run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...

Bolandparchen metamorphic complex located in the NW Zanjan city and is at the border of Central Iran and Sanandaj-Sirjan Zones. The study area contains different schists, impure marble and metsandstone that intruded by granitic bodies in the central and northern parts. Central part of Bolandparchen complex cut by NW to SE fault. Petrographic study, whole rock analysis, microprobe analyses and B...

Mollataleb area is located in the north of Aligudarz city, in the Sanandaj-Sirjan metamorphic zone. The regional metamorphic rocks with Upper Triassic-Jurassic age and various granitoid units are the most important geological event that occurred in the area. The development of granitoid masses in Aligudarz area aged Middle Jurassic that intruded into schists. Microprobe analyses of tourmalines ...

The study area is a part of Sanandaj- Sirjan Zone that is located in the northeastern of the dimension stone of Jan mine in north of Doroud city on Lorestan Province. It is mainly composed of deformed metamorphic rocks including deformed marbles associated with mylonitic gneiss- granite and amphibolite. The main texture of the marbles is lepidogranoblastic and their mineralogical composition ar...

East Salmas gneisses are located in the northernmost parts of the Sanandaj-Sirjan zone and are seen in banded and deformed with the 6 different groups of lithological diversity. Their protolith is of paragneiss type with arkosic sedimentary rock type.Texturally, they are immature. Based on this study, chemical maturation trend of protolith of the present investigated gneisses are in the arid to...

Malmir area is located in the east of Doroud city, in the Sanandaj-Sirjan metamorphic zone. The earliest deposits contain a relatively uniform sequence of slates and phyllites with silisic veins and veinlet. Various granitoid units, with Middle Jurassic age, are the most important geological event that occurred in the area. Microprobe analyses of tourmalines in pegmatites and and quartz-tourmal...

The study area is located in northern part of metamorphic belt of Sanandaj-Sirjan in east of Hamedan Batolith. This area is mainly composed of regional metamorphic rocks, such as staurolith, andalusite, silimanite and garnet bearing mica schists and slates, with nearly NW-SE trend. The age of these rocks (tectonites) are Pre-jurassic and have experienced two stages of deformation during du...

The Azad pumped storage power plant including the pumping and transformer cavern and surge tanks has been located in the Sanandaj-Sirjan formation with the alternation of slate and phyllite and meta sandstone.Due to the sensitivity and special use of these spaces, stability analysis and ensuring the safety of carven is very important.Nowadays, using the surface storage tanks is very costly; The...
