Centrifuge for casting steel tube by heated mould method

Abstract

The invention relates to a pipe casting centrifuge machine by a thermodyn process, which comprises an equivalently casting device, a centrifugal host, a pushing pipe device, a pipe supporting device and a pipe connecting device. The frame of the equivalently casting device is fixed with a ladle fixing frame and a pouring ladle with a long pouring channel, and the ladle fixing frame is fixed with a same-speed board; the support wheel groups of centrifugal host are driven by a motor and support pipe die; the supporting frame of the pushing pipe device fixes a pushing rod through a guide rail, and the pushing rod is driven by a motor through pin teeth transmission for the pipe rough breaking away from the pipe die and cleaning inner wall of the pipe die and coating the inner wall of the pipe die; the pipe supporting device ensures the separation of the steel pipe from the pipe die; the pipe connecting device is used for connecting the pipe rough separated from the pipe pushing device. The pipe casting centrifuge machine of the invention can obtain the hollow steel pipe with good structure, precise size and high output rate of material and realizes whole machine automatic production.

Description

technical field [0001] The invention relates to a centrifuge for hot mold casting steel pipes. Background technique [0002] Due to the complex manufacturing process of large-diameter thick-walled seamless steel pipes and the high technical content of the required equipment, currently only Wuhan heavy-duty casting and forging plants in China adopt the punching-drawing process for production. The process route is: ingot heating-vertical piercing- Secondary heating - multi-ring die drawing - heat treatment - internal and external machining - finishing. The equipment is complicated, and the finished product can only be obtained through a large amount of cutting, the material utilization rate is low, and the energy consumption is relatively high. There is no relevant report on casting large-diameter steel billet centrifuges in China. In some foundries, centrifugal casting steel billets are also used to produce reduced magnesium tanks. However, due to low output and simple centr...

The equipment is complicated, and the finished product needs to be cut through a large amount, the material utilization rate is low, and the energy consumption is high

Casting large-diameter steel billet centrifuges have not been reported in China. In some foundries, centrifugal casting steel billets are also used to produce reduced magnesium tanks. However, due to low output and simple equipment for centrifuges, manual operations are often used, and the quality cannot be guaranteed.
