Abstract
The invention discloses a copper strip annealing anti-sticking agent, belonging to the technical field of metal surface spraying treatment. The copper strip annealing anti-sticking agent has two forms as follows: (1) magnesium aluminum silicate and water; and (2) magnesium aluminum silicate, an assistant and water. Due to rational combination of the copper strip annealing anti-sticking agent, the problem of annealing cementation of a copper strip bell-type furnace is solved well. In addition, according to the copper strip annealing anti-sticking agent disclosed by the invention, distillation range of the technology is shortened; the original process including uncoiling, rolling and curling, re-uncoiling, degreasing, water-washing, anti-sticking agent spraying, curling and annealing is shortened into the process including uncoiling, rolling, anti-sticking agent spraying, curling and annealing. In comparison with the conventional technology, the copper strip anti-sticking agent disclosed by the invention has the advantages that: production link is reduced and production cost is reduced by more than 30%.
Description
Technical field
The invention belongs to metallic surface spray treatment technical field, be specifically related to copper strips annealing release agent.
Background technology
Copper and copper alloy band have a wide range of applications, and it is produced and adopts the mode of calendering to process.Because rolling processing causes flow of metal, metal inside produces bigger stress, thus the thermal treatment of will annealing in the course of processing, metal at a certain temperature (high temperature) recrystallize to eliminate stress.
Present copper processing industry, the copper strips heat treated mode of annealing mainly is divided into air cushion furnace annealing or bell jar furnace annealing.Air cushion furnace annealing is meant that copper strips is at rare gas element (N
2) or reducing gas (H
2) protection on-line continuous annealing down, uncoiling of copper strips, process annealing, a rolling.The bell jar furnace annealing is to go into the intensification under atmosphere protection of bell jar stove, constant temperature, cooling annealing to the copper strips package.
Air cushion furnace annealing is respond well, and because the annealing of copper strips single line, the high temperature bond phenomenon can not take place in copper strips, but the air cushion furnace cost is high, is that the less copper strips processing enterprise of general investment is difficult to bear; So some device fabrication merchants have developed some easy continuous annealing furnaces; The annealing device that has kept the air cushion furnace core; Equipment manufacturing cost significantly descends, but because equipment is simple, factors such as the size of body of heater, stopping property cause power consumption to rise; Although compare air cushion furnace decline has by a relatively large margin been arranged from cost, but still expensive.In some manufacturers that produces low and middle-grade relatively copper strips,, adopt the bell jar furnace annealing in order to practice thrift cost more; Because the bell jar furnace interior does not have continuous passage with the external world; Heat lost less, and every stove multireel copper strips of can annealing, production cost has had very big decline.
The mode of bell jar furnace annealing is exactly that copper strips becomes convolution code to go into intensification, constant temperature in the stove, lower the temperature, come out of the stove; Copper strips and copper strips under annealing temperature (260～600 ℃) bond; Especially the relatively low fine copper band (for example C10200) of fusing point bonds more serious; Uncoiling formed the copper strips distortion easily after such result caused annealing, and the template that has a strong impact on copper strips also is the microcosmic planeness of copper strips, causes the defective of product.In order to address this problem, traditional mode is to curl copper strips again to reduce the curling tension force of copper strips through coil opening machine before the annealing, just reduces the tightness between the copper strips.This method is more effective for the heavy copper strips of rouleau, but volume is very difficult to operation after heavily surpassing 3 tons, and the limit phenomenon produces physical deformation and influences template because last curled portion branch collapses.
In order to address this problem, some manufacturers adopt copper strips before curling, to smear the antiseized branch that is connected into, and mostly this antiseized composition is colloid silica, and concrete operation is with SiO
2Aqueous colloidal or the organic colloid surface that is sprayed onto copper strips, production technique is: uncoiling-rolling-curl; Uncoiling-degreasing again-washing-spraying release agent-curl-annealing.From technical process, in order to spray release agent, increased this procedure of degreasing, the flow process of production is elongated, decrease in efficiency, covert increase cost.If in the operation of rolling, spray release agent, the back that takes place again to anneal is cleaned clean and is caused surface quality to descend.
Summary of the invention
Problem to the prior art existence; The objective of the invention is to design the technical scheme that a kind of copper strips annealing release agent is provided, this release agent can directly apply in the operation of rolling, i.e. limit rolled edge spraying release agent; Rolling, spraying release agent is accomplished continuously; Technology becomes uncoiling-rolling-spraying release agent-curling-annealing, prevents copper strips bell jar furnace annealing adhesion problem effectively, and has shortened the technology boiling range of copper strips bell jar furnace annealing.
