Problems solved by technology

At present, there are mainly two methods for preparing ultra-long and thin titanium/steel clad plates used in the chemical industry: the first type adopts the direct rolling clad method. The requirements on equipment, but its disadvantage is that the bonding strength is low, and the ability of the rolling mill is high, so it is not widely used in our country at present; the s...

Embodiment 1

[0026] Step 1. Perform shape correction treatment on the clad titanium plate 1 so that the unevenness of the clad titanium plate 1 is not greater than 1mm / m, and then heat treat the clad titanium plate 1 after the shape correction treatment at a temperature of 580°C for 2 hours, and then furnace cooling; the thickness of the clad titanium plate 1 is 3mm;

[0027] Step 2, cleaning and polishing the base steel plate 2 and the clad titanium plate 1 after heat treatment in step 1, so that the surface roughness of the base steel plate 2 and the clad titanium plate 1 is not greater than 3 μm; the base steel plate 2 The thickness is 10mm;

[0028] Step 3: Evenly arrange two supports 3 on the polished base steel plate 2 in step 2, then place the polished multilayer titanium plate 1 on the supports 3 in step 2, and finally place the explosive 4 on the on the multilayer titanium plate 1, and set the detonating charge 5 on the explosive, and carry out explosive welding to prepare the co...

Embodiment 2

[0035] Step 1. Perform shape correction treatment on the clad titanium plate 1 so that the unevenness of the clad titanium plate 1 is not greater than 1mm / m, and then heat treat the clad titanium plate 1 after the shape correction treatment at a temperature of 680° C. for 1 hour, and then furnace cooling; the thickness of the clad titanium plate 1 is 5mm;

[0036] Step 2, cleaning and polishing the base steel plate 2 and the clad titanium plate 1 after heat treatment in step 1, so that the surface roughness of the base steel plate 2 and the clad titanium plate 1 is not greater than 3 μm; the base steel plate 2 The thickness is 20mm;

[0037] Step 3. Three supports 3 are evenly arranged on the polished base steel plate 2 in step 2, and then the polished multi-layer titanium plate 1 in step 2 is placed on the supports 3, and finally the explosive 4 is placed on the support 3. on the multilayer titanium plate 1, and set the detonating charge 5 on the explosive, and carry out exp...

Embodiment 3

[0044] Step 1. Perform shape correction treatment on the clad titanium plate 1 so that the unevenness of the clad titanium plate 1 is not greater than 1mm / m, and then heat treat the clad titanium plate 1 after the shape correction treatment at a temperature of 640° C. for 3 hours, and then Furnace cooling; the thickness of the clad titanium plate 1 is 8mm;

[0045] Step 2, cleaning and polishing the base steel plate 2 and the clad titanium plate 1 after heat treatment in step 1, so that the surface roughness of the base steel plate 2 and the clad titanium plate 1 is not greater than 3 μm; the base steel plate 2 The thickness is 40mm;

[0046] Step 3. Four supports 3 are uniformly arranged on the polished base steel plate 2 in step 2, and then the polished multilayer titanium plate 1 in step 2 is placed on the supports 3, and finally the explosive 4 is placed on the support 3. on the multilayer titanium plate 1, and set the detonating charge 5 on the explosive, and carry out e...

Abstract

The invention provides a production method for an ultralong thin titanium/steel compound plate, which comprises the following steps: firstly, correcting the shape of a multi-layer titanium plate and performing heat treatment; secondly, cleaning and polishing a basic-layer steel plate and the multi-layer titanium plate after the heat treatment; thirdly, explosively welding the basic-layer steel plate with the multi-layer titanium plate to prepare a compound plate; fourthly, leveling the compound plate and mechanically cutting to guarantee that the compound plate binding fraction gets to 100%; fifthly, relatively superposing and assembling the steel surfaces of two qualified compound plates with the same sizes, and welding to obtain a blank; sixthly, rolling the blank; and seventhly, leveling and machining to obtain the ultralong thin titanium/steel compound plate. The method provided by the invention is lower in production cost and high in production efficiency; and the method adopts a combination method of the explosive welding process and the superposing rolling process, so that the using performance of the compound plate can be guaranteed and the length and the thickness of the compound plate also can be guaranteed. Therefore, the qualified ultralong thin titanium/steel compound plate can be produced by using a general rolling process only.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a preparation method of an ultra-long thin titanium / steel composite plate. Background technique [0002] As one of the country's pillar industries, the chemical industry plays an important role in the national economy and is directly related to people's daily necessities of life. Especially since 2008, my country's chemical industry will adjust and develop in multiple directions such as structural adjustment, low-carbon economy, and industry integration. According to US ACC estimates, China is likely to replace the US in 2011 as the world's largest chemical market. [0003] The anti-corrosion requirements of equipment used in the chemical industry have spawned a new type of titanium / steel composite plate. This titanium / steel composite plate has excellent anti-corrosion performance and high cost performance, so it will play its own advantages in the chemic...
