Stainless Steel Rolling Mill For High Precision Cold Rolled Round Stainless Pipes
I. Features of stainless steel pipes and application
Stainless steel pipes have good corrosion resistance, heat resistance, and mechanical properties, and have good hot workability such as stamping and bending, without heat treatment hardening. It is widely used in tableware, cabinets, boilers, auto parts, medical appliances, building materials, food, chemical and other industries. High precision is often produced on cold rolling mill.
II. What is cold rolling mill?
Cold pilger mills use a special cold forming process which is both cost-efficient and indispensable for many applications. It is used to improve roundness, stress homogeneity, and surface roughness of the tubes. The tolerance of finished tubes is about ±0.05mm.
III. Working principle of steel rolling mill
Cold rolling mill uses ring die to roll seamless steel tube in cold state. The belt wheel is driven by main motor via small belt pulley. One hand, the power changes rotary motion of crank connecting device into straight reciprocating motion of main frame; the other hand, the photoelectric disc sends signal to feeding & rotation box to realize feeding and rotation motion.
The roller of this machine is ring die type, which not only has compact structure, but also adapts to long working stroke. The tapered hole of roller keeps the same with taper of mandrel. When the main frame go ahead, the shaped hole is turning from large to small and the mother tube is rolled continuously. When the main frame goes back, the shaped hole is turning from small to large, the mother tube is rolled and finishing. During process of one stroke, the mother tube is feed for a fixed distance and rotated for a fixed angle. This kind of stroke is continuous and reciprocating, it is the process of rolling.
