Abstract
The invention discloses a manufacturing method of a calendered complex titanium clad steel plate used in a pan. The method comprises the following steps: taking two low carbon steel plates which have a carbon content lower than 0.15% and are 8-12mm thick and two titanium plates which are 2-3mm thick; polishing one surface of the steel plates and the titanium plates, and superposing the steel plates and the titanium plates by arranging the polished surfaces face to face in a four-layer order of steel-titanium-titanium-steel; sealing peripheral gaps between each two plates by fusing while pressfitting; heating clad billet plates to the temperature of 850-920 DEG C; calendering and cladding by a hot roll to cause a deformation rate not smaller than 65%, and then diffusion annealing at the temperature of 750 DEG C to remove oxide layers on the surfaces; cold rolling and calendering at the deformation rate not greater than 10%, and then relieving stress at the temperature of 650 DEG C; separating the four-layer superposed plates to obtain two calendered complex titanium clad steel plates used in the pan. The method helps manufacture the titanium clad steel plate by heating and calendaring the low carbon steel and the titanium which are produced at high temperature and have low brittleness; atoms on a titanium-steel interface are diffused with each other at the eutectic temperature to realize metallurgical bonding; the steel plates of the titanium clad steel plate are closely clad by the titanium plates of the titanium clad steel plate; the bonding strength of the titanium and the steel is high, thus the titanium clad steel plate is an ideal complex plate for the pan.
Description
Technical field
The present invention relates to a kind of manufacture method of composite plate, particularly a kind of pan manufacture method of titanium steel composite board.
Background technology
Pan is the apparatus of cooking food, pan in use, the stove and accessory of the bottom surface of pan contact high temperature, the inside contacting foodstuff of pan.Pan is to make with metal material processing, be to make mostly with sheet metal, pan metal material desired strength height, good rigidly, thermal conductivity are good, high temperature resistant, corrosion-resistant, specious, the material of the health that can not exert an influence when using, and what have also wants magnetic conductivity good.Homogenous materials such as present pan has cylinder iron, steel, aluminium, stainless steel are made, these Material Physics, chemical property difference, the pan performance difference of making is bigger, and can main performance difference be produce when thermal conductivity, corrosion resistance and use on the harmful material of health.In the above-mentioned material, the thermal conductivity of cast iron and steel is better, corrosion resistance is relatively poor, cylinder iron the pan made from steel has a spot of ferro element stripping in use and enters in the food, there is good booster action edible back to preventing and treating hypoferric anemia, if but the too much iron oxide of absorption of human body can produce harm to liver; The thermal conductivity of aluminium and corrosion resistance are better than cast iron and steel, the pan that is formed from aluminium has a spot of aluminium element stripping in use and enters in the food, edible back aluminium can be accumulated in the brain, cause the cranial nerve degeneration, have a strong impact on people's behavior and intelligence, how aluminium element has accumulated easy trouble senile dementia in human body; Stainless corrosion resistance is better, and the pan of making is attractive and durable, but stainless thermal conductivity is poor slightly, price is higher, and there is the hidden danger that influences health in underproof stainless steel, the pan made from underproof stainless steel, some compound wherein can enter in the food in stripping in use, accumulation in vivo when reaching a certain limit, will be detrimental to health after edible, underproof stainless steel is generally chromium and exceeds standard, chromium is heavy metal, enter human body after, influence health.
The bottom of a pan of pan is different with the instructions for use of pot the inside, and in order to satisfy different needs, the compounded composite plate of useful different metal material is made pan.Make in the composite plate of pan, maximum is steel and stainless steel clad plate, the steel and the stainless steel capital are steel, be easier to compound, the price of steel is low, intensity is high, good rigidly, high temperature resistant, thermal conductivity good, it is a kind of cladding material of the desirable pan the bottom of a pan, the stainless steel corrosion resistance is better, attractive and durable, can be used as the inner layer material of making pan pot the inside, it is better to make the pan combination property with steel and stainless steel clad plate, but because there is the above-mentioned hidden danger that influences health in stainless-steel pan, steel and stainless steel clad plate are not very desirable pan composite plates.
In metal material, the intensity height of titanium, specious, stable performance, corrosion-resistant extremely strong, do not react, at the medicine equipment that medically can be made into used inside human body or substitute organ with human body, be called as one's own thing metal, be the inner layer material of a kind of desirable pan pot the inside, but titanium being the higher metal of a kind of price, is that outer, thin titanium plate is that the composite plate of internal layer is the desirable composite board of making pan with steel plate.
Titanium and steel are two kinds of metals that physics, chemical property differ greatly, and be compound difficult.In the prior art, the titanium steel composite board that useful blast complex method is made, compound tense is to be stacked together with thicker steel plate and the titanium plate that approaches, and makes titanium plate and steel plate be combined into composite plate blanks with the method for exploding, and with milling train composite plate blanks is rolled required thickness then.This with the compound titanium steel composite board of blast, the composition surface of titanium steel has the intensity of combination of ripple, titanium steel lower.The thickness of the required sheet material of pan is less, generally be 1.5 millimeter, because the price of titanium is higher, the system pan should be thin as far as possible with the titanium flaggy of titanium steel composite board, generally is 0.2 millimeter, with milling train composite plate is rolled the required thickness of pan after, bigger ripple place titanium flaggy has steel and exposes a little on the composition surface, make the titanium plate not tight to the cladding of steel plate, the bond strength of titanium steel is low, is easy to generate faying face separately.
Summary of the invention
