Embodiment 1

[0039] The rolling method of an explosive composite titanium-steel-titanium double-sided clad plate of the present invention is characterized in that: comprising the following steps:

[0040] Step 1: Making blanks:

[0041] Using titanium plate doubler plate, steel plate substrate and titanium plate doubler plate, the three are explosively welded to form a titanium-steel-titanium double-sided composite slab; in the first step, the titanium plate doubler plate uses TA1 as the cladding material, The thickness is 3mm, and the steel plate base plate is made of Q235B steel. Both the upper surface of the steel plate base plate and the lower surface of the titanium plate doubler plate are polished and pretreated, and then a protective layer is coated on the upper surface of the titanium plate base plate, and the protective layer is uniform Arrange TNT explosives. After detonation, the titanium cladding plate and the steel plate base plate are welded together by the instantaneous high...

Abstract

The invention discloses a rolling method for an explosive cladding titanium-steel-titanium double-faced composite board. The rolling method includes the following steps that firstly, a blank is manufactured; secondly, the blank is checked and accepted; thirdly, a rolling technology is conducted; fourthly, cooling is conducted; fifthly, flaw detection is conducted; sixthly, cutting and sampling are conducted; seventhly, marking and checking are conducted; and eighthly, warehousing is conducted. According to the rolling method for the explosive cladding titanium-steel-titanium double-faced composite board, the double-faced composite board blank with large residual stress after explosive welding is sufficiently heated in a walking beam type heating furnace through a low temperature preheating mode and a medium and low temperature heating mode, the heating cost is low, and the pollution to the environment is small; and the technical purposes that the double-faced composite board high in combination strength can be rolled with a 2.5-time low compression ratio and with the online straightening temperature controlled to be 400-450 DEG C, offline straightening is not needed, and the flaw detection grade of the combined parts of upper and lower titanium composite boards and a steel plate base plate reaches the JB730-2005 I level are achieved.

Description

technical field [0001] The invention relates to a rolling method of explosive composite titanium-steel-titanium double-sided clad plate, in particular to a double-sided clad slab formed by explosive welding of titanium clad plate, steel base plate, and titanium clad plate directly through low compression The invention relates to a rolling method for forming a double-sided composite plate by rolling, which belongs to the technical field of composite materials. Background technique [0002] Titanium is a transition metal with low density, excellent low-temperature toughness, and outstanding corrosion resistance, but its application is greatly limited due to its high price. In order to reduce the cost of use, it is usually made into titanium-steel composite plate. Titanium-steel composite material is widely used in chemical industry, petroleum, marine industry because of its high strength of steel and excellent corrosion resistance of titanium and significant economic benefits....
