Problems solved by technology

This method is more effective for copper strips with small coil weights, but it is very difficult to operate when the coil weight exceeds 3 tons, because the final curled part will collapse, causing physical deformation and affecting the shape of the board

Abstract

The invention discloses a high temperature resistant antitack agent and a processing method before metal tape annealing. The high temperature resistant antitack agent is prepared by uniformly mixing the following components: by weight, 1-50% of a substance A and 50-99% of a substance B, wherein the substance A is at least one substance selected from the group consisting of aluminium hydroxide, alumina, calcium hydrate, calcium carbonate, calcium oxide, magnesium hydroxide, copper oxide, zinc hydroxide and zinc oxide; and the substance B is mineral oil or kerosene. The invention also discloses a processing method before annealing of a metal tape by the use of the above high temperature resistant antitack agent, comprising the following steps: uncoiling the metal tape and rolling, spraying the high temperature resistant antitack agent on the surface of a copper belt, crimping and annealing. The copper belt annealing antitack agent provided by the invention has an advantage of reasonable ratio, and can be used to solve the annealing bonding problem of a copper belt bell-type furnace. By the utilization of the copper belt annealing antitack agent provided by the invention, production processes are reduced.

Description

technical field [0001] The invention belongs to the technical field of metal surface spraying treatment, and in particular relates to a high-temperature-resistant anti-adhesive agent and a treatment method for metal strips before annealing. Background technique [0002] Copper and copper alloy strips are widely used, and their production is processed by rolling. Due to the deformation of the metal caused by the calendering process, a large stress is generated inside the metal, so an annealing heat treatment is required during the processing, and the metal is recrystallized at a certain temperature (high temperature) to eliminate the stress. [0003] At present, in the copper processing industry, the copper strip annealing heat treatment methods are mainly divided into air cushion furnace annealing or bell furnace annealing. Although the products produced by the hover furnace annealing process have stable performance and good quality, due to the large investment in equipment...
