Description
Известны способы охлаждени водой кристаллизаторов на установках непрерывной разливки металла.Methods are known for cooling water molds in continuous casting plants.
Вод ное охлаждение имеет р д недостатков: большой температурный перепад между разливаемой сталью и холодной водой в образующейс корочке слитка вызывает большие внутренние напр жени , что влечет за собой ухудшение качества слитка; большие скорости воды в каналах кристаллизатора (8-10 м1сек) привод т к большому расходу воды (до 1500 ); прекраш,ение подачи воды в систему хот бы на очень короткое врем влечет за собой прогар медных стенок кристаллизатора , а следовательно, и крупную аварию.Water cooling has a number of drawbacks: a large temperature difference between cast steel and cold water in an ingot crust that forms creates large internal stresses, which leads to a deterioration in the quality of the ingot; large water velocities in the channels of the crystallizer (8-10 m1sec) result in high water consumption (up to 1500); stopping the supply of water to the system at least for a very short time entails a burnout of the copper walls of the mold, and, consequently, a major accident.
Предлагаемый способ испарительного охлаждени кристаллизаторов на установках непрерывной разливки металла вл етс новым.The proposed method of evaporative cooling of crystallizers in continuous metal casting plants is new.
Применение испарительного охлаждени кристаллизаторов устран ет недостатки вод ного охлаждени .The use of evaporative cooling of the molds eliminates the disadvantages of water cooling.
При этом, химически чистую воду из бака-сепаратора подают в кристаллизатор, из которого она, нагревшись до состо ни паровод ной смеси, поступает оп ть в бак-сепаратор, откуда пар отводитс потребител м .At the same time, chemically pure water from the separator tank is fed to the crystallizer, from which it, being heated to the state of steam-water mixture, enters again into the separator tank, from where the steam is removed by the consumer.
На чертеже показана принципиальна схема осушествлени предлагаемого способа.The drawing shows a schematic diagram of the implementation of the proposed method.
В кристаллизатор / подают химически чистую воду из бака-сепаратора 2 насосом 3. Кристаллизатор и бак-сепаратор соединены трубами 4 и 5. Труба 6 служит дл наполнени системы очищенной водой. Пар к потребител м отвод т по трубе 7. Предусмотрен обвод 8 дл работы системы на естественной циркул ции, включаемый с помошью задвижек 9.В заключении Центрального научно-исследовательского института черной металлургии им. И. П. Бардина указано, что применение испарительного охлаждени позволит резко сократить мош,ность и объем цикла оборотной воды. Институт рекомендует предложение к проверке в промышленных УСЛОВИЯХ.

The crystallizer and the separator tank are connected by pipes 4 and 5. Pipe 6 is used to fill the system with purified water. Steam to consumers is diverted through pipe 7. A bypass 8 is provided for operation of the system on natural circulation, which is switched on by means of gate valves 9. At the conclusion of the Central Research Institute for Ferrous Metallurgy named after IP Bardin indicated that the use of evaporative cooling will drastically reduce the mosh, the consistency and volume of the circulating water cycle. The Institute recommends a proposal for verification in industrial conditions.
