Process Classification Of Calvanized Seamless Steel Pipe
1. Medium and heavy plate unit: It is an important production wide and thick plate for the production of straight seam submerged arc welded pipe, which is widely used in the main line of oil and gas high pressure transportation. 2. Furnace rolling mill: The furnace rolling mill includes a reciprocating roughing mill and a 4-roller to the finishing mill. 3. Semi-continuous rolling mill: including 1 rack furnace rolling mill and 5 rack finishing mill. On a semi-continuous rolling mill, the hot rolling experienced by the pipe in the finishing pass is substantially constant from one end of the pipe to the other. The time between the passes on the finishing mill is less than 3s on weekdays. The output roller road includes a laminar cooling system and a take-up station. On the furnace rolling mill, the thermomechanical history of the entire length of stainless steel stamped elbow fittings has changed significantly, especially in the production of micro-stainless steel stamped e...
