Embodiment

[0026] see figure 1 , a production method of hot-rolled titanium plate, the method comprises the following steps:

[0027] Step 1: The titanium slab is heated by heating furnaces #1 and #2, and then the furnace-grown iron oxide formed on the titanium slab due to heating is removed, and then the titanium slab is sent into the rough rolling device by the roller table. Among them, the temperature of the titanium slab out of the furnace is controlled at 878°C to 882°C.

[0028] Titanium is a metal with very active chemical properties. At high temperature, the affinity between titanium and oxygen is extremely strong. At the initial stage of heating, oxygen enters the lattice on the surface of titanium to form a dense oxide film, which can prevent further diffusion of oxygen to the substrate. When heated above 500°C, the oxide film of titanium becomes porous, thickened and easily peeled off. Oxygen diffuses continuously to the substrate through the pores in the film, forming a hard...

Abstract

The invention provides a hot rolling titanium plate production method and system. The method includes the steps of firstly, heating a titanium plate blank, and feeding the same to a coarse rolling device after iron oxide generated by a furnace is removed; secondly, by the coarse rolling device, coarsely rolling the titanium plate blank to allow the thickness of the middle of the blank to 25-40mm, and then feeding the same to a hot coil box; thirdly, uncoiling with an uncoiling arm, using a head cutting flying shear to cut the irregular head into an arc shape when the head of the titanium plate blank is guided out, and then feeding the same to a fine rolling machine set for fine rolling; fourthly, continuously rolling the titanium plate blank into finished titanium strips through the fine rolling machine set which comprises seven total hydraulic four-roll rolling machines, and feeding the strips to a laminar cooling device for cooling; fifthly, coiling the titanium strips in a coiling machine to form titanium strip coils. The method has outstanding advantages that the method is simple and high in automation level, and yield and production efficiency of the titanium strip coils can be increased by accurate control of each link.

Description

technical field [0001] The invention relates to the field of titanium plate production, in particular to a method and system for producing a hot-rolled titanium plate. Background technique [0002] Titanium and titanium alloys have many characteristics such as low density, high strength, corrosion resistance and high temperature resistance, and are the most promising new structural materials. Titanium coils are mainly used in high-tech fields such as large civil aviation airliners, military aircraft, aerospace vehicles, nuclear submarines, and nuclear power plants. Titanium coil is made of high-quality sponge titanium as raw material, and the titanium plate is produced in the form of coil, and the width of the coil is usually more than 1000mm. There are many special uses of titanium strips and coils. For civil use, there are mainly pure titanium wide plates (width greater than 1000mm) required by chemical industry, metallurgy, electric power and other industries, titanium p...
