What Performance Stability Can UHPC Manufacturers' Automated Production Lines Improve? Smart Manufacturing and Qinglong Group's Production Innovation

The UHPC automated production line, through innovation across four stages—"precise batching, high-efficiency mixing, mechanical forming, and intelligent curing"—reduces the fluctuation of key product indicators to below 3%. Qinglong Group's Nanning production base has introduced the German M-TEC robotic spraying system, achieving fiber distribution uniformity ≥95%, strength coefficient of variation ≤5%, and thickness tolerance of ±0.5mm. Compared with traditional manual production, the automated line increases production efficiency by 300% and raises the product pass rate from 92% to 99.5%. Intelligent production is the fundamental guarantee of quality stability.

Precise Batching System Eliminates Human Error

The automatic weighing system achieves a precision of ±0.5%, reducing errors by 80% compared with manual feeding. An online sand moisture content monitoring device adjusts water volume in real time, keeping water-binder ratio fluctuation within ±0.01. Qinglong's central control room can simultaneously monitor the ratios of 16 raw materials, ensuring a consistent formula for every batch.

Robotic Spraying Delivers a Process Revolution

The six-axis robotic arm sprays the slurry along a preset path, with spraying pressure stable at 0.4-0.6MPa, achieving a three-dimensional random distribution of 12mm-long steel fibers. In the production of double-curved panels for the Wuhan Han Show Theatre, the robot perfectly replicated 0.5mm-deep embossed textures, replacing traditional manual application.

Intelligent Curing System Enhances Material Performance

The steam curing kilns use zone-based temperature control (temperature difference ≤2℃), with programmed heating and cooling rates to prevent thermal stress cracking. Curing curve data is uploaded to the cloud in real time and linked with the strength development model. Compared with natural curing, steam curing increases 7-day strength by 50%.

Full-Process Data Traceability Ensures Consistency

Each panel is embedded with an RFID chip recording 200+ parameters from batching to curing. The big data analysis system provides early warning of abnormal fluctuations—for example, the machine stops automatically if fiber dosage deviation is found to be ≥0.1%. Customers can query full life-cycle data via a QR code.

Automation is not a simple replacement of manual labor, but a systematic upgrade of quality control. Through smart factory construction, Qinglong Group provides customers with UHPC products of aerospace-grade precision.
