In the current era of increasing demand for building safety, fireproof board, as an important building fireproof material, has attracted much attention for its production quality and efficiency. The automatic metering supporting fireproof board production line, with high-precision metering technology and automated production processes, has become a key equipment to ensure the stable quality of fireproof boards and improve production efficiency. This production line deeply integrates the automatic metering system into various stages of fireproof board production, achieving precise raw material ratio and efficient control of the production process, promoting the fireproof board manufacturing industry to move towards intelligence and standardization.

1、 System architecture of automatic metering matching fireproof board production line

（1） Core components of automatic metering system

Material measurement unit: The production line is equipped with high-precision weighing sensors and flow sensors to accurately measure various raw materials required for the production of fireproof boards, such as cement, fly ash, fibers, additives, etc. The accuracy of the weighing sensor can reach ± 0.1%, ensuring the precise weight of powdered and granular materials; Flow sensors monitor and control the real-time flow of liquid additives to ensure the accuracy of raw material ratios.

Ingredient control system: With a programmable logic controller (PLC) as the core and a human-machine interface (HMI), operators can preset production formulas on the HMI. The system automatically controls the start stop and running speed of various material conveying equipment (such as screw conveyors and belt scales) according to the formula instructions, achieving sequential batching and precise feeding of multiple materials.

（2） Fireproof board production process unit

Mixing unit: The measured material enters a powerful mixer, and through specially designed mixing blades, various raw materials are uniformly mixed in a short period of time. For different formulations of fireproof boards, the mixer can adjust the mixing speed and time to ensure the uniformity of the mixed materials, laying the foundation for subsequent molding.

Forming and pressing unit: The mixed material is conveyed to the forming machine by a conveyor belt, and is formed into a fireproof slab body with specific specifications and densities through mold pressing or roll forming. The forming machine is equipped with pressure sensors and displacement sensors to monitor the pressing pressure and slab thickness in real time, ensuring the dimensional accuracy and physical stability of the slab.

Maintenance processing unit: The formed slab enters the maintenance kiln, and by controlling the temperature, humidity, and maintenance time, physical and chemical reactions occur inside the fireproof board, improving the strength and fire resistance of the board. During the maintenance process, temperature and humidity sensors provide real-time feedback data, and the control system automatically adjusts maintenance parameters to ensure the effectiveness of the maintenance.

Cutting and processing unit: The cured fireproof board is processed into finished products that meet market demand through processes such as fixed length cutting and surface polishing. The cutting equipment adopts CNC technology, combined with laser positioning system, to achieve cutting size error control within ± 1mm, meeting the requirements of different building scenarios.

2、 The core function of the automatic metering matching fireproof board production line

（1） Accurate measurement and intelligent batching

The automatic metering system can store various fireproof board production formulas, covering product formulas with different fire protection levels and strength requirements. In the production process, the system automatically completes the precise measurement and proportioning of all raw materials based on the selected formula. Compared with traditional manual batching, the error rate is reduced by more than 80%, effectively avoiding product quality problems caused by improper raw material proportioning. At the same time, the system has an automatic calibration function to regularly calibrate the accuracy of measuring equipment, ensuring long-term stable operation.

（2） Automated production control

The entire production line achieves full process automation control from raw material measurement, mixing, molding, curing, and cutting. The PLC control system coordinates the operation rhythm of various devices, monitors production data in real time (such as material flow, equipment operation status, product quality parameters, etc.), and when abnormal situations occur (such as material blockage, abnormal pressure), the system immediately issues an alarm and automatically shuts down to ensure production safety. In addition, the production line can also be integrated with the factory's production management system (MES) to achieve real-time uploading and remote monitoring of production data, making it easier for managers to make production scheduling and decisions.

（3） Quality traceability and management

The production line records and stores detailed production data for each batch of fireproof boards, including raw material batches, formula parameters, production time, operators, etc. Through product coding, the entire production process information of the product can be quickly traced. Once a quality problem occurs, the problem link can be quickly located, which facilitates the analysis of the cause and improvement of the process by the enterprise. At the same time, it also provides strong data support for after-sales service.

3、 The application advantages of automatic metering matching fireproof board production line

（1） Improve product quality stability

Accurate raw material measurement and strict production process control ensure that the density, strength, fire resistance and other indicators of each fireproof board meet the standard requirements, and the product qualification rate is increased to over 98%. Taking a large building materials enterprise as an example, after introducing this production line, the customer complaint rate caused by quality problems decreased by 70%, effectively improving the brand reputation of the enterprise.

（2） Improve production efficiency and reduce costs

Automated production reduces manual intervention, and the production line can operate continuously for 24 hours, increasing production efficiency by more than 50% compared to traditional production lines. At the same time, precise measurement avoids raw material waste, reducing the raw material loss rate by 15% -20%; Automated control reduces equipment downtime and significantly lowers overall production costs.

（3） Meet diversified production needs

The powerful formula management function of the system can quickly switch the production of different types of fireproof boards, meeting the market's demand for diversified and customized fireproof boards. Whether it is A-level fireproof board used for high-rise buildings or decorative fireproof board suitable for indoor decoration, the production line can flexibly adjust production parameters and quickly respond to market changes.

The automatic metering supporting fireproof board production line has become an important force in promoting the upgrading of fireproof board manufacturing industry with its advanced technical architecture and excellent functional advantages. With the continuous advancement of technology, this production line will develop towards a more intelligent and efficient direction, providing more reliable guarantees for building safety.
