Изобретение относитс  к литейному производству , а именно К непрерывному горизонтальному литью чугуиа и предназначено дл  распылени  воды при вторичном охлаждении заготовок.The invention relates to foundry, namely, to continuous horizontal casting of iron and is intended for spraying water during the secondary cooling of billets.

Известны водо-воздушные форсунки, примен емые при непрерывном вертикальйбм литье стали и расчитанные на посто нное давление сжатого воздуха, подаваемого из цеховой магистральной сети и посто нный расход воды 1.Water-air nozzles are known that are used in the continuous vertical casting of steel and designed for a constant pressure of compressed air supplied from the shop main network and a constant water flow 1.

Однако изменение давлени  воздуха или расхода воды в форсунках приводит к ухудшению их работы. Так например, водо-воздушна  форсунка состоит из двух трубок, по одной из них полаетс  сжаты воздух, а по другой, расположенной тангенциально по отношению к первой, вод.а. Така  форсунка работает только при определенном посто нном расходе воды и сжатого воздуха. При уменьшении давлени  воздуха или увеличении количества воды резко падает качество расйыла,. а при уменьшении д,аШёни  воды воздушна  стру  «запирает вод ную трубку и полача воды прекращает ; В результате вод.о-воздушна  форсунка неHowever, a change in air pressure or water flow in the nozzles leads to a deterioration in their performance. So, for example, the air-water nozzle consists of two tubes, one of them has compressed air, and the other, which is tangential to the first, water. This nozzle works only with a certain constant flow of water and compressed air. When the air pressure decreases or the amount of water increases, the quality of the spray drops sharply. and when d decreases, the airflow “closes the water pipe and stops the water; As a result, the water nozzle is not

пригодна дл  непрерывного горизонтального лить  чугуна.suitable for continuous horizontal casting of cast iron.

Известны вод ные форсунки дл т вторичного охлаждени  стальных слитков при вертикальном непрерывном литье. Основное назначение их - это интенсивное охлаждение слитков с целью уменьшени  длины жидкой лунки и предотвращени  прорыва жидкого металла.Water nozzles are known for the secondary cooling of steel ingots in vertical continuous casting. Their main purpose is the intensive cooling of ingots in order to reduce the length of the liquid well and prevent the breakthrough of the liquid metal.
