Metal Smelting & Metallurgy

In the metal smelting industry, which is characterized by high temperatures, high pressures, and complex processes, the valves and their accessories of AnyTorK, with their excellent performance and innovative design, are deeply integrated into each production link. They have become the core elements ensuring the efficient, stable, and safe operation of the smelting process and play an irreplaceable and crucial role.

I. Raw Material Pretreatment Stage

Precise Control of Slurry Transportation: When grinding metal ores into slurry and transporting it to subsequent processes, the wear-resistant ball valves and special regulating valves for slurry of AnyTorK are of great importance. The wear-resistant ball valves, with their special cemented carbide balls and valve seats, can resist the erosion and wear caused by hard particles in the slurry and reliably control the on-off of the slurry flow path. The special regulating valves for slurry can precisely adjust the flow rate of the slurry according to the requirements of the ore dressing process, ensuring that the amount of slurry entering processes such as flotation and magnetic separation is stable and meets the process standards. This lays the foundation for the efficiency and stability of subsequent metal extraction, avoiding problems such as poor ore dressing results and equipment idling or overload caused by fluctuations in the slurry flow rate.
Quantitative Addition of Chemical Agents: During the ore pretreatment process, various chemical agents are often added to promote metal separation. The metering pumps of AnyTorK and the supporting corrosion-resistant valves can precisely control the injection amount of agents such as flotation agents and flocculants according to the properties of the ore and the processing volume. Through the automated control system, the valve opening is dynamically adjusted in real time based on the feedback of the slurry composition and processing effect, ensuring the accuracy and timeliness of agent addition, greatly improving the metal recovery rate, reducing agent waste, and enhancing the economy and environmental friendliness of the entire pretreatment process.

II. Smelting Stage

Guarantee of High-temperature Melt Transportation: In the high-temperature smelting furnace, metals are melted into a liquid state. The high-temperature gate valves and special metal butterfly valves of AnyTorK are responsible for transporting the high-temperature melt to subsequent processes such as refining and casting. These valves are made of special alloy materials with high temperature resistance and high strength, which can withstand high temperatures of over 1000°C and the high-pressure impact of the melt. Their sealing structures are specially designed to effectively prevent melt leakage, ensuring stable operation under extreme working conditions and guaranteeing the continuity and safety of high-temperature melt transportation. This avoids safety accidents and production stagnation caused by melt leakage due to valve failures.
Optimal Control of the Combustion System: The smelting process requires a large amount of energy, and the stable operation of the combustion system is crucial. The gas regulating valves and air flow control valves of AnyTorK ensure sufficient and stable combustion by precisely adjusting the mixing ratio of gas and air. According to the real-time feedback of parameters such as the temperature and pressure in the smelting furnace, the automated control system precisely adjusts the valve opening to keep the combustion process in the optimal working condition, improving energy utilization efficiency, reducing fuel consumption, and decreasing the emission of harmful gases. At the same time, it ensures the precise control of the smelting temperature, providing a reliable guarantee for the quality of metal smelting.

III. Refining and Casting Stages

Gas Regulation in the Refining Furnace: During the metal refining process, specific gases need to be introduced into the furnace to remove impurities and adjust the composition. The gas flow regulating valves and check valves of AnyTorK play a key role in this link. The flow regulating valves can precisely control the flow rate of gases such as argon and nitrogen according to the requirements of the refining process, ensuring that the reactions in the furnace proceed at the predetermined pace. The check valves prevent gas backflow, avoiding damage to the gas supply system caused by the backflow of high-temperature and high-pressure gases in the furnace, ensuring the safety and stability of the refining process, and improving the purity and quality of metal refining.
Precise Control of the Casting Process: Casting is a key step in transforming liquid metal into solid products. The electric regulating valves of AnyTorK are installed at the outlet of the casting ladle. Through the automated control system, according to the size, shape of the mold, and the requirements of the casting speed, the outflow amount of the liquid metal is precisely controlled. During the continuous casting process, it ensures that the liquid metal is uniformly and stably injected into the mold, avoiding problems such as flow interruption and uneven flow, ensuring the consistency of the casting quality and the surface finish, increasing the product qualification rate, reducing the scrap rate, and improving the production efficiency of metal smelting enterprises.

IV. Environmental Protection and Safety Systems

Key Control of Waste Gas Treatment: The metal smelting process generates a large amount of waste gas containing dust and harmful gases. The ventilation butterfly valves and special valves for the desulfurization and denitrification systems of AnyTorK undertake the key tasks of flow regulation and on-off control in the waste gas treatment equipment. The ventilation butterfly valves can flexibly adjust the ventilation volume of the waste gas pipeline according to the demand for waste gas treatment, ensuring that the waste gas fully reacts in the treatment equipment. The special valves for the desulfurization and denitrification systems precisely control the injection amount of desulfurizing agents and denitrifying agents and the flow rate of reaction gases, ensuring that the waste gas is discharged up to the standard, reducing environmental pollution, and helping enterprises meet environmental protection regulations.
Emergency Safety Assurance: In the metal smelting workshop, there may be emergencies such as sudden equipment failures and pipeline leaks. The quick cut-off valves of AnyTorK, as the last line of defense for emergency safety assurance, can instantly cut off dangerous media such as high-temperature melt, gas, and toxic and harmful gases in the pipeline, preventing the further expansion of the accident, protecting the lives of personnel and the property safety of the enterprise, and providing a solid guarantee for the safe production of metal smelting enterprises.
