Description
Technical field
The invention belongs to metallic surface spray treatment technical field, be specifically related to the preceding treatment process of a kind of high temperature resistant release agent and metal strip annealing.
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.The product that air cushion furnace annealing process mode is produced, though stable performance, quality is better, because the equipment input is bigger, and production cost is higher relatively, so the air cushion furnace annealing process mainly is confined to state-owned enterprise or large-lot producer.The bell jar furnace annealing is that the intensification under atmosphere protection of bell jar stove, constant temperature, cooling annealing are gone in the copper strips package.Because bell jar stove heat is lost little, batch is big, and production efficiency is higher relatively, and production cost is less relatively, and many middle-size and small-size manufacturers in order to save cost, adopt the bell jar furnace annealing more.
The mode of bell jar furnace annealing is exactly the stack of copper strips rolling, pack into intensification, constant temperature in the stove, lower the temperature, come out of the stove, copper strips and copper strips bond down for 240～600 ℃ in annealing temperature, especially T2 fine copper band bonding is more serious, the result causes the copper strips uncoiling of annealing later, and surface wrinkle seal is serious, has a strong impact on the template of copper strips, be the microcosmic planeness of copper strips, cause the defective of product.In order to address this problem, traditional mode is to pass through coil opening machine curling copper strips again before the annealing, to reduce the curling tension force of copper strips, 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, the limit phenomenon because last curled portion branch collapses, generation physical deformation and influence template.
