Description
Центробежна отливка напорных чугунных труб получила широкое применение, так как этот способ дает наибольшую производительность и в то же врем повышает качество труб.Centrifugal casting of cast iron pressure pipes is widely used, since this method gives the highest productivity and at the same time improves the quality of pipes.
Однако при центробежной отливке в металлические формы фановых труб последние приобретают значительную хрупкость вследствие отбела их наружной поверхности. Хрупкость можно уменьшить отжигом труб, но тогда значительно повысилась бы их стоимость. Этим объ сн етс , почему центробежна отливка в металлические формы фановых и других тонкостенных труб не получила распространени .However, when centrifugal casting into metal molds of the funic pipes, the latter acquire considerable fragility due to the chill of their outer surface. The brittleness can be reduced by annealing the pipes, but then their cost would increase significantly. This explains why centrifugal casting into metal molds of fan pipes and other thin-walled pipes did not become widespread.
Предлагаемый способ отливки фановых и других тонкостенных труб из чугуна состоит в том, что в чугун до заливки в форму центробен ной машины присаживают инокул ры (ферросилиций, ферротитан, графит, силикокальций и др.) н термит, с целью повысить жидкотекучесть металла .The proposed method for casting fan-shaped and other thin-walled pipes from cast iron consists in that inoculums (ferrosilicon, ferrotitanium, graphite, silicocalcium, etc.) are placed on the thermite before casting into the form of a centrifugal machine in order to increase the fluidity of the metal.
Дл такой отливки пригоден чугун любого состава, примен емый дл производства фановых и тонкостенных труб или любого машинного лить .For this casting, cast iron of any composition suitable for the production of funeral and thin-walled pipes or any machine casting is suitable.
Вследствие -высокой жидкотекучести получаемого чугуна и значительного интервала его затвердевани отливку тонкостенных труб обычных стандартных размеров можно производить с одного конца формы при отсутствии поступательного движени желоба или формы. Благодар этому отливка может производитьс на машинах простой конструкции .Due to the high fluidity of the resulting iron and a considerable interval of its solidification, the casting of thin-walled pipes of usual standard sizes can be made from one end of the form in the absence of the translational movement of the chute or form. Due to this, the casting can be carried out on machines of simple construction.
Предмет изобретени Subject invention
Центробежный способ отливки в металлические формы фановых н других тонкостенных труб, отличающийс тем, что в чугун перед его заливкой в форму присаживают инокул ры и термит, с целью повышени жидкотекучести металла.A centrifugal method of casting metal thinner-walled pipes and other thin-walled pipes, characterized in that inoculums and thermite are placed in the cast iron before it is poured into the mold, in order to increase the fluidity of the metal.
