Description
- . Посредством предлагаемого способа имеетс в виду избежать при нагреве.пе-, ред закалкой в сол ной ванне обезугле--: роживающего. действи ванны.-. By means of the proposed method, it is intended to avoid during heating. Dehydration, hardening in a salt bath, a disintegrated--: giving birth. bath action.
На чертеже фиг. 1 изображает в продольном разрезе приспособление, по сн ющее прймейение предлагаемЬго способа и фиг. 2-то же, другойвариант. ;,/ In FIG. 1 shows, in longitudinal section, a device that explains the note of the proposed method and FIG. 2 is the same, another option. ;, /
На дно сол ной ванны А (фиг. 1) опускают крэд-лую плоскую коробку, в. которую газ подают по трубке 5 от централь-, ной станции. Эта коробка состойт из.; круглого металлического диска 1 с бортом 2. Борт 2 имеет внутреннюю варезку , в которую ввинчивают д,иск 3 со множеством отверстий 4 Газ, пройд по трубке. 5, вступает в узкое пространство между дисками 1 и 3 и, пробива сь через мелкие отверсти 4, поднимаетс вверх через расплавленную соль. По выходе из ванны, газ удал етс через выт жку. Беспрерывно идущие через ванну струйки газа будут нейтрализовать обезуглероживающее действие сол ной ванны. Дл предохранени заливани отверстий 4 при опускании приспособлени в ванну, сверх диска 3 вставл ют крышку 6 с ручкой 7,имеющей кольцо 8. После опускани приспособлени и пуска газа эту крышку отвертывают, и действие газа происходит вышеуказанным пор дком.At the bottom of the salt bath A (Fig. 1), the cradle flat box is lowered, c. which gas is fed through pipe 5 from the central station. This box is made of; round metal disc 1 with side 2. Board 2 has internal cutting, into which g is screwed, suit 3 with a plurality of holes 4 Gas, passed through the tube. 5, enters the narrow space between the disks 1 and 3 and, breaking through the small holes 4, rises up through the molten salt. Upon leaving the bath, the gas is removed through a hood. Trickles of gas continuously flowing through the bath will neutralize the decarburizing effect of the salt bath. To prevent the holes 4 from being poured in when the device is lowered into the bath, a cover 6 with a handle 7 having a ring 8 is inserted over the disk 3. After the device is lowered and the gas is started, this cover is unscrewed and the gas is applied in the above order.
. В-Случае отсутстви газовой установки на месте потреблени , в кладку Л, р дом с ванной 5 (фиг. 2), устанавливают баллон-1 который наливают нефть или масло 2.На фланец баллона 1 накладывают прокладку 3 и крышку 4, закрепл ем мую болта ми 5. В крышку 4 впаивают тр|убку 6 Когда нефть нагреетс отход щим газом, она начнет выдел ть углеводороды . Эти газы по трубке б поступают в вышеописанное приспособление и действуют , как указано выше.. In the case of the absence of a gas installation at the place of consumption, the cylinder 1, next to the bathroom 5 (Fig. 2), is fitted with a cylinder-1 which is poured with oil or oil 2. A gasket 3 and a lid 4 are placed on the flange of the cylinder 1 and fixed with bolts 5. In the lid 4, the tr | batch 6 is soldered. When the oil is heated by the flue gas, it will start to release hydrocarbons. These gases through pipe b enter the above-described fixture and act as above.
Давление газа в баллоне 1 измер ет манометром 7, а излишний газ выпускаетс через, предохранитель 8.The gas pressure in the cylinder 1 is measured with a manometer 7, and the excess gas is discharged through the fuse 8.
