As a core piece of equipment for automated material feeding and equipment repair, the feeding and patching machine is applied in various industrial scenarios—from high-temperature hot patching of converter linings to the precise delivery of chemical raw materials. With its mechanized and intelligent features, it is gradually replacing the traditional manual operation mode and has become a core engine for improving production efficiency.

Manual feeding and patching are limited by human physiological boundaries, resulting in obvious efficiency bottlenecks and intermittent cycles. Taking converter lining repair as an example, manual delivery of material bags requires the coordination of multiple workers. Affected by the high-temperature environment, the duration of a single manual operation is usually no more than 20 minutes, and the effective daily repair time is less than 4 hours. In contrast, the hot patching and feeding machine for converter linings accelerates the ejection of material bags through the relative movement of upper and lower conveyor belts, enabling 24/7 continuous operation. The daily repair efficiency of a single machine is equivalent to that of 8 skilled workers.

In large-scale production scenarios, this efficiency gap is even more significant. The minimum patching capacity of a semi-dry spray patching machine reaches 250 kilograms per hour, with a continuous and stable material flow. Its efficiency is more than 5 times higher than that of manual spraying, shortening the repair time of large industrial furnaces from 3 days to 8 hours. The data in the agricultural field is also impressive: a fully automatic feeding machine can achieve a feeding capacity of 25 tons per hour, which is 12 times more efficient than manual feeding, meeting the large-scale needs of medium-sized breeding farms.

The precision of manual feeding and patching is highly dependent on the skills and experience of operators, and is easily affected by factors such as fatigue and mood, leading to material waste or unstable operation quality.

In industrial repair scenarios, precision differences directly determine the operation effect. When manually repairing key parts such as converter trunnions and molten pools, the deviation of material bag delivery often exceeds 30 centimeters, resulting in incomplete repair and a reduction of more than 20% in the service life of the furnace lining. On the other hand, the feeding and patching machine can achieve precise operations with a delivery position error of less than 5 centimeters by adjusting the conveyor belt speed, traveling wheel positioning, and compressed air pressure. This allows the repair material to form a solid carbon-bonded layer, extending the service life of the furnace lining by 30%.

Manual feeding and patching are accompanied by extremely high safety risks in many scenarios. In the metallurgical industry, the temperature at the converter repair site can reach over 600°C. Manual material feeding requires facing the risks of high-temperature radiation and splashing material bags, with an annual work-related injury rate of 3.2‰ due to operation accidents. In the chemical industry, manual material feeding involves contact with toxic and harmful dust, which is likely to cause occupational diseases after long-term exposure.

The feeding and patching machine has completely changed this situation through multiple safety designs. The hot patching and feeding machine for converters is equipped with a fire shield and side shields, which can effectively isolate heat sources and prevent material bags from falling. This safety upgrade not only protects the rights and interests of workers but also reduces the losses of enterprises caused by safety accidents.

The initial equipment cost of the feeding and patching machine is relatively low, and its whole-life cycle cost is far lower than that of manual feeding and patching.

The replacement of manual feeding and patching by the feeding and patching machine is essentially a transformation of the production method from "experience-driven" to "technology-driven". Its multi-dimensional breakthroughs in efficiency, precision, safety, and cost not only directly improve the production efficiency of enterprises but also promote the standardization and intelligent upgrading of the manufacturing and agricultural industries. With the in-depth integration of technologies such as the Internet of Things (IoT) and Artificial Intelligence (AI), the feeding and patching machine will no longer be an isolated production equipment but a key node in the ecosystem of smart factories and smart agriculture, injecting sustained impetus into the high-quality development of industries.
