Hot Rolling Mill Seamless Steel Pipe Mill
Everyone is used to naming hot-rolled seamless pipe mills with mandrels for the wall forming process, such as MPM mills and Assel mills. There are two main types of pipe rolling mills, one is a continuous rolling mill, and the other is a cross rolling mill. According to the mandrel operation mode, the continuous rolling mill can be divided into three types: floating mandrel, limited mandrel and semi-floating mandrel. The limited mandrel mill can be divided into two-roll type (MPM) and three-roll type (PQF). The skew rolling mill is divided into three-high rolling mill (Assel) and two-high rolling mill (Accu Roll).
The continuous pipe rolling mill is suitable for the production of large quantities of steel pipes, with high output, long rolled steel pipes (the length of the waste pipe can exceed 30m), the quality of the inner and outer surfaces of the product is good, the specification range is wide, and the D/S is large (over 42). However, its investment is large, there are many spare parts for tools, and it takes a long time to change specifications.
The skew rolling mill is suitable for the production of small batches and multiple varieties of steel pipes. It has low investment, fewer tools and spare parts, low tool consumption, and flexible production. However, the output is low and the rolled steel pipes are shorter (the length of the waste pipe is generally not more than 15m). For thin-walled tubes, the surface quality is unstable, the specification range is narrow, and the D/S is small (generally less than 40).
