Monitoring also ensures temperature uniformity and consistent product quality, reducing wastage. Controlling the reheat furnace is key to reducing the costs of fuel and time needed for this stage. It also offers the final opportunity of checking the steel temperature before it enters the rolling mill.
Mar 08, 2018· Single-point radiation thermometers, also referred to as infrared pyrometers, have been widely used in steel hot-rolling mills for more than 60 years. They offer many advantages compared to contact sensors such as thermocouples. Single-point radiation thermometers are installed at a distance, and they view the infrared radiation that is emitted by the target object.
ASTM-B947 Standard Practice for Hot Rolling Mill . ASTM-B947 Standard Practice for Hot Rolling Mill Solution Heat Treatment for Aluminum Alloy Plate The accuracy of temperature measuring system(s) shall be tested under operating conditions at least once during each week that the facility is used.
Blast Furnace Temperature measurement and control is essential for ... Infrared sensors measure strip and sheet temperature so that rolling mill stands can be efficiently set to match the steel's temperature. Sensors can be used to detect the ... responses to accurately measure system temperature.
Contact-free measurement of the temperature in steel and rolling mills and in metal working. The monitoring of temperature with contact-free yet precise measurement of the object is gaining tremendous importance in the steel and iron industry.
This mill process involves rolling and reducing steel at a high temperature to achieve the required thickness. Our product range provides essential temperature measurements at key process points, in hostile conditions.
Walking beam furnaces are used for heating slabs, billets, or rods prior to the rolling process. The goods which are to be heated are moved inside a walking beam furnace. The temperature in a walking beam furnace can normally reach up to 1,200°C.
Hot Rolling Mill Steel Ametek Land. Hot rolling mill sophisticated and rugged understrip pyrometers provide high quality temperature measurements when the top side of the strip may be obscured by black water ametek land manufactures and supplies a complete range of noncontact temperature measuring systems designed specifically for hot metal rolling applications all over the world
The reheat furnace control system must adjust to the temperature, mass and distribution of the incoming steel. Over-heating the steel wastes energy, limits the rolling speed, and adversely affects the properties of the steel. Under-heating the steel also affects steel properties and risks damage to the rolls.
rollable temperature in a reheating furnace. This is the starting point of the hot rolling mill practice. Reheating Furnace x Cold stocks are heated to make them soft and thus suitable for rolling. x Furnace has three parts: walls, roof and hearth. Furnace is lined with several layers of refractory bricks. It is insulated by glass wool.
Landscan infrared linescanners, Furnace Thermometers System (FTS) and Understrip Temperature Measurement System are aimed specifically at hot rolling mill applications. • Radiation thermometers need no contact with the measured object, which means no contamination, interference or damage caused to the products or the equipment.
HOT ROLLING MILLS. In a hot rolling mill process, the steel gets heated at extremely high temperature, which is generally above 1100°C. BLH Nobel can provide sensors and complete measurement systems that are highly durable and withstand the extremely harsh environment in the steel industry production sites.
For Continuous Reheating Furnace and Walking Beam Reheating furnaces, the temperature changes along the length of the furnace. Because of the difference of steel grade, section size, charging temperature and rolling process, the temperature system adopted is also different. There are one-stage, two-stage, three-stage and multi-stage temperature ...
Sensor systems for process optimisation in rolling mills and strip finishing lines References (extract) For more than 40 years, Micro-Epsilon has been a reliable industrial part-ner in precision measurement technology for inspection, monitoring and automation. Systems and …
Santanu Chakraborty, in Treatise on Process Metallurgy: Industrial Processes, 2014. 6.5 Rolling Mills. The rolling mill facilities were designed to meet the production requirement of Table 1.The rolling mills complex was proposed to include a light and medium merchant mill with breakdown group of stands for rolling blooms into billets and an intermediate in-line heat compensating furnace; a ...
We have rolling mill furnace temprature measuring system,Temperature control is critical throughout the Hot Rolling Mill to yield the desired product properties ensure quality product and improve line speed 1 Reheat Furnace Entry Exit The reheat furnace control system must adjust to the temperature mass and distribution of the incoming steel
Mar 12, 2020· The reheat furnace brings the cold steel to the correct temperature for rolling. Temperature measurements here allow for optimised heating trajectories, providing considerable energy savings.
Rolling Mill Furnace This is the heart of any hot rolling mill where in the charge is heated to rolling temperature. The charge could be in the form of billets, blooms, slabs or ingots.The type of furnace could be pusher, walking hearth or walking beam – either top fired or top and bottom fired.
