Embodiment
[0022] Embodiment: Preparation of stainless steel-carbon steel composite bar
[0023] 1) Billet making: Select 304 stainless steel pipe and Q345R carbon steel rod to form a billet. The size of the stainless steel pipe is 5mm thick × 60mm diameter × 2000mm long, as the cladding pipe 1; the carbon steel rod is 58mm in diameter × 2000mm long, as the mandrel 2 ; Clean the outer wall of the mandrel and the inner wall of the stainless steel tube until the metal base is seen; stack the cladding tube 1 and the mandrel 2, send them to the press for compaction, and use carbon steel to spot weld the two ends of the stacked composite billets first. Use submerged arc welding to package and weld, drill a hole at the end of the welded composite rod blank to vacuumize, and then close the hole to obtain a composite rod blank, such as figure 1 ; The arc-shaped corrugation height of the cladding pipe is 6 times of the thickness of the cladding pipe, and the corrugation width is 12 times of the c...

The invention discloses a process for rolling a metal composite rod with a corrugated bonding surface. The process for rolling the metal composite rod with the corrugated bonding surface is characterized by comprising the following steps of selecting a metal clad pipe and a core rod, cleaning the to-be-composited surfaces of the metal clad pipe and the core rod, and piling up the clap pipe and the core rod in sequence to make a blank, so as to obtain a composite rod blank; enabling the composite rod blank to pass through a Y-shaped three-roller rough mill provided with corrugated rollers, so as to roll for making a composite rod material with a corrugated composite surface; enabling the roughed composite rod material with an external corrugation to pass through a composite finishing mill, so as to roll corrugation on the external surface of the composite rod material to be round, and rolling the composite rod material to a needed diameter, so as to obtain a finished product composite rod material. By using the process for rolling the metal composite rod with the corrugated bonding surface, the bonding force between the core rod and the clad pipe is increased by utilizing the engaging force between the corrugation of the core rod and the corrugation of the clad pipe; the difference that the plastic deformation of metal is inconsistent, which is caused as the deformation resistance of dissimilar metal is different is overcome; the contact area between the core rod and the clad pipe is enlarged by utilizing the corrugated composite surfaces of the core rod and the clad pipe; the bonding strength of a metal layer is increased; the cracking phenomena of the core rod and the clad pipe in a rolling procedure are avoided; the composite rate is improved.
Description
technical field [0001] The invention belongs to the technical field of preparation of metal composite rods, and in particular relates to a process for rolling metal composite rods with corrugated joint surfaces. Background technique [0002] Bimetal composite bar is a metal bar composed of two different metals inside and outside. The outer metal tube is sheathed on the inner metal rod, and the outer tube and the mandrel are tightly combined through various deformation and connection techniques. When an external force is applied, the outer tube and the mandrel are deformed at the same time and the interface is not separated. The general design criterion is that the core bar meets the design stress, and the outer cladding can resist corrosion or wear. Compared with single metal rods, composite rods make full use of the best performance of mandrel and cladding tube, not only has high strength, but also has excellent corrosion resistance and wear resistance, which saves a lot o...
