Description
Обычно примен емые способы тепловой сушки литейных форм основаны на обогреве впутренпей поверхпостп формы гор чими газами з сушилах или же поверхпостпой подсушкой переносными печами на месте изготовлени форм. При этом необходимо значительное врем дл сушки крупных литейных форм или неизбежен перегрев поверхностных слоев.Commonly used heat-drying methods for casting molds are based on heating the molds with suction gases using dry gases or drying them with portable ovens at the place of production of the molds. At the same time, considerable time is required for drying large casting molds or inevitable overheating of the surface layers.
Описываемый способ не имеет этих недостатков, так как в толще формовочной смеси вдоль стенок формы помешкают трубы, подключенные к источнику гор чего газа, который производит сушку формы. Такой способ сокраш;ает процесс сушки и обеспечивает сушку по всей то,тше формы.The described method does not have these disadvantages, since the pipes connected to the source of hot gas, which produces drying of the form, are hardened along the walls of the mold. This method shortens the drying process and provides drying throughout the whole, lower form.
На чертеже показана форма в разрезе. Вдоль стенок формы внутри кессона / прокладываютс трубы 2 с отверсти ми 3 на стороне, обращенной к отливке. После изготовлени литейной формы трубы оказываютс в толще формовочной смеси. Концы труб с одной стороны заглушены, а с другой - соедин ютс с общим коллектором, через который в трубы подаютс гор чие газы. Выход из труб через отверсти , газы проход т через толщу формовочной смеси. В процессе сущки полость формы может быть открыта или перекрыта плитой 4.The drawing shows a sectional shape. Pipes 2 are laid along the walls of the mold inside the caisson / 2 with holes 3 on the side facing the casting. Once the casting mold is made, the pipes are in the thickness of the molding sand. The ends of the pipes are plugged on one side, and on the other side they are connected to a common collector through which hot gases are fed into the pipes. The exit of the pipes through the holes, the gases pass through the thickness of the molding sand. In the process of the substance, the cavity of the form can be opened or blocked by the plate 4.
В св зи с тем, что сушка осуществл етс иепосредственпо продувкой газов через толщу формы, диффузионные процессы перемещени влаги замен ютс непосредственным испарением ее при соприкосисвеиии с гор чими газами и механическим выносом образующегос пара из толщи формы этими газами. Поэтому период процесса сушки сокращаетс .Due to the fact that the drying is carried out and the gases are blown through the thickness of the mold, the diffusion processes of moisture transfer are replaced by direct evaporation when in contact with hot gases and the mechanical removal of the resulting vapor from the thickness of the shape of these gases. Therefore, the drying process period is shortened.
Предмет и з о б р е т е н м Subject and title
Способ сушки литейных форм продувкой гор чими газами, отличающийс тем, что, с целью продувки всей толщи формы, в формовочной смеси вдоль стенок формы помещают трубы с отверсти ми, подключенные к источнику гор чего газа.A method of drying casting molds by blowing with hot gases, characterized in that, in order to blow out the entire thickness of the mold, pipes with holes connected to the source of hot gas are placed in the molding mixture along the walls of the mold.
