Abstract
Изобретение относитс к черной металлургии, а также промышленности строительных материалов и может быть использовано дл переработки металлургических шлаков. С целью повышени производительности подают струю расплава шлака в зазор между барабанами, вращающимис в противоположном направлении, и одновременно с двух сторон в зазор между струей расплава и поверхност ми валков подают охлажденный до твердого состо ни шлак в количестве 20-25% от общей подачи. Производительность уве- личиваетс в 1,5-2 раза. 1 ил.The invention relates to ferrous metallurgy as well as the building materials industry and can be used for the processing of metallurgical slags. In order to increase productivity, a stream of molten slag is fed into the gap between the drums rotating in the opposite direction, and simultaneously from two sides, slag cooled to solid state is fed into the gap between the melt stream and the roll surfaces in the amount of 20-25% of the total feed. Productivity increases 1.5-2 times. 1 il.

Изобретение относитс к черной металлургии, а также промышленности строительных материалов и может быть использовано дл переработки предпочтительно металлургических шлаков.The invention relates to ferrous metallurgy as well as the building materials industry and can be used to process preferably metallurgical slags.
Цель изобретени - повышение производительности .The purpose of the invention is to increase productivity.
На чертеже показана установка дл осуществлени способа.The drawing shows an installation for carrying out the method.
Расплав шлака из емкости 1 подают на барабаны 2. Часть расплава шлака в количестве 50-80% от общего расхода шлака, подаваемого в зону междуThe slag melt from the tank 1 is fed to the drums 2. A portion of the slag melt in the amount of 50-80% of the total consumption of slag supplied to the zone between
Пример. Жидким шлаком заполн ют 10-тонный емкость-копильник на 1/3 его объема. Example. Liquid slag is filled with a 10-ton storage container for 1/3 of its volume.
В процессе заполнени копильника барабаны 2 вращаютс в противоположные стороны (двигатель Д31, 8 кВт, диаметр барабанов 1400 мм). Расплав шлака через сливную щель длиной 800 мм и шириной 30 мм сливаетс в зев между барабаном 2. Часть расплава - 60 от общего расхода - проходит через зазор между барабанами (ширина зазора составл ет 20 мм), аIn the process of filling the storage chamber, the drums 2 rotate in opposite directions (D31 engine, 8 kW, 1400 mm diameter drums). Slag melt through a drain slot 800 mm long and 30 mm wide merges into the shed between the drum 2. A part of the melt — 60 of the total flow — passes through the gap between the drums (the width of the gap is 20 mm), and

Величина толщины сло пшака на барабанах регулируетс отсе кател ми 3 и может сост.авл ть 7-15 мм Охлажденный до твердого состо ни шлак 4 через направл ющие лотки 5, установленные под углом естественного откоса, подают на охлаждающие (формующие) валки 6 и на струю расплава шлака 7 дл образовани вокруг струи постели из твердого шлака. drums, passes through the inter-15 gap, the rest goes through the drums, and the rest (20-50%) at the expense of which, opposite to each other, cools down on the surfaces of the drums to a temperature of 300-350 ° C below the melt temperature - laziness of slag. The thickness of the pshak layer on the drums is controlled by the compartments 3 and can be 7-15 mm. The slag 4, cooled to a solid state, is guided through guide trays 5 installed at an angle of repose, to the cooling rolls 6 and molten slag jet 7 to form a solid slag bed around the jet.
Лотки 5 установлены на шарнирах 8 и имеют окна с крьш1ками 9 дл i сброса избытка шлака в бункера 10.The trays 5 are mounted on the hinges 8 and have windows with holes 9 for i dumping excess slag into the hoppers 10.
Расплав шлака,проход через зазор между барабанами 2 и формировател ми 11 потока, попадает в зазор между валками 6 и шлаком 4.Slag melt, the passage through the gap between the drums 2 and the flow former 11, falls into the gap between the rolls 6 and slag 4.
За счет отбора тепла из расплава охлажденным шлаком создаютс благопри тные услови дл увеличени зазора между валками 6, т.е. дл увеличени пропускной способности балков 6 увеличение скорости их враще- 5 600°С, а в валках 13 производ т дроб- ни . В валках 6 частично формируетс ление шлака. Производительность при полоса из шлака, KOTOpyjo направл ют в валки 12, где происходит дополниуказанных параметрах 7-12 т/ч.By extracting heat from the melt with cooled slag, favorable conditions are created to increase the gap between the rolls 6, i.e. to increase the throughput of the beams 6, an increase in the speed of their rotation is 5,600 ° C, and fractions are made in the rollers 13. In the rolls 6, slag formation is partially formed. The capacity with a slag strip, KOTOpyjo, is directed to the rolls 12, where the additional parameters of 7-12 t / h occur.
