Description

В насто щее врем  формы точного лить  (елки) перед заливкой к них металла нагревают до 850-950° и прокаливают на поддонах в камерных и толкательных печах. К недостаткам этих печей следует отнести отсутствие у них охладительных камер, частые разрушени  форм, необходимость применени  -ручного труда и малую производительность.At present, precision casting molds (Christmas trees) are heated to 850–950 ° before metal is poured to them and calcined on pallets in chamber and pusher furnaces. The disadvantages of these furnaces should be attributed to their lack of cooling chambers, frequent destruction of forms, the need for manual labor and low productivity.

Конструкци  описываемой печи имеет камеру дл  охлаждени  форм, а дл  их транспортировки - подподовый вертикально замкнутый конвейер, изготовленный из обычной углеродистой стали, с закрепленными на нем кронштейнами дл  елок точного лить . Эти конструктивные особенности выгодно отличают новую печь тем, что она  вл етс  более производительной, к.п.д. ее более высок, а на изготовление конвейера не затрачиваютс  дорогосто щие жароупорные стали.The design of the furnace described here has a chamber for cooling the forms, and for their transportation, a sub-floor, vertically closed conveyor made of ordinary carbon steel with brackets for precision casting trees fixed on it. These design features distinguish the new furnace in that it is more productive, efficiency. it is higher, and expensive heat-resistant steels are not expended on the manufacture of the conveyor.

Печь состоит из сварного каркаса, обшитого металлическим листом и футерованного огнеупорным и термоизол ционным кирпичом. Дл  движени  замкнутого конвейера в поду печи имеютс  щели. Цепь конвейера изготовлена из углеродистой стали. К пластинам цепи креп тс  кронштейны, на штыри которых устанавливают формы точного лить . Ввиду малых тепловых нагрузок, испытываемых кронштейнами, они изготовлены из безникелевой жароупорной стали марки Х-28.The furnace consists of a welded frame lined with a metal sheet and lined with refractory and insulated bricks. There are slots in the hearth of the furnace to move the closed conveyor. The conveyor chain is made of carbon steel. Brackets are attached to the chain plates, on the pins of which the molds are set to be precisely cast. Due to the low thermal loads experienced by the brackets, they are made of X-28 non-nickel heat-resistant steel.

Дл  сжигани  природного газа печь оборудована четырнадцатью инжекционными горелками. Газ сгорает в тоннел х, направленных к своду рабочего пространства печи во избежание пережога форм. Охладительна  камера располагаетс  у выходной части печи и представл ет собой металлический кожух, через .который при помощи вентил тора просасываетс  воздух из цеха.The furnace is equipped with fourteen injection burners for burning natural gas. Gas is burned in tunnels that are directed to the roof of the furnace's working space in order to avoid over-burning the forms. The cooling chamber is located at the outlet of the furnace and is a metal casing through which the air from the workshop is sucked through with a fan.

№ 132655- 2 Предмет изобретени No. 132655- 2 Subject of the invention

Проходна  конвейерна  газова  печь с охладительной камерой дл  прокалки и охлаждени  форм точного лить , отличающа с  тем, что с целью экономии жаропрочной стали, увеличени  к.п.д. печи, применен подподовый вертикально замкнутый конвейер, изготовленный из обыкновенной углеродистой стали, к которому закреплены кронштейны дл  установки и транспортировки елок форм точного лить .A continuous gas conveyor furnace with a cooling chamber for calcining and cooling precision casting molds, wherein in order to save heat-resistant steel, an increase in efficiency furnace, applied under-floor vertically closed conveyor, made of ordinary carbon steel, to which brackets are fixed for installation and transportation of Christmas trees of exact casting forms.
