) Customizable Furnace Temperature Curve: The firing furnace is designed with multi-zone temperature controls and adjustments, allowing flexible setting of temperature curves.This accommodates diverse requirements for different workpieces, glazes, and specific areas of the same workpiece during enamel firing.By configuring distinct temperature profiles, each workpiece achieves optimal firing results. For components with varying requirements, PLC controls temperature and dwell time independently.The enamel furnace uses a rational heating element layout and temperature curve control, achieving temperature uniformity ≤±5℃. This ensures consistent enamel quality across different parts within the same batch and prevents enamel discoloration caused by localized over-firing. (2) High Efficient Energy Saving and Environmental Protection: TIMS's enamel firing furnaces utilize high-temperature insulation wool, nano-insulation materials and waste heat recovery systems.These are integrated with TIMS's patented technologies (Powder Coating Line Exhaust Heat Recovery System CN ZL 202222652871.4, System for Utilizing Waste Heat from Enamel Kiln Roofs CN ZL 202320531560.4; Secondary Utilization System for Kiln Exhaust Waste Heat CN ZL 202423315073.8), reducing heat loss by 40% compared to conventional equipment and achieving a 40% reduction in energy consumption for enamel production lines. The waste heat collection and recycling system minimizes structural damage to equipment and electrical control systems caused by heat dissipation, enhances operational safety, and extends equipment lifespan. It reduces emissions and lowers operational costs, achieving environmentally friendly, energy-efficient, green production with low consumption and high efficiency.6. Product Advantages (1) Innovative Anti-Part-Drop Mechanism Design:Through patented technology (a protective enamel furnace for heating systems, Patent No.: CN ZL 202022244902.3), the structural optimization of the enamel furnace achieves protection for its internal heating elements, preventing impact damage caused by dropped cores. (2) Dual Excellence in Safety and Durability, Reducing Operational Costs: Gas models feature triple safety protection—a flame detector, over-pressure relief valve and leak alarm—automatically shutting off gas supply within 1 second of flame failure. Electric models utilize dry-burn resistant heating tubes (310S stainless steel, withstands 1200°C temperatures). The furnace surface incorporates a heat-resistant design (temperature ≤ ambient temperature + 5°C) to prevent operator burns. Core components—radiation tubes (Alloy 601 material)—have a service life ≥5 years, while heating tubes last ≥3 years. The average daily failure rate is ≤0.05%, minimizing downtime and repair losses. (3) Smart Operations & Maintenance with Data Traceability for Modern Production: Equipped with a Plant Health Management (PHM) system that continuously monitors radiation tube/heating tube temperatures, furnace door seal integrity, and fan operating parameters, providing 15-30 days advance warning of potential failures (e.g., radiation tube aging, heating tube power degradation); Supports integration with factory MES systems to automatically record firing temperature curves, duration, and energy consumption data for each batch of workpieces (stored for ≥1 year). Accessible via touchscreen or mobile app, it meets quality traceability and production management requirements.7. Product Composition(1) Furnace Structure: a.

This ensures strong adhesion and high gloss of the enamel layer, free from defects such as pinholes and orange peel, meeting the enamel quality requirements for various workpieces.Energy Consumption and Safety ManagementMinimizes energy consumption through designs such as waste heat recovery, zone heating, and intelligent power cutoff ect. Equipped with multiple safety protection devices that monitor risks like gas leaks, abnormal temperatures, and equipment failures in real time, ensuring safe and stable operation while preventing accidents.Data Traceability and OperationsAutomatically records firing parameters (temperature, time, energy consumption) for each batch of workpieces, supporting data export and query to meet quality traceability requirements. The equipment health management system provides early warnings for potential failures and offers remote operations support, reducing downtime and enhancing overall equipment effectiveness (OEE ≥ 95%).Product features(1) Specialized Design: Heating methods and temperature zone layouts are customized for the specific characteristics of the enamel firing process.For instance, indirect heating via radiant tubes prevents direct flame contact with workpieces (avoiding enamel discoloration), while multi-temperature zone design accommodates the entire "preheating - melting - curing" process, addressing the common issue of traditional industrial furnaces being "highly versatile but lacking specialization." This makes it the dedicated equipment for enamel firing and processing.(2) Flexible Adaptability: Supports both continuous and intermittent operation modes. Continuous mode accommodates high-volume standardized workpieces (e.g., water heater liners, oven liners), while intermittent mode suits low-volume customized workpieces (e.g., irregularly shaped enameled parts). Furnace length and chamber volume can be customized to meet diverse production capacity and workpiece specification requirements.(3) Easy Operation and Maintenance: Equipped with a graphical touchscreen interface and pre-set process templates for specific workpieces (e.g., 60L water heater tanks, built-in oven panels), new operators can achieve independent operation after just 2 hours of training. Core components (e.g., burners, radiant tubes) feature a modular design, enabling replacement within ≤1.5 hours. The equipment maintains a daily average failure rate of ≤0.05%, minimizing downtime losses. Supports remote maintenance and debugging.(4) Intelligent Monitoring:TIMS's automated, intelligent, and information-driven enamel production line utilizes PLCs and touchscreens to display and monitor real-time data including conveyor speed, furnace temperature, various pressures, production capacity, and safety parameters. Abnormal conditions (such as temperature overshoot or insufficient coating) trigger audible and visual alarms while simultaneously recording maintenance cycles for core components (burners, radiant tubes).(5) High Efficiency and Low Consumption:TIMS's enamel production line features automation, intelligence, and informatization. Its fully automated design shortens the design cycle, while meticulous organization and implementation by experienced workers reduce production and installation/commissioning time. Automated, minimally staffed, or unmanned production, efficient energy conversion, waste heat recovery, and coating recycling enable TIMS's enamel production line to achieve low energy consumption, low labor costs, and high material recovery rates.(6) High Configuration and Quality Stability: TIMS's high-end enamel furnaces feature core components—including radiation tube materials and electrical control components—imported from Europe. They deliver stable performance and extended service life, ensuring consistent production and high output from the enamel furnaces.(7) Superior Enamel Quality: The high-temperature firing furnace achieves temperature control accuracy of ±3°C, delivering exceptional firing quality. The resulting enamel layer is uniformly smooth, impact-resistant, and exhibits outstanding acid and alkali resistance, with adhesion ≥5 N/cm (compliant with ASTM D3359 standard).Company ProfileABOUT USTIMS Group Company was founded in 2003.
