This practice establishes the controls required for hot rolling mill solution heat treatment of the 6xxx series aluminum alloy plate in Table 1 when ASTM material specifications allow use of this process instead of furnace solution heat treatment. For the alloys listed in Table 1, this practice is an alternate process to solution heat treatment in a furnace, such as specified in Practice ...
The reheat furnace control system must adjust to the temperature, mass and distribution of the incoming steel. Overheating the steel wastes energy, limits the rolling speed, and adversely affects the properties of the steel. Underheating the steel also affects steel properties and risks damage to the rolls.
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.
Oct 24, 2019· 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 presence of hot metal and accurately time the roll stand operation. Pyrometers can be used to measure the roll temperature as water cools the roll during the quenching process.
A Review On: Efficient Energy Optimization In Reheating Furnaces 19 product, yield, energy consumption, pollution and the economics of the product. In modern walking beam reheating furnaces, semifinished products such as slabs/blooms/billets are uniformly heated to a desired temperature and have minimized skid marks. The
The forging furnace is used for preheating billets and ingots to attain a ''forge'' temperature. The furnace temperature is maintained at around 1200 to 1250 oC. Forging furnaces use an open fireplace system and most of the heat is transmitted by radiation. The typical load is 5 to 6 ton ... Rerolling mill furnace a) Batch type
NonContact Temperature Sensors for Improved Process Monitoring and Greater Efficiency: LumaSense offers a broad selection of solutions for metal processing. MIKRON thermal imagers and IMPAC pyrometers are used throughout the steel manufacturing process, where accurate temperature monitoring is required for improved control.
Hot Rolling Mills In metalworking, rolling is a metal forming process in which metal stock is preheated up to 1300°C (2400°F) and passed through rollers to reduce thickness. Hot rolling processes include preheating furnaces, scale breakers, slab scale, rough stand, finishing stand and cooling lines.
Fully featured, highperformance SPOT pyrometer is available in the range of operating wavelengths for fixed spot noncontact infrared temperature measurements.
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.

Jun 01, 2017· The reheating furnace heats the charged steel material to the rolling temperature for its hot rolling in the rolling mill. Rolling temperature is that temperature which makes the steel charge suitable for the plastic deformation in the rolling process. For this, the steel is to have temperatures where its microstructure is in the austenitic range.

Measuring temperatures on metal with infrared technology by Optris. In the production as well as in the processing of metal, the monitoring of the temperature with noncontact sensors does not only help in the surveillance and optimization of the procedure, at temperatures of up to 3,000 °C (5,432 °F), it also improves workplace security.. Continous temperature monitoring is a key factor in ...
This typical practice for billet measurement is too late for feedback control and too early for billet confirmation. Moreover, the point of measurement coincides with the period at which the billet surface temperature is least uniform and most variable. Best Practices. Billet Heating: Measure the billet while it is still inside the furnace. For ...
Hot rolling mill. In hot rolling mills, long products ( wire rod, pipes, bars, rails, beams) or wide flat products ( sheets, strip) are fabricated by rolling. A hot rolling mill consists of a reheating furnace, a descaling unit, a roller conveyor, a hot mill stand and a cooling bed.
