TMT Quenching System. The TMT i. e Thermo metallurgical treatment to the bar is imparted by treating the hot bar by water. In the rolling mill, the billets / ingots are heated in the reheating furnace and rolled through different rolls, progressively reducing the section. The bar releasing from the final stand is subjected to water treatment.

For roll cooling applications of hot steel pure water is normally used as a coolant. The water is usually re-circulated in the plant and should have a sufficient filtration grade in order to prevent clogging of the nozzles. The maximum particle size shouldnot exceed 1/3 of the smallest nozzle internal passage.

An operation in which steel is heated above a critical point or recrystallization temperature for a period of time and then slowly cooled to a cooling rate less than that in still air is called annealing. After the steel is austenitized and rapidly cooled at a rate greater than the critical cooling rate, the supercooled austenite can be transformed into martensite. This operation is called ...

Quenching From the finished mill stand, the hot rolled bar enters into the 'Thermex System' and is quickly cooled by a water spray system. As the TMT re-bar is quickly cooled, its surface hardens to a depth optimized for each section, creating a martensitic rim and the core remains hot and austenitic.

High-pressure piping will be made of pipe steel, in order to connect pipe flow to the valves for descaling and complete with heavy-duty PP clamps, fittings, hoses, etc. Descaling speed on the liner = 1.5–4 m/sec. Water descaling unit operates according to the required rolling speed/ mill capacity. MODEL 2.

However, in hot-rolling mills, water used for descaling and cooling steel (process water) and water used for cooling rolls and bearings (cooling water) were reported together. Inasmuch as the steel indus­ try generally considers all water used in rolling mills as cooling water, it is reported as such in this report.

Cooling after hot rolling should be as fast as possible without any delays between exiting the rolling mill and the start of quenching. 2. The hot rolling parameters should be adjusted to ensure that the rolling finish temperature is either below 250°C or above 400°C. 3. The period between water quenching and artificial aging should be as ...

A hot-rolling and QST process was conducted at a rolling workshop of Steel mill in Incheon, South Korea. The operation consisted of 11-pass reversing rolling and direct water spray quenching. Key control factors in beam manufacturing were …

Open recirculating systems include: the dust removal system used for coke quenching; this system is equipped with rectangular scraped settling tanks. The overflow from these tanks is partially recycled. We should also note the following: 50% of water is evaporated during the quenching process; salinity restrictions for the feed water limiting ...
