Titanium alloy hot-rolled seamless pipe production system and production process thereof

Abstract

The invention relates to a titanium alloy hot-rolled seamless pipe production system and a production process thereof, belongs to the technical field of titanium alloy seamless pipe machining, and solves the technical problems of coating of coating layers, high production difficulty and low yield in the titanium alloy seamless pipe rolling process. The system comprises a piope blank heating furnace, a perforating machine, a transition reheating furnace, a three-roller pipe rolling machine, a online normalization area, a pierced billet reheating furnace, a tension reducing unit, a temperature adjusting tunnel, a straightener and a cold machine arranged according to a production process path in sequence; a pipe blank is unloaded for perforation rolling, pipe rolling, tension and diameter reduction, online hot straightening and cooling by the cold bed to prepare a finished titanium alloy hot-rolled seamless pipe; as electric heating furnaces are arranged in different phases in the rollingprocess, the quality of the pipe blank is guaranteed, and reasonable rolling temperature of the pipe blank is provided to the next procedure; brushing of protective materials is not needed in the rolling process, so that one procedure is reduced; and the rolling temperature is strictly controlled, so that the deformation resistance is reduced, the unit power consumption is reduced, the cost is saved, and the yield of titanium alloy pipes is improved.

Description

technical field [0001] The invention belongs to the technical field of titanium alloy seamless pipe processing, and in particular relates to a titanium alloy hot-rolled seamless pipe production system and a production process thereof. Background technique [0002] Titanium and titanium alloy seamless pipes are light in weight, high in strength, superior in mechanical properties, and good in corrosion resistance. They are mainly used to make aircraft engine compressor parts, structural parts of rockets, missiles, and high-speed aircraft, electrodes in the electrolysis industry, and power stations. Industrial manufacturing fields such as condensers, heaters for petroleum refining and seawater desalination, and environmental pollution control devices. Titanium and titanium alloy seamless pipes are mainly produced through three types of production systems: extrusion molding, pipe billet drilling and boring or diagonal piercing, cold rolling and cold drawing. Extrusion molding h...
