- Q: given the buoyant economic growth of india, what you guys think about steel industry? what can be the major issues in this industry in the coming days
- Since2003, India has been the largest sponge iron producer in the world. In 2005, out of total global production of 56.05 mt of sponge iron, India produced around 11.1 mt (19.8%). In line with production target of 110 mt of steel (National Steel Policy) by FY20, many steel producers have announced their capacity expansion plans by signing MOUs with various state governments like Chattisgarh, Orissa and Jharkhand. The steel producers are expected to add around 8 mt of capacity by FY 08. CARE estimates that during 2006-09, demand for steel in the domestic market would grow at a CAGR of 8.4%. HR steel because of its widespread applicability is expected to grow at a CAGR of 17.5%. During this period, major demand drivers would be Consumer durables, Automobiles and Construction. Domestically, steel prices of flat products follow the international trend. Globally, steel prices are expected to firm up with continued growth in steel consumption. Further, the winds of consolidation have gathered pace with Arcelor-Mittal merger and latest acquisition of Corus by Tata Steel. The Indian steel industry has announced huge capacity expansions. With commissioning of these capacities demand-capacity ratio is expected to decline in FY 09 due to excess capacity. Will this lead to a drop in prices with commissioning of these capacities? With China and India becoming the focus of major global steel companies, will the consolidation of steel industry in these countries continue? For comprehensive analysis and CARE’s future outlook on the sector, please refer to the exhaustive report on the Indian Steel Industry by CARE Research.
- Q: What are the common methods of protecting steel coils from corrosion during storage?
- There are several common methods used to protect steel coils from corrosion during storage. These methods are employed to prevent moisture and other environmental elements from coming into contact with the steel coils, which can lead to corrosion. 1. VCI (Volatile Corrosion Inhibitor) Packaging: VCI packaging is a widely used method for protecting steel coils. VCI materials are incorporated into the packaging, such as plastic bags or films, which release a vapor that forms a protective layer on the surface of the steel coils. This layer prevents moisture and other corrosive agents from reaching the steel, thus inhibiting corrosion. 2. Oil Coating: Another widely used method is to apply a thin layer of oil on the surface of the steel coils. The oil acts as a barrier, preventing moisture and oxygen from coming into contact with the steel. This method is particularly effective for long-term storage or transportation of steel coils. 3. Desiccants: Desiccants, such as silica gel packets, can be placed inside the packaging to absorb any moisture that may be present. By reducing the humidity levels inside the packaging, the risk of corrosion is minimized. This method is often used in conjunction with VCI packaging or oil coating. 4. Proper Ventilation: Adequate ventilation is necessary to prevent the accumulation of moisture around the steel coils during storage. By allowing air to circulate freely, it helps to reduce the humidity levels and prevents the formation of condensation, which can lead to corrosion. 5. Controlled Environment: Storing steel coils in a controlled environment can be an effective way to prevent corrosion. This involves maintaining a constant temperature and humidity level, which are not conducive to corrosion. Temperature and humidity control can be achieved through the use of air conditioning or dehumidification systems. It is important to note that the specific method or combination of methods used to protect steel coils will depend on various factors, such as the duration of storage, the environmental conditions, and the specific requirements of the steel coils. Regular inspections and maintenance are also crucial to ensure the ongoing protection of the steel coils from corrosion.
- Q: What is the purpose of coating steel coils?
- The purpose of coating steel coils is to provide protection against corrosion, enhance durability, and improve the aesthetic appearance of the steel. Coatings create a barrier between the steel surface and the environment, preventing moisture, chemicals, and other corrosive elements from reaching the metal. Additionally, coatings can offer additional benefits such as heat resistance, UV protection, and improved paint adhesion, making the steel coils suitable for a wide range of applications in various industries.
- Q: How are steel coils inspected for straightness using laser alignment?
- Steel coils are inspected for straightness using laser alignment through a precise and automated process. Laser alignment technology offers a non-contact method to measure the straightness of steel coils with high accuracy and efficiency. Firstly, the steel coil is placed on a conveyor system that moves it through the inspection area. As the coil passes through, a laser alignment system is set up to emit a laser beam across the width of the coil. This laser beam acts as a reference line for the straightness measurement. The laser alignment system consists of a laser emitter and a receiver unit. The emitter projects a laser beam that is perfectly straight and parallel to the desired alignment. The receiver unit, placed on the opposite side of the coil, captures the laser beam and analyzes its position. As the coil moves through the inspection area, the receiver unit determines the deviation of the laser beam from the desired straight line. This deviation is calculated by analyzing the position of the laser beam at multiple points along the coil's width. The laser alignment system is connected to a computerized control system that processes the data received from the receiver unit. The control system performs complex calculations to determine the straightness of the coil based on the laser beam's position. Any variations or deviations from the desired straight line are recorded and analyzed by the control system. The inspection data can be presented in real-time, allowing operators to monitor the straightness of the steel coil during the inspection process. Using laser alignment for steel coil inspection offers several advantages. It provides highly accurate measurements, ensuring that even minor deviations from straightness are detected. The non-contact nature of laser alignment eliminates the need for physical contact with the coil, reducing the risk of damage or contamination. Additionally, the automated process saves time and increases efficiency compared to manual inspection methods. Overall, laser alignment technology is a reliable and efficient method for inspecting the straightness of steel coils. It ensures that only coils meeting the required straightness criteria are passed, contributing to the quality control of steel manufacturing processes.
