Description
Technical field
The present invention relates to a kind of hot-rolling method, the heating means of especially a kind of big substance titanium base of big thickness.
Background technology
With the development of science and technology, especially industrial expansions such as aerospace, ocean development, chemical industry, automobile, titanium
The demand of material significantly rises.But since China's titanium industry is started late, start within 1958 the industrial metaplasia for realizing titanium sponge
Production, the industrialized production for realizing titanium processing in 1964, until annual titanium processing capacity in 2004 just breaks through 10000 tons, far
Less than the demand in domestic titanium market.
Titanium processing enterprise of the country uses resistance furnace to carry out heating production substantially at present, which can only be to small dimension base
Material, small substance titanium base carry out heating production, cannot achieve the consecutive production of big specification titanium base.And it is small dimension blank, small
The titanium base of substance can not produce area substantially, ultra-wide（3000mm or more）The titanium plate that equal special dimensions use.
Invention content
The technical problem to be solved in the present invention is to provide a kind of heating means of the big big substance titanium base of thickness, with continuous production
Area substantially, the titanium plate of ultra-wide.
In order to solve the above technical problems, the technical solution used in the present invention is：The titanium base soaking type heating furnace into
Row heating；It is 10~12 to control the flow-rate ratio of heat gas air and coal gas in soaking type heating furnace；The holding temperature of titanium base exists
950 DEG C~980 DEG C.
Titanium base charging temperature of the present invention keeps the temperature 2~3 hours at 500~600 DEG C；Then 60min and within heat up
To 900 DEG C；Finally 14~17 hours are kept the temperature at 950 DEG C~980 DEG C.
Titanium base specification of the present invention is：480~500mm thickness, 17~21 tons of substance.
It is using advantageous effect caused by above-mentioned technical proposal：The present invention is used in mixed gas（Coal gas and air）
Heating environment, produced in soaking type heating furnace, it is ensured that the uniformity of the continuity and titanium base of production heating improves production effect
Rate；By rational heating cycle, ensure 21 tons of maximum 500mm thickness, substance titanium base homogeneous heatings.The present invention realizes big thickness
The batch heating production of big substance titanium base, and coordinate present-day mill, it can Direct Rolling width 3000mm or more, 20 meters of length
The titanium plate of the above special requirement, and improve the lumber recovery and production efficiency of titanium.
Method using the present invention carry out production realize maximum gauge 500mm, 21 tons of substance titanium base heating, steel plate
After heated, big thickness blank both obtained and had been evenly heated, and met the needs of follow-up Rolling Production special requirement titanium and carry
High efficiency.
