The main components of automatic refractory material batching include speed regulating feeding device, automatic weighing device, automatic control system, etc. Adjustable feeding devices mainly adopt multi-stroke pneumatic arc valve, variable frequency vibrating feeder and variable frequency spiral feeder, etc. These devices can realize fast and slow feeding according to the batching situation, thus realizing the accuracy of batching. In addition, a quick cut-off valve must be set below the feeding device, which can be closed in time after feeding is completed to ensure the accuracy of each weighing. The reliability and stability of the cut-off valve directly affect the batching accuracy.

$Automatic Batching of Refractory Materials$

　　Automatic weighing devices are divided into mobile and fixed types. Currently, mobile automatic weighing devices, namely mobile batching cars, are widely used. During operation, the batching car automatically moves to the position under the linear silo according to the formula requirements, automatically finds its position under the silo for automatic batching, adds materials from different feeding points to the weighing hopper for batching, and automatically discharges at a fixed discharge position. Accurate positioning within 50px can be achieved using on-site photoelectric switch positioning and stopping. The metering hopper uses high-precision sensors and intelligent instruments, and has an intelligent control function for weight setting. When setting the metering value, it has three functions: coarse feeding, medium-speed feeding, and fine feeding, which can effectively control automatic feeding.

　　Automatic batching of refractory materials is generally composed of an industrial computer and a series of PLCs. The industrial computer uses configuration software to schedule, manage, and display the entire system. The monitoring software can dynamically display the process flow of the entire production process, the operation, faults, and alarm status of each equipment, and process parameters such as silo high and low levels and valve opening and closing. Multiple PLCs are used as lower-level controllers to achieve real-time control of the batching process, and the upper and lower level controllers communicate using fieldbus or industrial Ethernet.

　　Main Functional Characteristics of High-Quality Automatic Batching of Refractory Materials

　　Automatic batching of refractory materials avoids the instability and untraceability of manual batching operations, has out-of-tolerance alarm and error correction functions, and can effectively ensure the accurate implementation of the formula and the stability of product quality. The control system can store multiple formulas, and batching can be adjusted and changed at any time according to production needs, improving production efficiency. Moreover, formula names can be replaced with codes, which facilitates the confidentiality of company formulas. Automatic batching of refractory materials can also record and print the results of each batch, print daily and monthly reports, which greatly facilitates production statistics.

　The powerful reporting function of automatic batching of refractory materials can record and store a large amount of data and generate tables and printouts. It automatically prints batching reports after each production, providing the date, time, report number, and the actual consumption of each material; using PC manual query method, the production completion report is stored in the computer, and can be read infinitely, ensuring correctness and integrity.
