Procedure for Converter Operation
As steel production enters the modern era, the use of efficient and cost-saving technology is increasingly important. The use of converters, an important part of modern steel production, allows companies to produce high-quality steel with greater efficiency. GM Steel and Products LTD is one of the leading steelmakers in the industry and employs the use of converters in its production processes. In order to ensure the efficient and safe operation of converters, GM Steel and Products LTD has established a comprehensive procedure for converter operation.
To ensure the safety of workers and the product itself, operators must be properly trained in the safe operation of a converter. All operators must watch a safety video on proper converter operation and receive an accurate assessment of their skills and understanding of the standard operating procedure prior to beginning operation.
Operators are required to perform daily pre-operation inspections of their converter prior to using it. The inspection starts with a visual inspection of the unit for any signs of damage, debris, or obstruction. The operator must also check the nozzle and check the integrity of the combustion chamber cover. Other safety checks include checking the piping system and checking the presence of sufficient refractory material to protect against erosion and thermal shock.
Once the pre-operation checks are complete, the operator is then required to start ignition procedures. The converter is initially ignited with natural gas and then various other fuel sources are adjusted to achieve proper combustion. The Burn Manifold is adjusted until the converter achieves the desired surface temperature. Once the surface temperature is reached, the converter is ready for operation.
The operator must then make sure all sensors are working properly and all safety systems are in place before proceeding. If at any point during operation any of the safety systems fail, the operator must shut down the converter immediately and not proceed until all safety checks have been conducted.
When transferring liquid material from storage tanks to the converter, the operator is required to wear appropriate safety equipment, including personal protective gear, to prevent any potential exposure to hazardous substances. The operator must carefully control the speed and rate of flow to ensure that the converter does not become overloaded. In the case that the converter does become overloaded, the operator must reduce the rate of flow for safety reasons.
After the transfer of material is complete, the converter must be operated at a consistent temperature to prevent thermal fluctuations. Generally, the temperature should remain between 1660 and 1730°C. During operation, the operator must increase or decrease the natural gas and other fuel sources as needed.
After the desired steel temperature is achieved, the operator can shut down the converter and its associated systems. The operator must then perform a thorough post-operation inspection of the unit, paying attention to the piping, nozzle, and combustion chamber cover specifically.
Once the post-operation inspection is complete, the operator is then required to clean and maintain the converter appropriately. This includes removing any carbon deposits, replacing parts that have become worn or damaged, and performing general upkeep.
The procedure for converter operation as outlined here is designed to ensure the safe and efficient operation of converters. Following this procedure helps ensure that the unit is operated according to the manufacturer’s guidelines and that the operator is using the proper safety protocols. If this procedure is followed correctly, the company and its operators can be assured that the converter will be operated safely and effectively.
